GTK2 won't compile in Lazarus... I didn't realize the n800 was GTK2 -
all the docs I've seen mention "GTK Toolkit" and don't specify.

Building the LCL for GTK2 for ARM result sin "Internal error 200408162"
at line 277 of gtkwscomctrls.pp.

The line reads:
gtk_progress_configure(GTK_PROGRESS(Pointer(Pointer(wHandle))),Position,Min,Max);

I tried the good old trick of just hitting "Build" again (took off build
clean) but it still generates the same FPC internal error.

On that note, it still won't find libglib.  On the device is only
libglib-2.0.so so I assume ppcarm is trying to link to libglib-1.2 or

Aha!  I've copied the /lib directory off the device and onto my desktop.

It still wouldn't find it.  There was no link from libpthread.so to
libpthread.so.0.  I made that link and it worked.

If I do this, is the app going to require those .so links to .so.0 on
the device?  If so that's a problem... is there any way around this?

I did a search on the device and find /lib/libpthread.so.0 on it.

Should I copy these off the device and onto my development machine for

I've compiled my first console program for arm-linux and ran it on my
Nokai n800 tablet.

I downloaded arm-linux-fpc-2.0.4.i386-linux.tar from ftp.freepascal.org
and installed it.

I created a simple console app and ran the following at a command line:

ppcarm -Xd -Sd -XParm-linux- project1.lpr

Worked like a charm.

Placing those options in the "additional options" for the compiler
options in Lazarus also works, though setting processor to "arm" and os
to "linux" didn't do it for me.  I have no clue what those params mean -
copied it off a website.

I'm unclear of how to get the LCL built for ARM... if I try this to

Trying to compile the same graphical app at a command line complains it

Something else, I seem to get left mouse button messages twice for every
click.

Using:

  procedure WMLMButtonUp(var Message: TLMLButtonUp); message
LM_LButtonUp;  

It calls this procedure twice for every right mouse release.  GTK+ only
does it once, so I don't think it's my code.

[lazarus] Shift+Tab doesn't work as expected?

[Tony Maro]

Tab through components on a form works fine.  Shouldn't shift-tab go
backwards through the same list?  Mine jumps around just the buttons on
the form with shift+tab and skips most of the text boxes.

Yes, I've set my taborder correctly.

Tested and got the same results with both GTK+ and GTK 2.  Can't test
Win32 at the moment.

[lazarus] Wow, Kudos to the GTK2 team whoever you are!

[Tony Maro]

I've finally got "The ORIGINAL Lazarus built application" (TM) (hehe) --
originally started in June of 2002 -- built and running in the latest
stable Lazarus.  It hasn't been compiled on a recent Lazarus in
something like three years.  It's amazing how many changes there have
been to the unit structure, LCL and FPC itself.

And, it compiled and ran just the same in GTK 2, so I'm excited to be
able to release a GTK 2 version of it!  The only interface change I had
to make was making some of the buttons slightly larger to accommodate a
pretty standard GTK 2 theme.  And I must say, the fonts are gorgeous.

I did however have one form that if I showed it modal, closed it, and
showed it modal again would crash the app.  I changed it to dynamically
create the form just prior to showing it to fix the problem.

I still have some cleanup work to do, and rewrite all the sound code so
that it will function again, so it will probably be another week or so
before I actually release an update.  But, I think I'll try balancing my
checkbook with the new version tonight just to see how it does.

Scratch that - I can't reproduce it on a fresh form.  It's gotta be
related to the form design itself in my app somehow, but if forward
tabbing works I can't see why backwards tabbing wouldn't.

Of course this is CheckBook Tracker, which I started writing back before
the Lazarus form designer was stable ;-)  It's a hodge podge of
workaround through the ages to make things work with a broken Lazarus or
a broken FPC (or my own broken code for that matter!)

[lazarus] Odd text file problem

[Tony Maro]

I'm updating CBT to compile with the latest Lazarus and I'm having
problems with my file generation routine from inside a component.

It calls:

procedure TChkPrinter.PrintChecks;
var
MyFile: TextFile;
FileName: String;
// extraneous info removed
begin
// more extraneous info removed
Filename := '/tmp/cbtrack.ps';
AssignFile(MyFile, FileName);
rewrite(MyFile);
writeln(MyFile, '%!PS-Adobe-3.0');
writeln(MyFile, '%%Creator: CBT');
writeln(MyFile, '%%Title: Checks');
writeln(MyFile, '%%Pages: (atend)');
writeln(MyFile, '%%PageOrder: Ascend');
writeln(MyFile, '/AvantGarde-Book findfont');  

// more extraneous info removed
closefile(MyFile);
end;

The problem is there is no error, and it does NOT create the file.  I've
tried various paths, I've pasted this code into a new form and it works
fine.

How can I figure out what's (not) going on if there's no error
generated?

[lazarus] IDE dialog position question and the IDE

[Tony Maro]

I run dual monitors, with a desktop size of 2560x1024

Nearly every "dialog" used by Lazarus is set poDesktopCenter, which
splits right down the middle of my two monitors, leaving half the dialog
on each monitor.

Is there anything that can be done to change this?  Almost every piece
of Linux software I run that pops up a centered dialog centers it to one
monitor or the other automatically...  Windows is another story, I can't
get a darn thing to not bridge the center of the screen in Windows lol.

I've tried every window position known to man with a test form...

poDesktopCenter and poScreenCenter both do the same thing for me in both
GTK1 and GTK2.  They place the form centered vertically and pushed up
against the edge of the screen at the split, but it doesn't split across
both screens.  So, for a window, I am unable to reproduce what's
happening with the IDE.

Dialogs I open such as showmessage() still bridge the center.

[lazarus] New component: TMMobileBar

[Tony Maro]

So I got a wild hair today and did something I've been wanting to do for
a while.

I was inspired by this screenshot of possible MID's (Mobile Internet
Devices) that run Linux:
http://www.linuxdevices.com/files/misc/intel_redflag_MIDinux_UI.jpg

I liked the nav bar on the middle screenshot, and decided to replicate
the feel of it in a Lazarus component.  I designed the component to work
with touch screens, so you can click and drag to slide around the bar,
but no mouseover events are used.  It's a TPanel descendant that lets
you load graphical buttons onto it.  The buttons can be any width or
height, and don't have to be uniform:

http://tony.maro.net/ossramblings/tmmobile.php

Captions are optional and you can make it any size.  The screenshots
don't really do it justice - you have to drag the bar around to get the
full experience.

Is anyone doing PocketPC devel out there?  This would be a great gadget
for it.  You could use it like I did as a launcher, but it could easily
display thumbnails of images for an image viewer, even for desktop PC's.
The background colors are customizable.

I'm excited, because if any MID's are actually released that run Linux
and have GTK, Lazarus would be an awesome development environment for
new applications!

[lazarus] Working on my components again

[Tony Maro]

I got a Google Alert that said someone was having trouble finding my
components for Lazarus.  I changed my blog software and never finished
migrating all my old links over.

I've just thrown up the first page that posts my tmpack of components:

http://tony.maro.net/ossramblings/tmpack.php

It's been slightly modified since the old version, mostly to be
compatible with the latest Lazarus.  I have _not_ tested every component
under the latest Lazarus yet, so there may be issues.

I'll be putting up the rest of my stuff soon.  The original files are
all still there, but there's no links on my site for downloading them
yet.

My next step is to fix the CheckBook Tracker components (for CBT version
1) to work in the latest Lazarus, and fix a few user interface issues in
CBT 1 that have annoyed me.  I doubt I'll have time yet to continue work
on CBT 2, but maybe this will be a good holdover.  I'll also plan to
make CBT more cross platform with this next release so it will compile
in Windows (and maybe OSX) without major hassle.

What extra actions should the end-users perform if the application uses sqllite
or embedded-firebird ?   If would be even cleaner because the database
is a single
file instead of a directory full of dbf and ndx files.



I must state I've never used sqllite or embedded firebird.  My issue with firebird is the additional libraries you must install - which isn't a big deal in Windows, but due to dependency hell I stay away from anything requiring extra's.  Does sqllite require extra libraries?  One of my key enjoyments of TDbf is that there's nothing else, it's all implemented within the Pascal code.  I never have to think about if libraries registered properly or something in the OS overwrote my version with a newer or older version.  This also reduces end-user tech support issues in my experience.  But again, keep in mind I'm talking about a single-user application compiled for both Windows and Linux.

The other DB devel I do is almost all what I would call an "application appliance" - a LAMP rack mounted unit with entirely a web based interface.  On that note I'd LOVE to see a series of Lazarus frameworks for implementing an Ajax application...  That stuff is hard to code!

Its a question of the right tool for the job, not a question of is a screwdriver superior to the hammer.  Each tool fits a different use.

I'd use TDbf for a networked 5 user LAN environment, but if you want something that works under more latency, for instance over the Internet, or if you have more users you'll probably want a client-server transaction based DB model.

If you want a single user application (or a few networked users) that is database enabled and doesn't require the end-user to know how to set up a database server, then products like TDbf are the answer.

This discussion seems reminiscent of old discussions over networked use of Paradox versus going with... what was the C/S database engine Borland supplied?

So if you want to compare TDbf you'd compare it against text-file based database engines, Paradox, dBase components, etc.  Other than the possibility of porting an old open-sourced text-file database engine for Delphi, I think TDbf is probably unique in it's class for Lazarus support.

As a producer of commercial software for non-technical end-users, I'd never consider producing a MySQL, Firebird or MsSQL application.  The end-user level of expertise is too high for my market.  With TDbf I only have to let the user pick a directory to store the data in, and provide an easy way to do backups.

On the topic of embedded firebird, I've never used it in Lazarus (is it even available and stable in Lazarus?) but the comment on their website "The embedded runtime is < 2 MB" is reason enough for me to stick with TDbf.  My total app with TDbf is smaller than that.

Not scalable ? In what way ?

TDbf rulezzz ;-)



Says the author... lol.

Actually though, I'm running a TDbf based app with around 300,000 records total (across multiple tables) and performance is excellent.

The real problem in scalability is that it's not a true transaction based system, and if your app or PC crashes it has a tendency to corrupt the database.

But, for an individual application needing to store data it's wonderful!  If you're looking for multi-user with multiple database server backends, it's not the product for you.

Maybe this because of the 32767 limit?

 


Well, there was that too, but even before that I ran into glitches.  Of course let's remember I wrote that... wow, 3 years ago.  Things may have changed a bit since then.

I have some parameters in the ProjectOptions. I want them to be saved in the

I've seen something like "SomethingHasChanged", but my guess is that there

I've done that... inherit from TScrollingWinControl that is.  The check register component in CheckBook Tracker used that method.  I needed a scrolling win control, but needed the scrollbar to handle many thousands of entries, and I wanted to custom draw the entire of the window based on the scroll position.  The default component always sized the scrollbar wrong, and wouldn't truly scroll from zero to the end - it would never go to the edges of the range.

I found the built-in scrollbars for TScrollingWinControl to be totally useless for anything other than scrolling a canvas.

[lazarus] Windows 2003 Server

[Tony Maro]

I just installed a snapshot of the Windows Lazarus with FPC on a Windows 2003 Server.

Everything installed fine and Lazarus started with a blank project, but when I try to open an existing project it will invariably crash.

It's always "Access violation" and happened to me on both TGroupbox and TNotebook.

I installed the same Lazarus image on an XP Pro box and opened the same projects with no error.

Is this a known issue?

Thanks,
Tony

I used Thunderbird for probably 2 years until last month when I installed an Exchange server at the office.  Then I switched to Evolution.  The new Evolution is nice, but the trouble you are having is simply configuration issues with T-Bird, not a problem with the app.

My install did not default HTML mail OR receipt requests, so I can't say why yours did.

I loved the spam filters in Thunderbird, and the PGP / GPG support is the best around.

Maybe this will help.  It's probably pretty nasty code so I should be
embarrassed for posting it.  It does work for me however.

Instead of returning an array, I ask for a specific field position,
providing the complete CSV line, and it returns the contents of the
field.  It also is able to detect if a field was too small - something
specific to my project that could be removed (ala ShortFields.)  This
assumes the American / Microsloth method of comma-quote delimited which
I've recently learned is not all that standard.

It also won't handle lines greater than 500 characters by design... so
keep that in mind.

function GetField(AData: String; AField: Integer; var shortfields:
Boolean): String;
var
  TempStr: String;
  Quote1Pos, Quote2Pos, SepPos: Integer;
begin
  // give a field number, return the contents
  ShortFields := False;
  TempStr := AData;
  while AField > 0 do begin
// skip over a field...
if copy(TempStr,1,1) = '"' then begin
  TempStr := copy(TempStr,2,500); // drop the quote
  TempStr := copy(TempStr,pos('"', TempStr)+1,500); // drop to the
next quote
end;
TempStr := copy(TempStr,pos(',',TempStr)+1,500);
AField := AField - 1;
if length(TempStr) < 2 then begin
  shortfields := True;
  result := '';
  exit;
end;
  end;
  // grab the data...
  if copy(TempStr,1,1) = '"' then begin
TempStr := copy(TempStr,2,500); // drop quote
TempStr := copy(TempStr,1,pos('"',TempStr)-1);
  end else begin
TempStr := copy(TempStr,1,pos(',',TempStr)-1);
  end;
  Result := TempStr;
end;

Actually, here's the line giving the error:

if i_Error <> 0 then
begin
d_SalesTax := 0;
end; <---line that is giving me the error
 else 

Remove the semicolon before else.

What you're saying is:

if [something] then {block};
else

What you should be saying is:
if [something] then {block} else {block};

Common mistake.  Keep in mind that the semicolon goes at the end of a
complete statement.  In this example your complete statement INCLUDES
the else keyword, so it's semicolon goes after that.

One more caution for you.  Ubuntu / Kubuntu doesn't install many devel
libraries by default.  When you go to compile Lazarus the first time you
are likely to get many errors regarding linking to libraries.  Use the
Synaptic package manager (it should be there by default for Kubuntu) to
find the missing packages and install them.  For instance, you will need:

libgdk-pixbuf-dev

But it will complain about "gdk-pixbuf" not linking if you don't have
it.  The above package solves that.  You can generally find what devel
library is missing when you try to compile Lazarus if you look at the
FIRST error in the long list of errors and warnings when you try running
Make.

You'll probably also need to install:

libgtk1.2-dev
libglib1.2-dev
libx11-dev
libxi-dev
libxext-dev
libxau-dev

and any other packages that Synaptic suggests when you choose these.

I know all this from experience... I'm running Ubuntu 5.10 for i386 on
all my devel machines.

Try  "procinfo"

Whatever package you need that has that, I have no idea.  In Debian the
package is "procinfo".

That shows you what is using what IRQ's and more.

Wasn't IRQ 11 commonly used with sound cards?  Do you have working sound?

Possibly neither.  Kubuntu is Debian based, so you'll want to either
install binary packages or use .deb files if possible.  I've seen
sporadic reports of alien having trouble with converting the .rpm files
to .deb for use in Ubuntu/Kubuntu and other Debian derivatives.

If you DO use those two packages, you'd first use "alien" to convert
them to .deb files, then install those.

You could also download the FPC binary installer and source for Linux:

http://sourceforge.net/project/showfiles.php?group_id=2174

Extract the tar file using your favorite tool, or at the console with:
tar -xvf fpc-2.0.2.i386-linux.tar
(You'll want it already in a new folder before you start.)

Once extracted, do this:
sudo ./install.sh

That will install the FPC binaries, and I believe will create the
default /etc/fpc.cfg file for you as well, so you will be ready to go
afterwards.

After installing FPC binaries, get the Lazarus source and compile it. 
You'll need the FPC sources to match your compiler for Lazarus to work
properly, just like in Windows.

Others might disagree.  I'm sure it seems like a bit much, especially if
you aren't that familiar with Linux, but you'll learn a lot in the
process too.

Alexandre, keep in mind that Lazarus is designed to be cross-platform. 
Each operating system handles focus a different way, and in Linux, each
window manager handles focus a different way making it even more
complex.  That's why it's separated from the actual component and in the
"interfaces" portion - to abstract the OS specific code from the typical
developer's code.

With Lazarus designed to compile the same code for Windows, Linux, OSX
and more, it's much more complex.

I know this isn't what everyone is really wanting to hear when they're
discussing this, but I'll add my $.02 USD into the discussion more from
an esoteric corporate view than a lazarus coding view.

I wrote TruckBytes using Lazarus.  It's a full featured graphically
pleasing database application designed to run a trucking company.  The
total download is around 2 MB compressed, including the SSL libraries I
redistribute. 

An equivalent program written using Visual C++ in a Microsoft
environment would never see the light of day for less than 20 MB.  The
database engine alone would probably be 3/4 of the total distributed
program.  If done in VB, the runtimes for VB alone would be large.  Sure
you could force your users to download it separately, but if you want to
reduce customer support issues you distribute everything you need.

Back to TruckBytes.  The EXE is around 3.9 MB all said and done, plus
supporting SSL dll's for the Windows version.  I have 200 GB of hard
disk space.  I have 2 GB of RAM.  I have 3 Mb download speed.  If I was
a nut about trying to reduce EXE size I'd use a macro assembler and a
6502 processor (yes, I've done that before.)

"Bloat" used to be an issue in code when the code was pushing the limits
of what the computers could handle.   Sure you can talk about "bloat"
like it's still a horrible problem, but when it comes down to it the
question is do I want to waste 4 months or more of development to reduce
code size or use some preconfigured "lego blocks" that produce a larger
EXE?  I'll go for the 4 months of man-hours saved.

Of course that's a corporate view and really holds no bearing on the
discussion of how to reduce the LCL size, I just want to point out that
1 MB exe versus 4 MB exe really doesn't make a darn bit of difference
unless your computer was built in the mid 90's.  Or you're simply
writing a console app, in which case you shouldn't use the LCL anyway.

Keep in mind I'm not saying use this to justify NOT optimizing the LCL
or smartlinking.  I'm just saying weigh the time spent coding where it's
best utilized, for instance GTK2, QT, OSX, better compatibility or bug
squishing.

The above statement's obviously don't apply if you're writing for
PocketPC / Windows Mobile.

If someone will pin down what would need done, I would even throw it in
a non-visual component so that it could be embedded within distributed
applications - you wouldn't want to just do it by default, but give the
user the option in the settings dialog or something.

Obviously the name C++ is why it's so commonly used.  Wait, that doesn't
make sense...

What we have in Lazarus is essentially "Visual Studio Pascal" (not that
I'm suggesting that name because it's mostly taken.)

But, I honestly don't think a name change will affect things much one
way or the other.  Like was already pointed out "Delphi" had nothing to
do with Pascal - probably because Borland was smart enough to realize
that Pascal was already viewed as an obscure dead language and they
wanted to separate themselves from that.  Nobody in the early days
called themselves "Pascal" programmers, they were all "Delphi" programmers.

Okay now I'm curious... what KIND of sexual tastes?  Never mind.  Sorry
I asked.  And I agree - if you're going to take offense at a project
name, why the heck do you use SATAN for scanning your network? ;-)  Or
is that SAINT... lol

I agree that changing the name needs to be seriously considered.  We
recently went through the same question regarding my company name. 
Finally we came to the conclusion that we got better brand recognition
with the current name even though a new name might fit our service
offerings better.

I mean, how many people really know what 3M stood for?  Originally it
was a VERY poor choice for a name considering what they end up selling
now (i.e. post-it notes.)  But, they have enough brand recognition if
they tried to change it, it would be disastrous.

So the question is, do enough _programmers_ know what Lazarus is to
dissuade a name change?  Or is it still obscure enough that we'd get
more recognition from a more targeted name?

Well my simple workaround was to watch for a draw event called with
itemindex of -1.  However, I think it does signify something wrong with
the GTK Widget.  Obviously there's no reason to draw an item in the
listbox that has an index of -1.

Mine was GTK1 and the TListBox using custom drawing.

Not that this helps, but it was introduced as a bug in the past 8 months
or so.  Code compiled on FPC / Laz from over 8 months ago didn't
experience this problem.  I just updated FPC+Laz and working code from
before started crashing.

Hehe, I never said I was sad.  When I first started using Lazarus the
instructions included "Do not attempt to use the form designer" because
it was severely unstable - every component had to be created at runtime
in code.  ;-)  Things have come a long way since then.

Here's a test project for both QT and GTK2.  It includes a Tbutton, a
Tpanel, a TMemo and a TLabel.

NOTE: I may have left it set to build for QT last... check widget set
before compiling.

http://www.maro.net/lazarus/testinterfaces.tgz

Both QT and GTK2 have the z-order / transparency problem.

I've set a label with an 8 point Helvetica font.  If you don't have
Helvetica, you might want to change it to something else.  In GTK2 the
font shows HUGE - like 150 point or something, and regardless of what
font you tell it to be ends up being the same font.  The point size DOES
affect it, but you can't get it lower than an effective 100 point or
so.  It will go much larger.

In GTK2, a default formatted label displays fine - it's just anytime you
try to set the font.  The problem of font size also occurs if you are
manually drawing on a TCanvas using onpaint.

In QT the label doesn't appear at all, even if you just go with the
default font.

In QT it seems to run, but when you X to close the app, a huge empty
window appears on top of everything and the console shows crash information:

[lazarus] Interfaces ready for prime-time

[Tony Maro]

I just want to confirm my findings and those from the IRC room.

>From the looks of it, the only interfaces that are really working right
now are Win32 and GTK1. 

I played with the QT interface but it constantly crashed with anything
more intense than a label and a button.  The GTK2 interface has serious
drawing issues which makes all components bleed through or draw in the
wrong z-order, and if you ever specify a custom font or try to draw
fonts directly on a canvas they show up in something like a 100 point
font or larger.

I'm mostly interested in seeing GTK2 become usable.  I've looked through
the code and to be honest, it's all greek to me.  I dug through it for
around 4 hours yesterday and left knowing less about the interfaces than
I started with I think ;-)

I understand the GTK2 code is kind of a mess because of the way it was
branched off the GTK1 stuff.  Is there anyone currently working on this
code?

I set it in the compiler options to add content for gdb debugging - and
I'm not doing the debugging inside the IDE but by running gdb at the
command prompt.

It's like something in FPC or Laz is detecting the crash and handling it
before it hits gdb.

[lazarus] How to debug?

[Tony Maro]

Okay I've never had this problem before.  I just built a new machine and
installed yesterday's snapshot of Lazarus and the stable FPC (2.0.2? 
Linux.)

When I run either Lazarus or an app I build with Lazarus under gdb, and
there's a crash, gdb does not immediately pause things and let me look
at it.  The project throws it's own dialog or completely closes and gdb
says it closed normally.  It also says there's no stack.

Did I miss a checkbox somewhere?

Then maybe I could figure out why Lazarus dies when built with GTK 2
complaining of invalid floating point operation...

Log into the wiki, then directly change the URL to have the pagename you
want to use.  For instance, if your topic is "Test Blank" do:

http://wiki.lazarus.freepascal.org/index.php/TestBlank

You'll get a page saying there's no text yet, then you just edit it.

You guys do know I've already put out the framework for an installer
that's mostly compatible with InnoSetup?  I concentrated on the Linux
side of things for it, so there's no registry support yet... but it
wouldn't take too much to add it.

And it's got a nice GUI that beats InnoSetup.  It's what I used to
package the Linux installs for TruckBytes.  It even optionally
compresses files as it adds them into the executable package, and can
launch a readme afterwards or the installed app if you choose.

I stopped once it suited my needs, but with a bit more work it could be
very feature-rich.

Instead, load the extractor into a TMemoryStream, attach streams of the
resources to the end of it, then add pointers to the end of that to the
start location of each resource.   Have the main extractor read itself
into a filestream, get the pointers for each individual resource, and
extract them back out.

Pretty simple actually, and appending to the end of the main file
doesn't break the executable.

[lazarus] Updated daemon instructions?

[Tony Maro]

I'm trying to implement a deamon using and example I found at:
ftp://ftp.cncware.com/pub/fpc/daemon.pp

I've of course had to make several changes to support a more recent
compiler.

Everything compiles fine, and the process forks and dumps directly to
the console as expected.

However, it's not letting everything go... when I log out of ssh after
running it, the session still hangs.  I can't launch the daemon from a
PHP script (which was the plan) because it causes the apache routine
running it to hang.

Probably more of an FPC question I guess, but I trust you guys.  ;-)

Any ideas?

Actually I get support request e-mails all the time on my software
written with Lazarus from people who don't have GTK+ installed.  I also
get a lot of questions because several GTK+ installs don't install all
the required pixbuf libraries.

I'll double-check when I get home - it's at home I'm at work.  But it

if it continues tonight I'll run some test to see if I can find out why.

Actually, I look at neither.  I typically stare off in space or at

Hehe, right now I'd be happy just having the darn warning disabled with
a check box!  I invariably click in the source, then try to start typing
in the code without looking at the screen and the dialog has popped up. 
3 lines of source later I look over and realize nothing I typed went in
the editor.

 At the moment the IDE does this:
 On saving/opening a file it retrieves the FileAge of the file.
 At several occassions it compares these file dates with the current file

 If it changed it gives the user the choice.

I just double-checked and the clocks on the two machines are in perfect
sync... while watching both clocks they appear to change seconds at
exactly the same moment.  Of course this could mean it's a few
milliseconds off, but that shouldn't trigger it should it?

I never had this problem when using SMB to access the same files, so,
perhaps it's something else triggering this?  It's the same two
machines, but now I'm using NFS instead of SMB.

It's odd, because both computers sync clocks from the same timeserver -
which is also located on my network.  I've looked and the clocks appear
the same, so I assume it's something about going from Linux to Windows
over NFS that's making it look different.

I'd think have it run the DIFF before deciding to pop up the dialog, and
if nothing appears, ignore the change?

[lazarus] Changes to file on disk warning annoying

[Tony Maro]

I just changed from using SMB to get to my source files to using NFS to
a Windows box.

Now Lazarus complains around once a minute that the file has changed on
disk, and offers to reload the changes - looking at the DIFF provided,
there _are_ no changes.  I'm assuming it's an NFS or timeclock related
thing.

Is there a way to disable this check in the Lazarus IDE?  I checked the
options but couldn't find anything.

Or you can use the lazy man's method.

Include "unix" in the uses clause, then do:

 shell('ls "/my directory/" > "/destination/lists.txt"');

It won't work in Windows though, and isn't as safe as using a TProcess.  
If the shell command doesn't immediately return from executing, it will 
appear to lock up your application.  Also, note the single quotes around 
the total command line, and the double-quotes within the command line to 
handle spaces within the paths.


For Windows, the shortcut is:

include "windows" in the uses clause then do:

shellexecute(0, 'open', pchar('dir "c:\my directory" > 
"c:\destination\lists.txt"'), nil, nil, SW_SHOWNORMAL);


I just give these as examples.  I recommend the TProcess method, because 
it's cross-platform and has more checks and balances built in.  But, I 
admit that when I'm spitting out a quick program just for myself, I'm 
more likely to use "shell()"

Re: [lazarus] Some questions about TForm.Height

[Tony Maro]

Alex Smirnov wrote:


*Dear Friends!*

Ones more I ask you for some help. Help me please to understand how 
can I get real height of any form window created by Lazarus? The 
matter is trhat TForm.Height returns not a total Form height, but Form 
height minus title bar height. Actually, in Lazarus TForm.Height is 
equal to TForm.ClientHeight in Delphi.


So, ones more - I can't find any info about that. This problem is very 
important for me.


*Best regards, Alexey.*


In Linux (and OSX?) the window manager is a separate thing, and 
interchangable, so the only metric we can reliably get is the clientheight.


I'm not sure what happens in Winblows.

Yes.
But in the case, that the class declaration and the methods bodies contains
exactly one method that does not fit, then it's pretty obvious, that these
correspond.
 

Ah, I see what you mean - one declaration, but two method 
implementations.  Yes, that should be easy to detect I'd think, and only 
create it as overloaded with class completion if there are two methods, 
otherwise fix the implementation.

Hi all,

When I have the following code:

After invoking code completion the skeleton of procedure TFoo.FooProc is
created. Then I change the definition to read as follows: 


type
 TFoo = class
   procedure FooProc(AValue: TWhatever);
 end;

Pressing C (thus invoking code completion) a new skeleton
for procedure TFoo.FooProc is made. I think this is not the correct
behaviour. Either it should do nothing at all, or it should adapt the
previously created version.
Any opinions on that?
   



I would prefer automatic adapting too.
But some Delphians would expect something different:

I was wondering what is the best way of doing translations in user

Lazarus has an interesting method for working with .po files directly
but it is licensed GPL wich means it can be used with GPL only
projects, should one write it's own unit that does a similar job or
will it be included in LCL ?

Using PO files is GPL only?  That's news to me... can someone else 
confirm this?  I thought it was just a method of replacing strings...

Re: [lazarus] Starting lazarus from explorer does not work

Hallo,
 
I have a problem I can't understand: I did an update of Lazarus 
yesterday and recompiled it. Now when I start Lazarus from the command 
prompt, it works fine, but if I start Lazarus from the shortcut I have 
for it, or from Windows Explorer, it is giving problems. It almost 
looks like it has something wrong in the directory it uses.
When I start Lazarus I first get a message that says my free pascal 
source directory is not set up. It is set up and works fine if I start 
from command prompt. So I ignore it.
Then I get an error saying: The current Lazarus directory 
"C:\mysvn\lazarus\lazarus.exe\" does not look correct. Indeed, it is 
not correct! Where does this directory come from? So I ignore that as 
well.
Then I get an error saying that Lazarus is "Unable to create file 
"C:\mysvn\lazarus\lazarus.exe\compilertest.pas". If I choose ok to go 
on anyways lazarus crashes.
 
It appears there is some difference between starting from explorer and 
starting from the command prompt that gives a problem only since the 
last svn update.
 


Sounds like somebody added a writeln and/or disabled -WG?

That and more ;-)

I found that I got about 85% widget usability from my app after 
recompiling for GTK2 - not bad when you think about the task required 
for creating the GTK2 interface.  I haven't tested GTK2 in almost two 
months though...




My application works normally on GTK2, including the database. 


Yeah, most of the issues I've seen are with the more extravagent widgets 
displaying wrong or handling messages wrong.  Internal code like 
TDataset are unaffected.  Once it's polished off, I plan to switch to 
GTK2 and Win32 development exclusively.

Re: [lazarus] TXMLConfig from FPC and Lazarus

Hi,

I see that there is two TXMLConfig, from FPC and from Lazarus, but

My problem is that: compliler link with TXMLConfig from FPC and
parameters for constructor aren't valid.

I use in some package
MyConfig := TXMLConfig.Create('setting.xml');

but constructor from FPC\FCL\xml\xmlcfg.pp are
constructor Create(AOwner: TComponent); override;

How I can force use TXMLConfig.Create('setting.xml')?
Or How I must rewrite my code?


 

To answer the first question, use the unit name in front of the 
component name.

[lazarus] TZLibReadArchive issue... Attn: Andrew H

[Tony Maro]

Follow my steps here and see if I'm on track...


I have a TMemoryStream.
I pass it to TZLibReadArchive.Create()
When TZLibReadArchive is destroyed, it destroys my memorystream, instead 
of a copy of it or leaving it intact.


I'd think if I create a memory stream myself, then pass it to 
TZlibReadArchive, it shouldn't be freeing my object.

As far as I can see libglib2.0-dev is in the standard Ubuntu repository, you 
should be able to just 'apt-get install' it or you can use synaptic.
 

My understanding is that Ubuntu is basically a prettied-up Debian, so 
you sould be able to find any packages you need.

Documentation in Linux often assumes that the programs will be

Maybe this is my Windows background, but I find that they should have 
specified in the documentation what datadir and sysconfdir are. I find 
it often better to explain things in documentations as if one does not 
know anything.


Actually the docs say they are listed in /etc/xdg/[something] and if not 
present there's a default path to use.  I don't think the configdir I

root... which I'd like to do.  Also, where the heck is "datadir" and

(not listed by "env" anyway) that describe these. 


GetEnvironmentVariable('XDG_CONFIG_DIRS') returns a blank string...
