The -n tells it to not use the regular cfg paths, and what follows
tells it where to find the cfg file to use.


i don't know if this ties in or not but your make line appears to be missing a 
space between the closing double-quote and the '-n'... was this simply a typo in 
the message or is it really like that when your tool generates that call? if it 
is not a typo, then it is possible that the passing on of the param doesn't 
succeed because of the missing space and so the '-n' is not detected and 
available to pass on...

Definetely.
What you're missing is that Component* properties refer to
owner(ship). You should use ControlCount and Controls properties
instead.

The panel is the parent. I wrote the following code:
  ShowMessage('btnReloadQuotes.parent: ' + btnReloadQuotes.Parent.Name);

it does claim that the parent is the panel.

Yes, that's shows exact problem  that's because dx isn't implemented in

There is some problem with some combinations, probably submenus + checboxes.
I'll create pure C++ app to see if it's really Qt problem, or something else 
in qtlcl (but I doubt about it) - flickering probably happens because 
QCheckBox sends some activation events or similar.

That's something that I don't know. First: I must understand what's exact

No, I don't see such issues at all (Fedora 14 32bit, Lazarus 1.1 svn 20-30

I believe these to be regression errors then. I have experienced both of 
those before, but can't remember if it was with LCL-Qt or LCL-GTK2. I 
was fixed, but this was long before v1.0. I now only use LCL-GTK2, and 
can't see that issue now.

[Lazarus] building lazarus 1.0 with make OPT="-n" and fpc.cfg in different location

[Seth Grover]

Greetings. First off, congratulations on the 1.0 release. Lazarus is a
terrific IDE and a great development platform.

I've got a script that I use to build FPC/Lazarus from source and roll
it into my own custom package. During the build of Lazarus,
/etc/fpc.cfg doesn't exist yet. This isn't a problem for the most
part, because I used samplecfg to generate an fpc.cfg file in a
temporary location. Then, when building Lazarus, I do it like this:

make bigide PP=/path/to/wherever/ppcx64 OPT="-n @/path/to/tmp/fpc.cfg"

The -n tells it to not use the regular cfg paths, and what follows
tells it where to find the cfg file to use.

This works fine for most of the build: lazarus builds and links, as
does startlazarus and some of the other binaries. However, when it
gets to building the "lhelp" binary under chmhelp, I can see my OPTs
aren't being passed down, and it fails with an error that /etc/fpc.cfg
doesn't exist.

I've worked around it by symlinking /etc/fpc.cfg to my temporary file,
but it would be better if it worked correctly.

Thanks,

[Lazarus] issues with Lazarus Qt

[ik]

Hello,

I'ved recently tried to use Lazarus 1.1 with Qt version.
While it looks native and really cool in my KDE, I had few issues with it:
1. Font rendering with TSynEdit - It had a lot of issues to display
the end of a char at the end of a "word" that after it there was
space, dot etc ...
2. The selecting of text in SynEdit, changes the length of the font.
So the text moving.
3. The Messeges window keep on disparaging
4. The menus are flickering, and even changing the focus of other windows
5. In the editor, CTRL+SHIFT+Space hint, go over the completion option

Before I'll start to report these as bugs, are these known issues ?

I'm using Arch Linux 64 bit with KDE 4.9.00 with Qt 4.8.2, FPC 2.6.0

Ido

I doubt it.

RTTI may (you need to establish if this applies to *all* cases) tell you
that "procedure Foo(a: integer)" takes 1 int param.
But it will not tell you, if this needs to be on the stack, or in a
register (or which register).



Sorry, not correct. It does: in calling convention.

The point I meant to made is: you still need to get the value into that
register, or set up the stack. That can only be done in asm


Yes, it can only be done in ASM, but the Invoke function is part of the 
RTL and thus would by definition be available for all platforms 
supported by FPC (even if not every platform would be available at once).

Sven

No, you don't need to do anything.  Invoke calls the function with the
supplied "Args", which is exactly what the assembler code in
pascalscript does.

Depends on your application. Here it works for shaped TButton (shape is setted

I have heard that. And I (partly / see below) accept that. But:
1)
Would a single quoted line (such as the one I quoted here), *if* it was

Isn't that more about proper quoting? And top posting (in my experience) 
is 99% done with quoting all. Which means you still have to listen to 
the entire quote, since in addition to the top post there may be more reply.

2)
Should that not be fixed by the screen reader. Should the screen reader 
not have an option to skip the quotes?
If my mobile only supports about 30 chars per line, do I  asked everyone 
to shortens the lines, when they send? No! I expect my mobile to word 
wrap or scroll.

Aha, might be, but it doesn't matter. You can use OnShow then.

In Gtk2 OnShow also doesn't work.

I don't know for gtk2 atm, but eg. under Qt QPainter have opacity property 
which does thing you want. Maybe it's possible under gtk2 (by using cairo) to 
do same thing.

[Lazarus] PascalScript on Win x64

[Alexander Hofmann]

Hi there.

This is a cross-post (cross-mail ?) to
http://www.lazarus.freepascal.org/index.php/topic,17978.0.html as I got
the hint there that it might be better to ask on the list instead of in
the forum, at least concerning the calling conventions - but I'll ask
the whole lot, anyway; I hope that's ok.

Has anyone successfully used PascalScript with Lazarus Classes (e.g.
TForm, TButton) on Win x64?

I can compile the downloadable latest stable version from RemObject's
website (the one with the EXE-Installer) as well as the latest
development version from https://github.com/remobjects/pascalscript OR
(that's not in the Forum) the PascalScript-version included in Lazarus'
SVN, no Problem there, after two small changes in x64.inc (see below).
Running the script works, adding user defined functions (and calling
them!) is OK, too.

But as soon as I try to Create forms and objects, like the following
script, the Program crashes with a SIGSEGV.

|program Script;

var
  f:TForm;
  b:TButton;
begin
  f:=TForm.CreateNew(nil); //<- Works
  b:=TButton.Create(f); //<- crash
  b.Parent:=f;
  f.Show;
end.|


Crash in the Program is here:

|CLASSES_TCOMPONENT_$__INSERTCOMPONENT$TCOMPONENT 
0044F900 4883ec38 sub$0x38,%rsp
0044F904 48895c2420   mov%rbx,0x20(%rsp)
0044F909 4889742428   mov%rsi,0x28(%rsp)
0044F90E 4889cb   mov%rcx,%rbx
0044F911 4889d6   mov%rdx,%rsi
0044F914 4889da   mov%rbx,%rdx
0044F917 4889f1   mov%rsi,%rcx
0044F91A 4889f0   mov%rsi,%rax
0044F91D 488b00   mov(%rax),%rax
0044F920 ff906801 callq  *0x168(%rax)  <-- crash| 


Am I doing anything wrong? The same Script runs fine when the
Application was compiled with x86 Lazarus 1.0.
By the way: creating a TObject with e.g. o:=TObject.Create doesn't break
at al.

Interestingly, when I start debugging
.Create(aOwner:TComponent)-Type of Constructors, there is
some difference in the Register values, depending on whether the
Constructor was called from "pure" FPC-Code or the Script (at least so
it seems):
o Called from FPC: rcx: 0 (nil), rdx: Class Reference, r8: Value of aOwner
o Called from Script: rcx: Class Reference, rdx: 1 (!?), r8: Value of
aOwner (at least so it seems)

Is there any difference in the calling convention on x64-Systems between
Delphi and Lazarus? I could only find the "standard" information on
Windows x64 calling conventions, without special care of constructors,
if there is any...

Did anybody else stumble about that problem before? Thanks for your help!

fppkg should be supported. There is already an IDE plugin although it
needs some work.
But fppkg is more like a distribution, that means the packages must have
a valid fpmake file and must be uploaded to it. This implies a few
restrictions on the package layout and dependencies.
There are many third party packages that don't fit into that scheme,
but they do have lpk files. aarre can gather information about those lpk
files. With this information we may find a solution.

How about

making use of the already established and well known acronyms CCR and
FP and FPC and then somehow merging it all into one repository with

Aarre has the benefit of being distinctive. If an English word is

Thanks, I have already created a google code repo for it. I'm cleaning up
the demo app and adding some instructions to the code. Probably today I'll
upload the code and publish the link.
It really is Oauth2 according to Google and the re-usability for other
Oauth2 protocols is limited to picking up some ideas and very little code.
The bulk of the code is calendar api related and class hierarchy from/to
json streaming using rtti (which can be re-used in other apps). It also
includes a tool to assist in the creation of class definitions starting from
the Google specs (json resource representation). So very little in common
with fpctwit/plurk.


I have been looking for this for ages, this is almost a dream come true.
Now I can throw away my own code.  :-)

Where did you find the google specs in machine-usable form ?
Did you try other than calendar APIs with your tool to assist in creation of
class definitions ? I am particularly interested in user provisioning.

Starting simple, finding out what works, and only then increasing scope
is a concept that has worked well for me at least ;) Much better than
writing up all possible use cases and getting lost in functionality that
1% of the users will ever want.
If linked packages doesn't fit into the current ideas, no problem ;) If
it turns out to be something that is desired later on, perhaps it can be
added without too much trouble.

If you support voting as well as provide some indication of where the
package comes from (i.e. the main repo or a linked repo maintained by
somebody else), I think having links is very valuable.
Your idea of having a stable version of a package in the main Lazarus
repo would solve reliability/availability issues, while external devs
could ask their advanced users/people depending on newly released fixes
to use linked packages...

I think the big advantage of linked packages is that it much easier for
devs to provide support for this - they presumably have to fill out some
description file, zip/compress their package and provide a download link
with the result... Not much hassle and no need to contact those poor,
overworked, central repository guys ;)
While the stability etc of this link cannot be guaranteed, as you see,
it is still much better than the current situation: a user has to search
through the wiki, and perhaps forum, to find where to download a
package. At least a (central+linked) package system will be a very good
incentive to provide one big central list of available packages.


> There are many possibilities.
Yep.
I'd also prefer to have something small that just works and that we can
experiment with now, and improve as we go along (as long as we're not
afraid to reorganize things as long as it's in testing mode).

The opinions and ideas are important.
My idea also was to have links to packages maintained elsewhere.
However the stability of the repository would suffer. The linked
servers can have downtimes or can disappear. Copying a stable version
of those packages to the Lazarus repository would solve some
maintenance problems.
Yet, the repository surely needs a maintainer and co-operation with
the package authors.
Does anyone know how Perl (CPAN) and other similar systems do it. I
understand they have have copied the packages and mirror the server.
Some other repositories use links, eg. many Linux distributions.

There are many things involved. Many versions of the same package must
be supported etc.
It can grow into a very complex system which is not the goal now.

The GUI in Lazarus could allow searching and installing, but also
voting for the quality of the packages.
There are many possibilities.

I understand, but the average programmer may not know about the fact
that OAuth2 and 1 are so wildly different... and as you had commit
rights to fpctwit already...

No matter, I'll just add a reference to your page on mine... perhaps
with that new-fangled thing they call a hyperlink ;)

Try e.g. this alternative:

(some more indicated on the page about Lazarus mailing lists)

Presumably using a search engine with something like the term
"lists.lazarus.freepascal.org" will also work well...

Argh. If I read that correctly, having the extension would be useless
because it would put the burden of clearing the cache on the user, who
may very well not even know he should
... so the shell script solution may well be the right one!??! I'd
assume most of our wiki readers are not logged in - only editors have a
reason to create an account - so this is a problem.

Indeed, for users that are not logged in, a file cache is enabled as
described here:
http://www.mediawiki.org/wiki/Manual:File_cache

It seems it doesn't expire the category page.

You can that yourself by adding ?action=purge to the page url. I just
did that and now the page shows with the new tutorials.

Maybe I should install the purge plugin:
http://www.mediawiki.org/wiki/Extension:Purge

What do you think?
