[Lazarus] Printing in Linux
Hi. I'am working on multiplatform Win/Lin app whose main job is graphics printing. In Windows all works ok, but in Linux output postscript is wrong. After little digging I found that TPoscriptCanvas is responsible for it. I have a question about Lazarus future plans in rendering graphics output to postscript. Shouldn't be better to use for example Cairo than make poscript output yourself? Petr -- Petr Kristan .

[Lazarus] Having trouble getting fptimer to work in a Daemon.
Hi, I'm a pascal newbie, after spending some time getting a daemon to work, I now have trouble getting a timer to work. I was recommended to use TFPTimer from the fpTimer unit - http://mantis.freepascal.org/view.php?id=14118nbn=5 I tried the following code but the OnTimer doesn't trigger. There are no errors either.

[Lazarus] xml reading problem
dear all,
I have some problems reading xml files.
If I read xml files using ReadXMLFile it works only if I use:
1. procedure ReadXMLFile(out ADoc: TXMLDocument; const AFilename:
String); overload;
while if I use
2. procedure ReadXMLFile(out ADoc: TXMLDocument; var f: Text); overload;
the program crashes.
I attached two files (acetyl.cml and acetyl2.cml). The second one is
always read properly, the first one is read properly only if I use
procedure 1.
In order to reproduce the error just create a new project, put a button
and two tedit on the form.
In the button1 click put this code:
procedure TForm1.Button1Click(Sender: TObject);
var
F: TextFile;
FileName: String;
XMLMolDoc: TXMLDocument;
XMLMols: TDOMNodeList;
begin
FileName:= Edit1.Text;
//AssignFile(F, FileName);
//Reset(F);
//ReadXMLFile(XMLMolDoc, F);
ReadXMLFile(XMLMolDoc, FileName);
XMLMols:= XMLMolDoc.GetElementsByTagName('molecule');
edit2.text:= IntToStr(XMLMols.Count);
//ClosefILE(F);
end;
With this code it works.
While if I put this:
procedure TForm1.Button1Click(Sender: TObject);
var
F: TextFile;
FileName: String;
XMLMolDoc: TXMLDocument;
XMLMols: TDOMNodeList;
begin
FileName:= Edit1.Text;
AssignFile(F, FileName);
Reset(F);
ReadXMLFile(XMLMolDoc, F);
XMLMols:= XMLMolDoc.GetElementsByTagName('molecule');
edit2.text:= IntToStr(XMLMols.Count);
ClosefILE(F);
end;
It crashes raising: exception class 'EXMLreaderror' with message:
In 'file:///e:/temp/acetyl.cml' (line 1 pos 21): expected ?
Why?

I maybe don`t understand your answer. In Windows is rendering for printer implemented by operating system WinAPI. But in Unix we need to render into postscript. Now it is realised by TPoscriptCanvas which do not use any library, but output is erroneous. As I know, Qt has its own rendering engine (screen and printer). For example Kylix uses it. And I now do not know if in LCL exists TQtCanvas used by LCL-Qt. Cairo library is multiplatform and renders into X11, Win32, PS, PDF, ... It do not depends on gtk. Dependency is reversed -- new Gtk2 uses Cairo to render widgets. For example WebKit and Firefox3 uses this library on all platforms. http://en.wikipedia.org/wiki/Cairo_(graphics) What about to make TCairoCanvas and use it by default in LCL-Gtk2. IMHO generated postscript output should be better then TPoscriptCanvas makes. TCairoCanvas (certainly with corresponding library) can be useful in other platforms.

Yes, but it adds an external dependency which would need to be deployed with software that uses it, and Lazarus cannot impose such restriction in everyone that uses it. That's why it would only be used in LCL-Gtk2, as it already depends on Cairo What about to make TCairoCanvas and use it by default in LCL-Gtk2. IMHO generated postscript output should be better then TPoscriptCanvas makes. We still need to hear other developers, but sure, I guess if you implement a TCairoCanvas and contribute it, and it works better then the current method, then it will be added and used for LCL-Gtk2. We can keep the current postscript canvas for other UNIXes, even if after that a Qt-specific method is added, because then it can be used for other UNIX widgetsets that may be added one day (fpgui, for example) thanks, -- Felipe Monteiro de Carvalho -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] How to use ExceptProc and application.CaptureExceptions
Hello,
I'm trying to turn off application exception capturing (so I can send
exception traces via HTTP in bug reports):
1) In (the first loaded unit of) a console app, I did override
ExceptProc (see code at bottom) - my own handler is called (as expected)
on a EDivByZero exception.
2) In my Lazarus LCL app (SVN 23483M, LCL/Win32/i386, fpc 2.4.0), I did
the same like in the console app - additionally, I did set
Application.CaptureExceptions to 'false':
Application.Initialize;
Application.CreateForm(TForm1, Form1);
application.CaptureExceptions:=false;
Application.Run;
Now, when a EDivByZero is raised, my own handler is *not* called -
instead the default TApplication.HandleException is called - To my
surprise...
a) When raised before Application.Run, my own handler is called (as it
should).
b) When I debug Application.Run, it correctly uses the case without
exception handling(!) - that is, it correctly detects the
CaptureExceptions change.
c) When I read ExceptProc right before the exception, it correctly has
the value of my own handler(!)
Though, my own handler is never called within Application.Run - and I
have no idea why...
Any help or ideas are welcome!
Thanks,
Alexander

If I run the strip-all command I get: Object table: # Name VirtSizeRVA PhysSize Phys off Flags -- 01 .text 00116B90 1000 00116C00 0400 6020 [CER] 02 .data 0004B8D8 00118000 0004BA00 00117000 C040 [IRW] 03 .bss 7054 00164000 C080 [URW] 04 .idata2A08 0016C000 2C00 00162A00 C040 [IRW] 05 .rsrc 1F78 0016F000 2000 00165600 5040 [ISR] 06 /400304232 00171000 00304400 00167600 C020 [CRW] 07 /16 0021E233 00476000 0021E400 0046BA00 C020 [CRW] 08 /30 0005A3B4 00695000 0005A400 00689E00 C020 [CRW] 09 /42 0002CDBC 006F 0002CE00 006E4200 C020 [CRW] And sections starting with / are not being removed and the exe size is around 7 MB. Now unchecking the -g and -gl flags I get: Object table: # Name VirtSizeRVA PhysSize Phys off Flags -- 01 .text 001153B0 1000 001153B0 0400 60500020 [CER] 02 .data 0004B848 00117000 0004B848 00115800 C0500040 [IRW] 03 .bss 5404 00163000 C0500080 [URW] 04 .idata29F0 00169000 29F0 00161200 C0300040 [IRW] 05 .rsrc 1F78 0016C000 1F78 00163C00 C0500040 [IRW] Which is the expected result and exe size around 1.7 MB. I had tried to issue a: strip program.exe --remove-section=/4 without success. Does this means that the strip is not usable anymore or that sections should not be there or have different flags ? I'm using fpc SVN, Lazarus SVN and WinXP SP3.

Re: [Lazarus] Printing in Linux
Shouldn't be better to use for example Cairo than make poscript output yourself? It has pros and cons, on the nice side a very big amount of programming would be reused which means a better quality on output but it does impose a library dependency on application. I don't see that as a impossible obstacle though, on windows application deployment may include needed libraries (problems that comes with this approach are beyond of this topic) and on Linux needed libraries are usually already installed. The printing package is implemented by operating system rather then by widgetset, so if you use Cairo it would only work with LCL-Gtk2 and a new code would need to be written for LCL-Qt. I maybe don`t understand your answer. In Windows is rendering for printer implemented by operating system WinAPI. But in Unix we need to render into postscript. Now it is realised by TPoscriptCanvas which do not use any library, but output is erroneous. It may be independent of GTK2. As I know, Qt has its own rendering engine (screen and printer). For example Kylix uses it. And I now do not know if in LCL exists TQtCanvas used by LCL-Qt. Printer support is already implemented for Qt, and if we want to support GTK native printer dialogs we need to implement a cairo canvas anyway. Cairo library is multiplatform and renders into X11, Win32, PS, PDF, ... It do not depends on gtk. Dependency is reversed -- new Gtk2 uses Cairo to render widgets. For example WebKit and Firefox3 uses this library on all platforms. http://en.wikipedia.org/wiki/Cairo_(graphics) What about to make TCairoCanvas and use it by default in LCL-Gtk2. IMHO generated postscript output should be better then TPoscriptCanvas makes. I been playing with this for long time, but every time there is something more to do, of course a patch would be welcome. TCairoCanvas (certainly with corresponding library) can be useful in other platforms. Rendering into PDF, SVG or PNG may be convenience to anybody. Petr -- Petr Kristan Jesus Reyes A.

[Lazarus] Hiding Comments
I know this is probably hard to implement but I sometimes would really like to have it. ;-) I have some heavily commented code, be it for the following reasons. - Comments explaining what the following code is doing, sometimes line by line. - Comments which keep some thoughts of previous implementations in code (not for shipping) but which might be helpful and be it only for not going that route again. - Some todo stuff (I know about the todo feature). I think it would be helpful to hide all comments at times, because while helpful, they make reading the actually working code a lot harder. Does anybody know if this is implemented somewhere in other IDEs? Does anybody else think this would be a good feature? Does anybody have a suggestion how to implement this? Don't beat me, it's just a question and I have no answer. ;-) Thanks -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] Hiding Comments
Hello all, I join theo in asking for such features, my emphasis is on having more structured comments embedded in the code. For example, storing the design model, requirements, or traceability to the design and requirements. Of course, this would be awkward to manage if a feature like the one theo asks is not available. Even better, if there were a system to manage the structure of the comments (and turn them on/off), maybe in some XML-like syntax... For example, I would love to be able to mention the Big-O notation of the algorithms in a structured manner that can be recovered automatically, and can be optionally hidden in the code when not useful.

Re: [Lazarus] Hiding Comments
Hello Theo,
I think it would be helpful to hide all comments at times, because while
helpful, they make reading the actually working code a lot harder.
That's why I prefer external documentation like is done with FPC and
Lazarus projects - using XML files.
Alternatively, keep most of your comments above the
method/function/procedure. If you want to hide them automatically, simply
wrap them with {%region} so it enables code-folding.
eg:
{%region 'comments hidden by default' -fold}
{ This is my very long comment that goes on for many lines...}
{%endregion}
procedure MyProc;
begin
...
end;
The '-fold' in the %region line will tell the IDE to code-fold than region
by default. I use this for all code auto-generated and managed by fpGUI's
UI Designer.
The last solution is to simply not comment your code! Make it the next
developers problem. :-)
Regards,
- Graeme -

Change your editor preferences and change the foreground and background color for comments to be the same as the editor background. All comments are now invisible. ;-) Regards, - Graeme - -- fpGUI Toolkit - a cross-platform GUI toolkit using Free Pascal http://opensoft.homeip.net/fpgui/ -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
