IDE Main Window: height is too small and cannot resize (Linux/GTK2)

Hi,

Just updated Lazarus to r35276 on Linux GTK2 / Fpc 2.6.0.

The IDE's main window (the one with the component palette) now has
lost some pixels in its height (appr. 15), and half of the component
pallette has become invisible.
The main IDE window isn't resizable anymore, only minimize and close
buttons are available.

Anyone else seen this?
Can it be fixed?
(I tried Tools -> Options -> Environment -> Windows, but that will not
let me set position/height for main IDE window).

FWIW:
Linux 2.6.13-15-default #1  GNU/Linux
gtk2-2.8.3-4

fpdoc + XML description file + indentation whitespace

Hi Mattias,

Here is the email I spoke of.. Note that the URL example I listed, is
still affected by the problem as well. The first line with "naAdd" is
correct. All the other "naXXX" line are indented incorrectly due to
the indentation inserted by FPDoc Editor (or by a human).

And as I mentioned, with RTF, IPF, TXT, MAN etc output the problem is
greatly enhanced, because the end result viewers of these formats do
not ignore whitespace.

So bottom line... Indentation in XML is evil.  XML is meant to be
processed by a computer program, not by a human, so indentation really
shouldn't be needed at all.

Hi,

What is supposed to happen with whitespace in the XML Description files.
For example. Say you edit an XML file with your favourite text editor, and
you have a long description. So you add newlines (by pressing ENTER), then
indent the text to the DESCR node for easier human reading. It seems fpdoc
inserts that indented (spacing) whitespace as actual space characters (part
of the help content) in the help content. This is seen all over the place,
but not always noticed in the final output.

Lazarus frozen on F1

Hello,

I have a strange issue. I configured chm help and everything was fine
and nice and then I restarted my IDE and suddenly on pressing F1 my
IDE froze instead of bringing LHelp. And now it always does that even
after I restarted the computer =( The IDE remains frozen in this
syscall:

Add notification to callstack change.

Hi there.

I know very little about notifications, and maybe what i know is wrong, so any help would be useful.

I`m trying to add some kind of notication that triggers an event when the callstack of the application is changed.

By example, the Application.onException is trigged when an exception happens, some event similar to
triggers when the callstack is changed, in other words, when the execution go to the next line of the code.

Please help, any help will be usefull.

semaphores

Hi all.

I need to implement a system wide locking system in all WIn32, Win64, 
Linux32 and Linux64. Therefore I need some king of named locking objects.
For Windows I can use mutexes. For Linex I can only use sem_t structures 
managed by a series of functions in pthrlinux.inc but they are unnamed 
which means that they are only usable inside a multi-treaded process and 
not system wide.
Something else I miss ?

Antonio.

So you can bookmark help topics, search for topics and annotate
existing help? Umm, how did I miss that in Lazarus.

Yes, after all, it is a XML documentation editor.

I can't bookmark a frequently used topic, or add my own personal notes
to that help and see it in the tooltip. As I mentioned before, I
annotate existing documentation a lot. - my personal notes that mean a
lot to me (and probably mean nothing to somebody else, so should
belong in the official docs).

And here we come full circle!  In which format should we document
these features?  XML, IPF, TXT, RTF, ODT, AsciiDoc, DocBook, Wiki
etc....?  And are these features related to the LCL framework, Lazarus

Re: compiling lazarus on arm-linux

Thanks Ludo.

It worked !!

Felipe,  I was right; I was stupid not to test with the latest "fpc"
version (2.6.0) 

(
  Lazarus has been compiled and built successfully.
  However, when I am invoking fpc from command line as

==========================================================
  fpc -S2cgi -O1 -gl -WG -vewnhi -l
-Fu/usr/lib/lazarus/lcl/units/$ARCH-$OS/
-Fu/usr/lib/lazarus/lcl/units/$ARCH-$OS/
-Fu/usr/lib/lazarus/lcl/units/$ARCH-$OS/gtk2/
-Fu/usr/lib/lazarus/packager/units/$ARCH-$OS/ -Fu. -o./magnifier -dLCL
-dLCLgtk2 magnifier.dpr
==========================================================

  I get the error :

  Error: Illegal parameter : -WG

  If you guys know the solution to this on top of your head; please
let me know. Else, I am already looking into the docs 
)

Thanks and Regards,
Ajay

Adding items in a json object and then save to file

Hellow guys, good afternoon. :)

I'm tried to add items in a json object, and I tryied to save it in a
file using stream. My doubt is: do I need to do everything manually?
Or has json a native feature to save it in file? I really could not
find it.

Find attatched a demo application.

Thx.
