There is also the sdl4fp headers http://sdl4fp.sourceforge.net/ which
are h2pas conversions, though I think they may be outdated now.
If you would prefer native lazarus components then gamepack may suit
you. Somebody also had a post here earlier this week about an SDL
framework from XCode - I don't know if that is mac specific or general
though - perhaps somebody could provide a link ?

Re: [fpc] SQLdb: not clear excetion, "Server connect failed."

fpc 2.2.0 sqldb-mysql doesn't work on 64-bit systems. You should use fpc
2.2.1.

freeze while resizing a window (GTK2 with rev 12674)

Hi,

I got a freeze when I resize my window to a size where one of the panels
of the form becames completly hidden (it is moved to the left while
making the window smaller; this is because of the Anchors: left, right,
bottom).

I am using GTK2 and Lazarus rev 12674.

On the console, I get all the time: (also when I do nothing)
[DBGTGT]
NOTE: TGtkWidgetSet.InvalidateRect during paint message: TMainForm

I paused the application after it freezed. This is the stack then:

svn r 12675 fails to compile

When trying to rebuild Lazarus with latest svn (r 12675), compile fails.
In fileprocs.pas it complains that it cannot determine which overloaded 
function to use,  in the DebugLn procedure,  between line vtInt64 and 
vtQWord.
Reverting to r 12674 works fine.

Platform is linux, widgetset gtk1.

Thanks,

Giuliano

It works here with 2.2.1. The change was done for the recent 2.3.1
compiler. What fpc version do you use?

I added a qword overload. Maybe this will run compile under all fpc
versions.

This normally indicates, that you have a bug in your OnPaint code. Only
paint in the OnPaint event. Do not change properties or resize, move,
delete or create controls.

Hiding ancentors member during inheritance

Suppose i've got class
TA = class
public
  itsMember1 : longint;
end;

I want class TB = class(TA); but itsMember1 should be private.
Is it possible?

You're right, I forgot to mention. It's fpc 2.0.4.

I stepped through the code and I figured out that I get the message
exactly at this point:
	GamePanel.Canvas.Draw(0,0,MyRoomPic.Picture);
GamePanel is a TImage and MyRoomPic.Picture is a TBitmap.

So, is the code wrong? How should I draw otherwise the TBitmap on the
TImage?
