I would have some use for it if the ability to specify how many times the 
animation should be played (none, always, 1, 2, etc), be able to specify the 
speed and direction (actually having a ping-pong style animation sequence 
would be nice, like 0-1-2-3-4-3-2-1-repeat, especially for one-time 
animations) and support transparency.

In fact i want to use it as a little animating "warning" icon at the right 
side of some input boxes when the user enters invalid stuff :-).

Mandriva 2008.1 amd64 and Lazarus gtk2

Hello,

I moved this weekend to Mandriva 2008.1 (spring edition), 64 bit.

After I was able to properly compile Lazarus (library dependencies), I
have the following error messages
(The GTK Warning and critical repeates a lot) :

(lazarus:5511): Gdk-WARNING **: The gdk_draw_*_image require the
drawable argument to

however, pixmaps only have colormap by default if they
were created with a non-NULL window argument. Otherwise
a colormap must be set on them with gdk_drawable_set_colormap

The closest component I know of is gamepack, which is overkill for
just animating a bitmap - and also doesn't do the
things Kostas mentioned - since games rarely work like that.

Lazarus on main Mandriva repository

Hello all,

On #mandvia-cooker we discussed about adding Lazarus to the official
repository of Mandriva, and it seems that there are work going to
place it on the cooker repositories.

Just wanted to update.

Problems building Lazarus on Fedora 9

Hi all,

When I try to build a Lazarus rpm for fedora 9 (x86_64) I get the result
below. Could it be that there really is an incompatible glibc?

I like those ideas!  I'll extend the component and create a LCL one as well.

Which fpc version is this?
What abstract method? (Place cursor on class declaration, Source
editor / Popup menu / Refactoring / Show abstract methods)

Re: Printer margins

Ok, thanks, that works nicely, but you have to guess the paper being used.

If we are using a TPrintDialog then the user should be able to select
the target paper and margins in the TPrintDialog.

So maybe some way to get the paper name is missing from TPrintDialog,
or even better, get all margins form there.

Here is my current code:

procedure TfrmPrint.btnPrintClick(Sender: TObject);
var
  PaperWorkRect: TRect;
  PrintDlg: TPrintDialog;
begin
  PrintDlg := TPrintDialog.Create(Self);
  try
    if PrintDlg.Execute then
    begin
      Printer.BeginDoc;
      Printer.papersize.papername := 'A4';
      PaperWorkRect := Printer.PaperSize.PaperRect.WorkRect;
      Printer.Canvas.TextOut(PaperWorkRect.Left, PaperWorkRect.Top, 'TextOut');
      Printer.EndDoc;
    end;
  finally
    PrintDlg.Free;
  end;
end;

Re: Mandriva 2008.1 amd64 and Lazarus gtk2

I don't know how to answer your question, but afaik you can use 32-bit
software in 64-bits systems, so you could try installing the 32-bits
lazarus.
