[lazarus] SVN Update: ChildSizing
The following properties now work: TWinControl.ChildSizing. Layout, ControlsPerLine, EnlargeHorizontal, EnlargeVertical, ShrinkHorizontal, ShrinkVertical With these properties a TWinControl can automatically position its childs in rows and/or columns. An example are TRadioGroup and TCheckGroup, which layout code has been removed and instead use the new properties.Advantage: TRadioGroup columns can now have different sizes. I also added the new property TCheckGroup.AutoFill. Mattias _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Can you create a patch?

Re: [lazarus] Turbopower IPro problem - selecting text in HtmlPanel
I managed to display selected text as inverted by replacing
// in ipHtml file, "procedure PaintSelection;".
{$IFDEF IP_LAZARUS}
writeln('TIpHtml.PaintSelection PatBlt not implemented');
{$ELSE}
with code that follows:
{$IFDEF IP_LAZARUS}
BitMapToInvert := TBitMap.Create;
BitMapToInvert.Width := R.Right - R.Left;
BitMapToInvert.Height := R.Bottom - R.Top;
BitMapToInvert.Canvas.CopyMode := cmMergePaint;
BitMapToInvert.Canvas.CopyRect( Rect( 0, 0, BitMapToInvert.Width,
BitMapToInvert.Height ),
PaintBuffer,
R );
PaintBuffer.CopyRect( R,
BitMapToInvert.Canvas,
Rect( 0, 0, BitMapToInvert.Width,
BitMapToInvert.Height ) );
BitMapToInvert.Free;
{$ELSE}
You have first to declare a TBitMap named BitMapToInvert at .PaintSelection
var declarations:
BitMapToInvert: TBitMap;
It is flickering but works fine inverting colors correctly.
What I'm still investigating is to make SelectAll method to work.
Any ideas are welcomed.

I was reading Christian U. message at
http://www.mail-archive.com/lazarus miraclec.com/msg01959.html and
would
like to know the progress of using Turbopower Ipro to read HTML files.
I could load a HTML into the HTML Panel, but got errors when tried to
select a bit of text
IpHtml.pas about line 7827 I've got
{$IFDEF IP_LAZARUS}
writeln('TIpHtml.PaintSelection PatBlt not implemented');
{$ELSE}
As for loading text into HtmlPanel, this is what I did:
procedure TForm1.Button1Click(Sender: TObject);
var
h: TIpHTML;
f: TFileStream;
begin
h := TIpHTML.Create;
f := TFileStream.Create('d:\my.html', 0);
h.LoadFromStream(f);
IpHTMLPanel1.SetHtml(h);
end;
How can I copy-paste text from Ipro HtmlPanel to other applications now?

Is space for the icon allocated in the tray - i.e. is there a "hole" ? - and it just doesnt draw or doesn't "anything" happen? In your version, check the value of fWindow and use "xwininfo -id x" to see if it's correct... Most of those kind of problems with lowlevel X stuff not getting executed properly have to do with the widget not being realized yet...

The company is called Master Maths, based in South Africa. We develop software for math education. Used in schools, centres, universities and government institutes. Master Maths have 100+ franchises in South Africa, UK and some other countries in Africa. The product consists of a Admin program that does the normal data collection, reporting and accounting aspects. The other part is what we call the Browser. It views the encrypted Macromedia Flash content inside the application, and handles tests, etc. The content is huge - 15 CD' s for the complete system. They also have a separate product called Distance Learning, where you can buy a single Grade at a time. The current system is developed for Windows only, using Delphi and VB. We are now busy with Ver.3 which is a total rewrite using Lazarus, so we can make the product cross platform (Windows and Linux).
