[Lazarus] TAChart with transparent background
It is not fully clear to me what you mean by "a chart with transparent
background". Do you want to see the form underneath the chart? I fear
this is not easily possible. Or do you want to have a background image
in the chart? For the latter case this code is working fine with me:
type
TForm1 = class(TForm)
Chart1: TChart;
procedure Chart1BeforeDrawBackground(ASender: TChart; ACanvas: TCanvas;
const ARect: TRect; var ADoDefaultDrawing: Boolean);
procedure Chart1BeforeDrawBackWall(ASender: TChart; ACanvas: TCanvas;
const ARect: TRect; var ADoDefaultDrawing: Boolean);
procedure FormCreate(Sender: TObject);
procedure FormDestroy(Sender: TObject);
private
{ private declarations }
FBackImage: TPicture;
public
{ public declarations }
end;
procedure TForm1.Chart1BeforeDrawBackWall(ASender: TChart; ACanvas: TCanvas;
const ARect: TRect; var ADoDefaultDrawing: Boolean);
begin
ADoDefaultDrawing := false;
ACanvas.StretchDraw(ARect, FBackImage.Graphic);
end;
procedure TForm1.Chart1BeforeDrawBackground(ASender: TChart; ACanvas:
TCanvas;
const ARect: TRect; var ADoDefaultDrawing: Boolean);
begin
ACanvas.GradientFill(ARect, clSkyBlue, clWhite, gdVertical);
ADoDefaultDrawing := false;
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
FBackImage := TPicture.Create;
FBackImage.LoadFromFile('C:\lazarus-svn\images\splash_logo.png');
// please adapt this path to your lazarus installation
end;
procedure TForm1.FormDestroy(Sender: TObject);
begin
FBackImage.Free;
end;
The basic idea is to assign a handler to the chart events
OnBeforeDrawBackWall or OnBeforeDrawBackground and disable the default
background painting by setting ADoDefaultDrawing to false. The first
event replaces painting of the area enclosed by the chart's frame ("Back
wall"), the other one replaces painting of the entire chart background.
Above example paints the Lazarus splash-logo as BackWall and a gradient
as background.
Maybe I'll once write a tutorial on this topic...

Re: [Lazarus] Cannot compile EpikTimer
Thanks, this worked. I added unit Linux in here:
{$IFDEF Windows}
Windows, MMSystem,
{$ELSE}
unix, unixutil, baseunix, *Linux*,
{$ENDIF}
Should this be considered a minor bug in epiktimer's platform dependant
code?

[Lazarus] Enabling menu-options depending on a Lazarus-setting?
Hi all, On Linux there's the option to view a window with the console-output of applications being debugged. This option is enabled with the define DBG_ENABLE_TERMINAL in three units. In debugger/debugger.pp the define is set for linux only, with the result that the window is actually visible in the menu. In components/lazdebuggergdbmi/gdbmimiscclasses.pp and components/lazdebuggergdbmi/gdbmimiscclasses.pp the define is also set on linux, so that this debugger actually sends the console output to the screen. Now I have my own debugger, and this debugger also supports the console-window on OS/X.
