UnDelphiX: Filling DXImageList at runtime

[bjrtap]

Hello,

does anybody konw how to fill the DXImageList on runtime?
I was possible to load pictures at the Form.OnCreate event,
but not later. Any ideas?

[cairnswm]

I use normal delphiX and use the DXG lists. These load fine during runtime. using a standard DXImageList.LoadfromFile call.

I have not tried loading single Images at run time.

but creating this DXG file is kinda difficult, isn't it?

To load an individual image at runtime, you can use something like this:
[pascal]
var
DIB: TDIB;
Item: TPictureCollectionItem;
fs: TFileStream;
...
Item := TPictureCollectionItem.Create(DXImageList.Items);
with Item do begin
PatternWidth := 64;
PatternHeight := 32;
SkipWidth := 0;
SkipHeight := 0;
SystemMemory := False;
Transparent := True;
TransparentColor := clFuschia;

DIB := TDIB.Create;
fs := TFileStream.Create('image.bmp');

DIB.LoadFromStream(fs);
Picture.Assign(DIB);
Restore;

fs.Free;
DIB.Free;
end;[/pascal]
That may not be the bast way to do it, though. You could load the patternwidth, etc. values from the stream as well.

To create a DXG file, you can use one of the utillities listed here, such as DXG Edit. This file can be loaded using DXImageList.LoadFromFile as cairnswm says. Note that loading a DXG file will clear any images already in the list.
