Hi,
Just checked, on WM_PAINT all event listeners (event paint) are
called.
Overwriting onPaint seems to work better (issue 18 in dgui
bitbucket site). Please file this issue also on the dgui bibucket
home page.
Kind regards
Andre

Hi.
I've created a graphic button as per this example on the dgui
website:
import dgui.all;
class MyForm: Form
{
this()
{
text = "An Exception was thrown...";
size = Size(130, 100);
// Or use `Bitmap.fromFile`:
auto img = new Bitmap(90, 15, SystemColors.yellow);
auto pen = SystemPens.blackPen;
with(new Button())
{
bounds = Rect(10, 10, 100, 25);
parent = this;
paint.attach((s, e)
{
e.canvas.drawImage(img, 5, 5);
e.canvas.drawLine(pen, 5, 10, 95, 10);
e.canvas.drawLine(pen, 10, 5, 10, 20);
});
}
}
}
int main()
{
return Application.run(new MyForm());
}
and added a writeln("paint") in the paint.attach to show when
the button is repainting. When the form with the button is
visible the button is being continually repainted. Is this a
'feature' of dgui or is there a flag to set to only re-paint
when the button is invalidated?
