Re: dgui - Button continually repainting
Hi Andre, I've found a solution to the repainting problem. If you tick the Disable visual themes in the compatibility tab of the program properties (associated with the program icon) the button is only repainted when the mouse cursor enters and exits the button area.

Class core.controls.ownerdrawcontrol.d is very interesting. This event seems more suitable.

dgui - Button continually repainting
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?
Regards, -=mike=-.
Re: dgui - Button continually repainting
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

dgui - self defined components with double buffering
Hi,
I habe several self defined components in my Windows.
During resizing of the Windows, the Windows controls
gets ugly and then disappear. I want to implement
double buffering but found no obvious way to create
a memory canvas and after having done the drawing copying
It to the canvas of the control.
Current implementation looks this:
class TitleBox : PictureBox
{
private Color startColor_ = SystemColors.darkGray;
private Color endColor_ = SystemColors.white;
protected override void onPaint(PaintEventArgs e)
{
Canvas c = e.canvas;
c.fillRectGradient(Rect(nullPoint, this.size),
startColor_, endColor_, GradientFillRectMode.vertical);
c.drawText(text, Rect(Point(2,2), this.size));
super.onPaint(e);
}
}
Does anyone have an idea?
Kind regards
André
DGUI: Using scroll bars
I'm using DGUI (the one on bitbucket) and I can't work out how to use the scrollbars. I've got them enabled but I can't work out from the library files how to set the scale and read the position. Also is there a way of turning off the vertical scrollbar - the 'enable' turns them both on. Any help would be appreciated... regards, -=mike=-
