Hi,

I have tried to draw on the top of a dockwindow
I have something like this.
class main : public DockWindow
{

and
void main::Paint(Draw& w)
{
w.DrawEllipse(dot_x,dot_y,12,12,Black());
DockWindow::Paint(w);

}
but this does not work unless there is empty space between the docked windows..
the size of the Window tends to be zero....if everything is docked.
I would like to draw on the top of them.

Hi,

not exactly sure if that is supported at the moment, BUT the obvious quirk in above code is that DockWindo::Paint overpaints your ellipse. Try to swap those lines.

Hello aftershock,

DockWindow acts as a container. The way to go is adding a ctrl to dockwindow (not as DockableCtrl but using a plain ctrl. E.g. Ctrl::Add(myctrl.SizePos())), and overriding its Paint method. Have you tried that?

Best regards,

No...but I have just done so... Same result..
The window size is the remaining part of the full window where there are no docked windows...

Ok, did you use SizeHint() for dockable windows. You can specify min and max sizes for dockable windows so that they cannot cover the whole area.

And if you can post a basic example (prefeably zipped) I can examine it.

Ok,
Something like this?

index.php?t=getfile&id=5732&private=0

This is a modified version of upp/reference/DockingExample: ( https://www.ultimatepp.org/reference$DockingExample1$en-us.h tml)

Add the below code (no any other alterations needed):

	virtual void Paint(Draw& w)
	{
		DockWindow::Paint(w);
		w.DrawRect(GetSize(), Gray());
		w.DrawImage(GetSize() / 2, CtrlImg::reporticon());

	}

Is this what you need?

Best regards,
Oblivion

This is what happens, yes.. but this is not what I would like to achieve
but I would like to draw on the top of the docked windows as well
your code should grey the whole window....it does not do that.
R sign should dominate the whole window

You just drew on the remaining area as far as I can see,

Can you do it so...that the whole window is treated as one...
E,g, your roman image would appear on the top of roman number table?
