No, Yes, Yes.

Currently in the win32 implementation, notebook pages stay the same size.

It must be done, by the interface, because the VCL/LCL has no mechanism to let all childs fill up the client area and overlapp each other.

Hi,

TNotebook pages are implemented as windows with controls on them. Are there provisions for resizing this window when the TNotebook has resized? Does the interface do this in the GTK, or is win32 missing something? Currently in the win32 implementation, notebook pages stay the same size.

Thanks,

Micha.

Yes, no problem under gtk.

If I look at the delphi VCL then it contains the line

Align := alClient;

in TTabSheet.Create constructor. So resizing is done by the pagecontrol itself as if it were a tpanel or tform or whatever. As a side note: if i create two groupboxes on a form, both with align:=alClient, then they are both as big as the client area of the form, thus overlapping.

Regards,

Micha.

Can you explain the differences?

Now to "Align := alClient;": This was not yet possible, because the TPage is a special widget under gtk.

...

I see.

Hmm. I was describing win32-delphi-vcl behaviour (which we are trying to imitate AFAIK), what do you have in mind. Or do you rather want it in a new topic?

Micha.

First of all: TTabSheet TPage.
TTabSheet and TPageControl needs to be implemented. It is very similar to TNoteBook and TPage, so we should try to share as much code as possible.

Now to "Align := alClient;":
This was not yet possible, because the TPage is a special widget under gtk. This widget can not be resized by the LCL. If you set Align:=alClient, the LCl will try to resize it, and the gtk will resize it back - a circle. Because this could happen with other widgets too, this was a general problem. "Was", because it is no more. The LCL now recognizes simple circles.
And so I added the "Align:=alClient" to TPage.

So resizing is done by the pagecontrol itself as if it were a tpanel or tform or whatever.

As a side note: if i create two groupboxes on a form, both with align:=alClient, then they are both as big as the client area of the form, thus overlapping.

This should be discussed separately..

When changing the LCL to let TPage also use Align := alClient instead of SetInitialBounds...I see that height/width is exactly the wrong way around. Page.Width seems to be Notebook.ClientHeight and Page.Height seems to be Notebook.ClientWidth. Can I be certain this is a problem in the win32 interface?
