I'm experiencing a problem with frame windows that appears to be inner rect related. When the window is first show, it does not appear to account for the titlebar when calculating the inner rect. If the window is moved and then deactivated the area is closer to correct. Resizing it results in the expected area. Hopefully the following pictures make clear the problem.
First Shown:

Moved:

Resized:

The behavior occurs with both the AquaLook and TaharezLook schemes, so it doesn't seem to be related to the skin being used. I've tried using setArea() and invalidate() on the windows after loading the layout, but that had no effect. Is anyone experiencing a similar problem?

Hi,

I just ran a quick test, but did not reproduce the issue. Can you tell us if you're creating the layout in code or via XML, if via XML can you post the XML (or PM if you don't want to post publicly). Also is the frame window being rendered to a texture target or a normal viewport type target.

Cheers,

CE.

The interface should be rendering to a viewport target (its using the default constructor of CEGUI::OgreRenderer). I think the frame window is rendering to a texture though because AutoRenderingSurface is true for FrameWindow in the looknfeel file. Changing that property had no effect.

The window is from the following layout. We make use of the PropertyCallback to loadWindowLayout, so you might have to comment out a property or two to use the layout. (As an aside, I was impressed by the foresight in that feature

)

Code: Select all

I believe I have figured out how to reproduce the problem. It occurs if the framewindow is never sized while visible. In the layout file above, the framewindow's 'Visible' property is set to false, and the window is shown in response to a key press.

In case it helps, the following snippet after loading a layout causes the window to be drawn as expected...

Code: Select all

const bool wasVisible = window->isVisible();
window->show();
const CEGUI::URect oldArea = window->getArea();
window->setArea(CEGUI::URect(CEGUI::UDim(0, 0), CEGUI::UDim(0, 0), CEGUI::UDim(1, 0), CEGUI::UDim(1, 0)));
window->setArea(oldArea);
window->setVisible(wasVisible);

Hi, thanks for posting the layout and other info; I'll test it out and get back to you about it, though basically it seems that somewhere we're not invalidating the cached area rects when we should be.

We make use of the PropertyCallback to loadWindowLayout ... I was impressed by the foresight in that feature

Thanks, this was put in after a feature request from a user some years back, since then it's proven useful in many scenarios

Ok. This issue is fixed in svn branc v0-7 r2265.

Interesting point here: while for child content the issue only manifests itself in 0.7.0 because of the inner rect / client area fix in that release, the actual bug (checking titlebar visibility instead of the correct option setting) has been present for many years - so nice find

CE.

That was fast, thanks
