GUI redraw after app window size change
Posted: Tue Oct 06, 2009 07:25
Hi there,
I'm using CEGUI with Ogre and just tried to port to the 0.7.0 version of CEGUI. As I have read so far there are some changes to the "'inner rect' fixes made for 0.7.0". As I don't run the SVN version for now, maybe this might be solved when switching to it.
My bigger problem appears when I resize my application window. With the 0.7 version and the new renderer model 2.0 I need to get CEGUI to redraw all windows. The only way I get this done now is by iterating through the window tree and change the size slightly. But this resizing takes about 15 seconds (a complete app hang)...
I have already tried other solutions like:
or
but none of them seems to have an effect.
Can someone tell me what I am doing wrong?
Cheers, Ben
Some more detailed info. This is what Ogre does:
This is how the GUI looks after the first start. The window content is moved from the tilebar and outer window frame. After moving the window once this gets fixed:
This is how the GUI looks after resizing and doing nothing (in fact I have done two mouse clicks to see something at all...):
This is how the GUI looks (and how it finally should look like) after resizing and using the setSize code from above (with 15 seconds delay!):

Code: Select all
void TV3D_GUI::resizeChildWindows( CEGUI::Window* pkWindow )
{
if( pkWindow )
{
CEGUI::UVector2 vec( CEGUI::UDim( 1.0f, 0 ), CEGUI::UDim( 1.0f, 0 ) );
vec = pkWindow->getSize();
vec += CEGUI::UVector2( CEGUI::UDim( 0.0f, 0.0001f ), CEGUI::UDim( 0.0f, 0.0001f ) );
pkWindow->setSize( vec );
for( int nChildIndex = 0; nChildIndex < pkWindow->getChildCount(); nChildIndex++ )
{
resizeChildWindows( pkWindow->getChildAtIdx( nChildIndex ) );
}
}
}I have already tried other solutions like:
Code: Select all
pkWindow->getRenderingSurface()->invalidate(); or
Code: Select all
pkWindow->getGeometryBuffer()->reset();but none of them seems to have an effect.
