Hi Bertalan,
make sure that after creating the TGLVContainer you associate
the container with the TGListView. In that case the container
events are properly propagated to the TGListView and things should work.
Example:
fListView = new TGListView(fV2, 520, 250);
fIconBox = new TGLVContainer(fListView->GetViewPort(), 520, 250,
kHorizontalFrame, fgWhitePixel);
fIconBox->Associate(this);
We are well aware of the lacking manual and we will fix this in
the coming months.
Cheers, Fons.
