I use that in RubberViews, and it works perfectly to resize ContainerControls.
Brilliant! Are you able to access the contents as well?
I don’t modify the content, since RubberViews manages ContainerControl like windows, and scales their content from the inside.
I see. So perhaps this is still of limited use.
It seems quite possible that the limitations in accessing the content be related to the need to properly cast the control. I am not sure which one of ContainerControl or EmbeddedWindow would work.
As I suspected, I found no way to correctly cast a control to access the content of a Container Control.
