Re: Refreshing ROOT gui frame after modifying elements

Hi Suvayu,

OK, I will try to play a bit with that... But note to vertically add frame (one below each other), you should use a TGVerticalFrame (m_EB_frame)
And as a general comment, when you add/remove frames, you should call something like:
MapSubwindows()
Resize(GetDefaultSize())
Layout()

Cheers, Bertrand.
