Dear Rooters
I would like to enable a button only, when I select an item in
TGListBox, but disable the button when deselecting all items
by clicking in the white space.
Sorrowly, the signal TGListBox::Selected() is only emitted,
when an item is selected. Is there a way to deselect the button?
I am not sure but maybe adding the following in TGListBox::
ProcessMessage() could help:
if(entry)
......
Selected((Int_t) parm1);
else
Selected((Int_t) -1);
Thank you in advance
Best regards
Christian
