Hi,
I am using a Fl_Table_Row with SELECT_SINGLE mode (base on table exemple).
I did not succeed to have my callback called when the selection change
on mouse drag (the user keep the mouse down on a selected line and move
over the table to change the active selection).
Looking into Fl_Table.cxx around lines 861, when damage_zone is called,
there is no do_callback call.
How can my callback be called on selection change for my case ?
Regards,
David
I join a patch for a simple way to change this behaviour.
If someone has something better, I take it.
(patch over svn branch 1.3)
Regards,
David
