Well, before plugging in the offscreen drawing there was no problem, the draw()
recursion took place.
But on the standard way, i.e. draw() wasn't explicitly called in my program, it
was handled by the framework

Well, the error is as follows:
g++ -Wall -ggdb -c GUI-maxtree-panel-widgets.cxx -I/usr/local/include/
/usr/include/FL/Fl_Group.H: In member function âvoid
GUImaxtreePanelWidgets::drawScrollPanel()â:
/usr/include/FL/Fl_Group.H:56: error: âvirtual void Fl_Group::draw()â is
protected
GUI-maxtree-panel-widgets.cxx:649: error: within this context
This relates to the following wrapper method:
void GUImaxtreePanelWidgets::drawScrollPanel() {
//maxTreeContentScrollWindowGroup->redraw();
maxTreeContentScrollWindowGroup->draw();
}
here I have a complex window widget:
window
+-> scroll
+-> group
+-> complex visualization widget
+-> complex visualization widget
Again, I'm interested in having the children of the group to be redrawn, the
complex visualization widgets.
My naive approach is to define a wrapper method in the window calling the
group's draw(), but for some reason it's a protected method, so this doesn't
work.
a) why is draw() a protected method?
b) how to trigger draw()? I'm thinking of a group->hide(); group->show()
sequence, but it seems clumsy to me ...
