Here's a part of the code reduced to the (very very) minimum.
I hope it will be enought significant for you to see what's wrong.
int Toolbar::handle(int e)
{
static int xOff = 0, yOff = 0;
switch(e)
{
case FL_PUSH:
if(Fl::event_button() == FL_LEFT_MOUSE) //set the offsets in order
{ // to draging the widget
xOff = x() - Fl::event_x_root();
yOff = y() - Fl::event_y_root();
xPos = xOff + Fl::event_x_root();
yPos = yOff + Fl::event_y_root();
xCursOff = Fl::event_x() - x();
yCursOff = Fl::event_y() - y();
position(xOff + Fl::event_x_root(),
yOff + Fl::event_y_root());
...//some code
}
return 1;
case FL_RELEASE:
//some code relative to initializing flags
return 1;
case FL_DRAG:
if((Fl::event_state()&FL_BUTTON1) == FL_BUTTON1)
{
//there's a lot much more code here but it could be
//resumed to: draging the widget.
position(xOff + Fl::event_x_root(), HMENUBAR);
xPos = xOff + Fl::event_x_root();
yPos = yOff + Fl::event_y_root();
this->redraw();
}
return 1;
default:
return Fl_Group::handle(e);
}
return Fl_Group::handle(e);
}
