Hi list,
I have a problem with my GUI :-(
In my program i have three sliders:
Gtk::HScale m_scalebutton1, m_scalebutton2, m_scalebutton3;
When the user changes one of the sliders the following function is executed:
void myGUI::on_scale_change()
{
m_scalebutton1.set_sensitive(false);
m_scalebutton2.set_sensitive(false);
m_scalebutton3.set_sensitive(false);
/* Calculate something (takes some seconds) */
[...]
m_scalebutton1.set_sensitive(true);
m_scalebutton2.set_sensitive(true);
m_scalebutton3.set_sensitive(true);
return;
}
The problem is that the three sliders aren't greyd out during the
calculation. While the calculation runs the sliders still look normal.
When I try to change the sliders during the calculation nothing happens
(sliders are frozen). But after the calculation the change is performed
and the sliders jump to the position where i tried to drag em to.
Then the function on_scale_change() is executed again, because the value
of the slider changed.
As the calculation takes some time, the user should not be able to
change the sliders during the calculation.
I hope you see my problem. What can I do?
Alex
