Implement "gray" when uicontrol radiobutton/checkbox are disabled (bug #57128)
* BaseControl.cc (updatePalette): Call setColor() with additional argument of
"QPalette::Active" and again with "QPalette::Inactive" so that colors are set
only for specific roles.
* CheckBoxControl.h (CheckBoxControl): Declare new private member function
update().
* CheckBoxControl.cc (CheckBoxControl): Check for "Enable" property value of
"inactive" and call setCheckable (false) if found.
* CheckBoxControl.cc (update): New function to intercept and handle change to
"Enable" property before forwarding to BaseControl.
* RadioButtonControl.cc (RadioButtonControl): Check for "Enable" property value
of "inactive" and call setCheckable (false) if found.
* RadioButtonControl.cc (update): New function to intercept and handle change
to "Enable" property before forwarding to BaseControl.
