breakpoint inside QComboBox subclass not working
- by yan bellavance
I have subclassed QComboBox to customize it for special needs. The subclass is used to promote QComboBoxes in a ui file from QtDesigner. Everything works except that when I put a break point in a slot, the program does not stop at the breakpoint. I do however know that it is being called from the result it generates. I checked other slots in my program and they work fine with breakpoints. Doing a clean and rebuild all did not fix it. What could be causing this and is there anything I can do about it? The slot in question is the only one in the subclass and is called "do_indexChanged()". You can find the slot on line 37 of the class header below and the signal-slot connection on line 10 of the class source file.
