How to remove slot, created in Designer mode?
c++, qt, qt-designer, qt4, user-interface
Solution
Solution is simple. I didn't remove the declaration of `<class_name>::on_cancelButton_clicked()` from header file. (by Ammar, posted here)
Problem
I've created the button `cancelButton`. Then I've created function-slot `on_cancelButton_clicked()` for it using context menu item `Go to slot`. But, after a while, I've deleted this button (it wasn't longer needed), and tried to delete that function, but compiler gives error `undefined reference to <class_name>::on_cancelButton_clicked()`. I've made cleanup of build folder (and removed it), checked for some lines in ui file that can point to this function, but i didn't found anything.
