You can get the emitting button with the sender() function from the 
QObject class

This is my problem: I would like to connect the "clicked" signal of several buttons to one and the same function - but this function should know which button sent the signal. Example: one button to increase a value, another to decrease it, and one single function which adds '+1' or '-1' depending on the sending button. Or a row of buttons with a letter, and clicking one searches for all words beginning with this letter in a list.
