How can find which button is clicked.

Hi
How i can identify which button is clicked. I have three buttons connected to the same slot and in this slot i want to handle all three buttons difeerently. isClicked() something like this can solve my problem but i have not find this property.
How i can handle buttons then , i change the background color on clicking and i want that this remain untill another button is not clicked.

You can either use QSignalMapper, or get the emitter's handle using sender() call in the slot, I would prefer the first one.

Thanks for reply but i have solve the problem.
But the background color is not remaining untill another button is clicked. How should do it.

It's not clear what to you said, but I guess you may changing the color some were else, or the slots are being called again

If you want to do something different for each button, this argues for having three different slots.

If you have 3 buttons and each one changes the background to a different colour this sounds like a good situation to put the buttons in a QButtonGroup. The QButtonGroup::clicked signal passes a pointer or id to let you know which button was clicked.

You can add buttons to a QButtongroup via the designer by having all your buttons selected at once and then right clicking.
