I created lots of QPushButtons, added clicked signal and a slot name ´deneme()´ to all of the buttons with QT DESIGNER and the thing I want to do is; when I clicked any button, some operation should be done and lastly the button should be disabled but we do not know which button is clicked. I know I can disable the buttons with setEnabled() and isEnabled() but I do not know how to disable them.

In Qt for Symbian, when I call setEnabled (false) on my QPushButton, I expected the button text to automatically turn gray. It does not.
If I understood correctly you connected various QPushButtons to the same slot. Inside of the slot deneme() you want to know which of the buttons was clicked. You can do something like:
void deneme() { QPushButton * b = qobject_cast<QPushButton *>(sender()); if (b) { if (b == button1) { //button1 clicked //doSomething(); } else { if (b == button2) { //doSomething(); } } b->setEnabled(false); } } If you love us?
