Re: [[SOLVED] QPushButton. I click on the button](but nothing not happend.)
Here is my code,
QPushButton *textBtnWin;
textBtnWin = new QPushButton(parent);
connect(textBtnWin, SIGNAL (clicked()), this, SLOT (handleButton()));handleButton(void) {
blnBtnPressed = !blnBtnPressed;
qDebug() << blnBtnPressed;
}for some buttons, the click is not working. In fact the mouse hover also does no changes for these buttons.

Hi
Please show real code. :)
Also if some buttons dont work and some do, it means
you have some sort of bug. (as slot works then) -

Is Your handleButton() function is declared as public slots??
If it is normal public function you cant connect to the signal by above connect statement. -

Still, I tried it making as public slot() but it didn't work -

If you are interested to call this slots as normal member function then public/private is applicable. Also if you are trying to call the slots from QML environment, then slots need to be public only.
