在QT中启用触摸屏时出错

Question

I want to enable touchscreen in QT, so I gave:

ui->pushButton->setsetAttribute(Qt::WA_AcceptTouchEvents,true); 

but it shows the following error:

error: no matching function for call to 'QPushButton::setAttribute(bool)' ui->pushButton->setAttribute((Qt::WA_AcceptTouchEvents,true)); ^

Answer 1

Remove the superfluous parentheses:

ui->pushButton->setAttribute(Qt::WA_AcceptTouchEvents,true);

vs.

ui->pushButton->setAttribute((Qt::WA_AcceptTouchEvents,true));
