<![CDATA[Get bool result of qButton when this is pressed]]>Hello, i need help to obtain the boolean result in a if conditional of a button state.

I have a var called restart, and i need to save a bolean value when i press the button, if is pressed i will save true, if it´s not pressed i will save false.

I need that, because i'm sending in the constructor the value of restart, and i need to capture the moment when is true, becuase later when I release the button the value will be false.

void MainWindow::on_btn_restart_pressed()
{
restart=true;
myOGLW = new MyOpenGLWidget(m_sB,k_sB,b_sB,t_cB,pauser,restart,opc);
}

I hope that can you help whit this!!

Use signals & slots to send a signal to your MyOpenGLWidget which will cause a restart.
https://doc.qt.io/qt-5/signalsandslots.html

Something like this (in your MainWindow)

connect(ui->pushbutton_restart, &QPushButton::clicked, myOGLW, &MyOpenGLWidget::restart);

Then, make your widget reset / restart itself (in myOpenGLWidget class)
