Keep Screen On Example

Demonstrates keeping the screen on while a window is displayed.

The main window contains a checkbox. Toggling it calls QtOhosExtras::setWindowKeepScreenOn() with the window and the checkbox state, so the screen stays awake while the box is checked and the request is released when it is unchecked. The setting is tied to the given window.

     QCheckBox keepScreenOnCheckBox("Keep on", &window);
     QObject::connect(
         &keepScreenOnCheckBox, &QCheckBox::stateChanged, &window,
         [window = &window](int state) {
             QtOhosExtras::setWindowKeepScreenOn(window, state == Qt::Checked);
         });
