Overview

This code example shows how to get screen coordinates and screen size in a Qt application. The API QDesktopWidget::screenGeometry() returns the application rect (screen size of device) and API QDesktopWidget::availableGeometry() returns client rect (screen size minus status pane). It is useful in UI applications that do not use layout managers by implementing virtual QWidget::resizeEvent().

This snippet can be self-signed.

Preconditions

  • Download and install the Qt SDK.

Source

QDesktopWidget* desktopWidget = QApplication::desktop();
//get client rect.
QRect clientRect = desktopWidget->availableGeometry();
 
//get application rect.
QRect applicationRect = desktopWidget->screenGeometry();


Postconditions

You will get application rect.
