Overview

This code example shows how to get notification when the screen mode changes using QWidget::resizeEvent(). This method gets called when the screen mode changes, so you have to implement that virtual method in your class.

This snippet can be self-signed.

Preconditions

  • Download and install the Qt SDK

Source

//resizeEvent() method get called when user change screen mode.
void ResizeEvent::resizeEvent (QResizeEvent* event)
{
QSize widgetSize = event->size();
//Resize your custom control according to new size.
QMainWindow::resizeEvent(event);
}

Postconditions

The code snippet is expected to notify change in screen mode.
