This Qt code example demonstrates optimised pixel drawing to the QPixmap picture. The application provides a number of drawing options that can be selected from a toolbar. All application graphics have been implemented as Scalable Vector Graphics (SVG) icons. To enhance the drawing experience, the application updates only a small area of the screen when the user is drawing.
The updated example application has been tested to on Maemo (Nokia N900 PR1.2) with Qt 4.6.2 and on Symbian^3, Symbian S60 5th Edition, and Windows XP with the Qt 4.6.3 release.
Important classes: QPixmap, QPainter, QWidget, QColorDialog, QFileDialog.
