It can be used as a QPaintDevice object or can be loaded into another widget, typically a label or button. Qt API has another similar class QImage, which is optimized for I/O and other pixel manipulations. Pixmap, on the other hand, is optimized for showing it on screen. QGraphicsView can cache pre-rendered content in a QPixmap, which is then drawn onto the viewport. The purpose of such caching is to speed up the total rendering time for areas that are slow to render. Texture, gradient and alpha blended backgrounds, for example, can be notibly slow to render; especially with a transformed view. iptv stream player login The form of the main window consists of the widget and placed it QGraphicsView object. paint.h This file is declared a customized graphical scene, as well as a timer with a slot for this timer, which is used for the correct processing of the application is resized. #ifndef PAINT\_H #define PAINT\_H #include <QWidget> #include <QTimer>For example: scene = QGraphicsScene() scene.addText("Hello, world!") view = QGraphicsView(scene) view.show() You can explicitly scroll to any position on the scene by using the scroll bars, or by calling centerOn () .
