Q3CanvasPixmap Class ReferenceThe Q3CanvasPixmap class provides pixmaps for Q3CanvasSprites. More... #include <Q3CanvasPixmap> This class is part of the Qt 3 support library. It is provided to keep old source code working. We strongly advise against using it in new code. See Porting to Qt 4 for more information. Inherits: QPixmap. Public Functions

Detailed DescriptionThe Q3CanvasPixmap class provides pixmaps for Q3CanvasSprites. If you want to show a single pixmap on a Q3Canvas use a Q3CanvasSprite with just one pixmap. When pixmaps are inserted into a Q3CanvasPixmapArray they are held as Q3CanvasPixmaps. Q3CanvasSprites are used to show pixmaps on Q3Canvases and hold their pixmaps in a Q3CanvasPixmapArray. If you retrieve a frame (pixmap) from a Q3CanvasSprite it will be returned as a Q3CanvasPixmap. The pixmap is a QPixmap and can only be set in the constructor. There are three different constructors, one taking a QPixmap, one a QImage and one a file name that refers to a file in any supported file format (see QImageReader). Q3CanvasPixmap can have a hotspot which is defined in terms of an (x, y) offset. When you create a Q3CanvasPixmap from a PNG file or from a QImage that has a QImage::offset(), the offset() is initialized appropriately, otherwise the constructor leaves it at (0, 0). You can set it later using setOffset(). When the Q3CanvasPixmap is used in a Q3CanvasSprite, the offset position is the point at Q3CanvasItem::x() and Q3CanvasItem::y(), not the top-left corner of the pixmap. Note that for Q3CanvasPixmap objects created by a Q3CanvasSprite, the position of each Q3CanvasPixmap object is set so that the hotspot stays in the same position. See also Q3CanvasPixmapArray, Q3CanvasItem, Q3CanvasSprite, QtCanvas, and Porting to Graphics View. Member Function Documentation
