Detailed Description#

Use insert() to receive an instance of Key generated by the pixmap cache. You can store the key in your own objects for a very efficient one-to-one object-to-pixmap mapping.

class PySide6.QtGui.QPixmapCache.Key#

PySide6.QtGui.QPixmapCache.Key(other)

Parameters:: other – PySide6.QtGui.QPixmapCache.Key

Constructs an empty Key object.

PySide6.QtGui.QPixmapCache.Key.isValid()#

Return type:: bool

Returns true if there is a cached pixmap associated with this key. Otherwise, if pixmap was flushed, the key is no longer valid.

PySide6.QtGui.QPixmapCache.Key.__ne__(key)#

Parameters:: key – PySide6.QtGui.QPixmapCache.Key
Return type:: bool

PySide6.QtGui.QPixmapCache.Key.__eq__(key)#

Parameters:: key – PySide6.QtGui.QPixmapCache.Key
Return type:: bool

PySide6.QtGui.QPixmapCache.Key.swap(other)#

Parameters:: other – PySide6.QtGui.QPixmapCache.Key
