property PixmapChanged: Boolean;
Returns whether the current QPixmap instance has changed or not. You can use that if you're working directly with QT related methods.
Important Note: Due to the nature of QT handling images and bitmap information, there is a need to notify TBitmap32 about changes you made to the QPixmap. You can use this property to do so.
This will copy the QPixmap content as soon as the Bits property is accessed or some internal function is accessing the image data directly. This will make sure that the content is copied from the QPixmap to the internal QImage in TBitmap32.
This property is only available in the CLX version.
