class KPixmapRegionSelectorDialog |
|
A dialog that uses a KPixmapRegionSelectorWidget to allow the user
to select a region of an image. If you want to use special features
like forcing the selected area to have a fixed aspect ratio, you can use
See also pixmapRegionSelectorWidget() to get the pointer to the KPixmapRegionSelectorWidget object and set the desired options there. There are some convenience methods that allow to easily show a dialog for the user to select a region of an image, and just care about the selected image.
