def invalidate(self):
# Python wrapper for gimp_preview_invalidate()
This function starts or renews a short low-priority timeout. When the timeout expires, the GimpPreview::invalidated signal is emitted which will usually cause the self to be updated.
This function does nothing unless the "Preview" button is checked.
During the emission of the signal a busy cursor is set on the toplevel window containing the self and on the preview area itself.
