struct GdkPixbuf::PixbufLoader::AreaUpdatedSignal

Overview

This signal is emitted when a significant area of the image being loaded has been updated.

Normally it means that a complete scanline has been read in, but it could be a different area as well.

Applications can use this signal to know when to repaint areas of an image that is being loaded.

Defined in:

lib/gi-crystal/src/auto/gdk_pixbuf-2.0/pixbuf_loader.cr
