PixbufLoader.connectAreaUpdated

gdkpixbuf pixbuf_loader PixbufLoader

Connect to AreaUpdated signal.

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.
