Description

If I save a composer, close the project and then open it again, it forgets the settings for render preview - cache.
It also forgets the page zoom level (maybe not so easy to maintain if the window has changed size).

Call QgsComposer::restoreComposerMapStates in QgsComposer:changeEvent,
not in showEvent (latter does not work reliably with some window
managers, such as openbox) (fix #6085)

History

#1 Updated by Marco Hugentobler almost 12 years ago

This is a problem on gnome, the composer does not receive a show event when visible (because to make project loading faster, the composermaps are created in rectangle preview mode and the maps are drawn when the composer is first opened). It works on KDE (and afaik also on windows).
