From: Federico Mena Quintero Date: Tue, 12 Mar 2013 17:21:35 +0000 (-0600) Subject: filechooserbutton: Do not propagate state from the dialog unless it is active X-Git-Url: http://pileus.org/git/?a=commitdiff_plain;ds=sidebyside;h=3b2182e711ace4a2d6843848208224cd7525d530;p=~andy%2Fgtk filechooserbutton: Do not propagate state from the dialog unless it is active Change of plans to match the tests from the previous commit. The state of the underlying dialog is never reflected by GtkFileChooserButton's API, as the dialog is a transient thing. The file chooser button only updates its state from the dialog, and reflects the dialog's state, when the dialog has been confirmed and dismissed by the user.
