2001-08-21 Peter Williams <peterw@ximian.com> * folder-browser-ui.c (fbui_sensitize_items): Rename to fbui_real_sensitize_items. Now we queue a change and set up a timeout, making sure weed out redundant changes, fixing flicker. (fbui_sensitize_timeout): New function. The timeout. (fbui_real_sensitize_items): Semi-new function. Rename of old fbui_sensitize_items. (folder_browser_ui_set_selection_state): Pass the FB instead of only the UIC to sensitize_items. (folder_browser_ui_message_loaded): Same. * folder-browser.c (folder_browser_destroy): Kill the new timeout if it is registered. * folder-browser.h: Add some members to FolderBrowser for keeping track of the queue of changes. svn path=/trunk/; revision=12343
