Brandon Scott	a4d52b122d	FileManager+LibGUI: Fix two folder-related crashes (#569) ... Fix a crash when opening a folder, and another one when trying to open a newly created folder. It was not safe to modify a GModelSelection while it's being iterated over. Fixes #536.	2019-09-17 09:26:10 +02:00

Andreas Kling	b0f42ee672	GModelSelection: Add contains_row(int) and toggle(GModelIndex)	2019-09-07 19:33:58 +02:00
Andreas Kling	82559e211d	LibGUI: Add GModelSelection to help implementing multiple-select views ... Each GAbstractView now has a GModelSelection backed by a simple HashTable<GModelIndex>. When the selection changes somehow, the view gets notified via the notify_selection_changed() callback. In the future it will probably make sense to move to using some kind of ranges as the internal representation instead.	2019-09-07 19:21:07 +02:00
