#9689 assigned bug
DisableUpdates()/EnableUpdates doesn't seem to work with Layout API

Description
While making changes to Tracker's Find to use the Layout API, discovered a drawing bug when layout changes were triggered by a function in the overridden BWindow::MessageReceived
hook.
The window calls DisableUpdates()
, makes layout changes, and then calls EnableUpdates()
, but the window is not redrawn correctly. Even adding UpdateIfNeeded()
after EnableUpdates()
did not cause the window to redraw.
Removing the calls to disable/enable updates allowed the window to redraw correctly.
My current changes are available at https://github.com/jessicah/haiku/tree/find-panel-layout-api, SwitchToTemplate.

Thanks for the report! I think there might be some code in place to support this, but my faint memory is that I never tested this very well and there might be situations, specifically moving around BViews, which circumvent the blocked updates. I.e. support for this feature is probably incomplete.
