- when restoring state, the old dock widgets would remove themselves
from their old dock areas and add themselves to the new dock areas. The
old dock areas that are empty would then delete themselves.
- That is a problem when the old overlay dock container would still try to
access the old dock areas, not knowing their deleted, causing a crash.
Previous:
- It would just hide the overlay dock widget and leave the side tabs
still visible
- Close button, toggle view action would simply collapse the dock widget
intsead of completely hiding it
Current:
- Now toggle view and collapse functionality are separated.
- Toggle view will now hide the side tab bars completely
- Close button and toggle view action will completely hide it
- Collapse view will simply hide the overlay dock container without
hiding the side tabs
- Handled logic for floating widgets and toggling view
Note: this does not include the py file, To be added in a different
commit
- Added a better API to programatically add the overlay areas in the
CDockManager
This fixes a crash which could occur when restoring the state of a floating container to a non-floating container.
This was because `ads::CDockContainerWidget::RestoreState()` will unconditionally assume this is floating if the XML has the `Floating` boolean set, and will dereference `floatingWidget()`. If this isn't floating, `floatingWidget()` will return `nullptr`, leading to a crash when it's subsequently used.
Fixes#379.
Updated the setting of central widget with option to set where the possible old central widget will be placed. Fixed option of "unsetting" central widget by setting it to nullptr.
Adde option to set a dock widget as central widget. It influences resizing behavior of the splitters. The central widget will be stretched with the main window and remaing dock widgets and threir respective areas will be resized only vertically if docked left or right and horizontaly if docked top or bottom
