Facing difficulties to use share QAbstractItemModel between QTreeView & QListView
Hello,
I have QAbstractItemModel implementation which share in two view [ QTreeView & QListView]
List view contains some filters like… All Type, Type 1, Type 2, Type 3. those types represented as parent item in Tree View.
So when i click on Type 1 from Tree View it will generate index click and set root index of list view by them. so it will display all child’s items from Type 1 will be listed in List View. Its works fine for me but,
When i want to use of combination of filters e.g. like Type 1 & Type 2, so in my list view it should display the list of all child’s of Type 1, & Type 2 but it could not be possible because i can set only one root index at a time to list view. So how can i achieve this ?
And same scenario above is applicable to All Type filter as well, how could i display all child’s of Tree view item to be listed in list view.
Any help will be really appreciated.
Thanks
