TableView lazy load & Virtual Mode
Dong last edited by Dong
I'm trying to display a lot of data in TableView.
What I want is Lazy load with Virtual Mode in TableView.
Lazy Load (Or load on demand) : I want the TableView's model only store about 90 items (3 pages * 30 items)
- When scroll down : The items about the View port will be remove & load more items at the end.
- When scroll up : The items under the View port will be remove & load previous items at the begin.
Virtual Mode: I want the Scrollbar show
- Max value : Total items in database (about 100,000)
- Current value : The current "Virtual" scroll value regardless to the real TableView's model items (maximum is 90)
I'm tried to set rowCount => but it is readonly
I'm search for Virtual Mode but not a clue.
I'm think of custom the TableView but I don't know where to start (I'm a newbie with QT)
PS: I'm use QT 5.4.2 MinGW
Anyone can help me? Any sample or suggestion would be great !!!
Many thanks !!!

If you use a QAbstractListModel the data() will be accessed on demand only (tested).
TableView will reuse delegates when scrolling up/down and not create new ones (according to description)
