QTableView QModelIndex isVisible?
-
I am using Qt 5.4.0 + Windwos 8.1 64Bit.
I created a QTableView using ProxyWidget for QGraphicsView.
This item is adjustable in size.
When the size of the QTableView decreases, a scrollbar is created.
In that state, I want to know the QModelIndex lowest column, highest column, lowest row, and highest row.
How can I know?
Thank you.

Hi
What is currently being shown is being handled by the View.
The model does not know anything about it.
However, you can use
https://doc.qt.io/qt-5/qabstractitemview.html#visualRect
to check if a given index() is shown.
They talk about it here

Does the viewport Rect of the QTableView meet the Rect of each QModelIndex you tell me? Judging by the comparison is showing on the screen. Thank you.

Hi
The viewport draws the items.
each item has a rect, and the viewport has a rect
so we can use visualrect to see if an item is within the viewport and therefore visible.- Does the viewport Rect of the QTableView meet the Rect of each QModelIndex you tell me?
Im not 100% sure what this sentence means, but i feel like saying yes :)
