How to keep multi-selection in QTreeView?

[lovehouye]

Hello,

Here is a QTreeView, first & second columns are text, the third column is a push button.

The requirement is: If multi-select the rows, and then click one "Download" button, all the selected items can be downloaded. And the multi-selected rows still keep selection.

Currently: The download function has been implemented. But if I click one "Download" button, the row with the button clicked is selected, other rows are not selected.

Question:
How can I keep the selection after click the "Download" button? Thanks!

Hope somebody can help me. Thanks again.

Hi,
Maybe the selection model (QItemSelectionModel) of your view might help your problem.
