How to detect when icon clicked in item delegate ?



  • Hi
    i have QTableView item delegate , which there i construct text and 2 icons one for delete the table row and one to do some other action .
    my question is how to detect and trigger function when my mouse is click on one of the icons in the item delegate ?
    do i need to post code ?



  • You should reimplement the editorEvent() virtual method from [[doc:QAbstractItemDelegate]]. From the documentation:
    [quote]Mouse events are sent to editorEvent() even if they don't start editing of the item. This can, for instance, be useful if you wish to open a context menu when the right mouse button is pressed on an item.[/quote]
    So, you can handle mouse events from this method. It is up to you to determine if a click is on an icon or not.

    For communication of the event, I would give the delegate one or more signals (that include a QModelIndex as an argument) that communicate the triggering of the event.
