Drag & Drop multiselection on QTableWidget

Hi all!!

I am developing an application with some qtablewidgets that are multi selection enabled. The point is that I need to avoid the drag & drop multiselection property from the tables. Is there any possibility to set this property to false for the QTableWidget?

Thanks in advance!!

Set the internalMove property of the widget to false. Same for dragEnabled.

Thanks for the reply wysota!

I added these two sentences to the code but nothing change in the qtablewidget behavior:

tblOutputs->setDragEnabled(false);
tblOutputs->setDragDropMode(QAbstractItemView::DragDropMode(t blOutputs->dragDropMode() & ~QAbstractItemView::InternalMove));

In fact, tblOutputs->dragDropMode() returns 0, so it seems that drag and drop is disabled, but it selects multiple rows dragging the mouse from the table while clicking left button. I do not know what´s the problem...

Thanks!

Ohhh.... you wanted to disable selection by dragging? I guess I misunderstood you then. In that case change selectionBehavior to something else than ExtendedSelection.

No, but I need to select multiple rows by clicking on items, but I do not need to select rows by dragging the mouse. I need to disable this behavior, but still continue selecting multiple rows by only clicking on items.

Any idea??

Thanks again!

QAbstractItemView::SelectionMode -- see the different selection modes and choose which fits you best.

The problem is that both of the multiple-selection-options tips "Multiple items can be toggled by dragging the mouse over them". And what I don´t want to happen is exactly that behaviour, to select rows by dragging mouse.

Then your only option is to prevent the view for getting and drag-like events at all by applying an event filter on the view's viewport and filtering out MouseMove events. Alternatively you can probably set the view to NoSelection mode and implement selection yourself the way you like it.

Thanks!

I created a class inherited from QTableWidget and overwrite mouseMoveEvent. Thanks for your support!

Just make sure it doesn't ruin scrolling the widget by dragging the scroll bar.
