QTreeView context menu item

[JonB]

At present I have a QTreeView, bound to a (derived) QAbstractItemModel. I have a right-click context menu with a QAction, whose triggered connects to a slot. In the slot I need to access which model item was right-clicked, but I don't think I can see that from the action/slot?

How is this easiest achieved?

The only way I see is to as the QTreeView for the current index.

Hi,

Using the customContextMenuRequested signal you can get the index using QTreeView::indexAt.

@SGaist
Thanks, yes, I have seen that approach. And I may indeed change over. But that happens at the context-menu-requested stage, right? I need to know at the QAction-slot-execute phase. So you want me to either:

• Store up the item at the right-click phase, and apply that at the action-phase; or
• Pass the item at the right-click phase as a parameter to the action-slot phase

Is that right? Or am I going doolally?

@Christian-Ehrlicher

The only way I see is to as [edit: "ask"] the QTreeView for the current index.

Thank you. I will investigate tomorrow. I am so tired today :(

IIRC, when you right click on an item, it becomes selected so you can use the QTreeView::selectedIndexes in your action's slot.

@SGaist
Tx so much, I will look tomorrow

The point is, as I think both you & @Christian-Ehrlicher are confirming, the QAction/slot has no concept of which "item" you were on? You either have to look up the item by converting a click coordinate position to an item (QTreeView::itemAt()), or you have to look at whatever item is currently selected ( QTreeView::selectedIndexes). Is that right, that's what I need to know?

[SGaist]

AFAIK, yes.

Thanks guys, I will hopefully report back and close issue tomorrow.
