Link QAction availability to user selection

[theo_ld]

Hello everyone,

I've created some QActions into QMenus, I'd like to disable them if no selection is done in my main widget.
How can I do it ?

I'm aware of the QAction->setEnabled() method, but how can I link it to the user mouse selection ?

Hi,

What kind of selection are you referring to ?

[theo_ld]

It's a user left-click selection of a QItemSelectionModel on a QTableView. The user data is stored into a QTableModel.

Then add a slot to the class that manages these actions and connect it to the selectionChanged signal of your selection model. In there check whether the selection is empty and update the action state accordingly.

I try that, thanks for you advice !

@SGaist I tried this, but the selectionChanged signal doesn't exist in the QAction class.

    connect(callAct, &QItemSelectionModel::selectionChanged, ipWidget, &IpWidget::onSelectionChanged);

Because it's a signal of QTableView.
