Inserting a QAction into a QLayout

[JulienMaille]

Hello,
I'm trying to change my app layout and while moving a bunch of buttons from one place to another, I came across a QAction (currently located in a QToolBar) that I would like to move to a QLayout.
I tried to call myLayout->insertWidget(0, ui->myToolbar->widgetForAction(ui->myAction));
The button will disappear from the toolbar but does not appear in the layout.
Is there a way to achieve this?

Thanks in advance

An action is not a widget so you can't add it to a layout. What do you really want to do? If you want to execute an action after e.g. a button was pressed then add a button and connect the appropriate signal to the action.

@Christian-Ehrlicher ui->myToolbar->widgetForAction(ui->myAction) is a widget, not an action.
I would prefer to create a new widget for this action. Otherwise, the same widget will be in two layouts.

Hi,

You can associate an action with several widgets for example you can use the same action in a toolbar and a menu.

He's not the original poster :)
I would like the widget to react to the QAction visible/disable state (event the tooltip text is shared accross widgets), juste like other QWidgets associated to that QAction.
As @SGaist said a QAction can be present in several toolbars and menus.

So still don't understand the problem. Then add the action to e.g. a QPushButton or similar... and action can be associated to more than one widget: https://doc.qt.io/qt-5/qaction.html#associatedWidgets

I'm not sure I understood how I can add my own QPushButton to the associatedWidgets

[Christian Ehrlicher]

Via QWidget::addActionas described in the link. But it will not help much since a QPushButton does not react on QEvent::ActionChanged - only a QToolButton or QMenu and some others do. Therefore either derive from QPushButton and do it by your own or, as I already said in my first post: 'If you want to execute an action after e.g. a button was pressed then add a button and connect the appropriate signal to the action.'

[JulienMaille]

As you said addAction() does not help with my request. It will note even trigger the associated action

[SGaist]

Why use a QPushButton if you want to move a QToolButton around ?

[JulienMaille]

@SGaist what are you suggesting? Is there a way I can easily insert a QAction in a layout as a QToolButton?
If I need to create my own toolbutton, connect all the signals and icon/title changes myself, then it defeats the whole purpose of using a QAction

[Christian Ehrlicher]

Add a QToolButton to the layout and add the action with QWidget::addAction() as I already told you and the documentation tells you.

[JulienMaille]

I have added a QToolBar in my layout, and add the actions to the toolbar, it works and I think that is the right way to do this.

This doesn't work. It will add a dropdown icon suggesting the toolbutton has a menu and nothing else

[Christian Ehrlicher]

Then use signals/slots
