QWidgetAction & QToolBar - no actionTriggered signal...

Dariusz

Hey

When I create QLineEdit as my QWidget action by subclassing QWidgetAction and connect :

    connect(mEditor, &QLineEdit::editingFinished, this, &QWidgetAction::trigger);
    connect(mEditor, &QLineEdit::textChanged, this, &QWidgetAction::trigger);

When I go to my toolbar and change the text my toolbar does not get triggered with new text...

How can I connect them? I should be getting toolbar::actionTriggered signal if I'm not wrong ?

I add my action in this way >

toolbar->addAction(static_cast<testWidgetAction *>(obj));

TIA

@Dariusz said in QActionWidget & QToolBar - no actionTriggered signal...:

toolbar->addAction(static_cast<testWidgetAction *>(obj));

What is obj here? If it is already an instance of testWidgetAction why do you cast it? What is testWidgetAction?
Also I don't see any addAction() overloads in QToolBar which take an action pointer as its first parameter.

@jsulm Hey addAction() comes from QWidget that is being inherited by QToolbar, it calls createWidget() by itself and handles that. I though that qtoolbar has its own signal connection system that would connect to QWidgetAction automatically. Or that QWidget Would do this.

Esentially
QToolBar->addAction(new QWidgetAction()) does not automatically connect to toolbar as I though it would.

@Dariusz Maybe I'm blind but I can't find an addAction() overload with a QAction parameter. All I can see is:

addAction(const QString &) : QAction *
addAction(const QIcon &, const QString &) : QAction *
addAction(const QString &, const QObject *, const char *) : QAction *
addAction(const QIcon &, const QString &, const QObject *, const char *) : QAction *
addAction(const QString &, Functor ) : QAction *
addAction(const QString &, const QObject *, Functor ) : QAction *
addAction(const QIcon &, const QString &, Functor ) : QAction *
addAction(const QIcon &, const QString &, const QObject *, Functor ) : QAction *
addActions(QList<QAction *> )

Edit I just noticed I messed up title... corrected to QWidgetAction sorry!
