- void toggled ( bool b )

## Member Function Documentation

### QAction::QAction ( QObject * parent, const char * name )

Use one of the QAction constructors that doesn't take a name argument and call setObjectName() instead.

### QAction::QAction ( const QString & text, const QKeySequence & shortcut, QObject * parent, const char * name )

Use one of the QAction constructors that doesn't take a name argument and call setObjectName() instead.

### QAction::QAction ( const QIcon & icon, const QString & text, const QKeySequence & shortcut, QObject * parent, const char * name )

Use one of the QAction constructors that doesn't take a name argument and call setObjectName() instead.

### QKeySequence QAction::accel () const

Use shortcut() instead.

### void QAction::activated ( int i = 0 ) `[signal]`

Use triggered() instead.

### bool QAction::addTo ( QWidget * w )

Use QWidget::addAction() instead.

For example, if you have code like

        action->addTo(widget);

you can rewrite it as

        widget->addAction(action);

### QIcon QAction::iconSet () const

Use icon() instead.

### bool QAction::isOn () const

Use isChecked() instead.

### bool QAction::isToggleAction () const

Use isCheckable() instead.

### QString QAction::menuText () const

Use text() instead.

### bool QAction::removeFrom ( QWidget * w )

Use QWidget::removeAction() instead.

For example, if you have code like

        action->removeFrom(widget);

you can rewrite it as

        widget->removeAction(action);

### void QAction::setAccel ( const QKeySequence & shortcut )

Use setShortcut() instead.

### void QAction::setIconSet ( const QIcon & i )

Use setIcon() instead.

### void QAction::setMenuText ( const QString & text )

Use setText() instead.

### void QAction::setOn ( bool b )

Use setChecked() instead.

### void QAction::setToggleAction ( bool b )

Use setCheckable() instead.

### void QAction::toggled ( bool b ) `[signal]`

Use checked() instead.
