why setVisibe not work?
i want to dynamically show or hide a QCombo in a Toolbar.
but setVisibe(false); not work.
while setEnabled() do work.

QAction * QToolBar::addWidget(QWidget * widget)
Adds the given widget to the toolbar as the toolbar's last item.

The toolbar takes ownership of widget.

If you add a QToolButton with this method, the toolbar's Qt::ToolButtonStyle will not be respected.

Note: You should use QAction::setVisible() to change the visibility of the widget. Using QWidget::setVisible(), QWidget::show() and QWidget::hide() does not work.

Hi,

Look again at the function signature: you get a QAction as a result of addWidget.
