Widgets in QToolbar issues
Message 1 in thread
Hi.
I want to add a QLineEdit in a QToolBar, using the method
QToolBar::addWidget(). I think there's some problem in displaying the
widgets. The QLineEdit is expanded to fill the entire empty space of the
toolbar. If I set the maximum width of the QLineEdit, all the QAction in
the toolbar are moved to fill the entire space of the toolbar. Instead,
I expect that the QAction remains on the left and there is a empty space
on the right.
The other problem is that if I try to hide the QLineEdit in the toolbar
with the method QLineEdit::hide(), the QLineEdit remains visible.
Thanks.
Fabio.

the trick is to have a blank QWidget with a layout in the bar and then add
your other widgets in the layout.

Hi Fabio,
In 4.3.1, I had similar problems with QSlider stretching to fill the
toolbar. It was fixed by changing the sizePolicy on the slider.
For the other problem, I think you need to save the action when you add the
widget, then use the action's mathods, not the lineedit's. For example:
QAction lineEditAction = myToolBar->addWidget(..., myLineEdit);
...
lineEditAction->setVisible(false);
Note that Arvid's suggestion of only have one widget in the toolbar, and
everything else within it, might be simpler.
Regards,
Tony Rietwyk.
