OK, perhaps I'm seeing very different behaviour (with PyQt 4.3 and Qt 4.3.2 on Linux). I found that the group box and its line edit didn't appear at all. > The only thing I could find in the documentation regarding > QToolBar.addWidget() is the reference to not being able to populate the > extension pop up with widgets added using addWidget(), but this only seems > to apply when the toolbar is not owned by the main window.

Yes, this might not be relevant to your problem. > It's not a great problem, as it _does_ show the widget, just not the size I > tell it to use... Oh well, there are worse things in life I suppose. Bear in mind that the group box is imposing its own constraints on the size of everything, and that it will also take up a lot of space on the toolbar. Have you tried inserting a line edit on its own into the toolbar for testing purposes? > Just doing some testing, changing the QLineEdit to a QTextEdit gives some > strange results: the resulting text box shows on the toolbar as a square > of about 150x150 pixels... not exactly an optimum substitution, even > though it is larger than the line-edit :-). QTextEdit has different size constraints to QLineEdit in that it will expand vertically - the Expanding size policy. QGroupBox uses its default width and height in preference to anything else - the Preferred size policy. This typically means that a line edit inside a group box will take up all the space offered to it by the group box, but won't cause the group box to expand. > Toolbars seem to be optimized for showing only toolbuttons, and even those > I found it doesn't like to resize either; I notice the documentation does > speak of the extension pop up being fixed in a future edition, perhaps the > resizing issue will be fixed as well? You can set the default icon size with QToolBar.setIconSize(): http://www.riverbankcomputing.com/static/Docs/PyQt4/html/qtoolbar.html#setIconSize > If I can't make it work I'll just discard the toolbar and replace it with a > layout on the main window. Or you could use a dock widget instead. It may be more suitable than a toolbar for showing large widgets.
