Qt Designer: make widgets inside QToolBox pages expand

SherrilB

I have an issue using Qt Designer. I am unable to make widgets belonging to QToolBox pages expand with QToolBox. (also with QTabWidget.)

Here is the object inspector.

The initial window when using ctrl-R.

After expanding the window using mouse.

The toolbox expands but not its contents.

As you can see I have a lot of (probably) extraneous widgets in attempting to work through this. I (think) I understand that for a widget to expand it has to be associated with a QLayout.

But, so far, no joy.

Any help will be appreciated.

In your Designer object inspector, each of the layout icons with a "stop" symbol superimposed (e.g. ignore_dirs_toolbox_page) is a widget without a layout applied to it. Layout-free widgets will not resize their content. Note, this is different to nesting a layout inside another which, for example, is what ignore_dirs_layout is.

Select ignore_dirs_toolbox_page
Apply a horizontal layout (from the designer toolbar or context menu IIRC)
You then do not need ignore_dirs_layout
Repeat applying layout to "frame", "ignote_dir_frame" ...

@ChrisW67 Thank you for your excellent reply.

I'm learning a little bit each day. Two things I learned from your reply were:

the stop sign indicates a widget not associated with a layout.
that an widget in the Object Inspector can be right clicked to associate the object with a layout.

I really appreciate the help.
