Auto resize contents when dialog is resized?

[SPlatten]

I've added a QFormLayout to the centralWidget, the layoutFieldGrowthPolicy is set to ExpandingFieldsGrow, all the labels and other widgets have been added to the form layout, but when I resize the dialog, nothing happens, everything stays the same size...what haven't I done?

@SPlatten Yes, your dialog has no top-layout (you can even see that in designer if you resize the dialog). Right-click on an empty space in your dialog and then select Layout->one_of_the_layouts...

Without more information (code or design screen-shot) hard to say. Probably you did not apply the layout to the dialog.

@jsulm , here is the XML for the UI file:

And a screenshot of the layout in Qt Creator:

@jsulm , I'm confused now, is the centralWidget required at all?

@jsulm , trying it now.

@SPlatten A QDialog is already a QWidget. So, no there is no need for central widget.

@jsulm , works now :) thank you.
