What is QT-Creator's equivalent to WinForms Dock-Fill?

Question

I have a QTreeView widget placed inside a QDockWidget:

I want to set the properties of the QTreeView, that it automatically fills the whole available client drawing area (similar as WinForms DockFill property).

How can this be achieved with the QT-Designer?

_{Note: I've been playing around with the QTreeViews sizePolicy properties. If these are set to Expanding (as is the default) the accepted answer works out out of the box.}

In Qt Designer, right-click the dock-widget, and then select Lay out -> Lay Out Vertically from the menu. Or you can just click on the dock-widget to select it, and then use the equivalent layout toolbar buttons.

If you want to maximise the space taken up by the tree-view, select the first child widget of the dock widget (it will probably be shown as dockWidgetContents in the Object Inspector pane). Then scroll down to the bottom of the Property Editor, and reset all the margins to zero.

Unfortunately that choice isn't available from the Layout menu. The only choice there is _Adjust Size_. – πάντα ῥεῖ Nov 13 '16 at 21:47
@πάνταῥεῖ. As I said, you need to select the **dock-widget**, not the tree-view. You can only set layouts on container widgets. – ekhumoro Nov 13 '16 at 23:14
I did as you told and the `QTreeView` resizes with the `QDockWidget` now But it doesn't fill the whole client drawing area, which is what I'm finally after. Any other advice to achieve that? – πάντα ῥεῖ Nov 14 '16 at 17:15
Actually setting the `sizePolicy` horizontal and vertical values to `Expanding` seems to do the job + setting the margins as you said. – πάντα ῥεῖ Nov 14 '16 at 17:54
@πάνταῥεῖ. Those are the default values for a tree-view, so you must have changed them at some point. – ekhumoro Nov 14 '16 at 18:16
Yeah. Could well be. I've been playing around a lot. – πάντα ῥεῖ Nov 14 '16 at 18:17
