To resize or to not resize a layout

[Antoine Lever]

I'm using a split layout panel to add a west and north panel.  But, I only want the west panel to resize and NOT the north.  Any ideas?

Thanks in advance.

Use a DockLayoutPanel for the north/center non-resizeable separation and a SplitLayoutPanel for the west/center resizeable split.

How do you do that? I was under the impression that you could only add one layoutPanel via RootLayoutPanel.get().  Would you have a code fragment I can look at - thank you very much.

The only constraint is that you add RequiresResize widgets to ProvidesResize widgets. RootLayoutPanel is a ProvidesResize, and all layout panels implement both interfaces (and, for instance, DataGrid is a RequiresResize but not a ProvidesResize, as it's not a container). If you break that ProvidesResize/RequiresResize chain, you have to explicit set the dimensions of the RequiresResize widget.

See https://developers.google.com/web-toolkit/doc/latest/DevGuideUiPanels#Resize (and also search for “Using a LayoutPanel without RootLayoutPanel” in that same page)

It's like:

RootLayoutPanel

--> DockLayoutPanel

     --> NORTH: header

     --> CENTER: SplitLayoutPanel

          --> WEST: side menu

          --> CENTER: content area

It works perfectly!  Thank you!
