Multisplitter

A WTL window splitter class that can host more than two children

This splitter can be a direct replacement for the existing two-panel WTL splitter. It has some additional features, such as:

• Change vertical / horizontal orientation at run time.
• Add or remove as many panes as you like.
• Resize any pane. This has two modes: Other panes reduce size (proportionally) when a pane is enlarged, or other panes are moved over.
• The size of the panes can be constrained to the size of the splitter container, or allowed to be larger.
• A scroll bar is presented when the size of the panes is greater than the size of the container.

More details are described in the comments in the source.

The demo project is a WTL frame window with a menu. The client area is a multisplitter window. The menu provides demonstration of most of the multisplitter methods.
