Splitter Specification

1. Revision History

Version	User	Date	Notes
0.1	Stefan Ivanov	Mar 11, 2020	Initial draft

2. Overview

The Dock Manager provides a framework for complex layouts splitting the view into multiple smaller ones. This can be done recursively in order to create arbitrary layouts that can be manipulated and adjusted at runtime.

3. User Stories

End User Stories

As an end-user I want to:

be able to see two alternative views of the same thing side by side e.g. design surface and code view
be able to resize the split panes by dragging the splitter element
be able to focus the splitter element
be able to use the keyboard to resize the split panes
be able to scroll the content if it doesn't fit in the pane
be able to collapse panes

Developer Stories

As a developer I want to:

define a splitter that lays out panes horizontally, vertically
define a splitter pane as not resizable
define an arbitrary content that is rendered in a splitter's pane
define a splitter that is nested in another splitter's pane
define a default width/height per pane
define a min/max width/height per pane
