|string text||Text to display on the window title, should be unique as it will be used as the window’s id.|
|Pose& pose||The pose state for the window! If showHeader is true, the user will be able to grab this header and move it around.|
|Vec2 size||Physical size of the window! Should be set to a non-zero value, otherwise it’ll default to 32mm. If y is zero, it’ll expand to contain all elements within it.|
|UIWin windowType||Describes how the window should be drawn, use a header, a body, neither, or both?|
|UIMove moveType||Describes how the window will move when dragged around.|
Begins a new window! This will push a pose onto the transform stack, and all UI elements will be relative to that new pose. The pose is actually the top-center of the window. Must be finished with a call to UI.WindowEnd().
