// A QLayout specifically for the Features window, that tries to make the most
|
|
// of available space, while allowing the user to resize some elements, on the
|
|
// assumption that there are two types of Feature UI
|
|
// - Fixed size widgets like Rotator Controller
|
|
// - Expanding widgets like Map
|
|
// The Feature window is split in to two parts (when horizontal orientation):
|
|
// - Left hand side for fixed widgets which are stacked in vertical columns
|
|
// to fit available height
|
|
// - Right hand side is for expanding widgets inside a Splitter which allows
|
|
// a user to manually set how much space is used for each Feature
|
|
// When vertical orientation, the fixed widgets are in columns at the top, with
|
|
// the expanding widgets underneath (this isn't quite as nice, as the widget
|
|
// heights vary more than the widths)
