This example shows one way you can partition your window into a header
|
||||
and sidebar. Here, the header and sidebar have a fixed width, while the
|
||||
rest of the content sizes with the window.
|
||||
|
||||
It might be a new way of thinking about window layout to do things this
|
||||
way - perhaps [GridLayout] more matches your style of thought - but the
|
||||
concept here is to partition the window into sub-boxes with a particular
|
||||
size, then partition those boxes into further boxes.
|
||||
|
||||
$(IMG //arsdnet.net/minigui-screenshots/windows/layout.png, The example window has a header across the top, then below it a sidebar to the left and a content area to the right.)
|
||||
|
||||
So to make the header, start with a child layout that has a max height.
|
||||
It will use that space from the top, then the remaining children will
|
||||
split the remaining area, meaning you can think of is as just being another
|
||||
box you can split again. Keep splitting until you have the look you desire.
