Bogue.SpaceSourceAdjust various spacing and sizes of layouts.
These functions do not take effect immediately! They will be executed, in the order of their invocation, at the next graphics frame (or at startup if they are invoked before the start of the mainloop).
When used in a Layout.flat structure, this special empty layout will automatically expand in order to fill the available width in the parent house. The other inhabitants keep the width they had at the execution of the hfill invocation. Their height is resized as usual. Only one hfill layout should be used in a given house.
This will set the width of the room (layout) in order to occupy the whole width of its house.
Like hfill, but applies to the specified layout instead of creating an empty one.
When used in a Layout.tower structure, this special empty layout will automatically expand in order to fill the available height in the parent house. See hfill.
