Functionality required by a window

Required methods

fn title(&self) -> &str

Get the window title

fn restrict_dimensions(&self) -> (bool, bool)

Whether to limit the maximum size of a window

All widgets' size rules allow calculation of two sizes: the minimum size and the ideal size. Windows are initially sized to the ideal size. This option controls whether the window size is restricted by the calculated minimum size and by the ideal size.

Return value is (restrict_min, restrict_max). Suggested is to use (true, true) for simple dialog boxes and (true, false) for complex windows.

fn add_popup(
    &mut self,
    size_handle: &mut dyn SizeHandle,
    mgr: &mut Manager,
    id: WindowId,
    popup: Popup
)

Add a pop-up as a layer in the current window

Each Popup is assigned a WindowId; both are passed.

fn resize_popups(&mut self, size_handle: &mut dyn SizeHandle)

Resize popups

This is called immediately after Layout::set_rect to resize existing pop-ups.

fn remove_popup(&mut self, mgr: &mut Manager, id: WindowId)

Trigger closure of a pop-up

If the given id refers to a pop-up, it should be closed.

Provided methods

fn handle_closure(&mut self, _mgr: &mut Manager)

Handle closure of self

This allows for actions on destruction, but doesn't need to do anything.
