A result None indicates that the area is out of view.

pub fn relocate(&self, area: Rect) -> Option<Rect>

Relocate a rect from Layout coordinates to screen coordinates.

A result None indicates that the area is out of view.

pub fn show_handle(&mut self, handle: AreaHandle)

Show the page for this rect.

pub fn show_area(&mut self, area: Rect)

Show the page for this rect.

pub fn first_area(&self, page: usize) -> Option<Rect>

First area for the page. This only returns a value if the page is visible. Use PageLayout::first_area if you want something else.

pub fn first_handle(&self, page: usize) -> Option<AreaHandle>

First handle for the page. This returns the first handle for the page. Does not check whether the connected area is visible.

pub fn set_page(&mut self, page: usize) -> bool
