Struct gabelstaplerwm::wm::layout::stack::DStack

pub struct DStack { /* fields omitted */ }

Dual stack layout.

+-+---+-+
| |   | | A: left stack, hidden if fixed=false and num_windows <= 2
|A| B |C| B: master window
| |   | | C: right stack, hidden if fixed=false and num_windows <= 1
+-+---+-+

New windows are added as slaves to the right stack, being pushed to the left one to keep the amount of windows balanced. The following invariant holds: num_slaves_left <= num_slaves_right.

Methods

impl DStack

fn new(master_factor: u8, fixed: bool) -> DStack

Construct a sane DStack.
