pub fn disable(&mut self) -> &mut Self

Disables the window, must call Windows::commit for this change to be seen.

source

pub fn reset(&mut self) -> &mut Self

Resets the window to it’s default state, must call Windows::commit for this change to be seen. The default state is the window disabled with nothing rendered.

source

pub fn set_blend_enable(&mut self, blend: bool) -> &mut Self

Sets whether the blend is enabled inside of this window, must call Windows::commit for this change to be seen.
