Struct gdk4::ToplevelSize

source · [−]

#[repr(transparent)]
pub struct ToplevelSize { /* private fields */ }

Expand description

The ToplevelSize struct contains information that is useful to compute the size of a toplevel.

Implementations

impl ToplevelSize

pub fn bounds(&self) -> (i32, i32 )

Retrieves the bounds the toplevel is placed within.

The bounds represent the largest size a toplevel may have while still being able to fit within some type of boundary. Depending on the backend, this may be equivalent to the dimensions of the work area or the monitor on which the window is being presented on, or something else that limits the way a toplevel can be presented.

Returns

`bounds_width`

return location for width

`bounds_height`

return location for height

pub fn set_min_size(&mut self, min_width: i32, min_height: i32)

Sets the minimum size of the toplevel.

The minimum size corresponds to the limitations the toplevel can be shrunk to, without resulting in incorrect painting. A user of a Toplevel should calculate these given both the existing size, and the bounds retrieved from the ToplevelSize object.

The minimum size should be within the bounds (see bounds()).

`min_width`

the minimum width

`min_height`

the minimum height

pub fn set_shadow_width(&mut self, left: i32, right: i32, top: i32, bottom: i32)

Sets the shadows size of the toplevel.

The shadow width corresponds to the part of the computed surface size that would consist of the shadow margin surrounding the window, would there be any.

`left`

width of the left part of the shadow

`right`

width of the right part of the shadow

`top`

height of the top part of the shadow

`bottom`

height of the bottom part of the shadow

pub fn set_size(&mut self, width: i32, height: i32)

Sets the size the toplevel prefers to be resized to.

The size should be within the bounds (see bounds()). The set size should be considered as a hint, and should not be assumed to be respected by the windowing system, or backend.

`width`

the width

`height`

the height
