Struct gtk4::AspectFrame
source · #[repr(transparent)]pub struct AspectFrame { /* private fields */ }Expand description
AspectFrame preserves the aspect ratio of its child.
The frame can respect the aspect ratio of the child widget, or use its own aspect ratio.
CSS nodes
AspectFrame uses a CSS node with name frame.

Implementations§
source§impl AspectFrame
impl AspectFrame
sourcepub fn new(xalign: f32, yalign: f32, ratio: f32, obey_child: bool) -> AspectFrame
pub fn new(xalign: f32, yalign: f32, ratio: f32, obey_child: bool) -> AspectFrame
Create a new AspectFrame.
xalign
Horizontal alignment of the child within the parent. Ranges from 0.0 (left aligned) to 1.0 (right aligned)
yalign
Vertical alignment of the child within the parent. Ranges from 0.0 (top aligned) to 1.0 (bottom aligned)
ratio
The desired aspect ratio.
obey_child
If true, @ratio is ignored, and the aspect
ratio is taken from the requistion of the child.
Returns
the new AspectFrame.
sourcepub fn builder() -> AspectFrameBuilder
pub fn builder() -> AspectFrameBuilder

This method returns an instance of AspectFrameBuilder which can be used to create AspectFrame objects.
sourcepub fn is_obey_child(&self) -> bool

allocation of the AspectFrame.
Returns
the vertical alignment
sourcepub fn set_obey_child(&self, obey_child: bool)
pub fn set_obey_child(&self, obey_child: bool)
Sets whether the aspect ratio of the child’s size
request should override the set aspect ratio of
the AspectFrame.
obey_child
If true, @ratio is ignored, and the aspect
ratio is taken from the requisition of the child.
sourcepub fn set_xalign(&self, xalign: f32)
pub fn set_xalign(&self, xalign: f32)
Sets the horizontal alignment of the child within the allocation
of the AspectFrame.
xalign
horizontal alignment, from 0.0 (left aligned) to 1.0 (right aligned)
sourcepub fn set_yalign(&self, yalign: f32)
pub fn set_yalign(&self, yalign: f32)
Sets the vertical alignment of the child within the allocation
of the AspectFrame.
yalign
horizontal alignment, from 0.0 (top aligned) to 1.0 (bottom aligned)
