Expand description

Trait containing all AspectFrame methods.

Implementors

AspectFrame

Required Methods

Set parameters for an existing AspectFrame.

xalign

Horizontal alignment of the child within the allocation of the AspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned)

yalign

Vertical alignment of the child within the allocation of the AspectFrame. This 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.
