GI.Gtk.Objects.AspectFrame

The AspectFrame is useful when you want pack a widget so that it can resize but always retains the same aspect ratio. For instance, one might be drawing a small preview of a larger image. AspectFrame derives from Frame, so it can draw a label and a frame around the child. The frame will be “shrink-wrapped” to the size of the child.

CSS nodes

GtkAspectFrame uses a CSS node with name frame.

Arguments

:: (HasCallStack, MonadIO m)

=> Maybe Text

label: Label text.

-> Float

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

-> Float

yalign: Vertical alignment of the child within the allocation of the AspectFrame. This ranges from 0.0 (top aligned) to 1.0 (bottom aligned)

-> Float

ratio: The desired aspect ratio.

-> Bool

obeyChild: If True, ratio is ignored, and the aspect ratio is taken from the requistion of the child.

-> m AspectFrame

Returns: the new AspectFrame.

Create a new AspectFrame.
