Description

A frame that constrains its child to a particular aspect ratio

Arguments

Methods and Functions

Interfaces

GtkAspectFrame implements AtkImplementorIface and GtkBuildable.

Detailed Description

The GtkAspectFrame 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. GtkAspectFrame derives from GtkFrame, so it can draw a label and a frame around the child. The frame will be "shrink-wrapped" to the size of the child.

Structures

Convenient Construction

gtkAspectFrame is the equivalent of gtkAspectFrameNew.

Properties

obey-child [logical : Read / Write]
Force aspect ratio to match that of the frame's child. Default value: TRUE
ratio [numeric : Read / Write]
Aspect ratio if obey_child is FALSE. Allowed values: [0.0001,10000] Default value: 1
xalign [numeric : Read / Write]
X alignment of the child. Allowed values: [0,1] Default value: 0.5
yalign [numeric : Read / Write]
Y alignment of the child. Allowed values: [0,1] Default value: 0.5
