Description

The gtk.AspectFrame packs 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. gtk.AspectFrame derives from gtk.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.

The aspect frame "ratio" property determines the widget width:height ratio. An aspect ratio of 0.5 means the width is one half the height; an aspect ratio of 2.0 means the width is twice the height. The default value for the "ratio" property is 1.0.

The align properties are used to place the child widget within the available area by specifying the fraction of free space (space in the aspect frame that is not used by the child widget) that is placed above or to the left of the child widget. The values range from 0.0 (meaning no free space above or to the left of the child) to 1.0 (meaning all free space above or to the left of the child) . The default value for both align properties is 0.5.

If the "obey-child" property is TRUE (the default value), the "ratio" property is ignored and the aspect ratio is set by the child widget.

Constructor

    gtk.AspectFrame(label=None, xalign=0.5, yalign=0.5, ratio=1.0, obey_child=TRUE)

Creates a new aspect frame object with the specified label, xalign and yalign values. The default values are: label, None; xalign, 0.5; and, yalign, 0.5. If obey_child is TRUE the ratio value is ignored. If obey_child is FALSE, ratio sets the aspect ratio for the child widget. The default value for ratio is 1.0. The default value for obey_child is TRUE.

Methods

    def set(xalign=0.0, yalign=0.0, ratio=1.0, obey_child=TRUE)
