= class Gtk::AspectFrame
The Gtk::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. 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.
- == Super Class
- * Gtk::Frame
+ == Object Hierarchy
+ * Object
+ * GLib::Instantiatable
+ * GLib::Object
+ * Gtk::Object
+ * Gtk::Widget
+ * Gtk::Container
+ * Gtk::Bin
+ * Gtk::Frame
+ * Gtk::AspectFrame
== Class Methods
--- Gtk::AspectFrame.new(label, xalign, yalign, ratio, obey_child)
Create a new Gtk::AspectFrame.
* label: Label text.
* xalign: Horizontal alignment of the child within the allocation of the Gtk::AspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned)
* yalign: Vertical alignment of the child within the allocation of the Gtk::AspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right 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 Gtk::AspectFrame.
== Instance Methods
--- set(xalign, yalign, ratio, obey_child)
Set parameters for an existing Gtk::AspectFrame.
* xalign: Horizontal alignment of the child within the allocation of the Gtk::AspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned)
* yalign: Vertical alignment of the child within the allocation of the Gtk::AspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right 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: self
--- obey_child?
Gets the current obey_child value.
* Returns: The current obey_child value.
--- obey_child=(obey_child)
Sets the obey_child value.
* obey_child: true or false
* Returns: obey_child
--- set_obey_child(obey_child)
Same as obey_child=.
* obey_child: true or false
* Returns: self
--- ratio
Gets the current ratio.
* Returns: The current ratio value.
--- ratio=(ratio)
Sets the ratio value.
* ratio: The desired aspect ratio.
* Returns: ratio
--- set_ratio(ratio)
Same as ratio=.
* ratio: The desired aspect ratio
* Returns: self
--- xalign
Gets the current xalign.
* Returns: The current xalign value
--- xalign=(xalign)
Sets the horizontal alignment of the child within the allocation of the Gtk::AspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned).
* xalign: The xalign value
* Returns: xalign
--- set_xalign(xalign)
Same as xalign=(xalign).
* xalign: The xalign value
* Returns: self
--- yalign
Gets the current yalign.
* Returns: The current yalign value
--- yalign=(yalign)
Sets the vertical alignment of the child within the allocation of the Gtk::AspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned)
* yalign: The xalign value
* Returns: yalign
--- set_yalign(yalign)
Same as yalign=(yalign)
* yalign: The xalign value
* Returns: yalign
+ == Properties
+ --- obey-child: true or false (Read/Write)
+ Force aspect ratio to match that of the frame's child
+
+ --- ratio: Float (Read/Write)
+ Aspect ratio if obey_child is FALSE
+
+ --- xalign: Float (Read/Write)
+ X alignment of the child
+
+ --- yalign: Float (Read/Write)
+ Y alignment of the child
