Detailed Description

A frame that constrains its child to a particular aspect ratio.

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. Because it derives from Gtk::Frame, it can draw a label and a frame around the child. The frame will be "shrink-wrapped" to the size of the child.

Constructor & Destructor Documentation

virtual Gtk::AspectFrame::~AspectFrame

(

)

[virtual]

Gtk::AspectFrame::AspectFrame	(	const Glib::ustring &	label = Glib::ustring(),
		Align	xalign = Gtk::ALIGN_CENTER,
		Align	yalign = Gtk::ALIGN_CENTER,
		float	ratio = 1.0,
		bool	obey_child = false
	)		[explicit]

Constructor to create a new AspectFrame object.

Parameters:

label	Label text.
xalign	Horizontal alignment of the child within the allocation of this AspectFrame. For possible values, see Gtk::Align.
yalign	Vertical alignment of the child within the allocation of this AspectFrame. For possible values, see Gtk::Align.
ratio	The desired aspect ratio.
obey_child	If true, ratio is ignored and the aspect ratio is taken from the requisition of the child.

Gtk::AspectFrame::AspectFrame	(	const Glib::ustring &	label,
		float	xalign,
		float	yalign,
		float	ratio = 1.0,
		bool	obey_child = false
	)		[explicit]

Constructor to create a new AspectFrame object.

Parameters:

label	Label text.
xalign	Horizontal alignment of the child within the allocation of this AspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned).
yalign	Vertical alignment of the child within the allocation of this 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 requisition of the child.
