Package: Aspect_Frame

Description

package Gtk.Aspect_Frame is

A Gtk_Aspect_Frame is the same type of widget as a frame, but it constrains its child to a specific aspect ratio between its width and its height.

This ratio can either be given explicitly by the user, or chosen from the widget's initial size request (might be different from the one if was actually given).

Binding from C File version 2.8.17

Types

Gtk_Aspect_Frame

type Gtk_Aspect_Frame is access all Gtk_Aspect_Frame_Record'Class;

Constants & Global variables

Subprograms & Entries

Gtk_New

procedure Gtk_New 
(Aspect_Frame: out Gtk_Aspect_Frame;
Label: UTF8_String;
Xalign: Gfloat;
Yalign: Gfloat;
Ratio: Gfloat;
Obey_Child: Boolean);
Create a new Aspect_Frame. If Label is the empty string, then the frame won't have any title. Xalign and Yalign are constrained to the range 0.0 .. 1.0 and specify the alignment of the child inside the frame (0.0 means either left or top aligned, 1.0 means right or bottom aligned). Ratio is the ratio width/height for the child of the frame. If Obey_Child is True, then Ratio is ignored and the effective ratio is taken from the child's requisition (ie the ideal size it asked for at creation time).

Initialize

procedure Initialize 
(Aspect_Frame: access Gtk_Aspect_Frame_Record'Class;
Label: UTF8_String;
Xalign: Gfloat;
Yalign: Gfloat;
Ratio: Gfloat;
Obey_Child: Boolean);
Internal initialization function. See the section "Creating your own widgets" in the documentation.

Get_Type

function Get_Type return Gtk.Gtk_Type;
Return the internal value associated with a Gtk_Aspect_Frame.

Set

procedure Set 
(Aspect_Frame: access Gtk_Aspect_Frame_Record;
Xalign: Gfloat;
Yalign: Gfloat;
Ratio: Gfloat;
Obey_Child: Boolean);
Modify the frame's parameters (see the description of these parameters for Gtk_New.

Get_Ratio

function Get_Ratio 
(Aspect_Frame: access Gtk_Aspect_Frame_Record) return Gfloat;
Return the current ratio for the frame (width / height)

Get_Xalign

function Get_Xalign 
(Aspect_Frame: access Gtk_Aspect_Frame_Record) return Gfloat;
Return the current X alignment for the frame. 0.0 means the child is left aligned, 1.0 that it is right aligned.

Get_Yalign

function Get_Yalign 
(Aspect_Frame: access Gtk_Aspect_Frame_Record) return Gfloat;
Return the current Y alignment for the frame. 1.0 means the child is top aligned, 1.0 that it is bottom aligned.
