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.
GtkWidget * gtk_aspect_frame_new (const gchar *label,gfloat xalign,gfloat yalign,gfloat ratio,gboolean obey_child);
Create a new GtkAspectFrame.
label |
Label text. |
|
xalign |
Horizontal alignment of the child within the allocation of the GtkAspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned) |
|
yalign |
Vertical alignment of the child within the allocation of the GtkAspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned) |
|
ratio |
The desired aspect ratio. |
|
obey_child |
If |
void gtk_aspect_frame_set (GtkAspectFrame *aspect_frame,gfloat xalign,gfloat yalign,gfloat ratio,gboolean obey_child);
Set parameters for an existing GtkAspectFrame.
aspect_frame |
||
xalign |
Horizontal alignment of the child within the allocation of the GtkAspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned) |
|
yalign |
Vertical alignment of the child within the allocation of the GtkAspectFrame. This ranges from 0.0 (left aligned) to 1.0 (right aligned) |
|
ratio |
The desired aspect ratio. |

obey_child |
If |

Force aspect ratio to match that of the frame's child.
