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 TRUE, ratio is ignored, and the aspect
ratio is taken from the requistion of the child.
|
| Returns : | the new GtkAspectFrame. |
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 : |
a GtkAspectFrame |
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 TRUE, ratio is ignored, and the aspect
ratio is taken from the requistion of the child.
