Button Boxes
Button Boxes are a convenient way to quickly layout a group of buttons. They come in both horizontal and vertical flavours. You create a new Button Box with one of the following calls, which create a horizontal or vertical box, respectively:
GtkWidget *gtk_hbutton_box_new( void ); GtkWidget *gtk_vbutton_box_new( void ); |
Buttons are added to a Button Box using the usual function:
gtk_container_add (GTK_CONTAINER (button_box), child_widget); |
Here's an example that illustrates all the different layout settings for Button Boxes.
#include <gtk/gtk.h>
/* Create a Button Box with the specified parameters */
static GtkWidget *create_bbox( gint horizontal,
char *title,
gint spacing,
gint child_w,
gint child_h,
gint layout )
{
GtkWidget *frame;
GtkWidget *bbox;
GtkWidget *button;
frame = gtk_frame_new (title);
if (horizontal)
bbox = gtk_hbutton_box_new ();
else
bbox = gtk_vbutton_box_new ();
gtk_container_set_border_width (GTK_CONTAINER (bbox), 5);
gtk_container_add (GTK_CONTAINER (frame), bbox);
/* Set the appearance of the Button Box */
gtk_button_box_set_layout (GTK_BUTTON_BOX (bbox), layout);
gtk_box_set_spacing (GTK_BOX (bbox), spacing);
/*gtk_button_box_set_child_size (GTK_BUTTON_BOX (bbox), child_w, child_h);*/
button = gtk_button_new_from_stock (GTK_STOCK_OK);
gtk_container_add (GTK_CONTAINER (bbox), button);
button = gtk_button_new_from_stock (GTK_STOCK_CANCEL);
gtk_container_add (GTK_CONTAINER (bbox), button);
button = gtk_button_new_from_stock (GTK_STOCK_HELP);
gtk_container_add (GTK_CONTAINER (bbox), button);
return frame;
