GtkLayout is similar to GtkDrawingArea in that it’s a “blank slate” and doesn’t do anything but paint a blank background by default. It's different in that it supports scrolling natively (you can add it to a GtkScrolledWindow), and it can contain child widgets, since it’s a GtkContainer. However if you’re just going to draw, a GtkDrawingArea is a better choice since it has lower overhead.
When handling expose events on a GtkLayout, you must draw to GTK_LAYOUT (layout)->bin_window, rather than to GTK_WIDGET (layout)->window, as you would for a drawing area.
GtkWidget * gtk_layout_new (GtkAdjustment *hadjustment,GtkAdjustment *vadjustment);
Creates a new GtkLayout. Unless you have a specific adjustment
you’d like the layout to use for scrolling, pass NULL for
hadjustment
 and vadjustment
.
void gtk_layout_put (GtkLayout *layout,GtkWidget *child_widget,gint x,gint y);
Adds child_widget
 to layout
, at position (x
,y
).
layout
 becomes the new parent container of child_widget
.
void gtk_layout_move (GtkLayout *layout,GtkWidget *child_widget,gint x,gint y);
Moves a current child of layout
 to a new position.
void gtk_layout_set_size (GtkLayout *layout,guint width,guint height);
Sets the size of the scrollable area of the layout.
void gtk_layout_get_size (GtkLayout *layout,guint *width,guint *height);
Gets the size that has been set on the layout, and that determines
the total extents of the layout’s scrollbar area. See
gtk_layout_set_size().
GtkAdjustment *
gtk_layout_get_hadjustment (GtkLayout *layout);
gtk_layout_get_hadjustment has been deprecated since version 3.0 and should not be used in newly-written code.
This function should only be called after the layout has been
placed in a GtkScrolledWindow or otherwise configured for
scrolling. It returns the GtkAdjustment used for communication
between the horizontal scrollbar and layout
.
See GtkScrolledWindow, GtkScrollbar, GtkAdjustment for details.
GtkAdjustment *
gtk_layout_get_vadjustment (GtkLayout *layout);
gtk_layout_get_vadjustment has been deprecated since version 3.0 and should not be used in newly-written code.
This function should only be called after the layout has been
placed in a GtkScrolledWindow or otherwise configured for
scrolling. It returns the GtkAdjustment used for communication
between the vertical scrollbar and layout
.
See GtkScrolledWindow, GtkScrollbar, GtkAdjustment for details.
void gtk_layout_set_hadjustment (GtkLayout *layout,GtkAdjustment *adjustment);
gtk_layout_set_hadjustment has been deprecated since version 3.0 and should not be used in newly-written code.
Sets the horizontal scroll adjustment for the layout.
See GtkScrolledWindow, GtkScrollbar, GtkAdjustment for details.
void gtk_layout_set_vadjustment (GtkLayout *layout,GtkAdjustment *adjustment);
gtk_layout_set_vadjustment has been deprecated since version 3.0 and should not be used in newly-written code.
Sets the vertical scroll adjustment for the layout.
See GtkScrolledWindow, GtkScrollbar, GtkAdjustment for details.
