The arrow widget
The arrow widget is derived from the misc widget ( GtkMisc)
and is intended for use where a directional arrow (in one of the four
cardinal directions) is desired. As such, it has very limited
functionality and basically only draws itself in a particular direction
and with a particular shadow type. The arrow widget will expand to fill
all the space it is allocated.
- User Option: arrow_type
The ARROW_TYPE option specifies which direction the arrow will
point. It can be one of `GTK_ARROW_UP', `GTK_ARROW_DOWN',
`GTK_ARROW_LEFT' or `GTK_ARROW_RIGHT'. This will set the arrow
pointing in the direction specified.
- User Option: shadow_type
The SHADOW_TYPE option specifies how to draw the shadow for the
arrow. Currently, only the `GTK_SHADOW_IN' and `GTK_SHADOW_OUT'
shadow types are supported for drawing arrows. Other shadow types
will cause nothing to be drawn.
- Function: guint gtk_arrow_get_type (void)
Returns the `GtkArrow' type identifier.
- Function: GtkWidget* gtk_arrow_new (GtkArrowType ARROW_TYPE,
Create a new `GtkArrow' object and initialize it with the values
ARROW_TYPE and SHADOW_TYPE. The new widget is returned as a
pointer to a `GtkWidget' object. `NULL' is returned on failure.
- Function: void gtk_arrow_set (GtkArrow *ARROW, GtkArrowType
ARROW_TYPE, GtkShadowType SHADOW_TYPE)
Set the ARROW_TYPE and SHADOW_TYPE options of an arrow widget. It
is important to not set the fields of the `GtkArrow' structure
directly (or, for that matter, any type derived from `GtkObject').
- Function: GtkArrow* GTK_ARROW (gpointer OBJ)
Cast a generic pointer to `GtkArrow*'. Standard Macros, for
- Function: GtkArrowClass* GTK_ARROW_CLASS (gpointer CLASS)
Cast a generic pointer to `GtkArrowClass*'. Standard
Macros, for more info.
- Function: gint GTK_IS_ARROW (gpointer OBJ)
Determine if a generic pointer refers to a `GtkArrow' object.
