Method
GtkWidgetchild_focus
Declaration [src]
gboolean
gtk_widget_child_focus (
GtkWidget* widget,
GtkDirectionType direction
)
Description [src]
Called by widgets as the user moves around the window using keyboard shortcuts.
The direction argument indicates what kind of motion is taking
place (up, down, left, right, tab forward, tab backward).
This function calls the Gtk.WidgetClass.focus virtual function;
widgets can override the virtual function in order to implement
appropriate focus behavior.
The default focus() virtual function for a widget should return
true if moving in direction left the focus on a focusable location
inside that widget, and false if moving in direction moved the focus
outside the widget. When returning true, widgets normally call
gtk_widget_grab_focus() to place the focus accordingly;
when returning false, they don’t modify the current focus location.
This function is used by custom widget implementations; if you’re
writing an app, you’d use gtk_widget_grab_focus() to move
the focus to a particular widget.
Parameters
direction-
Type:
GtkDirectionTypeDirection of focus movement.
