make the orientation flipping much simpler by using the GtkOrientable
2009-02-19 Michael Natterer <mitch@imendio.com> * gtk/gtkscalebutton.c: make the orientation flipping much simpler by using the GtkOrientable features of the involved widgets: (gtk_scale_button_init): create the frame, box and scale here, they never need to be recreated because they implement GtkOrientable. (gtk_scale_button_constructor): remove their construction here. (gtk_scale_button_set_orientation): don't destroy and re-create anything. Instead, simply set the orientation of the above created widgets and fiddle a bit with the "plus" and "minus" buttons' packing and the scale's "inverted" state. Remove separate internal GtkScaleButtonHScale and GtkScaleButtonVScale subclasses and simply have a GtkScaleButtonScale directly inherited from GtkScale. svn path=/trunk/; revision=22375

* gtk/gtkscalebutton.c: make the orientation flipping much simpler
|

by using the GtkOrientable features of the involved widgets:
|
||||
|
||||
(gtk_scale_button_init): create the frame, box and scale here,
|
||||
they never need to be recreated because they implement GtkOrientable.
|
||||
|
||||
(gtk_scale_button_constructor): remove their construction here.
|
||||
|

(gtk_scale_button_set_orientation): don't destroy and re-create

anything. Instead, simply set the orientation of the above created
|
||||
widgets and fiddle a bit with the "plus" and "minus" buttons'
|
||||
packing and the scale's "inverted" state.
|
||||
|
||||
Remove separate internal GtkScaleButtonHScale and
|
||||
GtkScaleButtonVScale subclasses and simply have a
|
||||
GtkScaleButtonScale directly inherited from GtkScale.
