VisuUiShadeCombobox implements AtkImplementorIface, GtkBuildable, GtkCellLayout and GtkCellEditable.
This widget looks like a GtkComboBox and it displays a list of preset colour shades. These patterns are defined by colour parameters, see ToolShade.
This widget can emit a “shade-selected” signal that is a wrapper around the “changed” signal, but it is emitted only when a new shade is selected and this shade is passed to the callback.
GtkWidget * visu_ui_shade_combobox_new (gboolean hasAlphaChannel
,gboolean showNames
);
A VisuUiShadeCombobox widget is like a GtkComboBox widget, but it is already filled
with the known shades. Using this widget
is a convienient way to share shades between all part of V_Sim and to give a consistent
look of all shade selection. If the argument hasAlphaChannel
is FALSE, the widget
display all shades but without their alpha channel, assuming it to be fully opaque.

GdkPixbuf * visu_ui_shade_combobox_getStamp (VisuUiShadeCombobox *shadeComboBox
,ToolShade *shade
);
The shadeComboBox
has little pixbufs to represent the shade. User methods can
use these pixbufs but should considered them read-only.

GdkPixbuf * visu_ui_shade_combobox_buildStamp (ToolShade *shade
,GdkPixbuf *pixbuf
);
This method is used to create pixbuf representing shades. If pixbuf
is given,
it must be a valid pixbuf, and the shade is created in it. Otherwise, a new
pixbuf is created.
