annotate scripts/plot/private/__fltk_ginput__.m @ 13703:22ce748da25f
Add missing UI objects: uicontextmenu, uitoolbar, uipushtool and uitoggletool.
* graphics.h.in (uicontextmenu, uitoolbar, uipushtool, uitoggletool): New
graphic object classes.
(uicontrol::properties::cdata): Allow "single" and "uint8" data.
* graphics.cc (uitoolbar): New class implementation.
* gl-render.cc (opengl_renderer::draw): Skip new object types.
* plot/private/__uiobject_split_args__.m: Don't use varargin. Add parent_type
and use_gcf arguments. Check that number of arguments is a multiple of 2.
* plot/uicontrol.m: Adapt call to __uiobject_split_args__.
* plot/uipanel.m: Likewise.
* plot/uimenu.m: Rewrite to use __uiobject_split_args__.
* plot/uicontextmenu.m: New file.
* plot/uitoolbar.m: Likewise.
* plot/uipushtool.m: Likewise.
* plot/uitoggletool.m: Likewise.
