gnomemm | libgnomecanvasmm | Ver: 2.6
Summary: Method "Gnome::Canvas::Bpath::set_bpath" seems partia=
lly
broken...
Product: gnomemm
Version: 2.6
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: libgnomecanvasmm

Please describe the problem:
When recompiling code with the new version of the library (which worked w=
ith the
last version), a message appears every time the program does a "set_bpath=
":
(main:XXXX): GLib-GObject-WARNING **: unable to set property `bpath' of t=
ype
`GnomeCanvasPathDef' from value of type `gpointer'
Also, due to this, no output is drawn for the objects involved... ;)
Steps to reproduce:
Supposedly simply using "set_bpath" in a Bpath object from a parameter of=
type:
Glib::RefPtr<Gnome::Canvas::PathDef>
The piece of code in my case is:
Glib::RefPtr<Gnome::Canvas::PathDef> pathdef =3D Gnome::Canvas::PathDef::=
create();
...
pathdef->moveto(p.x,p.y);
for (uint n=3D0;n<=3DSAMPLES;n++) {
...
pathdef->lineto(p.x,p.y);
}
_segments[k]->set_bpath(pathdef);
Actual results:
Expected results:
Nothing is said, and the objects are drawn
Does this happen every time?
Yes.
Other information:
The issue can be resolved (in quite a dirty way, actually) putting code l=
ike
this, which actually uses directly the C API of libgnomecanvas:
GnomeCanvasPathDef* pathdef =3D gnome_canvas_path_def_new();
...
gnome_canvas_path_def_moveto(pathdef, p.x, p.y);
for (uint n=3D0;n<=3DSAMPLES;n++) {
...
gnome_canvas_path_def_lineto(pathdef, p.x, p.y);
}
...
GnomeCanvasBpath* c_obj =3D _segments[k]->gobj();
gnome_canvas_item_set(GNOME_CANVAS_ITEM(c_obj), "bpath", pathdef, NULL);
I took this code from om-synth (CVS), since the matter arose in a compila=
tion of
their code (found searching google: "unable bpath GnomeCanvasPathDef").
