Hi,
I'm in the process of writing the gtk+ search/replace dialog, and have
hit a problem which has frustrated me for some hours. I'm not too
experienced with C++ (as opposed to C), so forgive me if I'm missing
something obvious.
typeid is reporting the return type of bcview() in GSearch to be
N3lyx8frontend8xformsBCE, which I assume is the name-mangled version of
something related to xforms. However, a similar test in GMathPanel
gives N3lyx8frontend3GBCE which is more correct (GBC being the Gtk-ified
GuiBC).
This is causing segfaults along the lines of:
#0 0x4096e206 in fl_activate_composite () from
/usr/X11R6/lib/libforms.so.1
#1 0x4099a09c in fl_activate_object () from
/usr/X11R6/lib/libforms.so.1
#2 0x082ab012 in lyx::frontend::setEnabled (ob=0x8714758)
at xforms_helpers.C:99
#3 0x082aa4db in lyx::frontend::xformsBC::setWidgetEnabled
(this=0x86e3c80,
obj=0x29) at xformsBC.C:40
#4 0x082aab3b in lyx::frontend::GuiBC<flobjs_,
flobjs_>::refreshReadOnly (
this=0x86e3c80) at stl_list.h:167
#5 0x08301409 in lyx::frontend::ButtonController::readOnly
(this=0x86f1298,
ro=false) at ButtonController.C:113
#6 0x082f5a84 in lyx::frontend::Dialog::show (this=0x86dd818,
[EMAIL PROTECTED]) at Dialog.h:82
So it's segfaulting because it's trying to feed xforms my gtk+ objects.
GSearch code attached, which doesn't even mention any xforms stuff
whatever.
For contrast (or lack thereof) my class is:
class GSearch : public GViewCB<ControlSearch, GViewGladeB>
Where the (working) MathPanel is:
class GMathPanel : public GViewCB<ControlMath, GViewGladeB>
I just can't find what I'm doing differently to cause this problem.
Any hints appreciated.
John
