Hey,
I'm working with IV 3.1-beta.
I've a class with a TBScrollBox (TextShow).
For this class I've defined the following function:
class TextShow : public InputHandler {
....
....
protected:
TBScollbox* box;
....
}
inline void TextShow::scroll_to_end()
{ box->scroll_to(Dimension_Y, Coord(0)); }
My problem is that I receive always:
signal SEGV (no mapping at the fault address) in allocate__7ivPatchFP8ivCanvasRC12ivAllocationR11ivExtension at 0xf766b0f0
allocate__7ivPatchFP8ivCanvasRC12ivAllocationR11ivExtension+0x34: ld [%o1 + 4], %o2
(xdbx) where
allocate__7ivPatchFP8ivCanvasRC12ivAllocationR11ivExtension() at 0xf766b0f0
reallocate__17ivTBScrollBoxImplFv() at 0xf76871c8
refresh__17ivTBScrollBoxImplFv() at 0xf7686eec
impl__13ivTBScrollBoxCFv() at 0xf7686ce0
scroll_to__13ivTBScrollBoxFUif() at 0xf7686bec
scroll_to_end__8TextShowFv(__0this = 0xe9208), line 469 in "xrapiv/rapiv.c"
this error, if I call scroll_to_end and the window where I want to scoll
my text, is iconified.
I don't want to test it (if the window is mapped) always
and I think it isn't normal, but I don't know my fault.
Perhaps it's a bug ???
Thanks in advance,
Joerg (ringel@forwiss.uni-passau.de)
