I'm having problems with the panel_each_item,panel_end_each macros. I've
tried both the macros and writing out the code to accomplish the same
thing. I produce an executable so not including .h files is not the
problem.
I'm using oregon's C++ compiler on a Sun 3/80. All the sunview functions
are declared with C linkage and are called by member functions of C++
classes or as simple non-member functions.
Here's the error message from dbxtool:
signal SEGV (segmentation violation) in panel_get at 0xbaf78
panel_get+0x22: movl a0@(0x24),a0
The Sunview routine (with the explicit code written out) follows:
void remove_item_with_label(pn,label)
Panel pn;
char* label;
{
Panel_item pi;
char* get_window_name();
*** dbxtool points at the line below ***
==> for(pi=(Panel_item)panel_get(pn,PANEL_FIRST_ITEM);pi;
pi=(Panel_item)panel_get(pn,PANEL_NEXT_ITEM))
{
if(!strncmp((char*)panel_get(pi,PANEL_CLIENT_DATA),label,strlen(label)))
{
/* found button */
panel_set(pi,PANEL_SHOW_ITEM,FALSE,0);
panel_destroy_item(pi);
return;
}
}
}
A "dump" command produces the following:
label = 0x1fba58 "rtg"
pi = 0x1fcd10 ""
pn = 0x1fba44 "rtg"
A "where" command produces:
