I admit freely I’m floundering around but… I’m trying to write a desktop application for the IIgs in C to set flagstones, borrowing heavily from Mike Westerfield’s “Toolbox Programming in C”. In the course of that endeavor I’ve gone a bit
far afield trying to output printf statements to a desktop window that I can scroll through and copy and paste to save or whatever, basically a console window I guess. I’ve had some success starting up the tools with Orca’s startdesk(); , setting
the grafport and calling printf() but I wanted to use TextEdit and so switched to StartUpTools and have had much less success.
I’ve tried creating a buffer of CStrings:
void initbfr(void)
{
int i;
int numstrs, strlen;
numstrs = 300;
strlen = 80;
outbfr.indx = 0;
outbfr.outstrs = malloc(numstrs * sizeof(char*));
for(i = 0; i < numstrs; i++)
{
outbfr.outstrs[i] = malloc((strlen) * sizeof(char));
}
…
and to open a window:
void DoOut(void)
{
outwinptr = outwin();
SetPort(outwinptr);
setCtrl();
}
GrafPortPtr outwin(void)
{
return NewWindow2("\pOutput", 0, Output, NULL, 0x02, teControl, rWindParam1);
}
void Output(void)
{
DrawControls(GetPort());
}
And in setCtrl():
void setCtrl(void)
{
LongWord length;
LongWord *tPtr, *sPtr;
FontID fID;
TEStyle style;
fID.fidRec.fontStyle = 0;
style.styleFontID = fID;
/* length = 42; /* hard-coded length outbfr.outstrs[0] */
length = 300; /* hard-coded size of buffer */
/* tPtr = (LongWord *) ((outbfr.outstrs[0])); */
tPtr = (LongWord *) ((LongWord)(*(outbfr.outstrs)));
tPtr = (LongWord *) (&outbfr);
sPtr = (LongWord *) &style;
TESetText(5, (Ref) tPtr, length, 0,(Ref) NULL, NULL);
/* TESetText(1, (Ref) tPtr, length, 0,(Ref) NULL, NULL); */
/* TESetText(5, (Ref) tPtr, length, 0,(Ref) sPtr, NULL); */
}
I don’t know if I need to create a style record and a TERecord. or what not. I know it’s a big ask but I put a SHK on github containing the files and a file “mk” to compile it if anyone might look and tell me what a banana I am and point me in
the right direction.
I don’t know of anyone programming Apple IIs around here to talk to. Anyway the repository is at:
https://github.com/mswade0/Output.git
if anyone is so inclined, again a big ask, I know.
