Thanks Steve and Ken for the replies. Following is a code snippet:
// Set the standard font. Save the current font.
// It is a Pilot convention to not destroy the current font
// but to save and restore it.
currFont = FntSetFont (stdFont);
// Get the record number that corresponds to the table item to draw.
// The record number is stored in the "intValue" field of the item.
recordNum = TblGetItemInt (tableP, row, column);
// Determine the length of barcode that will fit within the bounds
GetCurrentFieldData(recordNum, "Quantity");
width = bounds->extent.x - 2 - FntCharsWidth(FieldDataP,
StrLen(FieldDataP));
textLen = StrLen(GetCurrentFieldData(recordNum, "Barcode"));
FntCharsInWidth(FieldDataP, &width, &textLen, &fits);
// Now draw the barcode from the record
// WinDrawChars(FieldDataP, textLen, bounds->topLeft.x, bounds->topLeft.y);
WinDrawTruncChars((ConstCharPtr)FieldDataP, textLen, bounds->topLeft.x,
bounds->topLeft.y, width);
Some background information:
- GetCurrentFieldData() sets the global pointer FieldDataP and also returns
its value
- FntCharsInWidth() seems to work fine, modifying the width, textLen and
fits variables as needed. Even if I comment out this function and send
WinDrawTruncChars() a calculated value, I still get a Fatal Error (no error
code on the Palm - it just gives a Fatal Error with the option to reset)
- WinDrawChars(), with the same parms (except width, obviously) works fine.
TIA!
