Summary: autoSizeColumn() works incorrectly for large widths (cf.
bug #43090)
Product: POI
Version: 3.0-dev
Platform: PC
OS/Version: Windows Server 2003
Status: NEW
Severity: normal
Priority: P2
Component: HSSF
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Preliminary note: This bug is in 3.1-FINAL, but the latest version the Combo
Box did offer was 3.0-dev
In HSSFSheet.autoSizeColumns(), the following code:
if (width != -1) {
if (width > Short.MAX_VALUE) { //width can be bigger that Short.MAX_VALUE!
width = Short.MAX_VALUE;
}
sheet.setColumnWidth(column, (short) (width * 256));
}
should be replaced by:
if (width != -1) {
width *= 256;
if (width > Short.MAX_VALUE) { //width can be bigger that Short.MAX_VALUE!
width = Short.MAX_VALUE;
}
sheet.setColumnWidth(column, (short) (width));
}
which is probably what was intended, since only then the cast to short will
always have an argument that is within range.
With the original version, large widths produce settings which depend on the
least significant bits and thus tend to be rather random.
The topic has already be addressed in bug #43090, but the resolution which made
it into the final version does not solve the problem.
