Comment(by stippi):
If you couldn't find the TruncateString() method being used in drawing
code, then that's most likely the issue. You have to know that BMenuFields
internally use a BMenuBar, which is a subclass of BMenu. The rendering of
the label is done using BMenuItem drawing code. Usually, a menu uses as
much space as it needs on the screen, so that's probably why the string
truncation is missing. In BMenuItem, there should be code similar to
DrawString(Label(), ...);. This needs to change to:
{{{
BString truncatedLabel(Label());
font.TruncateString(&truncatedLabel, ...);
DrawString(truncatedLabel.String(), ...);
}}}
... with the availabel width passed to font.TruncateString(). If there
isn't already the font variable around, then you can get it via
Menu()->GetFont(&font). But to do this in every BMenuItem (if it isn't
already done) is a small performance problem.
