DrawString / Ellipsis / word gaps problem

VisualHint

12/21/2004 3:02:00 PM

Hi,

another very strange behaviour with ellpisis and the DrawString method.
If I display the string "This is a string" with no ellipsis, there is a
certain gap between words. Let's say 6 pixels between "This" and "is".
If the bounding rectangle is smaller and ellipsis appear, the gap
between thoses 2 words becomes 5 pixels. If I make the rectangle even
smaller, the gap becomes 4 pixels.

It means that while the user is resizing the bounding rectangle, the
string is displayed like shaking because of this changing gap between
words.

Did I miss something ? Is it a normal new behaviour in the way GDI+
works, or does it have simply a bug ?

Thanks for your help

Just a guess, but it sounds like the text is being displayed as left and
right justified.

hummm, no, here is the format used:

StringFormat drawFormat = new StringFormat();
drawFormat.Alignment = StringAlignment.Near;
Visually, it is left justified.

I should add that this is this combination that doesn't work properly:

StringFormat drawFormat = new StringFormat();
drawFormat.Alignment = StringAlignment.Near;
drawFormat.FormatFlags = StringFormatFlags.NoWrap;
drawFormat.LineAlignment = StringAlignment.Center;
drawFormat.Trimming = StringTrimming.EllipsisCharacter;

Near is needed for left justification
NoWrap is needed so that I don't see the words going on a second line
Center is needed for a vertical center effect
and I need ellipsis

Any idea ?

I would try it without the "drawFormat.LineAlignment =
StringAlignment.Center;" and see if it makes a difference with your spacing
problem.

You can trust me, I tried a lot of combinations...
Unwrapped text + ellipsis seems to be the problem.
I think there is a bug in the way ellipsis are handled in this case. I
even saw the gaps between some letters change. Could someone from
Microsoft confirm or share thoughts ?
