Are there any libraries or functions I can use to determine if an string will fit entirely inside a label?

I hate to cut off a good post as shown in post#2, but this link will probably do it for you in case the previous does not fit your bill. Using the CustomView AutoTextSizeLabel class:

I have usedit and it worked for me.

Thanks for the replies. I've looked at those however and I'm not sure they are the answer.

The measureText routine is just for single lines. The AutoTextSizeLabel is going to alter the size of my text (and possibly also only handles one line) which I don't want.

I'm trying to just find out a way that tells me if some of the text in the label is not visible because it can't fit in the label. I want to then alter that text, taking off all the text that can't fit in and replace it with ... so that it indicates to the user there is more text to read.

I suppose a scrollview would be an alternative to avoid text being cut off, but I'm not sure I want that.

The MeasureText and StringUtils.MeasureMultilineText methods are the answer, you will need to write a routine that can give you a max number of characters based on label width/height in the current font and point size. Once you have that you can trim the text to fit the space.

The only other alternative would be to set the label to single-line and make it MARQUEE style.
