Question

This one is for all the TextField wizards out there. I have a text field that displays 2 paragraphs of texts. The first one I want to be truncated to show only 3 lines of text maximum. The 2nd paragraph is to be appended to that text.

Is there a way I can show only the first 3 lines of the first paragraph? Think of it like an abstract for an article for the first paragraph.

I tried doing it with String.subStr(0, guestimate of 3 lines of chars) but it’s pretty inconsistent in that some strings will take up 4 lines of the textfield.

I thought about doing 2 separate textfields but in the case of the first paragraph having only 1 line worth of chars, there will be gap of 2 lines worth of chars between the 2nd paragraph.

Answer 1

Have a look at TextField#getLineOffset(). It will return the character index of the first character on the specified line – you can use substr or substring to truncate the text accordingly.
