How we can set tooltip of the desired width with multiple lines in a button?
If the length of tooltip text exceeds the given width the remaining tooltip text will be displayed in the next line, instead of displaying the whole text in single line.
So... you want to prevent a line break?
First of all, notice that long lines of text are hard to read, especially on a screen. I normally find myself manually breaking tooltip texts as they appear too long for my taste.
Then: you can use rich text. You might try to use a <span> element around your non-breaking line.
No, i want the multiple lines but according to width i give. I mean each line should be of the given width.
Maybe this will work:
QString toolTipText =
"<nobr>A short line</nobr><br/>"
"<nobr>This is a much longer line than the first</nobr>";
I don't understand your last comment:

What do you want to do? Do you want to set the width of the tooltip manually? Sometimes it's hard to describe something in text, an image with a screenshot of the current situation and a scribble how you want it to look like would be helpful in this case.
