No, there is no function, and it is pretty difficult to get that information by writing your own code.  You could possible estimate the width, by storing the width of each char in your code, and adding up the width of all chars in the string... but it will break if someone resizes the text in their browser.

Create a label

Set the background and foreground colour to your screen's background colour and the font etc to the same as the text you want to measure

Put the label in a horizontal panel

Add the horizontal panel to the root panel

Set the horizontal panel's z index behind everything else

Put the text in the label

Read the width with getOffsetWidth()
