Question How to do Text Wrapping for text in List Field with Checkboxes ?

Please Login to Remove!

Hi all,

I m creating a ListField with Checkboxes from How To - Create a ListField with check boxes

But I m not getting how to wrap Text in a row in that ListField.

I referred the thread Text Wrapping for text in List Field items

Here its written as

Code:
If all you are displaying is text, then I would go with the approach suggested by rab.
I m displaying Text only in ListField which I want to wrap if it doesnt fit within device screen.

But i m not getting "approach suggested by rab" in which How to calculate?

Code:
String [] linesToDraw = calculate the number of lines depending on the row width
I m stucked at this so any details on this issue ?

Default

You can retrieve the width of you text ahead of time using Font.getAdvance(String text)

See the API Docs.

You would then calculate how may lines you need to display the text, and size the row accordingly.

Question

I got the no. of lines properly according to row width & stored it in a Vector & i m doing

Code:
int fontHeight = this.getFont().getHeight();

         for (int i = 0; i < linesToDraw .size(); i++)
        {           
            textToDraw = (String)linesToDraw.elementAt(i);
            graphics.drawText(textToDraw, xpos, ypos, 0 , width);
            ypos += fontHeight;
        }
now its drawing the lines but over the previous one as by default listField.setRowHeight() is taking only one row. If there r 2 rows then I write setRowHeight(getFont().getHeight()*2) in drawListRow() but then it goes in loop.

If I write setRowHeight() while creating ListField then it comes properly but for all rows same row height is set.

I gets the String to draw at Runtime & the row height should be variable for different rows then how can I setRowHeight() with what parameter & in which method ?
