measureText is implemented by UIComponent and will give you the correct size of the text.

I am mul! tiplying it by 10 to caluculate the width of a particular column. If i am not doing this ( multiplying by 10) .. Grid col names are not displayed properly. --- In [email protected] <mailto:flexcomponents%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > At init time, the size of the DG is not known so you get to dictate it > with the column widths, then all columns get resized proportionally. > After that it is sort of locked in so columns sizes are honored except > those at the end that will get squished to fit.
