Hello there,

i have a problem with dynamically calculating the size of a SWT composite which contains a StyledText widget. The widget has wordWrap on and the text inside it is basically a single line text. My problem is that i cant find a good way to recalculate the composite's height (as precisely as possible) so that the whole text of the widget is visible. i used GC's getAverageCharWidth but it doesnt seem to work that good... on widgets with less text it still cuts a little from bellow and with widgets with a lot of text there is still empty space below.
Can anyone help me find a good way for achieving my goal?

thanks and best regards

Hi,

Here is an example of Text widget that grows/shrinks as its content changes . Same should work fine with Styled Text.

Please note that this is not the right place for SWT related questions, they should be asked in the SWT newsgroup.

HTH,
