Re: [platform-swt-dev] Desktop font size effects swt layout

Hi Kelly,

The adoption of the OS-specified fonts
by the SWT Controls is correct.  Invoking setFont() on each Control
should change their fonts accordingly, but there are various reasons that
this is not the suggested approach to take.

Your use of SWT layouts should insulate
you from variations like font size, assuming that you aren't hard-coding
sizes/positions that should be left to compute their own optimal values.
 Proper use of SWT Layouts should enable widget layouts to adapt not
only to variations like font size, but also across platforms where the
available fonts and widget sizing characteristics can differ significantly.

Without seeing example code snippets
it's difficult to know why your use of layouts isn't doing this for you.
 It may be worth having a look at http://www.eclipse.org/articles/article.php?file=Article-Understanding-Layouts/index.html
, which describes the ideal uses of Layouts.  There are also various
example Layout snippets at http://www.eclipse.org/swt/snippets/
.

If you these resources don't fully answer
your questions then you can ask further on the SWT forum ( http://www.eclipse.org/forums/index.php?t=thread&frm_id=100
), and if possible provide your own runnable code snippets that demonstrate
your problems.

HTH,
Grant

Desktop font size effects swt layout

Hi

I have looked on Google but can not find answer or I can't word it correctly
to find it.

When I develop a SWT application my computers desktop font size is set
to windows 7 default size.
I use mainly use Form layout with Grid layout for some windows.

My problem is that when the program is run on a windows system and the
user has increased the font size of the desktop my layouts are all messed
up.
If I go into windows settings and reset the font back to the default size
everything looks fine again.

I have tried using setFont on all the widgets but it does not effect this
problem.

What can I do about desktop font size being changed from the default?

Thanks
