Hi,
I'm newbie in SWT. And I want to write on a label something like this:
"Visit my website", "website" is a link, and i would like that to be
as a comun link in html, text undreline and in blue, or other color. And
then with Program execute the default browser of the OS. Any idea?? does
SWT support html as swing??
Thanks,
Mariano Vicario
PD: any idea how can i minimze to systemtray???
