Re: [platform-swt-dev] StyledText and keyboard actions

[Thomas Singer <ts-swt@xxxxxxxxxxx>]

Hi Leo,

But the main question is how to tell setKeyBinding what own code should 
be executed? If I recall correctly, Swing used Actions for that, but 
here a simple Runnable would do as well.

How exactly Eclipse injects own shortcuts - assuming that StyledText is 
the core control for the code editor?
