Hi,

is there any way in SWT to ignore accelerators that are set to the Shell's
Menu in case they are written into a Text field?

For example, have an accelerator "Shift-C" does the action "Open File...".
Now, when focus is set to a Text Field, I would like to have the native
"Copy" action being performed instead of the parent / Shell's action. Or
for example an accelerator "N" for "Goto next news", would stop the Text
widget of containing any "n"-Character.

The Text widget should keep and use those keys that are consumable, and
pass any others to parent Widgets and Controls.

Found a bug entry (19527
https://bugs.eclipse.org/bugs/show_bug.cgi?id=19527) that deals with this
problem, but it was set to "Wontfix" since Eclipse now offers
Editor/Content dependant key bindings (e.g. "In Java Source"). But thats
no solution for other applications that use SWT without the Eclipe
Framework.

For 3.0, SWT provided a filtering mechanism on Display (i.e.,
Display.addFilter()). This filtering mechanism is then used by Platform UI
to provide key bindings in Eclipse. We no longer use menu accelerators,
and so are capable of providing the support you mention.

You can either try to integrate the Eclipse key binding mechanism into your
SWT application, or just rip off sections of code you need. Look at
WorkbenchKeyboard in the "org.eclipse.ui.workbench" for an example of how
to do this.
