Hi experts

I am trying to get familiar with this commands from Eclipse 3.3

I know how to create a command, handle return values and so but I don't
know how to set a parameter for a command.

I defined my command as follows
------------------------------------
<command

defaultHandler=" toolseye.vehiclemanagement.actions.DeleteVehicleCommandHandl er "
description="Action to delete a selection of Vehicles"
id="toolseye.vehiclemanagement.deleteVehicleCommand"
name="toolseye.vehiclemanagement.deleteVehicleCommand">
<commandParameter

id=" toolseye.vehiclemanagement.deleteVehicleCommand.selectionPar am "
name="Selection"
optional="false"
values="org.eclipse.jface.viewers.IStructuredSelection">
</commandParameter>
</command>
------------------------------------

My problem is, that I can't find any method where I can set the value
for my IStructuredSelection?

Thx
-- Marc

It's not that kind of parameter, it tends to be more static information.
For example a toggle context command, where you create a Toggle
Context1 button and a Toggle Context2 button. Context1 and Context2 fit
well with the command parameterization scheme.

For the selection, you can use HandlerUtil.getCurrentSelection(event) to
get the current selection within your handler execute(*) method. Before
3.3 you could extract the current selection using the
event.getApplicationContext() and an ISources constant.

Subclass org.eclipse.core.commands.AbstractHandler if you have the option.

Later,

Wow, sounds difficult and I don't get it ^^

In my case the selection comes from a ListViewer. The view containing
this viewer executes the command and my problem now is how to tell the
command which elements are selected?

Thanks again
