[e4-dev] Programmatically adding a command to a tool item

["Toedter, Kai" <kai.toedter@xxxxxxxxxxx>]

Hi All,

 

I am currently making last preparations for EclipseCon. To get my personal MinMax Addon running I need to bind a command to a tool item (with a parameter). Here is my source:

 

MCommand command = MCommandsFactory.INSTANCE.createCommand();

command.setElementId("com.toedter.e4.ui.workbench.addons.minmax.restore");

command.setCommandName("Restore Stack");

command.setDescription("xxx");

command.setContributorURI("kai");

 

// application.getCommands().add(command);

 

MHandler handler = MCommandsFactory.INSTANCE.createHandler();

handler.setContributionURI("bundleclass://com.toedter.e4.ui.workbench.addons/com.toedter.e4.ui.workbench.addons.minmax.RestoreHandler");

handler.setCommand(command);

// application.getHandlers().add(handler);

 

MHandledToolItem toolItem = MMenuFactory.INSTANCE.createHandledToolItem();

toolItem.setIconURI("platform:/plugin/com.toedter.e4.ui.workbench.addons/icons/fastview_restore.gif");

toolItem.setCommand(command);

 

MParameter parameter = MCommandsFactory.INSTANCE.createParameter();

parameter.setName(ADDONS_MINMAX_TRIM_STACK_ID);

parameter.setValue(element.getElementId());

toolItem.getParameters().add(parameter);

 

I see the “Restore” tool item in my left TrimBar, but when I click on it I get:

Failed to execute: org.eclipse.e4.ui.model.application.commands.impl.CommandImpl@4f087f (elementId: com.toedter.e4.ui.workbench.addons.minmax.restore, tags: null, contributorURI: kai) (commandName: Restore Stack, description: xxx)

 

If I commend out the MParameter block, nothing happens at all.

 

Any suggestions?

 

Thanks

 

Kai
