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

@Paul,

Even if I don’t use a parameter the handler is never invoked.

yes, but I was not sure if this is necessary if both command and handler are “local”, meaning only relevant to a dynamically created tool item.

For testing I have put them in comments, but if I un-comment and register them both with the application has no effect.

 

BTW, the same code block works if I add something to the main tool bar, but in this case I add the tool item to a toolbar within the left trim.

Direct tool items work perfectly but they don’t support parameters, that’s why I wanted to use a command.

 

Best regards,

 

Kai

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");

 You need to use command.getParameters() to add the matching MCommandParameter definition.

 

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

I assume you are adding the command and handler to the application, right?
 

Later,
PW
