Tying/binding Eclipse Commands to a swt button

Question

In Eclipse you can use menu contributions to add toolbar buttons and menus that will call a command. Is there any way to do this to normal swt buttons, apart from programmatically calling the command onclick?

button.addSelectionListener(new SelectionAdapter() {

    @Override
    public void widgetSelected(SelectionEvent e) {
        IHandlerService handlerService = (IHandlerService) getSite()
                .getService(IHandlerService.class);
        try {
            handlerService.executeCommand("my command id", null);
        } catch (Exception ex) {
            throw new RuntimeException("command with id \"my command id\" not found");
        }

    }
});

Other way to get the handle service. IHandlerService handlerService = (IHandlerService) PlatformUI.getWorkbench().getService(IHandlerService.class); – Kondal Kolipaka Jun 08 '17 at 07:33

No. You have to listen for the button event and the invoke the command programmatically.

You can use CommandContributionItems in a View or Wizard like that:

CommandContributionItemParameter param = new CommandContributionItemParameter(getSite(),
            "myCommand", "com.voo.myCommand", CommandContributionItem.STYLE_PUSH);
param.label = "My Label";
CommandContributionItem item = new CommandContributionItem(param);
item.fill(parent);
