Buttons without Scheduler

I need to implement functionality with buttons on the SmartDashboard which do things to the robot. I do not want to use Scheduler, since we are not using command-based. Is there a way to do this without making a smartdashboard widget and hack network tables backwards?

    private ITable table;

    public void initTable(ITable table){

        this.table = table;

        if(table!=null){

            table.putBoolean("pressed" false);

        }

    }

    

    /**

     * {@inheritDoc}

     */

    public ITable getTable(){

        return table;

    }

to check if the button is currently pressed on the dashboard, just use

Code:

table.getBoolean("pressed");

(not 100% sure about this but thats how Trigger does it)

e/ No. send it to the dashboard via

Code:

SmartDashboard.putData(yourButton)

than get it via

Code:

SmartDashboard.getData(yourButton

SmartDashboard.getData() is no longer a method in the wpilibj. It was removed in 2013...

Re: Buttons without Scheduler

We've decided to not bother with it because the feature really isn't needed, but thank you for helping anyway.

Re: Buttons without Scheduler

I haven't tried it, but have you looked at NetworkButton?
