class wpilib.SendableChooser[source]

Bases: wpilib.Sendable

A useful tool for presenting a selection of options to be displayed on the SmartDashboard

For instance, you may wish to be able to select between multiple autonomous modes. You can do this by putting every possible Command you want to run as an autonomous into a SendableChooser and then put it into the SmartDashboard to have a list of options appear on the laptop. Once autonomous starts, simply ask the SendableChooser what the selected value is.


# This shows the user two options on the SmartDashboard
chooser = wpilib.SendableChooser()
chooser.addObject('option1', '1')
chooser.addObject('option2', '2')

wpilib.SmartDashboard.putData('Choice', chooser)

# .. later, ask to see what the user selected?
value = chooser.getSelected()

Instantiates a SendableChooser.

DEFAULT = 'default'
OPTIONS = 'options'
SELECTED = 'selected'
addDefault(name, object)[source]

Add the given object to the list of options and marks it as the default. Functionally, this is very close to addObject(...) except that it will use this as the default option if none other is explicitly selected.

  • name – the name of the option
  • object – the option
addObject(name, object)[source]

Adds the given object to the list of options. On the SmartDashboard on the desktop, the object will appear as the given name.

  • name – the name of the option
  • object – the option

Returns the object associated with the selected option. If there is none selected, it will return the default. If there is none selected and no default, then it will return None.

Returns:the object associated with the selected option
