API¶

Bases: QWidget

Combo box that shows and sets the current objective.

Parameters:

Name	Type	Description	Default
`objective_device`	`str \| None`	Device label for the micromanager objective device. By default, it will be guessed using the `CMMCorePlus.guessObjectiveDevices` method and a choice dialog will be presented if there are multiple options. This method looks for a micromanager device matching the default regex `re.compile("(.+)?(nosepiece\|obj(ective)?)(turret)?s?", re.IGNORECASE)`. To change the search pattern, set `CMMCorePlus.objective_device_pattern`.	`None`
`parent`	`QWidget \| None`	Optional parent widget, by default None	`None`
`mmcore`	`CMMCorePlus \| None`	Optional `pymmcore_plus.CMMCorePlus` micromanager core. By default, None. If not specified, the widget will use the active (or create a new) `CMMCorePlus.instance`.	`None`
