## API

Bases: `QDialog`

A Widget to define the pixel size configurations using the objective device.

It *requires* to have installed on the microscope a *motorzed objective turret* and allows to set the pixel size using only the *motorzed objective turret device* properties. No other properties can be assigned to the pixel configuration. For this purpose, use the PixelConfigurationWidget which is more similar to the original micromanager pixel configuration widget.

Parameters:

| Name | Type | Description | Default |
| --- | --- | --- | --- |
| `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` |
