A Wheel can be created to control Pandoras Box device parameters or the sequence opacity, additionally you can retrieve and set its value with nodes and Object and Member Notation.


To create a wheel right-click anywhere on the empty main background window and go to "Widgets">"Fader Controls">"Wheel Vertical" or “Wheel Horizontal”.

Once you have clicked on the last menu item the mouse cursor will change to a cross hairs icon. This icon tells you that you are in the create mode.
To create one or multiple wheels just left click anywhere on the empty main background window and you will see a new wheel being assigned and displayed.
The wheel may now be clicked on and moved up and down.

To create a Wheel widget choose "Widgets > Faders > Wheel (Vertical or Horizontal)". The mouse cursor changes to a crosshair icon, indicating the create mode. With a left-click anywhere on the empty main background window you add the selected widget to the current page. Left-click again if you like to add one more. To quit the create mode, you can switch to the run mode with [F8], where you can use all widgets. Most widgets however need to be set up first.

To edit the Wheel’s parameters simply right-click on the desired Wheel control and choose the menu entry "Item Properties", press [ALT+P] whilst the mouse is hovering above it or double-click on it when being in the edit / move mode ([F9]). The Wheel property dialog opens up.



A unique name can be entered to identify the widget via the Object and Member Notation. The default name is based on the widget type and ID.


This drop-down offers all available pages to place the widget on.

The Wheel’s ID may be changed by entering a new one in the text field top left. If you change it, you will be asked if you also want to adapt the name to the new ID.


A short note can be added here. It is not displayed outside the widget but can be set and retrieved with the WidgetID.Note property member.


Uncheck this box to hide the widget.

When the option “Fix” is checked, the Wheel will be displayed on every page.


Enter a pixel size for the Wheel's size.

Wheel Style

Three images can be assigned to the different parts of the Wheel, "Frame", “Handle” and “Background”.


Click on the "..." button to open a file dialog where you can choose your path and image. If you like to choose an image from the Widget Designer "library", click on the "Res" button. The Resource Manager opens where you can double-click on the image of your choice. You can also save custom images in the Resource Manager to access them faster. The small "x" at the right sets the default image.

With the Orientation parameter, you can set your Wheel either vertically or horizontally.

Show Frame

Uncheck this box to hide the frame.


Check this box to directly control the opacity of a Sequence and enter the respective sequence ID.


Check this box to invert your value.

Check the box on the right to send the Wheel value to a Device (layer) parameter. Enter the Site and Device ID of the respective Device, multiple Devices can be entered too, with a white space as separator (e.g.: "2.1 2.2 2.17)


This drop-down offers you all available Device parameters of Pandoras Box. If you want to access an FX parameter, use the FX name and the pipe symbol to specify it (e.g.: "RGB Multiply|Blue"). If the parameter list does not show the desired parameter (in case that you use a custom device) simply type in the name of the parameter here.

Minimum / Maximum
Enter here the minimum and maximum value your Wheel should have, as well as the Default position of the handle.

Mouse Wheel Input

Ui Effects & Animations

CSS based effects and animations can be applied to this widget. Please refer to the topic Effects & Animations for more information.

Network Broadcasting

The NBS (Network Broadcast Service) allows to transmit and update Faders, Labels and Custom Script Buttons across multiple WD Designers instances on the network.

To activate this service, please refer to the IP Configuration!

Enable Send
To send the Wheel values as broadcast into the network, you only have to check “Enable Send”.

Enable Receive
To receive values from other Wheels, please check “Enable Receive”.

Now you have to specify which item should update your Wheel:

Enter the IP address of the computer you want to listen to. This could be the local computer (to control the Wheel through another item on the same Widget Designer) or a different computer in the network. If you do not want to specify the computer but want to listen to all computers in the network, enter “”.

As next step specify the item you want to take the values from. This could e.g. be “Wheel1” or “Wheel2

Once all values are set, the Wheel is ready to be used or edited at any time.
