Types of Toolbar Items
There are a variety of toolbar items that you can create in OpenROAD Workbench, each serving a different functional purpose. All of these toolbar items should be familiar to you already because they are basic OpenROAD fields:
Button Field
Lets the user initiate an operation by clicking it. You can specify text or an image as the label for the button.
Option Field
Appears as a drop-down list of values from which the user can make one selection. Only the current value is displayed. In addition to selecting the current value, the user can click the down arrow to select another value from the drop‑down list.
Space
Separates toolbar items for display purposes only
Toggle Field
Appears as an option that the user can click on or off (enable or disable). The label for a toggle can be either text or an image. You can supply one text phrase for both states and use the toggle indicator, or you can turn off the toggle indicator and supply separate phrases or images for the on and off states.
