Scripting Component Categories in Altium NEXUS

The Scripting system's visual form controls, based on Embarcadero's Visual Component Library (VCL), are represented by a wide range of conventional Delphi-type component objects and two specialized Altium component categories — the Altium Standard and Instrument Controls groups.

► Refer to the component categories in the Embarcadero VCL documentation for full details on the methods, properties and events for the majority of components.

The two specialized categories (expandable sections) in the Altium NEXUS Tool Palette – Altium Standard and Instrument Controls – are derived from standard Delphi-type components, but are not specifically included in the Embarcadero reference documentation.

Component Events and Properties

To see a list of Events and Properties for a component:

• Select a component on the Form and activate the Events or Properties tab in the Object Inspector panel.
• Select the Events or Properties link on the appropriate component reference page in the Embarcadero documentation. In the case of the TButton control for example, select the Standard category, the TButton page and then the Events or Properties view.

Component Methods

To find a particular Method (or Property) for a Tool Palette component, use the Code Completion feature (see Script Editor Tools). For example, by typing TButton.hi the Code Completion window will show both the Hide procedure and Hint property for the TButton component object. Use Ctrl+Space to manually invoke the Code Completion window.

Use the Code Completion (Ctrl+Space) feature to search for a valid component Method or Property.

Refer to the following sections to find the Methods and further information on the various category in the scripting Tools Palette.
