Instrument Controls
Parent page: Component Categories
The Tool Palette's Instrument Controls tab contains components (controls) that are used to design an Altium NEXUS Custom Instrument panel GUI. These controls are specifically for use with the Custom Instrument.
► See Custom Instrument GUI - Available Instrument Controls for a functional description of each Instrument Control.
To view the associated Properties and Events for an Instrument Control component placed on a script Form, use the Properties or Events tab in the Object Inspector panel (View » Panels » Object Inspector).
To find a particular Method (or Property) for an Instrument Control, use the Code Completion feature (see Script Editor Tools). For example, by typing TInstrumentCheckBox.get the Code Completion window will show a suitably filtered list of methods and properties for TInstrumentCheckBox component. Use Ctrl+Space to manually instigate the Code Completion window.
Use the Code Completion (Ctrl+Space) feature to see the available Methods or Properties for a component.
Inheritance
The majority of Instrument Control classes inherit their Methods (and Properties and Events) from the Delphi VCL TGraphicControl or TCustomControl base classes. Therefore the Instrument Control methods covered here are in addition to one of those base classes, as noted in each entry reference.
By way of example, the descending inheritance for the TInstrumentCheckBox control is as follows:
| Inheritance path | Methods |
|---|---|
TGraphicControl |
See the matching Delphi reference. |
TCustomInstrumentCheckBox |
See the TXPCheckBox entry below. |
TInstrumentCheckBox |
See the TXPCheckBox entry below. |
Component Methods
The Altium Instrument Control components are based on core classes from the Embarcadero Visual Component Library (VCL). Each Instrument Control inherits the methods, properties and events from its VCL source, and most offer additional custom methods. For example, both the TInstrumentCheckBox component and the standard TCheckBox component offer the Click method, whereas the TInstrumentCheckBox component also provides the Changed method.
