Scripting Instrument Controls in Altium Designer
The Tool Palette's Instrument Controls tab contains components (controls) that are used to design an Altium Designer 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.
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.
Use the following list to navigate to information on the methods available for each component in the Instrument Controls category:
