Supported Third-Party VCL Controls

Recognizing Custom Controls

TestLeft can work with any VCL and CLX controls via graphical user interface. It checks a control’s class name and automatically associates it with the appropriate interface.

Most VCL and CLX controls are supported as standard Windows controls (see Supported Standard Windows Controls). Besides that, TestLeft provides extended support for some specific Delphi and C++Builder controls (see below). These controls are automatically associated with interfaces that extend the controls’ functionality with a number of supplementary methods and properties. Use these extended methods and properties to perform various operations over the controls, for example, select individual items or retrieve the item text.

The table below contains VCL and CLX controls for which TestLeft provides extended support.

Besides standard VCL controls included in Delphi and C++Builder, TestLeft supports controls of other vendors, such as Developer Express or TMS Software. For a list of supported third-party VCL controls, see the following topics:

To command TestLeft to recognize your custom controls as VCL and CLX controls, cast your control to the interface of the appropriate type.

If your control does not fit the type of the control, for which the interface provides support, it may improperly respond to commands that TestLeft will send, and simulating user actions against your control may cause errors.
