Remarks

This class implements the basic functionality required by most of the DevExpress VCL controls. Various descendant controls publish certain TcxControl class members, depending on the functionality that a particular control has.

The TcxControl class extends its ancestor with members that allow you to:

Identify if the control can accept focus (CanFocusEx).
Customize look & feel settings or switch between available render modes (LookAndFeel).
Specify the control’s border style appearance (BorderStyle).
Identify the control’s current state (IsDesigning, IsDestroying, IsFocused, and IsLoading).
Assign a hint message to the control (Hint).
Specify whether the control’s background is transparent in GDI render mode (Transparent).
Access the control’s GDI-based canvas (ActiveCanvas and Canvas).
Associate a specific popup menu with the control (PopupMenu).
Specify whether the control becomes focused when clicked (FocusOnClick).

Do not use the TcxControl class directly. Use its descendants instead.
