Go Up to View Menu


Adds a property to a class in the C++ Class Explorer.

On the C++ Class Explorer Window, invoke the Add Property dialog box from either:

  • The Add a new property to this class ClExplAddProperty.png toolbar button
  • The context menu command Add property.
Note: The Add Property context menu command and the Add a new property to this class ClExplAddProperty.png toolbar button are enabled only for elements that are declared in a C++ managed unit. To create a C++ unit, choose either:
  • File > New > Unit - C++Builder
  • File > New > Form - C++Builder
C++ managed units differ from ordinary C++ source files in that the header (.h) and implementation (.cpp) files are grouped together. For a C++ managed unit, the Code Editor displays a tab for the .cpp file and a tab for the .h file along the bottom of the window.
You cannot add fields, methods, or properties to VCL or FireMonkey elements using the C++ Class Explorer.
