GUI Commands

CommandData based commands implement simple actions and can be invoked programmatically:

• Some functions can be used to check and invoke Cinema 4D commands, see Command Utility Manual .

Custom Dialog Windows

The Cinema 4D GUI is based on "dialog" windows based on the GeDialog class. A plugin can create custom dialog windows for user interaction or to create new managers.

• GeDialog is the base class for custom dialogs, see GeDialog 手册 .
• The layout and gadgets of GeDialog window can be defined using text-based resource files. See 资源文件手册 .
• Custom data tyes are displayed using custom GUI elements, see Custom GUI Elements .
• GeUserArea is the base class for custom gadgets used with dialogs, see GeUserArea Manual .
• A TriState object can store multiple values and is used to set the value displayed by a GeDialog gadget (for example in situations when editing parameters of multiple objects in parallel), see TriState Manual .
• Multiple messages are sent to and from dialogs and user areas. See GUI and Interaction Messages Manual .

Custom GUI elements are based on GeUserArea and CustomGuiData .

File selection dialogs are handled with the Filename class, see Filename Manual . Functions to open default message and question dialogs are defined in c4d_gui.h .

Parameter Descriptions

Parameters of NodeData based plugins are displayed in the Attribute Manager. They are stored in a so-called parameter description.

• A 描述 object stores the parameter description, see Description Manual .
• The type and properties of NodeData parameters can be defined using text-based resource files. See 资源文件手册 .
• A DynamicDescription object stores the user data description, see DynamicDescription Manual .
• The display and behaviour of a parameter is defined using multiple settings, see Description Settings Manual .

视口

The interactive viewport displays the currently active scene. By implementing a "Draw" function it is possible to draw in this viewport to add custom visualisations:

• A BaseView / BaseDraw object represents a viewport window, see BaseView / BaseDraw Manual .
• A BaseView / BaseDraw object is typically used in a "Draw" functions, see Draw Manual .
