CustomGuiData Class Reference

#include <c4d_customguidata.h>

Inheritance diagram for CustomGuiData:

Detailed Description

A data class for creating custom GUIs for data types. These can be used in descriptions for the Attribute Manager.
Use RegisterCustomGuiPlugin() to register the custom GUI plugin.

Note

Even if a library is not created it is needed to call InstallLibrary() for a dummy library during registration:

Bool RegisterExampleDataTypeGui()
{
  static BaseCustomGuiLib mylib;
  ClearMem(&mylib, sizeof(mylib));
  FillBaseCustomGui(mylib);
  if (!InstallLibrary(MYCUSTOMGUI_ID, &mylib, 1000, sizeof(mylib)))
    return false;
 
  return RegisterCustomGuiPlugin("My Custom GUI", 0, NewObj(MyCustomGui));
}

Member Function Documentation

GetId()

virtual Int32 GetId ( )

pure virtual

Called to get the plugin ID of the custom GUI.

Returns

A unique plugin ID. Must be obtained from http://www.plugincafe.com

Alloc()

virtual CDialog* Alloc ( const BaseContainer &  settings )

pure virtual

Called to allocate a sub-dialog for the custom GUI.
Normally this method override should look like this:

virtual CDialog* Alloc(const BaseContainer& settings)
{
  T* dlg = NewObj(T(settings, GetPlugin()));
  if (!dlg)
    return nullptr;
 
  CDialog *cdlg = dlg->Get();
  if (!cdlg)
    return nullptr;
 
  return cdlg;
}

In the above code T stands for a type derived from iCustomGui.

Parameters

[in]

settings

The settings for the GUI. (Using the IDs defined by GetProperties().)

Returns

The allocated sub-dialog.

Free()

virtual void Free ( CDialog *  dlg, void *  userdata  )

pure virtual

Called to free sub-dialogs allocated by Alloc().
Normally this method override should look like this:

virtual void Free(CDialog *dlg, void *userdata)
{
  if (!dlg || !userdata)
    return;
  T* sub = static_cast<T*>(userdata);
  DeleteObj(sub);
}

In the above code T stands for a type derived from iCustomGui.

Parameters

[in,out]	dlg	The sub-dialog to free.
[in]	userdata	The user data.

GetResourceSym()

virtual const Char* GetResourceSym ( )

pure virtual

Called to get the symbol to use in resource files, for example "GRADIENT".

Note

Only 7-bit ASCII characters are allowed, hence the Char type.

Returns

A pointer to a global const Char* string with the resource symbol.

GetProperties()

virtual CustomProperty* GetProperties ( )

virtual

Called to get the properties that the custom GUI accepts in resource files.

See also

CustomProperty.

Returns

A pointer to a global array of CustomProperty elements, ended with a CUSTOMTYPE::END property:

CustomProperty bitmapbuttonprops[] =
{
  { CUSTOMTYPE::FLAG, BITMAPBUTTON_BORDER, "BORDER" },
  { CUSTOMTYPE::FLAG, BITMAPBUTTON_BUTTON, "BUTTON" },
  { CUSTOMTYPE::END, 0, nullptr }
};

GetResourceDataType()

virtual Int32 GetResourceDataType ( Int32 *&  table )

virtual

Called to return the IDs of compatible data types for the custom GUI.

See also

CustomDataTypeClass::GetConversionsFrom.

Parameters

[out]

table

Set this to point to a global array with the IDs of compatible data types for the custom GUI.

Returns

The length of the array pointed by table, or 0 if table has not been set.

GetPlugin()

CUSTOMGUIPLUGIN* GetPlugin

(

)

Gets the plugin structure for the custom GUI.

Returns

The custom GUI plugin structure. Cinema 4D owns the pointed plugin structure.
