questions about GetDDescription [SOLVED]

Sometimes, Cinema will ask you for the description of only a single element. If the singleid you get is not nullptr, you should fill the Description only for this DescID and leave everything else out (important for performance reasons)

thanks Niklas for clarification, so this function won't change the behavior of anything, just a performance check "so I can put it there and forget about it without worries"

what about question 3

Hi Mohamed,
sorry, I wanted to get to your issues way earlier...
To be honest, I'm not sure about question 3. I know, you can have your own popup menu (I think, that's what it is called in SDK docs) on a GeUserArea, when programming your own CustomGUI. But I don't think this is possible in normal descriptions. And I don't recall having seen this anywhere. Could you give me a pointer, if (and if, where) this is already done somewhere in C4D.
There is an option to extend the existing popup menus in the same way, as normal menus (see Windows->Customization->Customize Menus to get an idea of the existing menus). Be aware: In this case your change will appear in every occasion this menu is used. I think, there should be very good reasons to go this road. User may not like, getting there popup menus changed.

Hi Andreas,
I think with your reply I'm getting closer to what I need !Smile[URL-REMOVED]
I'm creating a node based material system for my render engine, this material system will have also a tree view representation, this tree view should be able to do "right click" , then add nodes depending on the right click menu

I think you got now an idea about what I'm after, any simple example of GeUserArea and CustomGUI would be appreciated, plus your guidelines

I'll extend the asynctest SDK example tomorrow morning to have a small popup menu.

Mohamed,

in SDK examples AsyncTest.cpp add the following enumeration for some menu IDs (code for R15+) :

enum
{
  MY_POPUP_ID_FIRST = FIRST_POPUP_ID,
  MY_POPUP_ID_SUBMENU,
  MY_POPUP_ID_SUBMENU_FIRST,
};

Then in Bool SDKGradientArea::InputEvent(const BaseContainer& msg) add the following as last else if:

    else if (chn == BFM_INPUT_MOUSERIGHT)
    {
      BaseContainer bcPopupMenu;
      BaseContainer bcSubmenu;
      Int32 mx = msg.GetInt32(BFM_INPUT_X); // of course you can use mouse position to have popup menu be position sensitive
      Int32 my = msg.GetInt32(BFM_INPUT_Y);
      Global2Local(&mx, &my);
      Local2Screen(&mx, &my);
      // instead of building the menu everytime, you may better have a prepared container ready
      bcPopupMenu.SetString(MY_POPUP_ID_FIRST, "First menu entry");
      bcSubmenu.SetString(1, "A submenu");
      bcSubmenu.SetString(MY_POPUP_ID_SUBMENU_FIRST, "Submenu entry");
      bcPopupMenu.SetContainer(MY_POPUP_ID_SUBMENU, bcSubmenu);
      const Int32 menuId = ShowPopupMenu(nullptr, mx, my, bcPopupMenu);
      switch (menuId)
      {
      case MY_POPUP_ID_FIRST:
        GePrint("Execute first popupmenu entry");
        break;
      case MY_POPUP_ID_SUBMENU_FIRST:
        GePrint("Execute first submenu entry");
        break;
      case 0:
        GePrint("Menu got canceled");
        break;
      default:
        DebugStop("Popup Menu: Forgot a new enum value?");
      }
      // maybe use SendParentMessage() if need be
    }

The docs on this topic aren't that bad either: R16 SDK Docs: c4d_gui.h

it is the example LookAtCamera , LookAtCamera::GetDDescription(), all of the written description are created the same way with a check for performance, need to understand how this works, if there is no specific explanation , is it safe to do the same with all created description? (so I just write them the same way and forget about them) , or this is written in specific situations

You mean the

if (!singleid ||...

part?
Yes, you should do it exactly like it is done in the lookatcamera example. As Niklas said, it's a performance optimization, in case C4D is asking for a single description only.

sorry for asking again, but I found that I didn't know yet how to adjust the format of data "question (2)" , the above link that I posted was for Dialogs, didn't notice this, so hope you may reply with a simple example to question (2)

edit:I find that DESC_COLUMNS is doing the job, but what about putting stuff in an irregular way, like:

button1 button2 button3
button4
button5 button6
button7

edit2: I would love to know how to create something similar to this Dialog http://www.andrewnoske.com/wiki/Cinema_4D_-_my_C%2B%2B_plugins_-_add_text
in GetDDescription() , the combo box, the radio group, etc..

Hi Andreas,

as this is related to ShowPopupMenu()
how to put icons in the menu?
