Get the parent

by Katrina Rose · in Torque Game Engine · 12/28/2004 (10:10 am) · 9 replies

I added a onAdd callback to the guiControl file so that I can capture the guiBitmapCtrl files as they are being added to the mission. I am storing them in an array as drop points for a multimeter simulator. My problem is that I need to know what guiControl they are comming from. Example:

IETMGui.gui or IETMEgiGui.gui

That way I can sort them out and put them in there proper array. I have tried %this.getGroup(), but it returns guiGroup. There is no getParent() method or anything that I can find. I thought about adding the parent into the:

Con::executef(this, 2, "onAdd");

but I don't know how to get it from c++ and I don't know where to put it in the line, or where to put it in:

function GuiBitmapCtrl::onAdd( %this, %obj)

Any help is apreciated,

Why dont you add one to the classes you need.
static const char* getClassName() {return("this class name");}

Thanks Westly,


Is getClassName the same as parent? Where would I add that?

Add that to the header file of the class you want it in. You will probably also have to add a console function to call it from script, but SimObject has it so you might not.

@Westy

This returns guiBitmapCtrl. This is my current heirchy:

1. NAME: IETMGui (gui)
2. NAME: IETMGuiWindow (guiWindowCtrl)
3. NAME: Drop1 *(guiBitmapCtrl)

I am at #3 and I need to know the name of Number 1 (IETMGui). I need the name of the gui that the current bitmap is on.

Thanks for your help,

Given GUIs are SimGroup derived, you should be able to use getGroup() or similar to figure out what group a given thing belongs to. Simply call it as many generations as you need, and you'll get the nth parent. Do a dump() on SimGroup (or on the gui control in question) to find the correct method name.

Thanks Ben,

I tried that first, but the problem is that I have to exec in the guiBitmapCtrl::onAdd method before the gui itself or it won't see any of the bitmaps. When I use the getGroup() method and then the getName() all I get is guiGroup. After that I get a -1 for the getName(). I think that's because of the order that I am loading the cs files, but I don't think I can change it without one or the other not working. Thanks for your help,

I don't think it has anything to do with the order of the .cs files. Have you tried using tree() to see how things are set up?

This is how I have things set up:
function GuiBitmapCtrl::onAdd( %this, %obj)
{
  if (%this.bitmapType $= "Drop")
     {
       $myThis = %this;
       %guiWindow = %this.getGroup();
       %gui = %guiWindow.getGroup();
       echo(strUpr(%gui.getName()));
       switch$ (strUpr(%gui.getName()))
       {
       }
      }
}

The echo returns nothing. I used the tree() view and the heirchy is as I described above:

guiCtrl (IETMgui)
guiWindowCtrl (IETMGuiWindow)
guiBitmapCtrl (Drop1)

If I echo(%this.getGroup().getName()) I get guiGroup. If I wait till the game is done loading everything and use:

echo($myThis.getGroup().getGroup().getName());

It returns IETMgui.

I don't understand why it won't work in the onAdd but works after.

Again thanks for your help. Any ideas?

Do you get any console errors?

Also, you're aware that the code you have above, once parsed, will be executed for _all_ GuiBitmapCtrls?
