## IupGetNextChild

Returns the a child of the given control given its brother.

### Parameters/Return

    Ihandle *IupGetNextChild(Ihandle* ih, Ihandle* child); [in C]
    iup.GetNextChild(ih, child: ihandle) -> next_child: ihandle [in Lua]

ih: identifier of the interface element. Can be NULL if child not NULL.
child: Identifier of the child brother to be used as reference. To get the first child use NULL.

Returns: the handle of the child or NULL.

### Example

    /* Lists all children of a IupVbox */

    #include <stdio.h>
    #include "iup.h"

    int main(int argc, char* argv[])
    {
      Ihandle *dialog, *bt, *lb, *vbox, *child;

      IupOpen(&argc, &argv);

      bt = IupButton("Button", NULL);
      lb = IupLabel("Label");

      vbox = IupVbox(bt, lb, NULL);

      dialog = IupDialog(vbox);
      IupShow(dialog);

      child = IupGetNextChild(vbox, NULL);

      while(child)
      {
        printf("vbox has a child of type %s\n", IupGetClassName(child));
        child = IupGetNextChild(NULL, child);
      }

      IupMainLoop();
      IupClose();
