IupGetNextChild
Returns the children of the given control.
Parameters/Return
Ihandle *IupGetNextChild(Ihandle* ih, Ihandle* child); [in C] iup.GetNextChild(ih, child: ihandle) -> ret: ihandle [in Lua]
ih: identifier of the interface element.
child: Identifier of the last interface control returned by the function.

This function will return the children of the control in the exact same order in which they were assigned. To get the first child use child=NULL.

#include <stdio.h>
#include "iup.h"
int main()
{
Ihandle *dialog, *bt, *lb, *vbox, *tmp = NULL;
IupOpen();
bt = IupButton("Button", "");
lb = IupLabel("Label");
vbox = IupVbox(bt, lb, NULL);
dialog = IupDialog(vbox);

while(1)
{
tmp = IupGetNextChild(vbox, tmp);
