When do button controls etc get deleted?

[Ilitirit]

from examplepopupwnd.cpp:

code:


int ExamplePopupWnd::createChildWindows( void ) {

  // We work from a button, just because that's the easiest

  // way to get some events to toss up some popup menus on the screen.

  ButtonWnd * myButton = new ButtonWnd;

  myButton->setNotifyId(1);

  myButton->setNotifyWindow(this);

  myButton->setButtonText("Click me, bitch!",16);

  addChild(StylePosWnd::ChildInfo(myButton,

    StylePosWnd::ChildEdgeInfo(160, StylePosWnd::CENTER),     // Left

    StylePosWnd::ChildEdgeInfo(25, StylePosWnd::CENTER),      // Top

    StylePosWnd::ChildEdgeInfo(160, StylePosWnd::CENTER),     // Right

    StylePosWnd::ChildEdgeInfo(25, StylePosWnd::CENTER)));    // Bottom

  // "A 160x25 button always in the center."



  return 1;

}

myButton gets "newed" but where does it get deleted?
same with the PopMenus in the handleChildNotify method.

or is this just one of those things that we don't have to worry about?
