// version of the += operator that retains the type information of the window, in case
// the window implements its own += overloads (one example is pxStaticText).  Without the

// sizer, and would thus fail to invoke the correct operator overload.

//  * Automatic 'primary box sizer' creation, assigned via SetSizer() -- use GetSizer()
//    to retrieve it, or use the "*this += window;" syntax to add windows directly to it.
//
//  * Built-in support for StaticBoxes (aka groupboxes).  Create one at construction with
//    a wxString label, or add one "after the fact" using AddFrame.
//
//  * Propagates IdealWidth settings from parenting wxPanelWithHelpers classes, and auto-
//    matically adjusts the width based on the sizer type (groupsizers get truncated to
//    account for borders).
