// 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
// template, the type of the window would only be known as "wxWindow" when it's added to the
// sizer, and would thus fail to invoke the correct operator overload.

// += operator works on either sizers, wxDialogs or wxPanels. In the latter case, the window
// is added to the dialog/panel's toplevel sizer (wxPanel.GetSizer() is used). If the panel
// has no sizer set via SetSizer(), an assertion is generated.

// * Simpler constructors that have wxID, position, and size parameters removed (We never

//
// * 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).
