// This event type is used to transfer message boxes to the main UI thread, and return the
// result of the box. It's the only way a message box can be issued from non-main threads
// with complete safety in wx2.8.
//
// For simplicity sake this message box only supports two basic designs. The main design
// is a generic message box with confirmation buttons of your choosing. Additionally you
// can specify a "scrollableContent" text string, which is added into a read-only richtext
// control similar to the console logs and such.
//
// Future consideration: If wxWidgets 3.0 has improved thread safety, then it should probably
// be reasonable for it to work with a more flexable model where the dialog can be created
// on a child thread, passed to the main thread, where ShowModal() is run (keeping the nested
// message pumps on the main thread where they belong). But so far this is not possible,
// because of various subtle issues in wx2.8 design.
