|
|
// 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.
