+\subsection{Themed borders on Windows}\label{wxmswthemedborders}
+
+Starting with wxWidgets 2.8.5, you can specify the wxBORDER\_THEME style to have wxWidgets
+use a themed border. Using the default XP theme, this is a thin 1-pixel blue border,
+with an extra 1-pixel border in the window client background colour (usually white) to
+separate the client area's scrollbars from the border.
+
+If you don't specify a border style for a wxTextCtrl in rich edit mode, wxWidgets now gives
+the control themed borders automatically, where previously they would take the Windows 95-style
+sunken border. Other native controls such as wxTextCtrl in non-rich edit mode, and wxComboBox,
+already paint themed borders where appropriate. To use themed borders on other windows, such
+as wxPanel, pass the wxBORDER\_THEME style, or (apart from wxPanel) pass no border style.
+
+In general, specifying wxBORDER\_THEME will cause a border of some kind to be used, chosen by the platform
+and control class. To leave the border decision entirely to wxWidgets, pass wxBORDER\_DEFAULT.
+This is not to be confused with specifying wxBORDER\_NONE, which says that there should
+definitely be {\it no} border.
+
+\wxheading{More detail on border implementation}
+
+The way that wxMSW decides whether to apply a themed border is as follows.
+The theming code calls wxWindow::GetBorder() to obtain a border. If no border style has been
+passed to the window constructor, GetBorder() calls GetDefaultBorder() for this window.
+If wxBORDER\_THEME was passed to the window constructor, GetBorder() calls GetDefaultBorderForControl().
+
+The implementation of wxWindow::GetDefaultBorder() on wxMSW calls wxWindow::CanApplyThemeBorder()
+which is a virtual function that tells wxWidgets whether a control can have a theme
+applied explicitly (some native controls already paint a theme in which case we should not
+apply it ourselves). Note that wxPanel is an exception to this rule because in many cases
+we wish to create a window with no border (for example, notebook pages). So wxPanel
+overrides GetDefaultBorder() in order to call the generic wxWindowBase::GetDefaultBorder(),
+returning wxBORDER\_NONE.
