+// A button is a control that contains a text string, and is one of the most
+// common elements of a GUI. It may be placed on a dialog box or panel, or
+// indeed almost any other window.
+//
+// Styles
+// wxBU_LEFT: Left-justifies the label. WIN32 only.
+// wxBU_TOP: Aligns the label to the top of the button. WIN32 only.
+// wxBU_RIGHT: Right-justifies the bitmap label. WIN32 only.
+// wxBU_BOTTOM: Aligns the label to the bottom of the button. WIN32 only.
+// wxBU_EXACTFIT: Creates the button as small as possible instead of making
+// it of the standard size (which is the default behaviour.)
+//
+// Events
+// EVT_BUTTON(win,id,func):
+// Sent when the button is clicked.
