Replace compiler/preprocessor/platform macro "WIN32" with "_WIN32". Replace "WIN32" in text and documentation with "Windows". Replace "MSWindows" with "Windows". To do: README.Windows.txt (and maybe other documentation as well) needs updates. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12655 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

/**
|
|
This is the FLTK text input widget. It displays a single line
|
|
of text and lets the user edit it. Normally it is drawn with an
|
|
inset box and a white background. The text may contain any
|
|
characters, and will correctly display any UTF text, using
|
|
^X notation for unprintable control characters. It assumes the
|
|
font can draw any characters of the used scripts, which is true
|
|
for standard fonts under Windows and Mac OS X.
|
|
Characters can be input using the keyboard or the character palette/map.
|
|
Character composition is done using dead keys and/or a compose
|
|
key as defined by the operating system.
