Get the Windows handle of a window or of the R process.
Usage
getWindowsHandle(which = "Console")
Arguments
which
A string (see below), or the number of a
graphics device window
Value
An external pointer holding the Windows handle, or NULL.
Details
getWindowsHandle gets the Windows handle.
Possible choices for which are:
"Console"
The console window handle.
"Frame"
The MDI frame window handle.
"Process"
The process pseudo-handle.
These values are not normally useful to users, but may be used by
developers making add-ons to R. NULL is returned for the Frame handle if not running in MDI mode,
for the Console handle when running Rterm, for any unrecognized
string for which, or for a graphics device with no
corresponding window. Other windows (help browsers, etc.) are not accessible
through this function.
