handle

Arguments: window

Returns the integer that the operating system uses to identify a window. An application should need this function only if it is programming partly in Common Graphics and partly at the Windows API level, in which case this function returns the handle of a Common Graphics window to pass directly to Windows API functions that require the window handle. The related function device-context returns the device-context integer.

The home package of the symbol naming this function is windows but it is also exported from the common-graphics package. (This is necessary because handle is exported from another package used by the common-graphics package.) Note that this function is not available in images into which the Common Graphics module has not been loaded.
