kill field( obsolete and removed in FB 5.7.104 ) | statement | |
|
kill field handle&
handle&
gets released, and the value in handle&
is thereafter no longer a valid handle. kill field
is commonly used with handles returned by get field
or read field
, but it can dispose of any kind of handle. However, you should specifically not use it to dispose of resources, regions, window controls, and other "standard" kinds of Macintosh objects which are created and managed by the MacOS. Instead, you should use the appropriate Toolbox routine (ReleaseResource, DisposeRgn, DisposeControl, etc.) to dispose of such objects.kill field
is similar to the Toolbox call DisposeHandle
, except that it (like the DisposeH
statement) checks for _nil
handles and sets the handle&
variable to zero.
