[ What's my line? ]

OK, here's a little program called ClickUpFront, which is my addition to the
ClickToFront-type utilities.  ClickUpFront installs an input handler that
brings windows (and screens) to the front or back when you double click in them.

To install the handler, just type:

    1> ClickUpFront

It should tell you that it has installed the handler.  You don't have to
RUN ClickUpFront, because it sets up the handler and then exits, leaving only
the input handler in memory.  The handler itself only takes up about 1K of
memory when it is installed, so you shouldn't have to worry about using lots
of memory.

To remove the input handler, simply call ClickUpFront a second time.
ClickUpFront creates a public, named message-port that it uses to hold the
information it needs in order to remove the handler that it installed.  See
the code for details of how this works.

Once ClickUpFront is installed and you double click in a window with the left
mouse-button, that window will be brought to the front of all the other
windows (unless it is a backdrop window).  If the window is on a screen that
is not the front-most screen, then that screen is brought to the front of all
the other screens as well.  You can set the double-click time with the
Preferences tool.  Be careful that you don't move the mouse between clicks
as this will cause ClickUpFront to ignore the double-click.

If you want to be able to send a double-click to a window WITHOUT having it
come to the front, simply hold down one of the shift keys while you click
in the window.  ClickUpFront will ignore double-clicks when a shift key is
pressed.  If you want to use some other qualifier key instead of the shift
keys, you can specify a qualifier-key mask on the commaand line:

    1> ClickUpFront 0x0008

would specify the CTRL key instead of the shift keys.  See the include file
exec/inputevent.h for the hex values for the other qualifier keys.

If you double-click with the right mouse-button, that will push the ACTIVE
window to the back of all the other (non-backdrop) windows.  If the window is
already the back-most window (or there is no active window), then the active
SCREEN will be pushed to the back of all the screens, and the top window on
the next screen will be activated.  As with left mouse clicks, holding down
the shift key will keep the window or screen from being pushed to the back.

Note that Intuition already specifies that a double right mouse-button click
should bring up a double-menu requester.  In the author's experience, few
programs take advantage of this feature.  For those that do, however,
ClickUpFront will ignore double right-button clicks in windows that have DM
requesters UNLESS the shift key is pressed.  That is, in order to push a
window with a DM requester to the back, hold down the shift key and double-
click the right mouse button.


To install ClickUpFront on your disk, simply unshar and uudecode the
executables.  Put ClickUpFront in the C: directory and put Click-Handler in the
L: directory (or the current directory).

To compile and link ClickUpFront, type:

    1> LC -v ClickUpFront Click-Handler
    1> ASM HandlerStub
    1> BLINK WITH ClickUpFront.lnk
    1> BLINK WITH Click-Handler.lnk

You can use the -b and -r options with ClickUpFront, but don't use them for
Click-Handler.

Hope you enjoy this little program!
