Programmatically control the mouse and keyboard.

Currently, mouse and keyboard control works well on Windows 10. This library doesn't work with earlier Windows versions because it relies on the latest functionality around DPI awareness.

This code thinks of your displays the same way Windows 10 does: see The Virtual Screen for details.

The minimal bounding box around all displays is called the virtual screen. The top left corner of the primary monitor has the coordinates (0, 0). So (0, 0) isn't necessarily the top left corner of the virtual screen when you have multiple displays. The coordinates can even be negative.

The coordinate system always uses the displays' current resolution and ignores Windows 10 display scaling. For example, my laptop has a 3200x1800 display and its resolution is the same 3200x1800 but with 250% scaling. When an application is DPI unaware, Windows will report the size as 1280x720. But this project ignores that and uses 3200x1800 coordinates. On the other hand, if I changed the actual display resolution to 1280x720 instead of the scaling factor, then it will use coordinates within the 1280x720 range.

Mouse buttons in the functionality described later are one of the following keywords:

• :LEFT
• :MIDDLE
• :RIGHT
• :XBUTTON1
• :XBUTTON2
• :PRIMARY
• :SECONDARY

:LEFT and :RIGHT are always the left and right mouse buttons regardless of whether or not the user has the mouse buttons swapped. :PRIMARY and :SECONDARY are the same as :LEFT and :RIGHT, unless the user has the mouse buttons swapped. Then they'll be mapped the other way around. Mouse button clicking functions default to the :PRIMARY button unless another button is explicitly passed in.

:XBUTTON1 and :XBUTTON2 are the two extra mouse buttons which may be on the side of the mouse. For example in web browsers these can be the back and forward buttons, respectively.

These are in the progui package:

rect: A rectangle class containing left and top X,Y coordinates plus width and height. rect-left, rect-top, rect-width, and rect-height are accessors.

virtual-screen-rect: Return a rect showing the bounding rectangle around all the monitors.

(progui:virtual-screen-rect)
=> #<PROGUI:RECT left: -1920 top: 0 width: 4480 height: 1440 4020012263>

get-cursor-position: Return the X, Y virtual screen coordinates of the cursor in a cons.

(progui:get-cursor-position)
=> (138 . 463)

move-cursor: Move the cursor to the given (X, Y) coordinate. Return T if the event was successfully sent.

(progui:move-cursor -1200 234)
=> T

move-cursor-smoothly: Move the cursor from its current position to (X, Y) over a duration given in seconds. Return T if the cursor ends at the given position. Basically, this makes it so you can see the cursor gradually move to its destination instead of instantly moving there.

(progui:move-cursor-smoothly 0 0 3/4)
=> T ; moves the cursor to (0, 0) over 3/4 of a second duration

(progui:move-cursor-smoothly 1000 1000)
=> T ; moves the cursor to (1000, 1000) over half a second duration

(progui:get-cursor-position)
=> (0 . 0) ; position at the start
(progui:move-cursor-smoothly 10000 10000)
=> NIL ; out of range, can't move there
(progui:get-cursor-position)
=> (2559 . 1439) ; it tried to gradually move there but stopped at the corner

press-mouse-button: Press the given mouse button. Return T if the event was successfully sent.

(progui:press-mouse-button :primary)
=> T

release-mouse-button: Release the given mouse button. Return T if the event was successfully sent.

(progui:release-mouse-button :primary)
=> T

get-double-click-time: Return the maximum number of seconds delay between two clicks to count as a double-click.

(progui:get-double-click-time)
=> 1/2

click-mouse-button: Click (press and release) the given mouse button. The optional num-times parameter says how many times to click. Return T if all the events were successfully sent.

(progui:click-mouse-button)
=> T ; clicks the :PRIMARY mouse button which is the same as :LEFT unless the
     ; user has the :LEFT and :RIGHT mouse buttons swapped

(progui:click-mouse-button :left)
=> T ; clicks the :LEFT mouse button regardless of the user's mouse button
     ; swap settings

(progui:click-mouse-button :left 2)
=> T ; clicks the left mouse button twice in a row (double-click)

double-click-mouse-button: Double click the given mouse button. The optional seconds-between-clicks parameter is the length of time in seconds to sleep between clicks. Return T if all the events were successfully sent.

(progui:double-click-mouse-button)
=> T ; double click the :PRIMARY mouse button

(progui:double-click-mouse-button :middle 0.1)
=> T ; click the middle mouse button, wait 0.1 seconds, click it again

rotate-mouse-wheel: Rotate the mouse wheel vertically, forward or backward. The parameter is the number of clicks. Positive values rotate the wheel forward, away from the user, and negative values rotate the wheel backward, towards the user. Return T if the event was successfully sent.

(progui:rotate-mouse-wheel 12)
=> T

rotate-mouse-wheel-horizontally: Rotate the mouse wheel horizontally. The parameter is the number of clicks. Positive values rotate the wheel to the right, and negative values rotate the wheel to the left. Return T if the event was successfully sent.

(progui:rotate-mouse-wheel-horizontally -4)
=> T

*keys*: A list of keyword symbols representing keys that be passed into other keyboard functions.

progui:*keys*
=> (:VK-F2 :VK-2 :VK-OEM-WSCTRL ...

press-key: Press the given key. Return T if the event was successfully sent.

(progui:press-key :vk-a)
=> T

release-key: Release the given key. Return T if the event was successfully sent.

(progui:release-key :vk-a)
=> T

key-pressed-p: Return T if the key is currently pressed down.

(progui:key-pressed-p :vk-a)
=> NIL
