DESCRIPTION

       This Perl package is intended to facilitate the testing of GUI applications by means of
       user emulation.  It can be used to test/interact with GUI applications; which have been
       built upon the X library or toolkits (i.e., GTK+, Xt, Qt, Motif, etc.) that "wrap" the X
       library's functionality.

       A basic recorder (x11guirecord) is also available, and can be found in the source code
       respository.

DEPENDENCIES

       An X server with the XTest extensions enabled.  This seems to be the norm.  If it is not
       enabled, it usually can be by modifying the X server configuration (i.e., XF86Config).

       The standard DISPLAY environment variable is utilized to determine the host, display, and
       screen to work with.  By default it is usually set to ":0.0" for the localhost.  However,
       by altering this variable one can interact with applications under a remote host's X
       server.  To change this from a terminal window, one can utilize the following basic
       syntax: export DISPLAY=<hostname-or-ipaddress>:<display>.<screen>  Please note that under
       most circumstances, xhost will need to be executed properly on the remote host as well.

       There is a known incompatibility between the XTest and Xinerama extensions, which causes
       the XTestFakeMotionEvent() function to misbehave.  When the Xinerama (X server) extension
       is turned on, this (Perl) extension has been modified to allow one to invoke an
       alternative function.  See Makefile.PL for details.

INSTALLATION

         perl Makefile.PL
         make
         make test
         make install

         # If you'd like to install the recorder, use these steps:
         cd recorder
         ./autogen.sh
         ./configure
         make
         make install
         x11guirecord --help

SYNOPSIS

       For additional examples, please look under the 'eg/' sub-directory from the installation
       folder.

         use X11::GUITest qw/
           StartApp
           WaitWindowViewable
           SendKeys
         /;

         # Start gedit application
         StartApp('gedit');

         # Wait for application window to come up and become viewable.
         my ($GEditWinId) = WaitWindowViewable('gedit');
         if (!$GEditWinId) {
           die("Couldn't find gedit window in time!");
         }

         # Send text to it
         SendKeys("Hello, how are you?\n");

         # Close Application (Alt-f, q).
         SendKeys('%(f)q');

         # Handle gedit's Question window if it comes up when closing.  Wait
         # at most 5 seconds for it.
         if (WaitWindowViewable('Question', undef, 5)) {
           # DoN't Save (Alt-n)
           SendKeys('%(n)');
         }

FUNCTIONS

Parameters enclosed within [] are optional.

If there are multiple optional parameters available for a function and you would like to
specify the last one, for example, you can utilize undef for those parameters you don't
specify.

REGEX in the documentation below denotes an item that is treated as a regular expression.
For example, the regex "^OK$" would look for an exact match for the word OK.

FindWindowLike TITLEREGEX [, WINDOWIDSTARTUNDER]
Finds the window Ids of the windows matching the specified title regex.
Optionally one can specify the window to start under; which would allow one to
constrain the search to child windows of that window.

An array of window Ids is returned for the matches found. An empty array is
returned if no matches were found.

my @WindowIds = FindWindowLike('gedit');
# Only worry about first window found
my ($WindowId) = FindWindowLike('gedit');

WaitWindowLike TITLEREGEX [, WINDOWIDSTARTUNDER] [, MAXWAITINSECONDS]
Waits for a window to come up that matches the specified title regex. Optionally
one can specify the window to start under; which would allow one to constrain the
search to child windows of that window.

One can optionally specify an alternative wait amount in seconds. A window will
keep being looked for that matches the specified title regex until this amount of
time has been reached. The default amount is defined in the DEF_WAIT constant
available through the :CONST export tag.

If a window is going to be manipulated by input, WaitWindowViewable is the more
robust solution to utilize.

An array of window Ids is returned for the matches found. An empty array is
returned if no matches were found.

my @WindowIds = WaitWindowLike('gedit');
# Only worry about first window found
my ($WindowId) = WaitWindowLike('gedit');

WaitWindowLike('gedit') or die("gedit window not found!");

WaitWindowViewable TITLEREGEX [, WINDOWIDSTARTUNDER] [, MAXWAITINSECONDS]
Similar to WaitWindow, but only recognizes windows that are viewable. When GUI
applications are started, their window isn't necessarily viewable yet, let alone
available for input, so this function is very useful.

Likewise, this function will only return an array of the matching window Ids for
those windows that are viewable. An empty array is returned if no matches were
found.

WaitWindowClose WINDOWID [, MAXWAITINSECONDS]
Waits for the specified window to close.

One can optionally specify an alternative wait amount in seconds. The window will
keep being checked to see if it has closed until this amount of time has been
reached. The default amount is defined in the DEF_WAIT constant available through
the :CONST export tag.

zero is returned if window is not gone, non-zero if it is gone.

WaitSeconds SECONDS
Pauses execution for the specified amount of seconds.

WaitSeconds(0.5); # Wait 1/2 second
WaitSeconds(3); # Wait 3 seconds

ClickWindow WINDOWID [, X Offset] [, Y Offset] [, Button]
Clicks on the specified window with the mouse.

Optionally one can specify the X offset and Y offset. By default, the top left
corner of the window is clicked on, with these two parameters one can specify a
different position to be clicked on.

One can also specify an alternative button. The default button is M_LEFT, but
M_MIDDLE and M_RIGHT may be specified too. Also, you could use the logical Id for
the button: M_BTN1, M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all available
through the :CONST export tag.

zero is returned on failure, non-zero for success

GetWindowFromPoint X, Y [, SCREEN]
Returns the window that is at the specified point. If no screen is given, it is
taken from the value given when opening the X display.

zero is returned if there are no matches (i.e., off screen).

IsChild PARENTWINDOWID, WINDOWID
Determines if the specified window is a child of the specified parent.

zero is returned for false, non-zero for true.

QuoteStringForSendKeys STRING
Quotes {} characters in the specified string that would be interpreted as having
special meaning if sent to SendKeys directly. This function would be useful if
you had a text file in which you wanted to use each line of the file as input to
the SendKeys function, but didn't want any special interpretation of the
characters in the file.

Returns the quoted string, undef is returned on error.

# Quote ~, %, etc. as {~}, {%}, etc for literal use in SendKeys.
SendKeys( QuoteStringForSendKeys('Hello: ~%^(){}+#') );
SendKeys( QSfSK('#+#') );

StartApp COMMANDLINE
Uses the shell to execute a program. This function returns as soon as the program
is called. Useful for starting GUI applications and then going on to work with
them.

zero is returned on failure, non-zero for success

StartApp('gedit');

RunApp COMMANDLINE
Uses the shell to execute a program until its completion.

Return value will be application specific, however -1 is returned to indicate a
failure in starting the program.

RunApp('/work/myapp');

ClickMouseButton BUTTON
Clicks the specified mouse button. Available mouse buttons are: M_LEFT, M_MIDDLE,
M_RIGHT, M_DOWN, M_UP. Also, you could use the logical Id for the button: M_BTN1,
M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all available through the :CONST export
tag.

zero is returned on failure, non-zero for success.

DefaultScreen
Returns the screen number specified in the X display value used to open the
display.

Leverages the Xlib macro of the same name.

ScreenCount
Returns the number of screens in the X display specified when opening it.

Leverages the Xlib macro of the same name.

SetEventSendDelay DELAYINMILLISECONDS
Sets the milliseconds of delay between events being sent to the X display. It is
usually not a good idea to set this to 0.

Please note that this delay will also affect SendKeys.

Returns the old delay amount in milliseconds.

GetEventSendDelay
Returns the current event sending delay amount in milliseconds.

SetKeySendDelay DELAYINMILLISECONDS
Sets the milliseconds of delay between keystrokes.

Returns the old delay amount in milliseconds.

GetKeySendDelay
Returns the current keystroke sending delay amount in milliseconds.

GetWindowName WINDOWID
Returns the window name for the specified window Id. undef is returned if name
could not be obtained.

# Return the name of the window that has the input focus.
my $WinName = GetWindowName(GetInputFocus());

SetWindowName WINDOWID, NAME
Sets the window name for the specified window Id.

zero is returned on failure, non-zero for success.

GetRootWindow [SCREEN]
Returns the Id of the root window of the screen. This is the top/root level
window that all other windows are under. If no screen is given, it is taken from
the value given when opening the X display.

GetChildWindows WINDOWID
Returns an array of the child windows for the specified window Id. If it detects
that the window hierarchy is in transition, it will wait half a second and try
again.

MoveMouseAbs X, Y [, SCREEN]
Moves the mouse cursor to the specified absolute position in the optionally given
screen. If no screen is given, it is taken from the value given when opening the
X display.

Zero is returned on failure, non-zero for success.

GetMousePos
Returns an array containing the position and the screen (number) of the mouse
cursor.

my ($x, $y, $scr_num) = GetMousePos();

PressMouseButton BUTTON
Presses the specified mouse button. Available mouse buttons are: M_LEFT,
M_MIDDLE, M_RIGHT, M_DOWN, M_UP. Also, you could use the logical Id for the
button: M_BTN1, M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all available through
the :CONST export tag.

zero is returned on failure, non-zero for success.

ReleaseMouseButton BUTTON
Releases the specified mouse button. Available mouse buttons are: M_LEFT,
M_MIDDLE, M_RIGHT, M_DOWN, M_UP. Also, you could use the logical Id for the
button: M_BTN1, M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all available through
the :CONST export tag.

zero is returned on failure, non-zero for success.

SendKeys KEYS
Sends keystrokes to the window that has the input focus.

The keystrokes to send are those specified in KEYS parameter. Some characters
have special meaning, they are:

Modifier Keys:
^ CTRL
% ALT
+ SHIFT
# META
& ALTGR

Other Keys:
~ ENTER
\n ENTER
\t TAB
( and ) MODIFIER GROUPING
{ and } QUOTE / ESCAPE CHARACTERS

Simply, one can send a text string like so:

SendKeys('Hello, how are you today?');

Parenthesis allow a modifier to work on one or more characters. For example:

SendKeys('%(f)q'); # Alt-f, then press q
SendKeys('%(fa)^(m)'); # Alt-f, Alt-a, Ctrl-m
SendKeys('+(abc)'); # Uppercase ABC using shift modifier
SendKeys('^(+(l))'); # Ctrl-Shift-l
SendKeys('+'); # Press shift

Braces are used to quote special characters, for utilizing aliased key names, or
for special functionality. Multiple characters can be specified in a brace by
space delimiting the entries. Characters can be repeated using a number that is
space delimited after the preceding key.

Quote Special Characters

SendKeys('{{}'); # {
SendKeys('{+}'); # +
SendKeys('{#}'); # #

You can also use QuoteStringForSendKeys (QSfSK) to perform quoting.

Aliased Key Names

SendKeys('{BAC}'); # Backspace
SendKeys('{F1 F2 F3}'); # F1, F2, F3
SendKeys('{TAB 3}'); # Press TAB 3 times
SendKeys('{SPC 3 a b c}'); # Space 3 times, a, b, c

Special Functionality

# Pause execution for 500 milliseconds
SendKeys('{PAUSE 500}');

Combinations

SendKeys('abc+(abc){TAB PAUSE 500}'); # a, b, c, A, B, C, Tab, Pause 500
SendKeys('+({a b c})'); # A, B, C

The following abbreviated key names are currently recognized within a brace set.
If you don't see the desired key, you can still use the unabbreviated name for the
key. If you are unsure of this name, utilize the xev (X event view) tool, press
the key you want and look at the tools output for the name of that key. Names
that are in the list below can be utilized regardless of case. Ones that aren't
in this list are going to be case sensitive and also not abbreviated. For
example, using 'xev' you will find that the name of the backspace key is
BackSpace, so you could use {BackSpace} in place of {bac} if you really wanted to.

Name Action
-------------------
BAC BackSpace
BS BackSpace
BKS BackSpace
BRE Break
CAN Cancel
CAP Caps_Lock
DEL Delete

zero is returned on failure, non-zero for success. For configurations (Xvfb) that
don't support Alt_Left, Meta_Left is automatically used in its place.

PressKey KEY
Presses the specified key.

One can utilize the abbreviated key names from the table listed above as outlined
in the following example:

# Alt-n
PressKey('LAL'); # Left Alt
PressKey('n');
ReleaseKey('n');
ReleaseKey('LAL');

# Uppercase a
PressKey('LSH'); # Left Shift
PressKey('a');
ReleaseKey('a');
ReleaseKey('LSH');

The ReleaseKey calls in the above example are there to set both key states back.

zero is returned on failure, non-zero for success.

ReleaseKey KEY
Releases the specified key. Normally follows a PressKey call.

One can utilize the abbreviated key names from the table listed above.

ReleaseKey('n');

zero is returned on failure, non-zero for success.

PressReleaseKey KEY
Presses and releases the specified key.

One can utilize the abbreviated key names from the table listed above.

PressReleaseKey('n');

This function is affected by the key send delay.

zero is returned on failure, non-zero for success.

IsKeyPressed KEY
Determines if the specified key is currently being pressed.

You can specify such things as 'bac' or the unabbreviated form 'BackSpace' as
covered in the SendKeys information. Brace forms such as '{bac}' are unsupported.
A '{' is taken literally and letters are case sensitive.

if (IsKeyPressed('esc')) { # Is Escape pressed?
if (IsKeyPressed('a')) { # Is a pressed?
if (IsKeyPressed('A')) { # Is A pressed?

Returns non-zero for true, zero for false.

IsMouseButtonPressed BUTTON

Available mouse buttons are: M_LEFT, M_MIDDLE, M_RIGHT. Also, you could use the
logical Id for the button: M_BTN1, M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all
available through the :CONST export tag.

if (IsMouseButtonPressed(M_LEFT)) { # Is left button pressed?

Returns non-zero for true, zero for false.

IsWindow WINDOWID
zero is returned if the specified window Id is not for something that can be
recognized as a window. non-zero is returned if it looks like a window.

IsWindowViewable WINDOWID
zero is returned if the specified window Id is for a window that isn't viewable.
non-zero is returned if the window is viewable.

IsWindowCursor WINDOWID CURSOR
Determines if the specified window has the specified cursor.

zero is returned for false, non-zero for true.
