Device::ParallelPort, so it should be able to run on Linux now too.
0.6 AAC::Pvoice::Bitmap now returns a wxNullBitmap if the resize-factor
is 0 to prevent 'illegal division by zero'
AAC::Pvoice::EditableRow now has some sensible defaults to prevent
'Use of uninitialized value' warnings
AAC::Pvoice::Input can now handle one button input
0.7 AAC::Pvoice::Input
* now allows keyboard input
* now allows direct mouseclicks on the buttons
AAC::Pvoice::Panel
* now uses a round cornered background and
* no longer simply sets the background for the normal and
selected state, but draws a round cornered border around
the rows and buttons that are selected
* finally got the screensizing correctly...no more weird
calculating stuff...
AAC::Pvoice::Bitmap
* now produces round cornered bitmaps
AAC::Pvoice::Row
c) If the modified program normally reads commands interactively when run, you
must cause it, when started running for such interactive use in the most ordinary
way, to print or display an announcement including an appropriate copyright
notice and a notice that there is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program under these conditions,
and telling the user how to view a copy of this License. (Exception: if the
Program itself is interactive but does not normally print such an announcement,
your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Program, the distribution of the whole must be on
the terms of this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to
work written entirely by you; rather, the intent is to exercise the right to control
the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the
Program (or with a work based on the Program) on a volume of a storage or
distribution medium does not bring the other work under the scope of this
License.
3. You may copy and distribute the Program (or a work based on it, under
Section 2) in object code or executable form under the terms of Sections 1 and 2
b) Accompany it with a written offer, valid for at least three years, to give any
third party, for a charge no more than your cost of physically performing source
distribution, a complete machine-readable copy of the corresponding source
code, to be distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for noncommercial
distribution and only if you received the program in object code or executable
form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making
modifications to it. For an executable work, complete source code means all the
source code for all modules it contains, plus any associated interface definition
files, plus the scripts used to control compilation and installation of the
executable. However, as a special exception, the source code distributed need
not include anything that is normally distributed (in either source or binary form)
with the major components (compiler, kernel, and so on) of the operating system
on which the executable runs, unless that component itself accompanies the
executable.
you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of this
License. If you cannot distribute so as to satisfy simultaneously your obligations
under this License and any other pertinent obligations, then as a consequence
you may not distribute the Program at all. For example, if a patent license would
not permit royalty-free redistribution of the Program by all those who receive
copies directly or indirectly through you, then the only way you could satisfy
both it and this License would be to refrain entirely from distribution of the
Program.
If any portion of this section is held invalid or unenforceable under any particular
circumstance, the balance of the section is intended to apply and the section as
a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other
property right claims or to contest validity of any such claims; this section has
the sole purpose of protecting the integrity of the free software distribution
system, which is implemented by public license practices. Many people have
made generous contributions to the wide range of software distributed through
that system in reliance on consistent application of that system; it is up to the
author/donor to decide if he or she is willing to distribute software through any
other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries
either by patents or by copyrighted interfaces, the original copyright holder who
places the Program under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is permitted
only in or among countries not thus excluded. In such case, this License
incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the
lib/AAC/Pvoice/Input.pm view on Meta::CPAN
on Win32 as well as Linux platforms.
=head1 USAGE
=head2 new($window)
This constructor takes the window (AAC::Pvoice::Panel typically) on which
the events and timer will be called as a parameter.
If the configuration (read using Wx::ConfigBase::Get) has a key called
'Device' (which can be set to 'icon', 'keys' , 'mouse' or 'adremo') is set to 'adremo', it
will start polling the parallel port every x milliseconds, where x is the
value of the configuration key 'Interval'. This setting is only useful if you connect
an "Adremo" electrical wheelchair to the parallel port of your PC (for more
information see http://www.adremo.nl).
If the key 'Device' is set to 'icon' it will respond to the left and right
mouse button, and if it's set to 'keys' it will respond to the configuration
keys 'SelectKey' and 'NextKey' (which are the keyboard codes for the 'select'
and 'next' events respectively.
AAC::Pvoice::Input has the ability to operate with either one or two buttons.
If you want to use only one button, you need to set the configuration key "Buttons"
to 1, and it will automatically invoke the subroutine you pass to Next()
at an interval of the value set in the configuration key OneButtonInterval (set in milliseconds).
The default for is to operate in two button mode, and if OneButtonInterval is not
set, it will use a default of 2000 milliseconds if "Buttons" is set to 1.
=head2 newchild($window)
This semi-constructor takes the window (usually a child of the panel you
passed to the new() constructor, on which the events will be called as a parameter.
It doesn't start the timers for polling the parallel port and automatic
invocation of the Next() subroutine, because those timers otherwise would
be started multiple times.
Apart from starting those timers, this method works exactly like the new()
lib/AAC/Pvoice/Input.pm view on Meta::CPAN
=head2 GetDevice
This method will return the value of the configuration key called 'Device'
=head2 SetupMouse($window, $subgetfocus, $subup, $sublosefocus)
This method is used to setup a button for normal mouse input (when
configuration key 'Device' is set to 'mouse'). It takes the wxWindow
(typically a Wx::BitmapButton) that should respond to this way of
input as the first parameter.
$subgetfocus is the coderef that should be invoked when the mousecursor
hovers over this $window (EVT_ENTER).
$subup is the coderef that should be invoked when the left mousebutton
is released (EVT_LEFT_UP).
$sublosefocus is the coderef that should be invoked when the $window
loses focus (EVT_LEAVE).
=head2 StartMonitor
This method will start polling the the parallel port for input of the Adremo
Electrical Wheelchair.
lib/AAC/Pvoice/Input.pm view on Meta::CPAN
This method will stop the timer that monitors the parallel port.
=head2 PauseMonitor($bool)
This method will pause ($bool is set to 1) or restart ($bool is set to 0)
the timer that monitors the parallel port.
=head2 StartAutoscan
This method will start the timer that invokes the Next() event every n milliseconds.
=head2 QuitAutoscan
This method will stop the timer that invokes the Next() method.
=head2 PauseAutoscan($bool)
This method will pause ($bool is set to 1) or restart ($bool is set to 0)
the timer that invokes the Next() method.

for those parameters.
=over 4
=item disabletextrow
This is s a boolean (1 or 0), which determines
if the text-input field at the bottom of the screen should be hidden or
not. Normally this inputfield will be shown (for an application like pVoice
this is normal, because that will contain the text the user is writing),
but for an application like pMusic this row is not nessecary, so it can be
disabled.
=item itemspacing
This is the spacing used between the rows that are appended.
=item selectionborderwidth
This is the width of the border around a selected row or a selected item.
lib/AAC/Pvoice/Panel.pm view on Meta::CPAN
=head2 Select
This method normally won't be called directly either. It will either 'select'
the row that is highlighted and thus go into columnselection, or, when we're
in columnselection, invoke the callback associated with that item and
go into rowselection again.
=head2 ToRowSelection
This method will remove the highlighting of an item (if nessecary) and highlight
the entire current row again and set rowselection back on.
=head2 DisplayAddText(text)
In pVoice-like applications there's a difference between 'displaytext' (which is
the text that the user actually is writing and which should be displayed on the
textrow) and the speech (phonetical) text (which is not displayed, but -if nessecary-
differs from the text as we would write it, so a speechsynthesizer sounds
better.
This method adds text to the displaytext. It is saved internally and displayed
on the textrow
=head2 SpeechAddText(text)
This method add text to the speechtext. It is saved internally and not displayed
on the textrow. See DisplayAddText for more information.
