Apple Remote Implementation for OpenOffice.org Aqua on Mac OS X

Description

1. This may be a bug in Mac OS X 10.3.x and 10.4.x which cannot be solved by OpenOffice.org developers. There are two known solutions: Even though the Finder has problems with passed through downloads from Safari the download often works when you copy the download url to the clipboard, switch to the Finder-Go-Connect to Server and paste the url.
2. The Free and Open Productivity Suite. Apache OpenOffice 4.1.7 released. Product; Download; Support; Blog; Extend; Develop; Focus Areas.
3. Get the latest Apache OpenOffice release for your MacOS X. Please subscribe to the users mailing list. Send an empty email to users-subscribe@openoffice.apache.org and just reply to the returned email. News and weblog. Recent news articles from the Apache OpenOffice homepage.

As part of native OpenOffice.org for Mac OS X, a Quicktime backend for avmedia module will be created, to support native audio and video on Mac OS X. Although this implementation concentrates on Mac OS X, it should be possible to make Quicktime backend work on Windows-platform too. OOo scope: avmedia module. OpenOffice.org is the result of over twenty years' software engineering. Designed from the start as a single piece of software, it has a consistency other products cannot match. OpenOffice.org is easy to learn, and if you're already using another office software package, you'll take to OpenOffice.org straight away.

The remote, on the above picture, allows to drive applications in fullscreen mode, or in windowed mode, for playing presentations, photos slideshows, play music .. and so on, with the latests computers Apple ships, including Intel processors, but not only.

The most known application running with the remote, is Front Row

There is at least one model running PowerPC processor, the iMac G5 iSight, who is shipped with a remote too.

More information : Apple Remote on Wikipedia

Goal

Several steps are scheduled (appleremote01, appleremote02 and appleremote03)

Timeline

Task started early june 2008

Source Code authors

Initial code who allows the Apple Remote control use, has been written by from Martin Kahr, under the MIT License. This code, who has been put in the new apple_remote module, has been adapted to OpenOffice.org by Eric Bachard, under the same license.

For further informations, please see : Martin Khar website

Important: to make it work with OpenOffice.org , the initial code in the cws has been modified a lot. Please use the original code if you want to see the diffs

Note: the existing code allows to use the Keyspan remote device. If you have such device, please provide us feedback and help us to make it work

Modes (definitions)

The current implementation is described below. If you have a better idea (not too complicated though), please tell us.

1) Mode not presenting

This mode means, windows and frames are displayed.

If you have choosen to run the prosentation in Windowed mode, the remote works like if you are in fullscreen (since appleremote02)

Else, just play will work, and start the presentation in fullscreen.

2) Mode Presentation

Starting point: fullscreen, slide 1 is displayed, presentation paused (default). From presentation mode, can be reached any slide, using the menu (used as a right click)

Or :

The current window has been extended in all the screen (using CTRL+shift +J), just hidding the window , borders,the menubar and the dock.

This is a window-less mode, aka fullscreen mode, known as the usual mode for presentation.

3) LIST_MODE (will be implemented in appleremote03)

=> DRAFT

What follows is just a draft: means there is no guarantee it will work as expected, and will need a lot of tests.

Expected behavior: in list mode or in menu mode: [right], [left], [+] or [-] buttons allow to browse the contextual menu

Important : this feature works in parallel with other events from mouse or keyboard

To trigger the contextual menu :

Hit menu key when on fullscreen (during the presentation) :

• pauses the presentation
• makes the contextual menu appear

Hit the menu key entry again or escape :

• removes the contextual menu
• resumes, and the presentation continues

To navigate :

Hit the - key goes down in the menu when possible

Hit the +key goes up in the menu when possible

Hit the right (forward) key goes right in the menu when possible

Hit the left (backward) key goes left in the menu when possible

To validate an item :

Hit the key play/pause, in LIST_MODE, means when a menu appears, or type enter :

• validates the highlighted menu item, when corresponding to an existing possibility

4) Other mode : Presenter Screen extension

This is not a mode, but more a feature, allowing you to read your notes on the laptop, while the slides are displayed .. etc

Download the extension, install it, and in the diaporama properties, don't forget to choose screen 2 for the presentation screen (else you'll see the presenter screen on the public screen and the presentation on your laptop / screen :-)

Other definitions

short key stroke: short key hit, inferior to 0,4 second

long key stroke: obtained when the key is maintained hit more than 0,4 second

Detailed behavior after appleremote02 will be integrated (Draft)

Mode not presenting (aka Windowed mode)

Either :

and if the Windowed mode is selected in the preferences :

else :

Hit the Play button will start the presentation at the current slide (common use)

Or:

TODO

Mode Presentation

• Hit Page backward ( |<< symbol ) or + button ( Volume down) gives Previous page (if existing)

• Hit Page forward ( >>| symbol) or - button (Volume up) gives Next page (if existing)

• longHit Page backward ( |<< symbol ) gives First page

• long Hit Page forward ( >>| symbol) gives Last page

• Play : toggle play/pause button can play pause automatic presentation

Other PRESENTATION_MODE FEATURES

1) + / - button can increase / decrease sound volume (very unsure, because some Apple black magic seems to lock that buttons)

2) Hit menu key simulates right click -> gives the contextual menu in presentation mode => opens the LIST MODE

3) hold play (long hit) allows to choose a list of presentations, in some default dir (like Front Row does) )

4) in LIST_MODE (available in presentation mode only)

• normal stroke: [right], [left], [+] or [-] browses the contextual menu
• play validates the choice ( ends the LIST_MODE )
• stroke menu : simulates escape and ends the LIST_MODE

Note: go to the first/last slide can be achieved using the contextual menu

Technical part

Make it buildable

Done. With the current code, no warnings, everything is delivered as expected.

• in apple_remote module (build triggered in postprocess)
• in vcl : apple_remote module has been added as a dependancy
• in scp2 ( libAppleRemotemx{i | p}.dylib has been added in the package

Integrate the code in OpenOffice.org for Mac OS X

Done :

Concerned modules :

Openoffice Org For Mac Osx

• external (Apple Remote code will be there due to the MIT License )
• scp2 : libAppleRemotemxi.dylib has to be packaged
• vcl : MainControler object and notifications are detected by the NSApplication in all its life + add apple_remote module as dependancy
• postprocess : build apple_remote module
• sd : implement the MEDIA_COMMAND part, add the eventListener, remove it, and add missing features

Code :

• created external/apple_remote tree. To check out the module (until it is integrated) : cvs co apple_remote
• created the makefile, links against IOKit framework
• modified prj/build.lst to build external/AppleRemote
• modified prj/d.lst to deliver the headers in the solver (vcl will need them) and deliver libAppleRemotemxi.dylib
• build is ok : no warning (fixed the static issue, and all the other warnings , made the code more robust)
• in vcl : modified the makefile ( linking against libAppleRemotemxi.dylib ), added mpMainController member in SalData ( saldata.hxx ),

initialized mpMainController in the SalData Ctor, added the MainController initialization in initNSApp() (salinst.cxx)

• release mpMainController in saltada destructor
• Packaging works as expected, and OpenOffice.org works fine with the new lib included in the archive

Done :

Remote Control initialized, and reports finely all events.

Global Keyboard works

Multi click should work too

Current logs :

Important:

The remote is active when one OpenOffice.org window has the focus. Using the Finder ( Apple + TAB ) deactivates it, and then Front Row becomes again available. The OpenOffice.org application no longer receives the events when Front Row is active.

Select another application gives :

Note: the keys are extracted from the userInfo dictionary

Select again OpenOffice.org in front gives:

TODODONE :

• alias for apple_remote in external created by Martin Hollmichel (see issue 92739 )
• code commited
• cws appleremote01 created ( Florian Heckl will QA it)
• all known issues fixed. Remains: better keycode mapping
• final design for final implementation in progress

Needed:

• infos about contextual menu emulation
• feedback for the Keyspan remote
• feedback for the current Design

Intercept events with the remote, and trace

Adding some NSLog at the right place, we have the numerical values returned by the remote:

• + as value '2'
• - is seen as value '4'
• Menu button is seen as the value '8'
• |> || (play pause) as value '16'
• >>| is seen as value '32'
• <<| is seen as '64'
• long hold with key Menu (kRemoteButtonMenu_Hold) is seen as value '512'
• long hold with key Play (kRemoteButtonPlay_Hold) is seen as value '1024'
• long hold with key Backward (kRemoteButtonLeft_Hold) is seen as value '2048'
• long hold with key Forward (kRemoteButtonRight_Hold) is seen as value '4096'

Important: when in Front Row mode, the events are seen too, and accordingly to the link below, there is a way to programaticaly enable / disable it.

Do not work :

• long hold with key Plus (kRemoteButtonPlus_Hold) is seen as value '128'
• long hold with key Minus (kRemoteButtonMinus_Hold) is seen as value '256'

Added kRemoteButtonNone, for button initialization

Started :

vcl bindin using ImplHandleAppCommand()

Missing (to be added ?) :

// Missing : case kRemoteButtonMenu:

case kRemoteButtonMenu_Hold:

case kRemoteButtonPlay_Hold:

case kRemoteButtonRight_Hold:

case kRemoteButtonLeft_Hold:

case kRemoteControl_Switched:

break;

Done :

case kRemoteButtonPlay

case kRemoteButtonLeft

case kRemoteButtonRight

case kRemoteButtonMinus

case kRemoteButtonPlus

TODO :

• bind with vcl events
• make it work
• improve
• make it work also with OOo Presenter extension

XSlideShowController use

• Since another solution has been used, what follows it there for information, as developer note

Philipp Lohmann presented me Andre Fisher, the specialist of the thing. Andre kindly explained me where start :

From Andre mail :

bind with vcl events

=> DONETODO

First basic implementation works :

• play
• quit presentation mode
• next slide
• previous slide
• first slide
• last slide
• up : volume up does not work with the current implementation, but is replaced with previous slide
• down: volume down does not work with the current implementation, but is replaced with next slide

Missing :

• contextual menus

Make it work

=> DONETODO

Create the cws and commit

DONE: file the issue, and ask mh the alias to be created. (maybe things are more easy now ?)

Improve

• Did Apple document the API since ?
• Document how things are working [started]
• Does an Impress Controller API exist ?
• Find where the events are managed in slideshow (or sd) ? [ask Thorsten]
• Contact Andre Fisher, the specialist of the thing (following Philipp Lohmann recommandations), and see how marry the remote with the presenter screen

Using different devices

Right now the wrapper ships with support for three devices:

• [works] AppleRemote: Apple Remote Control
• [works] GlobalKeyboardDevice: Registers global keyboard shortcuts to provide a virtual remote control
• [untested, no feedback yet] KeyspanFrontRowControl: Keyspan RF Remote for FrontRow
