[WIP] alternative MenuLauncher/TaskSwitcher (telescope) for Fremantle

Telescope was primarily made for Diablo [http://talk.maemo.org/showthread.php?t=58691] to mimic Fremantle's TaskSwitcher and MenuLauncher (which are part of hildon-desktop).

This is attempt to port it to the Fremantle. Source code for (not yet merged) Fremantle-branch: https://bitbucket.org/aaporantalainen/telescope

Install from extras-devel: telescope (not fully optified, uses 131K of rootfs).
Start manually by typing telescope .Root access not needed.

Video: http://youtu.be/WcmFiwmA3JM

Status: it works. Some crashing when closing xterm (unstable). Cosmetic issues. Needs modifications for hildon-desktop (until it is useful).

Code:

Features (what is working / what is expected behaviour currently):

*If no application running, CTRL+backspace => Launcher

*If Switcher is running, CTRL+backspace => Launcher

*Launcher: starting application

*Launcher: show notification when application starts

*Launcher: scrolling list with finger

*Launcher: scrolling list with keyboard (arrows)

*Launcher: build-in categories (currently only 'main'). Long press title to change icon.

*Launcher: show another catory with keyboard (arrows)

*Launcher: landscape/portrait

*Launcher: cancel (press empty area)

*Launcher: cancel (press unused key from keyboard)



*If one or more application running,  CTRL+backspace => Switcher

*Switcher: switching to selected application

*Switcher: cancel (press empty area)

*Switcher: killing application

*Switcher: landscape/portrait.

*Long press: CTRL+backspace => show desktop





Issues:

*CTRL+backspace also starts TaskSwitcher from hildon-desktop (below Telescope's Switcher)

*Launcher: Categories panel doesn't support portrait

*Switcher: background for portrait missing

*Launcher: localization of shortcut names messed

*Switcher: killing one xterm terminates all xterms (might happens also with another multi instance applications)

*Launcher: can't use Fn+arrow (because Fn causes cancel immediately)

*Launcher: some icons scaled wrongly

*Button on hildon panel starts switcher/launcher from hildon-desktop



Todo:

*autostart during boot

----
Is there any point?
-There were reports that hildon-desktop is hogging CPU. Maybe we can get rid of whole (or partly) hildon-desktop.
-Hildon-desktop is only piece which is using closed source graphics driver.

I personally would be very happy if we had a hildon-desktop alternative (desktop, launcher, task manager) with full keyboard control (please fix that fn-key issue, I also have only 2 arrow keys :)

I just like using the keyboard, and find it (still) cumbersome to have to press with my finger somewhere, where a key would suffice. (I guess I'm old fashioned :)

Re: [WIP] alternative MenuLauncher/TaskSwitcher (telescope) for Fremantle

i would like to c android ICS way of closing an app(swiping left/right to close an app)in the same way like moving a window up/down to close it.. that would best suit our N900's instead of those droids.. ;)

Again, I may be old fashioned, but I find tapping on an "X" to kill an application infinitely more intuitive than swiping anything in any direction.

Code is not c++11. My compilers do not know -Wnarrowing. I think dropping -Werror is enough. Now I added (and pushed) "-std=gnu++98" to the Makefile_desktop. Is there some side effects for that?

EDIT: Would this be better? -std=c++98

Re: [WIP] alternative MenuLauncher/TaskSwitcher (telescope) for Fremantle

thanks. can anyone upload this video on metacafe as youtube is blocked in my country ? and some screenshots please.

to the Makefile it still shows errors but the telescope works:D

Add

Code:

#include <unistd.h>

to the MenuReader.cpp (and report next issue. I didn't yet check compiling with gcc-4.7)
