Hi,
I am playing around with a small app launcher hack -- PhlegmHack/McPhling -- with the
intention of extending it. The idea is to patch SysAppLaunch so as to be able to save
previously launched app in a MRU list and thus be able to launch them again from a
small popup menu. I want to add the ability to launch apps from an expansion card in
the same way.
There are two problems here that I have stumbled over: (1) How to actually launch an
app from the card, and (2) how to find from within the SysAppLaunch call that an app
has been launched from a card so I can store the details.
I have no idea how the built-in Launcher manages (1), so any hints as to where to look
are appreciated. SysUIAppSwitch just takes a database ID as parameter, so I suspect
that I will have to copy the database to RAM first, but am I supposed to delete it as
well? I did think at first that the Launcher would set the dmHdrAttrRecyclable
database attribute, thus rendering the application database open for automatic
deletion after execution.
This was my approach for (2); check for dmHdrAttrRecyclable on the current database.
This does not seem to be the case however; the app has all the normal database
attributes that you would expect, and it gets deleted after execution anyway. It would
be nice to know exactly what the Launcher does; it seems to be fairly magic in its
implementation... ;-)
I have tried to be a good boy and searched the archives several times, as well as the
KB. I asked this question a week ago, but have not seen any response so far. Have I
nevertheless missed something, would I appreciate a pointer and beg forgiveness for
wasting your time.
Cheers!
