Hi!
I am trying to use the Qt cross-platform framework
(www.trolltech.com) to build aplications for Windows and OSX, and
possibly Linux.
One problem with this is that Windows (and Linux?) is using
main(argc, argv[]) to pass the result of dropping-on-app or
document double-click to the application to open the documents,
while OSX does not.
Please correct me if I am wrong.
So document double-click or drop-on-app just launches the OSX
application, but does not open any documents.
Again, please correct me if I have missed something.
I have tried to use an applescript "droplet" to collect the drop
input list and then pass this to the application, and this actually
works.
However, I do not know how to set this up correctly when combining
the droplet executable and the Qt executable into the same bundle.
I want to set the path to the Qt app in the droplet script so that
it finds it properly.
Here is a script that works, but it is of course useless because of
the absolute path I used for testing:
on idle
(* Add any idle time processing here. *)
set j51command to "/Users/bnilsson/Programming/Qt/J51Viewer/
build/
Debug/J51Viewer.app/Contents/MacOS/J51Viewer"
do shell script j51command
quit
end idle
on open names
(* Add your script to process the names here. *)
set j51command to "/Users/bnilsson/Programming/Qt/J51Viewer/
build/
Debug/J51Viewer.app/Contents/MacOS/J51Viewer " & POSIX path of
names
do shell script j51command
-- Remove the following line if you want the application to stay
open.
quit
end open
Any comments or suggestions?
Yes. Read more about developing Mac software before trying to write
Mac software. You're using a shell script to do something Macs were
doing long before you could run shell scripts on them. Look at some
of Apple's sample applications. Many of them handle files that are
dragged to their icons.
Thanks for your friendly advice.
I am NOT trying to write a Mac application as such, I am trying to
use
a cross-platform framework with the facilities it offers.
Of course I would write it differently if Mac was the only target.
And I'm pretty sure this a programming question, not an Xcode
question, so carbon-dev or cocoa-dev would be a more appropriate
place for these kinds of questions. Actually, this sounds like a Qt
question. Opening a file by dragging it to an application is a
common practice on a Mac, so I'd be surprised if Qt didn't supply a
way to do this that you just need to hook into somehow. Someone on
carbon-dev may know, although most of us on that list haven't used
Qt.
Qt does not support you if you don't have a contract.
They supply a open-source download and license but then you're on
your
own.
I have had this question on their user forum for about a week now
without a good answer, that's why I am here.
I am very sorry I have taken up your time, and yes, I agree it is a
bit off-topic in this list..
