    Info.plist to *open* a file
    Hi all,

    I do some development for an open source project called KeePassX (, which is built on top of the Qt platform. Up until recently we just let it automatically generate the Info.plist file but the file was insufficient so I have changed the profile (basically like a Makefile for Qt) and have it use an Info.plist file that I manually generated.

    This is a vast improvement and one really nice thing about it is that double-clicking on a file now launches KeePassX. Furthermore, the files associated with KeePassX (.kdb files) all have the proper icon on them as well.

    The problem is that double-clicking on a file only launches KeePassX, but it doesn't actually open the file once the application has launched. You still need to either press command+O or go to File -> Open database to actually get the program to open the file. Does this mean that I'm missing something from the Info.plist file?

    Certainly this behavior is undesirable. When I click on a file with the extension .doc it launches Microsoft Word and then opens the document. It would be silly for it to launch Word and then still have to go to File -> Open in order to open the document that I had just double-clicked on; yet this is how KeePassX is currently behaving.

    Below is the Info.plist file (taken from SVN revision 297 if you happen to checkout the code). Any ideas are appreciated as we are about to release version 0.4.0 and I was really hoping to have this fixed. Our Linux version now properly associates itself with .kdb files and it will properly open them when a database file is double-clicked. I would like to get the Mac release working as well. Thanks!

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "">
    <plist version="1.0">
        <!-- For a full list of properties, see
        <string>KeePassX 0.4.0</string>
            <string>KeePassX Password Database</string>

    Here is an update. I put some debug statements into the code and compiled it. If I launch the code from the command line by specifying the binary directly then it prints out the correct argument (and even correctly opens the application AND the file, like I would expect it to):

    adamwest:keepassx bmayes$ /Applications/ ~/Documents/Example.kdb 
    However, if I use the open command from terminal it doesn't print anything and doesn't open the file -- it just opens the application and never opens the file:

    adamwest:keepassx bmayes$ open ~/Documents/Example.kdb 
    adamwest:keepassx bmayes$
    I think this might have something to do with the fact that it's using the Cocoa framework and actually calling the application::openFile function instead of passing the name of the file as an argument to argv?

    I haven't played with that so I Googled it found this at O'Reilly.

    There might also be the need to register the file extension with an application.
    This link discusses that. In fact this may be the better link of the two.

    Nevermind, we were able to get it working without using the Info.plist file. Thanks for looking though.
