Hi all,
does anyone know a gnustep example application that builds under
MacOS with gnustep make and that correctly sets up the necessary
plist files (or whatever has to be done) to link file extensions
to application so that a doubleclick on a document file in Finder
automatically lauches the corresponding application?
I have written an app that should act as an editor for *.project
files. The linkage works under MacOSX 10.2 and GNUstep but not on
Leopard. Any idea?
I have found the following file in the application wrapper
pico /Applications/InterfaceBuilder.app/Contents/Info.plist
{
NOTE = "Automatically generated, do not edit!";
NSExecutable = "InterfaceBuilder";
NSMainNibFile = "";
GSMainMarkupFile = "";
CFBundleIconFile = "InterfaceBuilder.icns";
NSPrincipalClass = "NSApplication";
}
I modified that as follows
{
NOTE = "Automatically generated, do not edit!";
NSExecutable = "InterfaceBuilder";
NSMainNibFile = "";
GSMainMarkupFile = "";
CFBundleIconFile = "InterfaceBuilder.icns";
NSPrincipalClass = "NSApplication";
NSRole = "Editor";
NSTypes = (
{
NSUnixExtensions = ( "smib" );
NSIcon = "nibfile.tiff";
}
);
}
and Finder.app immediately had the connection between smib files
and InterfaceBuilder.app. Great!
Not great! This worked only after manually binding this one *.smib
file to /Applications/InterfaceBuilder.app using the Inspector Pane
of Finder.app. Trying to set the binding for all files with this
extension produced an undefined error message. I am still at the
beginning. What can I do to establish this binding with gnustep make
or any hacked file in the Contents folder of the application wrapper
on Leopard?
Is anybody (except me) actually using gnustep make on MacOSX 10.5?
Hints are still very welcome!
Andreas,
While I do use gnustep-make on OS X 10.5, I have not configured an
application as the default for specific document types as you are
trying to do. You may want to take a look at Apple's "Document-based
Applications Overview: Storing Document Types Information in the
Application's Property List" documentation:
http://developer.apple.com/documentation/Cocoa/Conceptual/Documents/Concepts/DocTypePList.html
Based on a quick glance at this document, it appears the changes you
manually made to Info.plist may not have the proper keys. If you use
the keys mentioned in the above document and follow Richard's
suggestion of putting your customization into XXXInfo.plist (with XXX
being the name of your application), hopefully things will work as you
desire.
Also, Apple is moving towards the use of Uniform Type Identifiers
(UTIs), instead of combinations of file extensions, type/creator
codes, etc. The following document gives some brief background on UTIs.
Uniform Type Identifiers Overview
http://developer.apple.com/documentation/Carbon/Conceptual/understanding_utis/index.html
I hope something from the above gets you going in the right
direction. Good luck!
Blake
