QMAKE_INFO_PLIST undocumented function

[patrik08]

To open documents on window i can catch on main arguments to open file.. this is ok...
And to set other extension to the new application i use the installer and if i click the document is open ok. super!

Now on mac after qt4 to drag document to the dock or open by normal click on finder the operation is more complicated....
On qt3 i found a sample hot to drag file on dock.. this link
http://doc.trolltech.com/qq/qq12-mac-events.html this method not run on qt4

on mac to associate my new doc type *.sdat i found on google this way:

on pro file i insert an other info.plist xml file to bring icon to new file type and to open application on finder by click the file.... this run ... the app start but a empty file is here.. and main arguments not work!

to find this Hack .. i open http://www.google.com/codesearch and i search QMAKE_INFO_PLIST && macEventFilter ... assistant not say nothing about this ...

QMAKE_INFO_PLIST = resource/mac_qedit.plist

<plist version="1.0">
<dict>
<key>CFBundleDevelopmentRegion</key>
<string>English</string>
<key>CFBundleDocumentTypes</key>

After i search / grep the qt4 source QMAKE_INFO_PLIST and i find the designer... and his associate ui file ok... now how designer open this ui file by click on finder or drag to dock from finder?

I found a designer server... , client ecc.. so much args...

    initialize();
}

    setWindowIcon(QIcon(QLatin1String(":/trolltech/designer/images/designer.png")));
#endif

    initialize();
}

But how designer open this ui file on MAC ? undocumented function?

Must i write a server and a client to open a new document type?


Or is here the event to open the file! and not QCoreApplication::.arguments();

bool QDesigner::event(QEvent *ev)
{
    bool eaten;
    switch (ev->type()) {
    case QEvent::FileOpen:
        // set it true first since, if it's a Qt 3 form, the messagebox from convert will fire the timer.
        suppressNewFormShow = true;
        if (!m_workbench->readInForm(static_cast<QFileOpenEvent *>(ev)->file()))
            suppressNewFormShow = false;
        eaten = true;
        break;
    case QEvent::Close: {
        QCloseEvent *closeEvent = static_cast<QCloseEvent *>(ev);
        closeEvent->setAccepted(m_workbench->handleClose());
        if (closeEvent->isAccepted()) {
            // We're going down, make sure that we don't get our settings saved twice.
            if (m_mainWindow)
                m_mainWindow->setSaveSettingsOnClose(false);
            eaten = QApplication::event(ev);
        }
        eaten = true;
        break;
    }
    default:
        eaten = QApplication::event(ev);
        break;
    }
    return eaten;
}

bool QDesigner::event(QEvent *ev)
{
    bool eaten;
    switch (ev->type()) {
    case QEvent::FileOpen:
        // set it true first since, if it's a Qt 3 form, the messagebox from convert will fire the timer.
        suppressNewFormShow = true;
        if (!m_workbench->readInForm(static_cast<QFileOpenEvent *>(ev)->file()))
            suppressNewFormShow = false;
        eaten = true;
        break;
    case QEvent::Close: {
        QCloseEvent *closeEvent = static_cast<QCloseEvent *>(ev);

I'm not sure if I understand correctly, but on Mac when you open a file from Finder ( or drag it to the app icon in the dock ), your app will receive a mac event ( no details, sorry ).
So you must reimplement macEvent and catch this event. In this event there are passed the action type( open ) and the file(s) name(s).

So it will not be a Qt event, but a mac event.

More info on developer.apple.com, probably in the window manager reference.

Oh, I have found it:

Why qt4.2 designer not use Apple Events , ui file go open and run....
to implement Apple Event on pro file must append LIBS += -framework Carbon
and designer not have it...

I like to open only file *.sdat on my app and the info.plist not have difined method open only mime apps ant tipe extension....

i suppode designer use an event like
http://doc.trolltech.com/4.2/qapplic...macEventFilter or event QEvent::FileOpen...

I understand only a smal piece of Cocoa objektiv C but Carbon it is an other pair of sleeves

[fullmetalcoder]

So it will not be a Qt event, but a mac event.

AFAIK Qt Designer uses QFileOpenEvent which is clearly said to be related with Finder actions (or whatever you call that... I'm not familiar with Mac...)

[patrik08]

I found its on qt4 no apple event are needet is comming all on normal event
on subclass QApplication && QCoreApplication no carbon ecc...

i write a LogEvents( const QString xml ) to see wathts of event go.... if i drag document to dock on graphics gui args on main is no needet i can catch all file on event window / mac / maybe linux is same....

all event from http://doc.trolltech.com/4.2/qevent.html#Type-enum can grab normal cross build.... QT4 is a Rolls-Royce Framework

Ok , i found it QEvent::FileOpen id 116 ,

you must not know or are familiar with Mac .. qt4 handle all os one same way ;
incredible .
on subclass QApplication you find event which you do not know that they exist..

Please read especially the one from QQ #12.

The QQ #12 is only to QT3 ... Issue 12 · Q4 2004 or QT4 was born on 2004?

I have write on wiki you see its? http://wiki.qtcentre.org/index.php?t...Mac_OSX_Finder

The method QApplication::event( QEvent *ev ) QEvent::FileOpen 116 open file on mac & window .. maybe Linux ... so on int main(int argc, char *argv[]) GUI version is not needed to grab file from argv .... only on console apps.... or QCoreApplication:event()..

I digested all http://www.google.com/codesearch && http://sourceforge.net/index.php QT4 filter code ; and i never found Apple Event only on QT3

[wysota]

The QQ #12 is only to QT3 ... Issue 12 · Q4 2004 or QT4 was born on 2004?

So? It explains the reason, idea and an example implementation. You don't have to copy the code.

I have write on wiki you see its? http://wiki.qtcentre.org/index.php?t...Mac_OSX_Finder

Yes, but we were wondering yesterday what this article is all about. You should rewrite the article and change its title to something more descriptive.

The method QApplication::event( QEvent *ev ) QEvent::FileOpen 116 open file on mac & window .. maybe Linux ... so on int main(int argc, char *argv[]) GUI version is not needed to grab file from argv .... only on console apps.... or QCoreApplication:event()..

Sorry, I don't understand what you want to say.

I digested all (...)

Was it tasty?
