How to compile qtwebkit-plugins?

SGaist

Hi,

You should run your application with the QT_DEBUG_PUGINS environment variable set to 1 to see if the plugins are found and if they encounter a problem loading. You can do that in the run part of the Project panel

Hope it helps

Thanks, I added in Project > Build Environment this var QT_DEBUG_PLUGINS = 1 and work, returning this:

But it not show qtwebkitplugins.dll in the log.

How can I solve this issue?

Just thought of something, why didn't you call mingw32-make install ?

Also did you enable the plugins in the QWebSettings of your application ?

Thank you for your dedication,

As silly as it may sound, just go in the same folder where you built the plugin and call mingw32-make install unless make has an other name on your system ?

After I tried this command mingw32-make && mingw32-make install, return this:

I copied .dll and .a generated for mingw folder and tested my project with webview (with QT_DEBUG_PLUGINS = 1).

If have focus in <input type="text"> or <textarea> or use Notification Web API Application output tab (in QtCreator) returns:

Found metadata in lib C:/Qt5.4.0/5.4/mingw491_32/plugins/webkit/qtwebkitplugins.dll, metadata=

    "IID": "org.qtwebkit.QtWebKit.QtWebKitPlugin",
    "MetaData": {
    },
    "className": "QtWebKitPlugin",
    "debug": false,
    "version": 328704
}


loaded library "C:/Qt5.4.0/5.4/mingw491_32/plugins/webkit/qtwebkitplugins.dll"
QLibraryPrivate::unload succeeded on "C:/Qt5.4.0/5.4/mingw491_32/plugins/webkit/qtwebkitplugins.dll" 
QSystemTrayIcon::setVisible: No Icon set

It seems to me that the .dll is loaded, it just is not working. What did I do wrong?

I solved

For this work in QT5.4+ is necessary to modified the qwebkitplatformplugin.h file

Change this:

QT_BEGIN_NAMESPACE
Q_DECLARE_INTERFACE(QWebKitPlatformPlugin, "com.nokia.Qt.WebKit.PlatformPlugin/1.9");

By this:

QT_BEGIN_NAMESPACE
Q_DECLARE_INTERFACE(QWebKitPlatformPlugin, "org.qt-project.Qt.WebKit.PlatformPlugin/1.9");

If needed compatibility with QT-4.8 change the code for this:

QT_BEGIN_NAMESPACE
#if QT_VERSION >= 0x050200
Q_DECLARE_INTERFACE(QWebKitPlatformPlugin, "org.qt-project.Qt.WebKit.PlatformPlugin/1.9")
#else
Q_DECLARE_INTERFACE(QWebKitPlatformPlugin, "com.nokia.Qt.WebKit.PlatformPlugin/1.9")
#endif
QT_END_NAMESPACE

I send a pull-request https://github.com/QupZilla/qtwebkit-plugins/pull/4 in repository

Good catch !

Thanks for sharing your findings.

One last thing to do is mark the thread as solved so other forum users may know as solution has been found :)

How to do it? Nothing appears but the editing buttons and sharing on social networks.

Thanks.

SGaist

Don't you have somewhere on the page a "Mark Solved" button ? Or Topic Tools -> Mark Solved ?

@SGaist No, I migrated my account "qt-project.org/" and I think merge it with the account that already existed in "qt.io", perhaps the account has not been fully active.

I discovered, your account is moderator type (I think), my account is a normal user, so I'm not such a function, but @tekojo had an idea to use "tags" instead of this function, see: https://bugreports.qt.io/browse/QTWEBSITE-631
