Unable to load custom widgets in UI file with QUiLoader

[graphicsRat]

I'm trying to use QUiLoader to load a UI file that contains a custom widget resident in a path, which I have registered with QUiLoader as shown below. Yet QUiLoader is unable to find the my plugin.

QUiLoader loader;
loader.addPluginPath( "folder/containing/MySnazzyWidgetDll" );
QStringList paths = loader.pluginPaths();  // returns path to plugin

QStringList availableWidgets = loader.availableWidgets();
if( availableWidgets.contains( "MySnazzyWidget" ) )
{
    QFile file( "File.ui" );
    file.open( QFile::ReadOnly );
    QWidget* widget = loader.load( &file );
}
else
{
    LOG_ERROR << "Unable to instantiate MySnazzyWidget";    // ALWAYS
    return;
}

I'm not even sure what sort of plugin that's supposed to be loaded. A designer plugin or a widget plugin i.e. a widget class compiled as a DLL.

Please advise.

Thanks.

Hi and welcome to devnet,

I can't answer for the plugin part however "folder/containing/MySnazzyWidgetDll" is a relative path so are you sure that the plugin is searched ?

On thing you can do to check that is to run your application with QT_DEBUG_PLUGINS=1

Hope it helps
