QT4 custom designer plugin properties ignored

[jacek]

I was able to reproduce your problem and it seems that Designer gets confused when you have two plugins for widgets with the same class name.

Make sure:

• that the name of a class in XML snippet returned by domXml() and the string returned by name() are the same as the widget's class name,
• that there are no other plugins which name() method returns the same string (you might already have one plugin for AnalogClock widget installed),
• and finally that you compile your plugin in release mode.

Rename AnalogClock to something like AnalogClockX, update your plugin's code:

...
 
QString AnalogClockPlugin::name() const
{
        return "AnalogClockX";
}
 
...
 
QString AnalogClockPlugin::domXml() const
{
        return "<widget class=\"AnalogClockX\" name=\"analogClock\">\n"
               ...
               "</widget>\n";
}
 
...
 
QString AnalogClockPlugin::includeFile() const
{
        return "mycustom.h";
}

...

QString AnalogClockPlugin::name() const
{
        return "AnalogClockX";
}

...

QString AnalogClockPlugin::domXml() const
{
        return "<widget class=\"AnalogClockX\" name=\"analogClock\">\n"
               ...
               "</widget>\n";
}

...

QString AnalogClockPlugin::includeFile() const
{
        return "mycustom.h";
}

To copy to clipboard, switch view to plain text mode 

and run:

make -f Makefile.Release

make -f Makefile.Release

To copy to clipboard, switch view to plain text mode 

After this you should get a working plugin:

<customwidget>
 <class>AnalogClockX</class>
 <extends>QWidget</extends>
 <header>mycustom.h</header>
 <container>0</container>
 <pixmap></pixmap>
</customwidget>

<customwidget>
 <class>AnalogClockX</class>
 <extends>QWidget</extends>
 <header>mycustom.h</header>
 <container>0</container>
 <pixmap></pixmap>
</customwidget>

awesome
ok now at least i have a working example
i gotta figure out if this is what could be causing my issue with my custom widgets in my collection

they are having issues too but they have unique names


im going to try and alter this example code to use a collection and see if all of the widgets in the collection work. or not

now i have a working plugin to experiment off of though!

thanks jacek!

This doesnt work. 100%

QWidget *TestPlugin::createWidget(QWidget *parent)
{
    return new CustomControls::CheckBox(parent);
}
 
QString TestPlugin::name() const
{
    return QLatin1String("CheckBox");
}
 
QString TestPlugin::domXml() const
{
    return QLatin1String("<widget class=\"CustomControls::CheckBox\" name=\"cb\">\n"
                         "</widget>\n");
}
 
QString TestPlugin::includeFile() const
{
    return QLatin1String("checkbox.h");
}

QWidget *TestPlugin::createWidget(QWidget *parent)
{
    return new CustomControls::CheckBox(parent);
}

QString TestPlugin::name() const
{
    return QLatin1String("CheckBox");
}

QString TestPlugin::domXml() const
{
    return QLatin1String("<widget class=\"CustomControls::CheckBox\" name=\"cb\">\n"
                         "</widget>\n");
}

QString TestPlugin::includeFile() const
{
    return QLatin1String("checkbox.h");
}

it gives me

<customwidgets>
<customwidget>
<class>CustomControls::CheckBox</class>
<extends>QWidget</extends>
<header>customcontrols::checkbox.h</header>
</customwidget>
</customwidgets>

and it doesn't matter what you return in function includeFile(). Header file been generated automatically from widget class
