Custom widget not visible in Integrated designer of Qt Creator

[John82]

There could be many reasons for this.
1. Your plugin is not properly exported, please refer the code of Analog clock for example.

-- If the plugin is not exported properly, Does it still show up in the plugin information ?

2. In doXML function of your plugin class, try to change the group and other properties.

-- I commented out this section to return only a simple string. I will see if that was causing the problem.

Yup! It was because I had commented out the code in domXml (). The plugin became visible. After this there was a small problem because because the actual widget itself wasn't displayed when I dropped it into a form. In the terminal, I got this message :

Designer: The class attribute for the class MyClock does not match the class name NewPlugin.
Designer: A class name mismatch occurred when creating a widget using the custom widget factory registered for widgets of class NewPlugin. It returned a widget of class MyClock.

I went through the code again and realized that the name () was returning the name of the plugin class rather than the widget class. I changed this and everything started working properly. Thanks!
