[Qt-interest] Problem setting extends value of qt plugins

[Simon Schäfer]

Hi everyone,

I have created a set of custom widgets which I use within the designer. One of 
the custom widgets is an enhanced Pushbutton which inherits from 
QAbstractButton, the designer now stores the custom Pushbutton in the ui file 
as extended from QWidget instead of QPushButtton. Is there a way to set the 
extend field within the ui file through the plugin code?

The major problem is as soon as someone who does not have the plugin is using 
the ui he can not modify the button text because its displayed as a widget, 
and has to manually edit the xml to set the extend field to QPushButton.

Example :
currently the button coming from the custom plugin is stored as below

<customwidget>
<class>CustomButton</class>
<extends>QWidget</extends>
<header>include/custombutton.h</header>
</customwidget>


and it should be something like the following to work on designers which are 
not using the plugin lib:

<customwidget>
<class>CustomButton</class>
<extends>QPushButton</extends>
<header>include/custombutton.h</header>
<container>1</container>
</customwidget>


Cheers 
Simon
