How to subclass a control in *.ui?

[jrideout]

Sorry my solution is for Qt4, I just noticed you are using Qt3.

Anyway for folks that read this thread and are using 4 here is a clarification.

In designer, with your form open, right click the widget in the form.

The context menu from right clicking should look like this:

Change objectName
Change toolTip
Change whatsThis
------------------
Promote to Custom Widget
------------------
Cut
Copy
...

Change objectName
Change toolTip
Change whatsThis
------------------
Promote to Custom Widget
------------------
Cut
Copy
...

To copy to clipboard, switch view to plain text mode 

Select "Promote to Custom Widget". A dialog will appear where you can put in the name of the derived class and a header that defines it.

You can edit the ui manually to achive the same effect. Try something like this:

<ui version="4.0" >
 <class>Dialog</class>
 <widget class="QDialog" name="Dialog" >
  <property name="windowTitle" >
   <string>Dialog</string>
  </property>
  <widget class="QTableView" name="tableView" >
  </widget>
  <widget class="myCustomTable" name="customTableView" >
  </widget>
 </widget>
 <customwidgets>
  <customwidget>
   <class>myCustomTable</class>
   <extends>QTableView</extends>
   <header>mycustomtable.h</header>
   <container>0</container>
   <pixmap></pixmap>
  </customwidget>
 </customwidgets>
</ui>

<ui version="4.0" >
 <class>Dialog</class>
 <widget class="QDialog" name="Dialog" >
  <property name="windowTitle" >
   <string>Dialog</string>
  </property>
  <widget class="QTableView" name="tableView" >
  </widget>
  <widget class="myCustomTable" name="customTableView" >
  </widget>
 </widget>
 <customwidgets>
  <customwidget>
   <class>myCustomTable</class>
   <extends>QTableView</extends>
   <header>mycustomtable.h</header>
   <container>0</container>
   <pixmap></pixmap>
  </customwidget>
 </customwidgets>
</ui>

To copy to clipboard, switch view to plain text mode
