[Qt-interest] custom widgets in designer

[Alex Custov]

Hi.

In Qt3 it was possible to add custom widgets in designer, simply
adding header file to the project. Then I was able to place this
custom widget on the form.

I didn't find this possibility in Qt4 designer. However recently I got
some project and found in its .ui file the following code:

 <customwidgets>
  <customwidget>
   <class>MComboBox</class>
   <extends>QComboBox</extends>
   <header>MComboBox.h</header>
  </customwidget>
 </customwidgets>

"uic" generates well-formed .h file from it, including MComboBox.h as
it described in .ui file.

Does it mean that it is still possible to add custom widgets? How can
I do it? Thanks.

P.S. This project doesn't use plugins for designer.
