如何在 Progress Developer Studio 中的现有 *.w 文件上打开可视化设计器？

Question

I'm working with Progress 11.6, appBuilder and procedure editor.

I'm taking my very first steps, using Progress developer Studio (version 4.3): I'm opening a *.w file. I was expecting some kind of GUI design form, but even after having chosen the "OpenEdge AppBuilder" or the "OpenEdge Visual Designer perspective, I still only see the *.w file in text format.

What can I do in order to open the "Progress Developer Studio graphical GUI designer"? (I hope this feature exists?)

Pressing Shift+F9 does not work, and the context popup looks as follows:

Thanks in advance and sorry for this very newbie question

Hit "shift-F9" or right-click on the editor and choose "View Design"
