Using Qt Designer file inside KDevelop project.

[Victor Röder]

  I appreciate for Harald Fernengel and Victor Roeder's reply.  I have worked out my problem finally. Indeed, "mydlg.exec()" works,(Thank you so much)  However, I'm doubt in a point.  The popup dialog window can only be active when the parent is the main interface(or frame). If I want to click a button on the popup window, and again let it pop out a small window. It doesn't work. As you said, I should declare the parent, I'm sorry that I don't know exactly how to do it. The sentense you wrote can not be simply added into the code. Could you indicate it more clearly?   

  I added the following sentence into the "baseclase.cpp"

  connect( PushButton1, SIGNAL( clicked() ), this, SLOT( Slotshow() ) );

  The popup window is displayed, but seems that it response a bit slowly. 

  Best regards,
