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.

I am working on a GUI application under KDE3/Qt environment for a few weeks. However, I'm still a beginer. In my applicaiton, a simple function doesn't work. :( I want to click a button, then popup a dialog window. I've built the dialog window file using Qt designer, and integrated it into KDE Project. In the slot by connecting the "click button" signal, I wrote code:
createdlg is the baseclass name of the dialog. But it didn't be actived when I launch the application. Anyone can kindly give me a clue or advice? Thanks heaps!
