        f = DialogSelectKern开发者_如何转开发elFile()

        f.show()
        app.setMainWidget(f)
        app.exec_loop()

Help me pls Thanks a Lot

Are you connecting the button click signals to handler functions?

If you are able to get one dialog to open, getting the other dialogs to open should be as simple as instantiating the new dialog and calling the .show() method in the first dialog's button handler.

Maybe you could upload your code somewhere so we can see more of it. What you have above doesn't really help much.

def displayNextForm(self):          
    self.close()
    self.extr=FormMakeImage(self,"FormMakeImage",1,Qt.WStyle_DialogBorder)
    self.extr.exec_loop()
def displayPrevForm(self):
    from DialogSelectFile import *
    self.close()
    self.ext=DialogSelectKernelFile(self,"SelectKernel",1,Qt.WStyle_DialogBorder)
    self.ext.exec_loop()

This did work smooth. I was able to implement the Next back feature. Possible warnings are occuring on Imports. but no problem on running.
Thanks all
