<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Marrying the GUI components to processes that come fairly easy to me on the cli is a struggle for me at this point. I have a mainwindow and some dialogs, all of which I can open ok and do some processing, etc. What’s difficult for me
is figuring out where to draw the lines between application function and GUI control processing. For example, I have a main window and one dialog that connects to a device for authentication. The dialog has the lineedit widgets for collecting the username,
password, and host and was designed with Designer. Currently, my code looks like this:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">class Main(QMainWindow, Ui_mw_Editor):<o:p></o:p></p>
<p class="MsoNormal"> def __init__(self):<o:p></o:p></p>
<p class="MsoNormal"> QMainWindow.__init__(self)<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal"> # This is always the same<o:p></o:p></p>
<p class="MsoNormal"> self.setupUi(self)<o:p></o:p></p>
<p class="MsoNormal"> # QActions on Editor Menubar / Toolbar<o:p></o:p></p>
<p class="MsoNormal"> self.actionConnect.triggered.connect(self.connectDialog)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> def connectDialog(self):<o:p></o:p></p>
<p class="MsoNormal"> self.connectdlg = ConnectDlg()<o:p></o:p></p>
<p class="MsoNormal"> self.connectdlg.show()<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">class ConnectDlg(QDialog, Ui_dia_connect):<o:p></o:p></p>
<p class="MsoNormal"> def __init__(self):<o:p></o:p></p>
<p class="MsoNormal"> QDialog.__init__(self)<o:p></o:p></p>
<p class="MsoNormal"> self.setupUi(self)<o:p></o:p></p>
<p class="MsoNormal"> self.pb_ok.clicked.connect(self.button_click)<o:p></o:p></p>
<p class="MsoNormal"> self.pb_cancel.clicked.connect(self.reject)<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal"> def button_click(self):<o:p></o:p></p>
<p class="MsoNormal"> self.host = self.cb_hostname.currentText()<o:p></o:p></p>
<p class="MsoNormal"> self.uname = self.le_username.text()<o:p></o:p></p>
<p class="MsoNormal"> self.upass = self.le_password.text()<o:p></o:p></p>
<p class="MsoNormal"> #print "Host is %s, Username is %s, Password is %s." % (self.host, self.uname, self.upass)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">That works. Now to the questions on approach:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">1.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Should I move each dialog’s code into a separate file and import it to keep the main window code clean?<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">2.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>I’m still unsure how to pass data back from a dialog to the main window. If I set the call to the dialog in the main class to a variable, would any object I return from the dialog be an attribute of that object, or would I need to
create n objects for each object being returned?<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">3.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Does the return command destroy the dialog, or do I need to have a self.accept before the return? The dialog closes, but I’m not sure what’s proper to ensure cleanup in the backend.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Basically, just reaching out to the pros for some simple guidance on approach. Thanks,<o:p></o:p></p>
