# Created by: PyQt4 UI code generator 4.11.4 # Form implementation generated from reading ui file 'TestDia.ui' Here is the code for the dialog: # -*- coding: utf-8 -*. I'm sure it's obvious to some of you what I'm doing wrong, but I'm not sure what to make of some of this code.Īlso, I am using simple test examples just to get the hang of it before making anything actually meaningful. Please bear with me, as I have very limited GUI experience, and I'm using Qt Designer to make things a little smoother for me. I've looked at answers from other places, but they don't seem to be working for me. So far, I've gotten the dialog box to appear, but pressing the button does nothing. After pressing the button to login, this dialog box should disappear, and in its place should appear the main window.

(Don't do this in real life, okay? This form is a usability and cultural-sensitivity disaster, and would be almost insultingly dumb to show in public.) We'll supply a Qt button that fills out the full name entry, shows the submit button, and prints the full name to the console.So the gist is that upon running the main window, the only thin that should pop up is a login dialog box. There is a submit button, but it is hidden. There will be a full name entry that is disabled the user cannot edit it. It will show a form that allows the user to enter a first and last name. Now, let's throw caution to the wind and look at a simple example. Example of Evaluating JavaScript in a QWebView Be careful, validate user input, and block anything that looks too clever. It would be far too simple, for example, to allow the execution of arbitrary JavaScript by naïvely building a string and sending it to evaluateJavaScript.
(It is at this point that we collectively grieve over JavaScript's ill-thought-out types.)Īn important caution about evaluateJavaScript: it has all the security implications of JavaScript's built-in eval, and should be used with the discretion that is so seldom displayed by front-end JavaScript coders. I see no better option for functions, but null is especially confusing the only way to detect a null value from evaluateJavaScript is to do the comparison val = null on the JavaScript side before you return it to Python. Note especially the behavior regarding null and functions, as both can cause code that looks right to behave wrong.
What values can be returned? The PySide documentation for QWebFrame, like that for PyQt and Qt itself, is not clear on that point. That method accepts a string of JavaScript, evaluates it in the context of the QWebView's content, and returns its value. Presenting a user with web-style content is useful in itself, but that content can be made interactive with JavaScript, which can be initiated from Python code.Ī QWebView contains a QWebFrame object, which is useful to us right now for its evaluateJavaScript method.
