ll graphical user interfaces (UIs) are built around widgets that are arranged using layouts. In this chapter you will learn which widgets Qt provides and how they are used. You will also have a look at how layouts are used to create the desired design. The chapter alternates between using code directly and using Designer to visually build the user interface, which will teach you to understand the code that Designer generates.

${h.field( "Password", h.password(name='password'), )} ${h.field(field=h.submit(value="Sign in", name='submit'))} ${h.form_end()} AuthKit expects the username and password to be submitted as the username and password fields, respectively, and is designed to handle a POST method. AuthKit will use Python string interpolation to replace the %s string with the URL the form needs to submit to. For this to work you'll need to import password from the webhelpers.html.tags module into lib/helpers.py. Now let s create a new function in lib/auth.py to render it: def render_signin(): return render('/derived/account/signin.html') You ll need to add this import to the top of the file: from pylons.templating import render_mako as render You can then specify in the development.ini config file that, instead of using the default template, AuthKit should call the render_signin() function you created in simplesite.lib.auth to render the signin.html page. Add this to the config options: authkit.form.template.obj = simplesite.lib.auth:render_signin

As you learned in the last chapter, a dialog is a top-level window, and all dialogs are built from widgets. Further, widgets are organized using layouts that make it possible to build flexible dialogs. Layouts help make Qt special. Using layouts makes it easy to build dialogs that adapt to changes in screen resolution, font sizes, and different languages. An alternative to using layouts is static placement, which ensures that all widgets are given a size and location. So if a translator wants to use texts of different lengths in different languages, the design of the dialog must be adapted to the longest text. Using layouts, the design describes the relative placement of the widgets instead of their absolute sizes and locations. The widgets then tell layouts how much space they need and are placed in the dialog accordingly. Let s start the exploration by using Designer. Start Designer and create a new dialog from the buttons at the bottom template. Then add a group box, a line edit, a label, and a vertical spacer to the dialog, as shown in Figure 3-1. Make sure that the line edit and the label are inside the group box. You can try to move the group box. If the other widgets are inside it, they should move with the group box.

The CGI script code isn t as elegant as it could be, but it does have some benefits Let s look at the pros and cons First, here are the pros: Someone who understands HTTP and SQL will probably be able to understand most of this code because it uses standard web development techniques Coding in this manner gives the developer a huge amount of power because they have control over every aspect of the HTTP response and can write SQL queries that are as complex as they like Now, here are some of the cons: Every script in the site needs the same code to load the config file and to handle the errors Writing database access code is very repetitive, and the data structures from the database don t necessarily represent the objects your application wants to deal with.
