<title>Présentation</title>

<p><em>Properties</em> describe the configuration and state of widgets. Each
widget has its own particular set of properties. For example, a widget such as
a button has the property <code>label</code> which contains the text of the
widget. You can specify the name and value of any number of properties as
keyword arguments when creating an instance of a widget. For example, to
create a label with the text “Hello World”, an angle of 25 degrees, and
aligned to the right, you can use:</p>
<code>
label = Gtk.Label(label="Hello World", angle=25, halign=Gtk.Align.END)</code>

<p>Alternatively, you can define these properties separately by using the method associated with it.</p>
<code>
label = Gtk.Label()
label.set_label("Hello World")
label.set_angle(25)
label.set_halign(Gtk.Align.END)</code>

<p>Once you have created such a label, you can get the text of the label with <code>label.get_label()</code>, and analogously for the other properties.</p>

<p>Instead of using getters and setters you can also get and set the properties with <code>get_property(<var>"prop-name"</var>)</code> and <code>set_property(<var>"prop-name"</var>, <var>value</var>)</code>, respectively.</p>
