The g_value_get_int() function is used to retrieve the integer value stored by GValue. There are functions available for converting between all fundamental data types and GValue objects available, defined in the previous section. The next step is to store the new value of the property if it is a valid property. The property identifier is stored in prop_id, which can be compared to the installed property to find the one that is being altered. The function my_ip_address_set_address() was used to apply the changes. You can view the implementation of this function later in this section. asp.net mvc qr code generator QrCode .

QR Code is a kind of 2-D (two-dimensional) symbology developed by Denso Wave (a division of Denso Corporation at the time) and released in 1994 with the ... It would also be possible to implement the same functionality provided by this function with the method shown in the following code snippet. However, it was given to you in the expanded form, because it is a rare case when every property of a widget is the same type and is stored in an array. address[prop_id-1] = g_value_get_int (value); my_ip_address_set_address (ipaddress, address); The MyIPAddress example in this chapter is one of the simplest examples possible and could be greatly expanded. If you were implementing this widget for use in an application, you would want to provide further properties and signals, as well as provide further functionality. Keep this in mind as you continue to examine this example. The default get_property() function of the object class was overridden. Therefore, when g_object_set() is called on a property of MyIPAddress, my_ip_address_get_property() will be called as shown in Listing 11-9. Listing 11-9. Retrieving Object Properties static void my_ip_address_get_property (GObject *object, guint prop_id, GValue *value, GParamSpec *pspec) { MyIPAddress *ipaddress = MY_IP_ADDRESS (object); MyIPAddressPrivate *priv = MY_IP_ADDRESS_GET_PRIVATE (ipaddress); switch (prop_id) { case PROP_IP1: g_value_set_int (value, priv->address[0]); break; case PROP_IP2: g_value_set_int (value, priv->address[1]); break; case PROP_IP3: g_value_set_int (value, priv->address[2]); break; case PROP_IP4: g_value_set_int (value, priv->address[3]); break; default: G_OBJECT_WARN_INVALID_PROPERTY_ID (object, prop_id, pspec); break; } } We need to modify our web application to remove the .mvc extension at the beginning of the request. Place the following code in a custom HTTP module: The my_ip_address_get_property() function takes the appropriate property from the MyIPAddressPrivate structure and converts it to a GValue. The new value is then applied to the user s variable and cast to the correct variable type. The private structure is retrieved by using the MY_IP_ADDRESS_GET_PRIVATE() function that was defined at the top of the source file. Ensure that the string literal is not later used in a context in which it could be interpreted as script (such as a JavaScript eval()). Non-string literals (such as integers and floats) need to be formatted appropriately to ensure that the resulting string representation cannot result in malicious JavaScript.
