Should I make a package and use the package manager to install, test and uninstall? How do developers test apps like this? The packaging system is designed for this process. It has the added benefit of allowing you to provide a way for others to install your software. :) Using a chroot is also an easy way to do testing of your app with its environment, this can sometimes be easier than a virtual machine, but virtual machines work well too.

calling a Qt dbus method from a HILDON desktop widget
greetings;
I was creating an application with Qt that exposes a dbus service. the
service returns its output as a QStringList. I tested this dbus service
with a client written in Qt and it worked perfectly.
I wanted to create a Desktop widget that can consume this dbus service.
I created a normal C file that calls the dbus service - just as POC to
see if it works by modifying some code i found (a C file that gets the
imei , written by mr.faheem
http://talk.maemo.org/showpost.php?p=371496postcount=45)
my code is :
#include stdlib.h
#include glib.h
#include glib/gprintf.h
#include dbus/dbus-glib.h
#include string.h
#include stdio.h
static GList* ptimes_list = NULL;
int fn() {
DBusGConnection *conn;
GError *error = NULL;
conn = dbus_g_bus_get (DBUS_BUS_SYSTEM, error);
if (!conn) {
g_printerr (Error: %s\n, error-message);
g_error_free (error);
return 0;
}
DBusGProxy *proxy = NULL;
/* replaced the cinstants with values from my dbus interface */
proxy = dbus_g_proxy_new_for_name(conn, SERVICE_NAME,PATH ,INTERFACE);
if (!proxy) {
printf(No proxy, dbus_g_proxy_new_for_name() failed \n);
return 0;
}
if (!dbus_g_proxy_call(proxy,mthod_name, error,my_list) )
{
/* dbus_g_proxy_call failed */
printf(dbus_g_proxy_call(proxy,method, error,myList)
returned FALSE \n);
return 0;
}
if (!my_list) {
/* output list is empty */
printf(my_list) glist is still NULL \n);
return 0;
}
g_object_unref(proxy);
char[10] element = (char*) g_list_nth_data(my_list),0);
printf(the value of the fajr first is %s \n,element);
return 1;
}
the program fails at this point: proxy = dbus_g_proxy_new_for_name(conn,
SERVICE_NAME,PATH ,INTERFACE);
and my application stops.
I wonder what is wrong with the way I called my DBus service . Any help
is appreciated!

I think of it like this: A single source package may generate multiple programs (normally related in some way). If the programs are grouped together such that if the user installs one they almost certainly also want another then they should go into the same binary package (this often occurs with programs and scripts which make use of them or set them up, for example). On the other hand, if it is likely that the user may want one program without another, then they should go into different binary packages so that space is not wasted (and possible user confusion caused) by having both installed when you only want one. A good example of that is openssh-server and openssh-client: in many cases you need one or the other, not both, so they are two different binary packages built from the same source package (openssh).

How to override load_desktop_file in hildon home plugins?
I need to hook into load_desktop_file for my own plugin, in order
to read some custom keys there (I'm basically using a single .so file
to provide the code, and configure the functionality in desktop files).
Currently, I have a hack that seems to work, but it fails when plugin
is loaded, unloaded and loaded once more. The hack in question is:
...
G_DEFINE_DYNAMIC_TYPE_EXTENDED (ProxyHomePlugin, proxy_home_plugin,
HD_TYPE_HOME_PLUGIN_ITEM, 0,
G_IMPLEMENT_INTERFACE (HD_TYPE_PLUGIN_ITEM,
proxy_home_plugin_item_init_plugin_item));
HD_PLUGIN_MODULE_SYMBOLS_CODE (proxy_home_plugin, {}, {});
...
static void
proxy_home_plugin_item_init_plugin_item (HDPluginItemIface *iface)
{
iface-load_desktop_file = proxy_home_plugin_item_load_desktop_file;
return;
}
Note that I'm using this instead of the standard
HD_DEFINE_PLUGIN_MODULE (ExampleHomeApplet, example_home_applet,
HD_TYPE_HOME_PLUGIN_ITEM);
(As I understand it, using this wouldn't allow me to override
load_dekstop_file).
This way, my proxy_home_plugin_item_load_desktop_file() function gets
called. But indeed it
appears this is not working fine for unloading loading.
Is there another way to get at HDPluginItemIface from my
HDHomePluginItem subclass?
