I'm trying to create a panel applet, but I'm stuck at the first step:
I've created a file.cpp with the code from the official example at
http://developer.gnome.org/panel-applet/3.0/getting-started.example.html
|#include <gtk/gtk.h>
#include <panel-applet.h>
static gboolean hello_world_applet_start (PanelApplet *applet) {
GtkWidget *label;
label = gtk_label_new ("Hello World");
gtk_container_add (GTK_CONTAINER (applet), label);
gtk_widget_show_all (GTK_WIDGET (applet));
return TRUE;
}
static gboolean hello_world_factory_callback (PanelApplet *applet, const gchar
*iid, gpointer data) {
gboolean retval = FALSE;
if (g_strcmp0 (iid, "HelloWorldApplet") == 0)
retval = hello_world_applet_start (applet);
return retval;
}
PANEL_APPLET_OUT_PROCESS_FACTORY ("HelloWorldFactory", PANEL_TYPE_APPLET,
hello_world_factory_callback, NULL)
|
compiled with
|g++ -Wall -DGTK_DISABLE_SINGLE_INCLUDES -DGDK_DISABLE_DEPRECATED
-DGTK_DISABLE_DEPRECATED -DGSEAL_ENABLE `pkg-config --cflags --libs gtk+-3.0
libpanelapplet-4.0` *.cpp -o helloworld
|
and copied under
|/usr/lib/gnome-panel/helloworld|
then I've created the file
|/usr/share/gnome-panel/4.0/applets/helloworld.panel-applet|
with this content:
|[Applet Factory]
Id=HelloWorldFactory
InProcess=true
Location=/usr/lib/gnome-panel/helloworld
Name=Hello World Applet Factory
Description=Factory for the window navigation related applets
[HelloWorldApplet]
Name=Hello World
Description=Factory for the Hello World applet example
Icon=hello-world-icon
|
all the code is taken from the documentation, but when I try to add the
applet to the panel I had this error:
|** (gnome-panel:24803): WARNING **: Failed to load applet
HelloWorldFactory::HelloWorldApplet: /usr/lib/gnome-panel/helloworld: cannot
dynamically load executable|
what's wrong??
Thanks.
