+--------
+
+=== Initializing the Application ===
+
+The code below shows a typical elementary application that creates a window
+entitled "Popup Tutorial" and a button which opens up popup on click. 
+<code c>
+#include <Elementary.h>
+
+EAPI_MAIN int
+elm_main(int argc, char **argv)
+{
+   Evas_Object *win, *btn;
+
+   win = elm_win_util_standard_add("Popup", "Popup Tutorial");
+   elm_policy_set(ELM_POLICY_QUIT, ELM_POLICY_QUIT_LAST_WINDOW_CLOSED);
+   elm_win_autodel_set(win, EINA_TRUE);
+   //win 400x400 px
+   evas_object_resize(win, 400, 400);
+
+   btn = elm_button_add(win);
+   elm_object_text_set(btn, "popup");
+   evas_object_resize(btn, 100, 50);
+   evas_object_move(btn, 150, 150);
+   evas_object_show(btn);
+   evas_object_smart_callback_add(btn, "clicked", _btn_click_cb, win); 
+   
+   evas_object_show(win);
+   elm_run();
+   return 0;
+}
+ELM_MAIN()
+</code>
+
+=== Creating a popup Widget ===
+
+The elm_panes widget adds a draggable bar between two contents. When dragged,
+this bar resizes the contents. To create a new Panes into an Elementary
+object, use the ''elm_panes_add()'' function:
+
+<code c>
+// Add an elm_panes
+Evas_Object *panes;
+panes = elm_panes_add(win);
+evas_object_size_hint_weight_set(panes, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
+elm_win_resize_object_add(win, panes);
+evas_object_show(panes);
+</code>
+
+=== Configure the Panes ===
+
+By default, the orientation of the Panes is vertical. To modify the
+orientation, use the ''elm_panes_horizontal_set()'' function.
+
+<code c>
+Evas_Object *panes_h;
+// Add a horizontal elm_panes
+panes_h = elm_panes_add(win);
+elm_panes_horizontal_set(panes_h, EINA_TRUE);
+</code>
+
+The code above creates another Panes object and sets the horizontal
+orientation. To add content in a panes, use the
+''elm_object_part_content_set()'' function. Here we add the horizontal Panes
+''panes_h'' to the "left" part of the first Panes ''panes'' created.
+
+<code c>
+elm_object_part_content_set(panes, "left", panes_h);
+</code>
+
+This is how to set a button object to the "right" side of our vertical Panes
+widget.
+
+<code c>
+// Create a button object
+bt = elm_button_add(win);
+elm_object_text_set(bt, "Right");
+evas_object_size_hint_weight_set(bt, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
+evas_object_size_hint_align_set(bt, EVAS_HINT_FILL, EVAS_HINT_FILL);
+evas_object_show(bt);
+
+// and set it to the "right" part of the vertical Panes
+elm_object_part_content_set(panes, "right", bt);
+</code>
+
+The content of the horizontal Panes is set with two button objects (up and
+down). When populating a vertically displayed Panes, the left content is
+placed at the top, and the right content is placed at the bottom.
+
+<code c>
+// Create a "Up" button
+bt = elm_button_add(win);
+elm_object_text_set(bt, "Up");
+evas_object_size_hint_weight_set(bt, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
+evas_object_size_hint_align_set(bt, EVAS_HINT_FILL, EVAS_HINT_FILL);
+evas_object_show(bt);
+elm_object_part_content_set(panes_h, "left", bt);
+
+// Create a "Down" button
+bt = elm_button_add(win);
+elm_object_text_set(bt, "Down");
+evas_object_size_hint_weight_set(bt, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
+evas_object_size_hint_align_set(bt, EVAS_HINT_FILL, EVAS_HINT_FILL);
+evas_object_show(bt);
+elm_object_part_content_set(panes_h, "right", bt);
+</code>
+
+The elm_panes can be dragged with the mouse but the proportion can also be set
+with the ''elm_panes_content_left_size_set()'' and
+''elm_panes_content_right_size_set()'' functions. As an example, this is how to
+set the left size of both panes to 80%.
+
+<code c>
+// Set the proportion of the panes to 80%
+elm_panes_content_left_size_set(panes, 0.8);
+elm_panes_content_left_size_set(panes_h, 0.8);
+</code>
+
+The Panes proportions can also be fixed so that the user is not able to drag
+them. To do this, use the ''elm_panes_fixed_set()'' function.
+
+<code c>
+// Fix the Panes proportion
+elm_panes_fixed_set(panes_h, EINA_TRUE);
+</code>
+
+==== Handling Signals ====
+
+The Panes widgets emit four different signals, depending on the users'
+interaction with the draggable bar.
+
+    * "press" - The pane is pressed.
+    * "unpressed" - The pane is released after being pressed.
+    * "clicked" - The pane is clicked.
+    * "clicked,double" - The pane is double clicked.
+
+A callback function is added for each of them.
+
+//**__"click" Signal__**//
+
+The callback function for the clicked signal prints "Clicked" to standard
+output.
+
+<code c>
+// click callback
+static void
+_clicked_cb(void *data, Evas_Object *obj, void *event_info)
+{
+   printf("Clicked\n");
+}
+</code>
+
+This is how to register this callback function to the vertical panes.
+<code c>
+    evas_object_smart_callback_add(panes, "clicked", _clicked_cb, panes);
+</code>
+
+//**__"press" Signal__**//
+
+The callback function for the clicked signal prints "Clicked" to standard
+output.
+
+<code c>
+// press callback
+static void
+_press_cb(void *data, Evas_Object *obj, void *event_info)
+{
+   printf("Pressed\n");
+}
+</code>
+
+The callback function for the "press" signal prints "Pressed" to the standard
+output.
+
+<code c>
+evas_object_smart_callback_add(panes, "press", _press_cb, panes);
+</code>
+
+//**__"unpress" Signal__**//
+
+For the "unpress" signal, the proportion size of the left content of the Panes
+widget is printed to the standard output. To do this, use the
+''elm_panes_content_left_size_get()'' function.
+
+<code c>
+static void
+_unpress_cb(void *data, Evas_Object *obj, void *event_info)
+{
+   printf("Unpressed, size : %f\n", elm_panes_content_left_size_get(obj));
+}
+</code>
+
+This is how to register this callback function to the vertical panes.
+<code c>
+evas_object_smart_callback_add(panes, "unpress", _unpress_cb, panes);
+</code>
+
+//**__"clicked,double" Signal__**//
+
+Hide the left part of the Panes widget on the "clicked,double" signal and set
+the left proportion to 0.0. To restore the left part proportion with a double
+click on the hidden part of the Panes widget, use the
+''elm_panes_content_left_size_get()'' and
+''elm_panes_content_left_size_set()'' functions, and a variable to store the
+value of the current proportion.
+
+<code c>
+// double clicked callback
+static void
+_clicked_double_cb(void *data, Evas_Object *obj, void *event_info)
+{
+   static double size = 0.0;
+   double tmp_size = 0.0;
+   tmp_size = elm_panes_content_left_size_get(obj);
+   if (tmp_size > 0)
+     {
+        elm_panes_content_left_size_set(obj, 0.0);
+        printf("Double clicked, hidden.\n");
+     }
+   else
+     {
+        elm_panes_content_left_size_set(obj, size);
+        printf("Double clicked, restoring size.\n");
+     }
+   size = tmp_size;
+}
+</code>
+
+This is how to register this callback function to the Panes.
+
+<code c>
+evas_object_smart_callback_add(panes, "clicked,double", _clicked_double_cb, 
panes);
+</code>
