Problem with align GUI components.

Hi to all, I am trying to put a label aligned to the top and a button in the middle, I have this code: (My target is mobile 2.4)

    ad->label = elm_label_add(ad->conform);
    elm_object_text_set(ad->label, "<align=center>Waiting GPS status</align>");
    evas_object_size_hint_weight_set(ad->label, 0.5, 0.5);
    evas_object_size_hint_align_set(ad->label, 0.0, 0.0);
    elm_object_content_set(ad->conform, ad->label);
    ad->btn = elm_button_add(ad->conform);
    elm_object_text_set(ad->btn, "Button");
    evas_object_smart_callback_add(ad->btn, "clicked", btn_clicked_cb, ad);
    evas_object_size_hint_weight_set(ad->btn, 0.3, 0.3);
    evas_object_size_hint_align_set(ad->btn, 0.5, 0.5);
    elm_object_content_set(ad->conform, ad->btn);

  
    evas_object_show(ad->win);

Well, you can see only one super huge button in the screen covering everything.

I couldnt find any compilable example for API 2.4 in the ducumentation for play with values and underestand how is working.

Please, cuuld anyone help me? Thanks!

Actually this also not make any change...

ad->label = elm_label_add(ad->conform);
    elm_object_text_set(ad->label, "<align=center>Waiting GPS status</align>");
    evas_object_move(ad->label, 0, 50);
    evas_object_resize(ad->label, 600, 80);
    elm_object_content_set(ad->conform, ad->label);

    /* Button */
    ad->btn = elm_button_add(ad->conform);
    elm_object_text_set(ad->btn, "Button");
    evas_object_smart_callback_add(ad->btn, "clicked", btn_clicked_cb, ad);
    evas_object_move(ad->btn, 0, 200);
    evas_object_resize(ad->btn, 300, 80);
    elm_object_content_set(ad->conform, ad->btn);

    /* Show window after base gui is set up */
    evas_object_show(ad->win);

The button still covering everything!

Hi Carlos

i always use box container to display widgets on the screen. I can control widgets in box container easily.

The following  function is used to add widget in box and use that function for every widget.

static void pack(Evas_Object *b, Evas_Object *c, double h_weight,double v_weight,double h_align,double v_align)
{

	Evas_Object *frame = elm_frame_add(b);
	elm_object_style_set(frame,"pad_small");
	evas_object_size_hint_weight_set(frame,h_weight,v_weight);	
	evas_object_size_hint_align_set(frame,h_align,v_align);	
	evas_object_size_hint_weight_set(c,EVAS_HINT_EXPAND,EVAS_HINT_EXPAND);
	evas_object_size_hint_align_set(c,EVAS_HINT_FILL,EVAS_HINT_FILL);	
	evas_object_show(c);	
	elm_object_content_set(frame,c);
	elm_box_pack_end(b,frame);
	evas_object_show(frame);	
	elm_box_pack_end(b,frame);

}

Here

h_weight value range: 0-1
v_weight value range: 0-1
h_align value : 0.0 = left. 0.5 = center. 1.0 = right. -1 = full
v_align value : 0.0 = top. 0.5 = middle. 1.0 = bottom. -1 = full

If elm_frame_add() shows error , goto project header file --> efl_extension.h --> elm_frame.h, then remove the comment of following line
EAPI Evas_Object   *elm_frame_add(Evas_Object *parent) ;

Now from create_base_gui() function call  the above function after creating a widget.

 ad->label = elm_label_add(ad->conform);
 elm_object_text_set(ad->label, "<align=center>Waiting GPS status</align>");
 pack(box,ad->label,0.0,0.0,0.0,0.0);

 ad->btn = elm_button_add(ad->conform);
 elm_object_text_set(ad->btn, "Button");
 evas_object_smart_callback_add(ad->btn, "clicked", btn_clicked_cb, ad);	 
 pack(box,ad->btn,0.0,1.0,-1.0,0.0);

Thanks a lot. But

elm_frame_add

Is not defined, at las in Elementary.h of TizenSDK 2.4, I guess is deprecated because is commented. However, is solver, you are right, using box is the solution (without frame...). I finnish the first funtional code of a GPS tracker who can write GPX files, maybe you wanna have a look and make any suggestion or contribution, is GPL.

Thanks a lot
