問題將小部件添加到水平箱式容器

Question

即時嘗試在本機tizen中製作窗體屏幕。

This is what i want, but every time i try to make a box with horizontal orientation with 2 widgets (the label, and the text input) it doesnt appear when i execute my code.

我尋找這樣用方框的例子，但我無法找到他們。如果有人能夠幫助那會很好。

感謝。

這是我的代碼

static void 
    create_base_gui(appdata_s *ad) 
    { 

// Create the window 
ad->win = elm_win_util_standard_add(PACKAGE, PACKAGE); 
elm_win_conformant_set(ad->win, EINA_TRUE); 

// Advertise which rotations are supported by the application; the 
// device_orientation callback is used to do the actual rotation when 
// the system detects the device's orientation has changed 
if (elm_win_wm_rotation_supported_get(ad->win)) { 
    int rots[4] = { 0, 90, 180, 270 }; 
    elm_win_wm_rotation_available_rotations_set(ad->win, (const int *)(&rots), 4); 
} 

// Add a callback on the "delete,request" event; it is emitted when 
// the system closes the window 
evas_object_smart_callback_add(ad->win, "delete,request", win_delete_request_cb, NULL); 

// Alternatively, elm_win_autodel_set() can be used to close 
// the window (not the application) automatically 
// with the Back button, for example 
// elm_win_autodel_set(ad->win, EINA_TRUE); 

// Create the conformant 
ad->conform = elm_conformant_add(ad->win); 

// Set the conformant use as much horizontal and vertical space as 
// possible, that is, expand in both directions 
evas_object_size_hint_weight_set(ad->conform, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND); 

// Set the conformant as the resize object for the window: 
// the window and the conformant grow together 
// in proportion to each other 
elm_win_resize_object_add(ad->win, ad->conform); 


// Create the naviframe 
ad->naviframe = elm_naviframe_add(ad->conform); 
elm_object_content_set(ad->conform, ad->naviframe); 

// Show the box 
evas_object_show(ad->conform); 

// Show the conformant since all widgets are hidden by default 
evas_object_show(ad->conform); 

// Create the box 
Evas_Object *box = elm_box_add(ad->naviframe); 

// Set the box vertical 
elm_box_horizontal_set(box, EINA_FALSE); 

// The box expands when its contents need more space 
evas_object_size_hint_weight_set(box, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND); 

// The box fills the available space 
evas_object_size_hint_align_set(box, EVAS_HINT_FILL, EVAS_HINT_FILL); 

// Add the box in the naviframe container 
elm_naviframe_item_push(ad->naviframe, "Hello World", NULL, NULL, box, NULL); 

// Show the box 
evas_object_show(box); 

Evas_Object *box_one = elm_box_add(box); 
elm_box_horizontal_set(box_one, EINA_TRUE); 
evas_object_size_hint_weight_set(box_one, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND); 


// Create the label 
Evas_Object *label = elm_label_add(box_one); 
// The label expands when its contents need more space 
evas_object_size_hint_weight_set(label, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND); 
// The box fills the available space on the horizontal axis and is 
// centered on the vertical axis (placed at 0.5 vertically, that is, in the 
// middle) 
evas_object_size_hint_align_set(label, 0.5, EVAS_HINT_FILL); 

// Set the text for the label and set formatting through the HTML tags: 
// - "Hello World!" centered on the first line 
// - skip a line 
// - Add a longer text that does not fit on a single line but wraps at 
// the word boundaries 
elm_object_text_set(label, 
     "<align=center>Hello World!</align><br>" 
     "<br>" 
     "<wrap = word>Clicking on the button below closes the application.</wrap>"); 

// Add the label at the end of the box 
elm_box_pack_end(box_one, label); 

// Show the label 
evas_object_show(label); 

// Create the button 
Evas_Object *button = elm_button_add(box_one); 

// The box expands when its contents need more space 
evas_object_size_hint_weight_set(button, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND); 

// The button fills the available space on the horizontal axis and is 
// placed at the bottom of the vertical axis (1 is the end of the axis, 
// the coordinates start at (0, 0) on the top-left corner 
evas_object_size_hint_align_set(button, 0.5, EVAS_HINT_FILL); 

// Set the text for the button 
elm_object_text_set(button, "Close!"); 

// Add a callback on the button for the "clicked" event; implementation of 
// the callback is below 
//evas_object_smart_callback_add(button, "clicked", clicked_cb, NULL); 

// Add the widget at the end of the box; since the axis starts in the top left 
// corner and the box is vertical, the end of the box is below the label 
//elm_box_pack_end(box_one, button); 

// Show the button 
evas_object_show(button); 

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

} 

Answer 1

的問題是：

1. 您沒有在 「box_one」 的末尾添加按鈕。在你給定的代碼中你註釋了elm_box_pack_end（box_one，button）這一行。

2. 您沒有顯示「box_one」。您需要使用evas_object_show（box_one）顯示「box_one」容器
