Tizen 4:为什么一个盒子容器不能容纳另一个布局? [英] Tizen 4: Why is a box container not able to hold another layout?

问题描述

我在 Tizen 4.0 上创建了一个盒子容器:

I create a box container on Tizen 4.0:

Evas_Object* box = elm_box_add(naviframe);
evas_object_size_hint_weight_set(box, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
evas_object_size_hint_align_set(box, EVAS_HINT_FILL, EVAS_HINT_FILL);
evas_object_show(box);
elm_object_content_set(naviframe, box);

然后我想将edje的布局添加到框中:

Then I want to add a layout from edje into the box:

Evas_Object* page = elm_layout_add(box);
elm_layout_file_set(page, "layout.edj", "groupname_in_layout");
evas_object_show(page);
elm_box_pack_end(box, page); 

然后我把盒子推到屏幕上:

Then I push the box into the screen:

elm_naviframe_item_push(naviframe, NULL, NULL, NULL, box, "empty");

但布局未显示在模拟器上.

但是，如果我只是将布局添加到导航框(而不是框)，它会显示:

However, if I just simply add the layout to the naviframe (and not to the box), it's displayed:

//elm_box_pack_end(box, page); 
elm_naviframe_item_push(naviframe, NULL, NULL, NULL, page, "empty");

如果我以编程方式创建标签并将其放入框中，也会显示:

Evas_Object* text = elm_label_add(box);
elm_object_text_set(text, "<align=center>Hello Tizen</align>");
evas_object_show(text);
elm_box_pack_end(box, text);

elm_naviframe_item_push(naviframe, NULL, NULL, NULL, box, "empty");

为什么在地球上拒绝 Box 布局包含 Tizen 中唯一合理的布局(Layout)??尤其是在阅读了他们的文档"之后:

Why on Earth denies a Box layout to contain the only reasonable layout in Tizen (Layout)?? Especially after reading their "docs":

您可以将任何 Evas 对象添加到框中.

You can add any Evas object to the box.

根据我的知识，任何"表示任何:因此 Layout 也是名为any"的组的一部分.

Based on my knowledge, "any" means any: so a Layout is also part of the group named "any".

推荐答案

实际上 box can 只需要设置布局的对齐和粗细，无论布局定义包含什么.

Actually box can contain just you have to set the align and weight of the layout, no matter what the layout definition contains.

这里有很大帮助:如何在原生 Tizen 应用程序?，谢谢@IsaacCisneros.

Great help from here: How to add edit text in native Tizen app?, thanks @IsaacCisneros.

所以我只有添加

evas_object_size_hint_align_set(page, EVAS_HINT_FILL, 0.0);
evas_object_size_hint_weight_set(page, EVAS_HINT_EXPAND, 0.0);

现在它可以工作了.
