問題描述

BoxLayout(orientation='vertical') 與 GridLayout(cols=1):

他們都做同樣的事情，不是嗎?有理由選擇其中一個嗎?

They both do the same thing, no? Is there a reason to choose one over the other?

推薦答案

區別在于大小和位置.

一般來說，GridLayout (cols: 1) 總是將元素保持在一列中，而有使用 BoxLayout (orientation: 'vertical') 時更靈活地組織單個小部件.

In general, GridLayout (cols: 1) is always going to keep the elements in one column, whereas there is more flexibility to organize individual widgets when you use BoxLayout (orientation: 'vertical').

這是一個非常簡單的示例，說明您可以使用 BoxLayout 進行操作，因為它支持 pos_hint、size 和 size_hint(以及其他，例如 center_x、x、y、right，-注意它們也依賴于BoxLayout 的 vertical 或 horizo??ntal 方向會影響各個小部件:

Here is a very simple example of something you can do with BoxLayout because it honours pos_hint, size and size_hint (and others such as center_x, x, y, right, - notice that they also depend on the vertical or horizontal orientation of the BoxLayout) which affects individual widgets:

<Test@BoxLayout>:
    orientation: 'vertical'
    Button:
        text: 'a'
        size_hint: None, None
        size: 100,50
        pos_hint: { 'center_x' : .5 }
    Button:
        text: 'b'

這是 200x200 屏幕中的輸出:

This is the output in a 200x200 screen:

如果您嘗試做同樣的事情，但改用 GridLayout，那么您會得到:

If you attempt to do the same but using GridLayout instead, then you get this:

最后，GridLayout 有一些屬性來控制列的大小:

Finally, GridLayout has some properties to control the size of the column:

• col_default_width:為所有列的默認寬度
• col_width:每列的寬度列表(在此沒有用處案例，因為我們只有一個)
• col_force_default:它將忽略單個小部件的任何現有 size_hint 或 size 并強制列寬
• minimum_width:所以列不會縮小太多

• col_default_width: for the default width of all the columns
• col_width: a list of widths for each column (not useful in this case since we have just one)
• col_force_default: which will ignore any existing size_hint or size for individual widgets and force the column width
• minimum_width: so the column not shrink too much
