問題描述

我正在使用 Kivy 開發應用程序.我正在使用 Kivy ActionBar 為我的應用程序創建一個菜單欄.

I am working on developing an application using Kivy. I am using Kivy ActionBar for creating a menu bar for my application.

請參考附圖

我想刪除 Kivy 圖標并將其他選項(文件/編輯)移動到左側.請找到我的代碼片段.

I want to remove the Kivy icon and move the other options(file / edit) to the left. Please find the snippet of my code.

menuAcBar  = ActionBar(pos_hint={'top': 1.3})
menuAcView = ActionView()
menuAcBar.add_widget(menuAcView)
menuAcPrevious = ActionPrevious(with_previous=False)

menuAcView.add_widget(menuAcPrevious)
menuAcView.add_widget(ActionButton(text="File"))
menuAcView.add_widget(ActionButton(text="Edit"))
menuAcView.add_widget(ActionButton(text="Documents"))
menuAcView.add_widget(ActionButton(text="help"))

self.add_widget(menuAcBar)

推薦答案

在ActionPrevious上可以設置app_icon.docs 中略低一些.您可以為圖標的大小設置 app_icon_width/height，甚至可以使用 app_icon='' 將其刪除，但它會留下白色矩形而不是透明".保留 app_icon 并僅設置寬度和高度使其不可見.

Right on ActionPrevious you can set app_icon. It's a little bit lower in docs. You can set app_icon_width/height for size of the icon or even remove it with app_icon='', but it'll leave white rectangle instead of a "transparent". Leave app_icon be and set only width and height to make it invisible.

?ctionPrevious 具有 ActionItem 的 minimum_width 屬性，因此您需要像這樣更改它:

The ?ctionPrevious has ActionItem's minimum_width property, therefore you need to change it like this:

menuAcPrevious = ActionPrevious(with_previous=False,
                         app_icon=<your_image>,
                         app_icon_width=1,
                         app_icon_height=0,
                         minimum_width=10,
                         size_hint_x: None)

似乎 ActionPrevious 留下了額外的未使用空間，即使 title='' 和 minimum_width=1 并且您無法通過孩子訪問該死的東西因為它是 未注冊，所以我唯一的想出的是調整它的大小，這樣你就不會再看到它了:

It seems that ActionPrevious leaves additional unused space even if title='' and minimum_width=1 and you can't access the damn thing through children because it's unregistered, therefore the only thing I came up with is resizing it so you won't see it anymore:

ActionPrevious(
    size_hint_x = None,
    width = 0,
    app_icon_width = 0.1,
    with_previous = False)
