如何在垂直制表符中水平放置文本? [英] How to position text horizontally in vertical tabs?

问题描述

我有垂直标签，但想旋转"标签标签，以便水平阅读.该怎么办?

I have vertical tabs but want to 'rotate' the tab labels so that these read horizontally. How could this be done?

kivy文件包含:

TabbedPanel:
    id: tab_panel
    tab_pos: 'left_top'
    do_default_tab: False

    TabbedPanelItem:
        text: '1'

    TabbedPanelItem:
        text: '2'

    TabbedPanelItem:
        text: '3'

推荐答案

编辑:实际上， IS 是可能的！

Actually, it IS possible!

TabbedPanelItem:
    text: '2'
    canvas.before:
        PushMatrix
        Rotate:
            angle: -90
            axis: 0,0,1
            origin: self.center
    canvas.after:
        PopMatrix

使用当前的api是不可能的.如果您设法做到这一点，将非常丑陋，因为它会拉伸制表符并将其设置为 square 或什至另一个90°旋转的矩形，它将尽可能地拧您的Layout-原始选项卡看起来像随意的Button和整个TabbedPanel，作为初学者尝试制作html页面的尝试想要限制自己使用当前字体大小的3-4个字符.只是说.

With current api impossible. And it'll be really ugly if you manage to do it, because it'll stretch the tab-header and make it a square or even another, 90° rotated rectangle, which will screw your Layout as much as possible - the original tab will look like a casual Button and whole TabbedPanel as a beginner's try to make html page if you don't want to limit yourself to 3-4 characters with current font size. Just saying.

您可能会尝试编辑源代码，而直接执行源代码的方法之一就是制作一个自定义的ToggleButton，TabbedPanelHeader会继承该自定义ToggleButton并使用Push/PopMatrix()对其进行旋转.

You may try to edit the source and one of the ways how to do it directly is making a custom ToggleButton from which TabbedPanelHeader inherits and rotate it with Push/PopMatrix().

另一种(也是更合理的)方法是使选项卡看起来像这样:

The other (and more reasonable) way would be to make tabs look like this:

t|
a| content
b|
_|

即文字向上->向下，尽管除了旋转整个内容并使用这样的字符外，我不知道该怎么做:t\na\nb

i.e. text going up -> down, though I don't know how to do it except rotating the whole thing and work with characters like this: t\na\nb
