添加到标签时，x像素后的新行(tkinter) [英] New line after x pixels when adding to a label (tkinter)

问题描述

当前，当我写标签时，它只会写一行，有时会消失在标签的边缘，就像这样:

Currently when I write to a label, it will write only one line, and this sometimes disappears off the edge of the label, like so:

这是我用来写标签的代码示例:

Here is an example of the code I am using to write to the label:

def updateLabel(self, event):
    global string
    global labelContents
    global windowCommand
    global currentEnvironment
    if event != "no input":
        windowCommand = self.getEntry(event)
        labelDisplay = "> " + windowCommand
        labelContents += labelDisplay
        labelContents += "\n"
        self.checkLabel()
        string.set(labelContents)
        self.textEntry.delete(0, END)
        self.master.after(0, play)
    else:
        self.checkLabel()
        string.set(labelContents)

labelContents += "You have died. Game over." + "\n"
labelContents += "You scored {0}.".format(score) + "\n"
app.updateLabel("no input")

我想知道是否有某种方法可以在经过一定数量的像素(标签宽度)后将其强制到新行，而不必遍历并在所有位置添加"\ n"(因为最后一行是1约有150种可能性).

I would like to know if there was any way to force it to a new line after a certain amount of pixels (the label width) without having to go through and add "\n" everywhere (as that last line is 1 of ~150 possibilities).

推荐答案

标签小部件为此提供了一个完美的选择:wraplengt.

Label widget has a perfect option for that: wraplengt.

label = Label(parent, text="This is a really long text; " * 5, wraplengt=200)

从关于effbot.org的标签文档:

确定何时将标签的文本换成多行.这以屏幕单位给出.默认值为0(不环绕).

Determines when a label’s text should be wrapped into multiple lines. This is given in screen units. Default is 0 (no wrapping).
