Java中带有对齐文本的多行标签/区域/窗格 [英] Multi line label/area/pane in Java with Justified text

问题描述

我有一个有趣的任务.考虑一个长度未知的String content.我想将content和Font font一起显示为已确定文本.我需要知道如果指定width，这将占用什么height.我想在屏幕中间显示此文本，但其宽度必须为width.

I have an interesting task. Consider a String contentwith unknown length. I'd like to display content with a Font font with Justified text. I need to know what height this would take up if I specify the width. I want to display this text in the middle of the screen but it must have a width of width.

因此，我想做如下事情.

Hence, I would like to do something such as the following.

//create a JTextPane or JTextArea
pane.setText(content);
pane.setFont(font);
//set the width of the pane here
//get the height of the full text block if its justified
pane.setLocation(screenWidth/2 - width/2, screenHeight/2, height/2);

我该怎么做?

推荐答案

通常，对齐方式是相反的.

Normally, justification is done the other way around.

文本具有固定的高度，您可以通过以下方式之一调整文本的宽度:

The text has a fixed height, and you adjust the width of the text in one of the following ways:

• 在单词之间添加空格.更简单，但外观上不那么吸引人.
• 在字母之间添加空格.这称为字距.

如果您调整高度以使宽度正确，则文本中的每一行都将具有不同的高度.

If you adjust the height so that the width is correct, every line in your text will have a different height.
