java - 文本将提供的像素

Question

是否有可能根据其字体获取字符串的宽度？

例如，如果字体大小是 40，字符串是“hi”，你可以做 2*40。

这方面的一个例子是

startX = 260; startWidth = "Start".length()*getFont().getSize();
startY = getHeight()-startWidth-20; 
startHeight = getFont().getSize();

Answer 1

It really depends on the type of font, whether it's monospaced or proportional. Most font now are proportional so you would not simply be able to calculate num_of_chars * n.

The gui interface you are using should give you the width of the container once it has been populated with the given text.
