FontMetrics对象并入setfont？ [英] FontMetrics setFont?

问题描述

我想提出一个程序中，我需要设置字体一个FontMetrics对象中。我已经创建的FontMetrics，但现在我没有访问Graphics对象了。然而，我想改变的FontMetrics里面的字体，也就是创建一个新的FontMetrics，用新字体，但使用相同的图形上下文。我可以做图形avaliable，但它会占用大量的时间，这将没有任何意义可言这样做。会有人知道它更简单的方法？它作用似乎因此obvius它应该是一个办法，也许我只是失去了一些东西真的很愚蠢的（我看了看文档，没有发现任何）。请帮助！

I am making a program in which I need to set the Font inside a FontMetrics object. I have already created the fontmetrics before, but now I don't have access to the Graphics object anymore. Yet, I want to change the font inside the FontMetrics, that is, create a new FontMetrics, with a new Font, but using the same Graphic context. I could make the Graphics avaliable, but it would take a lot of time and it wouldn't make sense at all to do so. Would anyone know an easier way to it? It seens so obvius it should be a way, maybe I am just missing something really stupid (I looked at the documentation and found nothing). Please help!

推荐答案

也许最简单的方法是使用<一个href=\"http://docs.oracle.com/javase/7/docs/api/javax/swing/JComponent.html#getFontMetrics%28java.awt.Font%29\"相对=nofollow> JComponent.getFontMetrics（字体） 。这种方法尊重的电流的JComponent 的FontRenderContext （注意： Component.getFontMetrics 将的不的尊重电流的FontRenderContext ）。

Probably the easiest way would be to use JComponent.getFontMetrics(Font). This method respects the JComponent's current FontRenderContext (Note:Component.getFontMetrics will not respect the current FontRenderContext).
