Java Text Formatting bold
提问by YellowSoloCup
I am having a hard time understanding how to bold the text in my GUI program. The program shows the initial value of my calculator program to be 0.0 but I need to be able to make it bold and set it to 14 font. Is there any easy way to do this?
我很难理解如何在我的 GUI 程序中加粗文本。该程序显示我的计算器程序的初始值为 0.0，但我需要能够将其设为粗体并将其设置为 14 字体。有什么简单的方法可以做到这一点吗？
JPanel x = new JPanel(new BorderLayout());
JTextField z = new JTextField();
z.setEditable(false);
z.setText("0.0");
x.add(field, BorderLayout.NORTH);

Try this:
尝试这个：
z.setFont(z.getFont().deriveFont(Font.BOLD, 14f));
deriveFont()has the advantage of being able to base your new font on the existing one. This will maintain the font characteristics that you don't mean to change.
deriveFont()具有能够基于现有字体的新字体的优势。这将保持您不想更改的字体特征。
