This article mainly introduces how java modifies the default font of JFrame. It is very detailed and has certain reference value. Friends who are interested must finish reading it.

Java modifies JFrame default font

The way to change the default font is simple. First of all, let's write a random button:

Import javax.swing.*; public class Test {static final int WIDTH = 300; static final int HEIGHT = 200; public static void main (String [] args) {JFrame jf = new JFrame (); jf.setVisible (true); jf.setSize (WIDTH,HEIGHT); jf.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); JPanel jp = new JPanel () Jf.setcontentPane (jp); JButton jb = new JButton ("OK"); jp.add (jb); jf.pack ();}}

Then we can add this line:

UIManager.put ("Button.font", new java.awt.Font ("Song style", 0,12))

Add the following import at the beginning:

Import javax.swing.UIManager

So you can change the font.

The font type and size can be changed freely, as long as it is installed in the computer. The "0" position represents the font style and is generally not modified. (such as italics, bold, etc., if you want to modify, please refer to API. I don't remember much either. )

It is not recommended to use personalized fonts on the Internet, because the software programs made in this way can cause font problems when used on other computers. And try to use as few obscure words as possible, lest some font libraries do not include corresponding glyphs.

Custom fonts can be encapsulated as follows: (the following section is excerpted from the network)

Public class FontClass {public static void loadIndyFont () {UIManager.put ("CheckBox.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("Tree.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("Viewport.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("ProgressBar.font", new java.awt.Font ("Song style", 0,12)) UIManager.put ("RadioButtonMenuItem.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("FormattedTextField.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("ToolBar.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("ColorChooser.font", new java.awt.Font ("Song style", 0,12)) UIManager.put ("ToggleButton.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("Panel.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("TextArea.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("Menu.font", new java.awt.Font ("Song style", 0,12)) UIManager.put ("RadioButtonMenuItem.acceleratorFont", new java.awt.Font ("Song style", 0,12); UIManager.put ("Spinner.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("Menu.acceleratorFont", new java.awt.Font ("Song style", 0,12)); UIManager.put ("CheckBoxMenuItem.acceleratorFont", new java.awt.Font ("Song style", 0,12)) UIManager.put ("TableHeader.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("TextField.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("OptionPane.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("MenuBar.font", new java.awt.Font ("Song style", 0,12)) UIManager.put ("Button.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("Label.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("PasswordField.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("InternalFrame.titleFont", new java.awt.Font ("Song style", 0,12)) UIManager.put ("OptionPane.buttonFont", new java.awt.Font ("Song style", 0,12); UIManager.put ("ScrollPane.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("MenuItem.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("ToolTip.font", new java.awt.Font ("Song style", 0,12)) UIManager.put ("List.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("OptionPane.messageFont", new java.awt.Font ("Song style", 0,12)); UIManager.put ("EditorPane.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("Table.font", new java.awt.Font ("Song style", 0,12)) UIManager.put ("TabbedPane.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("RadioButton.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("CheckBoxMenuItem.font", new java.awt.Font ("Song style", 0,12)); UIManager.put ("TextPane.font", new java.awt.Font ("Song style", 0,12)) UIManager.put ("PopupMenu.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("TitledBorder.font", new java.awt.Font ("Song style", 0,12); UIManager.put ("ComboBox.font", new java.awt.Font ("Song style", 0,12));}

Then we just need to add when we want to use it:

FontClass.loadIndyFont ()

That's all right.
