将组件插入JTextPane组件的Java程序


Java program to insert a component into a JTextPane component

假设以下是我们的JTextPane-

1
2
3
JTextPane textPane = new JTextPane();
textPane.setForeground(Color.white);
textPane.setBackground(Color.blue);

现在，设置样式和属性。 另外，设置字体-

1
2
3
4
5
6
SimpleAttributeSet attributeSet = new SimpleAttributeSet();
StyleConstants.setItalic(attributeSet, true);
textPane.setCharacterAttributes(attributeSet, true);
textPane.setText("Press the Button");
Font font = new Font("Verdana", Font.BOLD, 22);
textPane.setFont(font);

在上面显示的文本之后，我们将使用setComponent()插入一个组件-

1
2
3
4
StyledDocument doc = (StyledDocument) textPane.getDocument();
Style style = doc.addStyle("StyleName", null);
StyleConstants.setComponent(style, new JButton("Submit"));
doc.insertString(doc.getLength(),"invisible text", style);

以下是将组件插入组件的示例。 在这里，我们在JTextPane中设置了一个按钮组件-
