一个简单的解决方案可能是创建一个JLabel并将其icon属性设置为背景图片…
Icon icon = ...;JLabel background = new JLabel(icon);
将标签的布局管理器设置为
GridBagLayout…
background.setLayout(new GridBagLayout());
Set the
GridBagConstraintsinsets so that the text pane will be offset
within the contain…
GridBagConstraints gbc = new GridBagConstraints();gbc.insets = new Insets(40, 40, 40, 40);gbc.fill = GridBagConstraints.BOTH;gbc.weightx = 1;gbc.weighty = 1;
And then simply add the
JTextPaneto the label…
JTextPane textPane = ...;background.add(textPane, gbc);
You can then either add the
JLabelto the what ever container you want or
even set it as the
Jframe‘s content pane depending on your needs.
ps- You’ll need to make the text pane transparent…
For example…
