設置按鈕上圖標和標註的間隔, and e750 在按鈕上加上不可用圖標.
This example creates a JLabel
component with an icon.
// Fetch icon Icon icon = new ImageIcon("icon.gif"); // Create a label with text and an icon; the icon appears to the left of the text JLabel label = new JLabel("Text Label", icon, JLabel.CENTER); // Create a label with only an icon label = new JLabel(icon);
This example adds or replaces the icon in an existing JLabel
component:
// Add an icon to an existing label label.setIcon(icon);
The methods to control the position of the icon and text within a JLabel
component are identical to those of a JButton
