常用Swing知識(shí)點(diǎn)、技巧總結(jié)，逐步積累添加中
1、如何給JPanel，JFrame，JDialog設(shè)置背景
下載鏈接
2、如何去掉JTextField中輸入文本框時(shí)的跟隨方框
System.setProperty("java.awt.im.style", "on-the-spot");
3、表格間隔色
JTable table = new JTable() {
public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
Component prepareRenderer = super.prepareRenderer(renderer, row, column);
if (row % 2 == 0) {
prepareRenderer.setBackground(Color.LIGHT_GRAY);
} else {
prepareRenderer.setBackground(Color.WHITE);
}
return prepareRenderer;
}
};
4、仿MSN彈出面板
下載鏈接
5、Spinner循環(huán)
原理:重載了getNextValue和getPreviousValue兩個(gè)方法
final SpinnerNumberModel model = new SpinnerNumberModel();
model.setMaximum(new Integer(5));
model.setMinimum(new Integer(0));
final JSpinner spinner = new JSpinner() {
public Object getNextValue() {
if (this.getValue().toString().equals(model.getMaximum().toString())) {
return model.getMinimum();
}
return super.getNextValue();
}
public Object getPreviousValue() {
if (this.getValue().toString().equals(model.getMinimum().toString())) {
return model.getMaximum();
}
return super.getPreviousValue();
}
};
spinner.setModel(model);
6、2D去鋸齒
只是因?yàn)槊Q太長(zhǎng)...
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING , RenderingHints.VALUE_ANTIALIAS_ON);
7、修改全局文字
public static void setUIFont (javax.swing.plaf.FontUIResource f){
java.util.Enumeration keys = UIManager.getDefaults().keys();
while (keys.hasMoreElements()) {
Object key = keys.nextElement();
Object value = UIManager.get (key);
if (value instanceof javax.swing.plaf.FontUIResource)
UIManager.put (key, f);
}
}
最后修改:10.06.24
