我遇到了问题!我想有两个显示不同图片的按钮。当我选择第一个单选按钮时,我的图片会出现,但是当我选择第二个单选按钮后,我的第二张图片将不会出现?
这是我的代码:
final Button buttondog= new Button(c1, SWT.RADIO);
buttondog.setText("dog");
buttondog.setBounds(10, 20, 169, 21);
final Button buttoncat= new Button(c1, SWT.RADIO);
buttoncat.setText("cat");
buttoncat.setBounds(10, 50, 169, 21);
buttonradio.addListener (SWT.Selection, new Listener () {
public void handleEvent (Event event) {
buttoncat.setSelection(false);
buttondog.getSelection == true;
img = new Label(page1, SWT.TOP);
img.setBounds(300, 100, 992, 568);
img.setImage(SWTResourceManager.getImage("dog.jpg"));
img.setVisible(true);
}
});
buttoncat.addListener (SWT.Selection, new Listener () {
public void handleEvent (Event event2) {
buttondog.setSelection(false);
buttoncat.setSelection(true);
img2 = new Label(page1, SWT.TOP);
img2.setBounds(300, 100, 992, 568);
img2.setImage(SWTResourceManager.getImage("cat.jpg"));
img2.setVisible(true);
}
});
