List<Button> aButtons = new ArrayList<Button>();
button = new Button(buttonsComposite, SWT.PUSH);
button.setText(BTN_TEXT);
aButtons.add(button);
我有listener
makeButtonsListen(new Listener() {
@Override
public void handleEvent(Event event) {
handleButtonEvent(event);
}
});
private void makeButtonsListen(Listener listener) {
for (Button button : aButtons) {
button.addListener(SWT.Selection, listener);
}
}
我的问题是我按下按钮后event.widget == button更改的价值。怎么做onClick？我希望当点击并保持值正在改变时。目前它发生在我按下按钮之后。
