示例1: onKeyDown
import com.vaadin.client.WidgetUtil; //导入方法依赖的package包/类
@Override
public void onKeyDown(KeyDownEvent keyDownEvent) {
if (keyDownEvent.getNativeKeyCode() == KeyCodes.KEY_ESCAPE) {
SimplePanel panel = WidgetUtil.findWidget(WidgetUtil.getFocusedElement(), SimplePanel.class);
if (panel != null) {
WidgetUtil.focus(panel.getParent().getElement());
// prevent further bubbling of the event as it has only
// navigational purpose if thrown at this depth. A subsequent
// press of ESC is not stopped, so ESC abort actions of the
// application should work as soon as the focus is in
// "navigational mode" on a grid-cell
keyDownEvent.preventDefault();
keyDownEvent.stopPropagation();
}
}
}
示例2: focusInputField
import com.vaadin.client.WidgetUtil; //导入方法依赖的package包/类
private void focusInputField(Element componentElement) {
for (int i = 0; i < componentElement.getChildNodes().getLength(); i++) {
Node node = componentElement.getChildNodes().getItem(i);
if (node.getNodeName().equals("INPUT") || node.getNodeName().equals("SELECT")) {
WidgetUtil.focus((Element) node);
break;
}
}
}
示例3: focusInputField
import com.vaadin.client.WidgetUtil; //导入方法依赖的package包/类
/**
* Focus into input field below given element. Note! Element needs to be a
* table TD element so we don't mistakenly recurse too much.
*
* @param componentElement
* TD element to be searched for input and focused
* @param shiftKeyDown
* if shiftkey was down when event was triggered
*/

示例4: restoreFocus
import com.vaadin.client.WidgetUtil; //导入方法依赖的package包/类
@Override
public void restoreFocus() {

}
示例5: onKeyDown

if (isCellContainingComponent(event.getFocusedCell())) {
