Example 1 with InputElement

use of org.gwtproject.dom.client.InputElement in project gwtproject by treblereel.

the class CheckboxCell method onBrowserEvent.

@Override
public void onBrowserEvent(Context context, Element parent, Boolean value, NativeEvent event, ValueUpdater<Boolean> valueUpdater) {
    String type = event.getType();
    boolean enterPressed = BrowserEvents.KEYDOWN.equals(type) && event.getKeyCode() == KeyCodes.KEY_ENTER;

        Boolean isChecked = input.isChecked();
        /*
       * Toggle the value if the enter key was pressed and the cell handles
       * selection or doesn't depend on selection. If the cell depends on
       * selection but doesn't handle selection, then ignore the enter key and
       * let the SelectionEventManager determine which keys will trigger a
       * change.
       */

        }
        /*
       * Save the new value. However, if the cell depends on the selection, then
       * do not save the value because we can get into an inconsistent state.
       */

            setViewData(context.getKey(), isChecked);

Example 5 with InputElement

use of org.gwtproject.dom.client.InputElement in project gwtproject by treblereel.

the class CheckBox method replaceInputElement.

/**
 * Replace the current input element with a new one. Preserves all state except for the name
 * property, for nasty reasons related to radio button grouping. (See implementation of {@link

 *
 * @param elem the new input element
