Client Scripting Focus issue

[davidleetw]

Dear all,

A Text with style SWT.ICON_CANCEL，the Text widget lost focus after clicking the ERASER icon in it
, we must click the Text again to get focus for new input!
How to make the Text widget still get the focus after cleaning the existed content?
Thank you!

E.js

It seems that there is currently no server side option to achieve that, but you can do it on the client side:

final Text text = new Text(shell, SWT.ICON_CANCEL | SWT.ICON_SEARCH | SWT.SEARCH);
final JavaScriptExecutor javaScriptExecutor = RWT.getClient().getService(JavaScriptExecutor.class);
if (javaScriptExecutor != null) {
	final String code = "rap.getObject('" + WidgetUtil.getId(text) + "').$input.focus();";
	text.addSelectionListener(new SelectionAdapter() {
		@Override
		public void widgetDefaultSelected(SelectionEvent e) {
			if (e.detail == SWT.ICON_CANCEL || e.detail == SWT.ICON_SEARCH) {
				javaScriptExecutor.execute(code);
			}
		}
	});
}

RAP team: If this behavior should be standard, it could be achieved by forcing the focus to the text field in rwt.widgets.Text.js:

_onMouseDownUp : function( event ) {
  this.base( arguments, event );
  if( event.getType() === "mousedown" ) {
    var target = event.getDomTarget();
    var detail = null;
    if( target === this._searchIconElement ) {
      detail = "search";
    } else if( target === this._cancelIconElement ) {
      this.setValue( "" );
      detail = "cancel";
    }
    if( detail != null ) {
      rwt.remote.EventUtil.notifyDefaultSelected( this, 0, 0, 0, 0, detail );
      this._forceFocus(); //force focus after search or cancel icon event
    }
  }
}`
