How can i get widget which has focus

[karthik.intels12]

Hi,

I have a widget in a editor. I have set focus on text box and I need to get that widget. i have used Some API to get that widget from UI which it has focus. But i want the text which is present in that text box. Is that possible to get the text from the widget. I cannot use named widgetlocator for that textbox because it has created very generic way across the tool.


I have attached the Snippets. Just go through it and give me ur valuable suggestion...

// Using mouse click key board shortcut i'm somehow setting focus on widgets

this.ui.keyClick(WT.SHIFT + WT.TAB);
this.ui.keyClick(WT.CTRL, 'A');
this.ui.keyClick(WT.DEL);
this.ui.enterText("100");

// In thread I'm trying to access that widget
Display.getDefault().syncExec(new Runnable() {
@Override
public void run() {

// here getFocusControl() returning the widget which has current focus and i'm getting that widget as text too.. but i don have any API to get text from the widget

Control focusControl = Display.getCurrent().getFocusControl();
//Shell shell = focusControl.getShell();
// String text = shell.getText();
//System.out.println(text);
}
});


Now i need that 100 to assert check... Please give me ur valuable suggestion.

To get the text of a generic control, you'll have to do some conditional testing since there is no convenient interface to cast controls with text to. In other words, something like this:

Code: Select all

import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Group;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Text;


public class TextUtil {
   
   public static String getText(final Control c){
      final String text[] = new String[1];
      Display.getDefault().syncExec(new Runnable() {
         public void run() {
            if (c instanceof Button)
               text[0] = ((Button)c).getText();
            else if (c instanceof Group)
               text[0] = ((Group)c).getText();
            else if (c instanceof Label)
               text[0] = ((Label)c).getText();
            else if (c instanceof Text)
               text[0] = ((Text)c).getText();
            //etc
         }
      });
      return text[0];
   }
}

To make a safe assertion, you'll want to wrap the text access in a condition something like this:

Code: Select all

import org.eclipse.swt.widgets.Control;

import com.windowtester.runtime.condition.ICondition;
import com.windowtester.runtime.util.StringComparator;

public class ControlHasTextCondition implements ICondition {

   private final Control c;
   private final String expected;

   public ControlHasTextCondition(Control c, String expected) {
      this.c = c;
      this.expected = expected;
   }

   /*
    * (non-Javadoc)
    *
    * @see com.windowtester.runtime.condition.ICondition#test()
    */
   public boolean test() {
      return StringComparator.matches(TextUtil.getText(c), expected);
   }

}

Putting it all together, you'd get an assertion like this:

Code: Select all

Control focusControl = Display.getCurrent().getFocusControl();
ui.assertThat(new ControlHasTextCondition(focusControl, expectedText);

where expectedText is the text you expect the focus control to have.
