Misc Eclipse SWT scripts

1. Move Mouse to X Y location.groovy

import org.eclipse.swt.*;
import org.eclipse.swt.events.*;
import org.eclipse.swt.widgets.*;

def e = new Event();
e.type = SWT.MouseMove
for(int i :  1..50)
{
	e.x = 100 + i * 10;
	e.y = 200 + i;
	eclipse.display.post(e);
	Thread.sleep(10)
}

return 
return e;

return SWT.MouseMove

10. move to textbox, enter text, move to button, click.groovy

view.mouse.move(propertyPage.username_Text)
		          .moveBy(20,10)
				  .click()
				  .keyPress("this is a string")
				  .move(propertyPage.authenticate_Button)
		          .moveBy(20,10).click();;
		          
		          
		          
//code that does the keyPress
	//keyboard events
	public Mouse keyPress(final String text)
	{
		return keyPress(text.toCharArray());
	}
	public Mouse keyPress(final char[] characters)
	{
		for(char character : characters)
			keyPress(character);
		return this;
	}
	public Mouse keyPress(final char character)
	{
		UIThreadRunnable.syncExec(display, new VoidResult() { public void run()
		{
			 Event event = new Event();
		     event.type = SWT.KeyDown;
		     event.character = character;		      
		     display.post(event);
		}});	
		return this;
	}

2. execute JavaScript script.groovy

executing Javascript code from Groovy plugin

def scriptManager = new javax.script.ScriptEngineManager()
def engine = scriptManager.getEngineByName("JavaScript");

def javascript = """

var newTitle = 'This was executed from Javascript ....';
var workbench = org.eclipse.ui.PlatformUI.getWorkbench();
var shell = workbench.getActiveWorkbenchWindow().getShell()

function setText()
{
	shell.text= newTitle;
}

setText();
shell;
"""

return engine.eval(javascript)

3. validate a SWT field to make sure it only has number.groovy

import tm.eclipse.ui.pluginPreferences.pages.*;
import org.eclipse.swt.*;
import org.eclipse.swt.widgets.*;

final def propertyPage = new MainPreferences();
//def propertyPage = new Config();

def viewId =  "test login preferences_2";

eclipseUI.add_View(viewId).close()
def view = eclipseUI.add_View(viewId);
propertyPage.control = view.composite;
propertyPage.createContents(view.composite)

def text = propertyPage.username_Text;


   text.addListener(SWT.Verify, new Listener() 
    {
   public void handleEvent(Event e) {
      String string = e.text;
      char[] chars = new char[string.length()];
      string.getChars(0, chars.length, chars, 0);
      for (int i = 0; i < chars.length; i++) {
         if (!('0' <= chars[i] && chars[i] <= '9')) {
            e.doit = false;
            return;
         }
      }
   }
});

return text

4. create a Jface TreeViewer.groovy

import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.jface.viewers.ITreeContentProvider;
import org.eclipse.jface.viewers.LabelProvider;
import org.eclipse.jface.viewers.Viewer;

def viewId = "file browser 23"
def view = eclipseUI.add_View(viewId);
view.clear()


def treeViewer = view.add.treeViewer();


class ViewContentProvider implements ITreeContentProvider {
    public void inputChanged(Viewer v, Object oldInput, Object newInput) {
    }

    @Override
    public void dispose() {
    }

    @Override
    public Object[] getElements(Object inputElement) {
      return (File[]) inputElement;
    }

    @Override
    public Object[] getChildren(Object parentElement) {
      File file = (File) parentElement;
      return file.listFiles();
    }

    @Override
    public Object getParent(Object element) {
      File file = (File) element;
      return file.getParentFile();
    }

    @Override
    public boolean hasChildren(Object element) {
      File file = (File) element;
      if (file.isDirectory()) {
        return true;
      }
      return false;
    }

  }

  class ViewLabelProvider extends LabelProvider {
    @Override
    public String getText(Object element) {
      File file = (File) element;
      String name = file.getName();
      return name.isEmpty() ? file.getPath() : name;
    }
  }

treeViewer.setContentProvider(new ViewContentProvider());
treeViewer.setLabelProvider(new ViewLabelProvider());
treeViewer.setInput(File.listRoots());

view.refresh();

return treeViewer

5. Text with a ControlDecoration message.groovy

import org.eclipse.swt.*;
import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.jface.viewers.ITreeContentProvider;
import org.eclipse.jface.viewers.LabelProvider;
import org.eclipse.jface.viewers.Viewer;
import org.eclipse.jface.fieldassist.*;
import org.eclipse.swt.layout.*;

def viewId = "test ControlDecoration 1"
def view = eclipseUI.add_View(viewId);
view.clear()



view.set.layout_Grid(2)

view.add.label("Text to the right should have a ControlDecoration");

def image = FieldDecorationRegistry.getDefault().getFieldDecoration(FieldDecorationRegistry.DEC_ERROR).getImage()

def text = view.add.text("some text");

def gridData = new GridData(SWT.FILL , SWT.CENTER, true,false);
gridData.horizontalIndent = 8;
text.setLayoutData(gridData);

def deco = new ControlDecoration(text,SWT.TOP | SWT.LEFT)
deco.setDescriptionText("this is a decoration");
deco.setImage(image);
deco.setShowOnlyOnFocus(false);
deco.marginWidth = 2;
deco.show();

//inspect(deco)

view.add.button("a new button");
view.add.text("another text")




view.refresh();

return deco

6. Same code as 5 but using helper methods.groovy

def viewId = "test ControlDecoration 1"
def view = eclipseUI.add_View(viewId);
view.clear()

view.set.layout_Grid(2)

view.add.button("a new button");
view.add.text("another text")

view.add.label("Text to the right should have a ControlDecoration");

def text = view.add.text("some text").fill_Horizontal();

text.controlDecoration_Set("This is an error message", true); //true shows with error icon (vs info icon)
text.controlDecoration_Hide();

Thread.sleep(1000);
text.controlDecoration_Show();

//view.refresh();
return "done"

7. Text with controlDecoration that validates an URL.groovy

def viewId = "test ControlDecoration 1"
def view = eclipseUI.add_View(viewId);
view.clear()

view.set.layout_Grid(2)

view.add.label("Text with valid URL:");

def text = view.add.text().fill_Horizontal();

text.controlDecoration_Validate_Url("You must enter a valid URL")

return "done"
//Config:UIThread_False

8. glide mouse to number of controls.groovy

import tm.eclipse.ui.pluginPreferences.pages.*;
 
def propertyPage = new MainPreferences();
//def propertyPage = new Config();

def viewId =  "test login preferences_2";
 
eclipseUI.add_View(viewId).close()

def view = eclipseUI.add_View(viewId);
eclipseUI.syncExec( new Runnable()
{ 
	public void run() {
		propertyPage.control = view.composite;
		propertyPage.createContents(view.composite)
	}
});

view.mouse.GLIDE_DELAY_MILISECONDS = 10
view.mouse.GLIDE_DELAY_STEP=5

view.refresh();

eclipseUI.syncExec( new Runnable()
{ 
	public void run() 
	{
		def controls = propertyPage.control.children[0].children[3].children;
		//inspect(controls[3])
		//inspect(controls[5])
//		return controls[3].children[1].toDisplay(1, 1)
		for(def control : controls)
		{
			def position = control.toDisplay(1, 1)
			view.mouse.glide(position);
			Thread.sleep(200);
		}
	}})


return "done";

9. glide mouse and click.groovy

import tm.eclipse.ui.pluginPreferences.pages.*;
 
def propertyPage = new MainPreferences();
//def propertyPage = new Config();

def viewId =  "test login preferences_2";
 
eclipseUI.add_View(viewId).close()

def view = eclipseUI.add_View(viewId);
eclipseUI.syncExec( new Runnable()
{  
	public void run() {
		propertyPage.control = view.composite;
		propertyPage.createContents(view.composite)
	}
});

view.refresh(); 

view.mouse.glide(propertyPage.authenticate_Button)
		          .moveBy(20,10)
				  .click();

return "done";


// code that does the click

	public Mouse click()
	{
		click(SWT.MouseDown,1);		
		sleep(MOUSE_CLICK_DELAY);
		click(SWT.MouseUp,1);		
 		return this;
	}
	
	public Mouse click(final int type, final int button)
	{
		UIThreadRunnable.syncExec(display, new VoidResult() { public void run()
		{
			Event e  = new Event();
			e.type   = type;
			e.button = button;
			display.post(e);
		}});	
		return this;
	}
