Click the button to open the FileDialog window and select any image to display on a specific label.

The ImageLoader class is used to load images and save images to a file or stream.

ImageData strong> class - device-independent image descriptions

The SWT Image class can be used to display images in a graphical interface.

package rcp_demo.Editor; import org.eclipse.swt.widgets.FileDialog; import org.eclipse.swt.custom.CLabel; import org.eclipse.swt.graphics.Image; import org.eclipse.swt.graphics.ImageData; import org.eclipse.swt.graphics.ImageLoader; public class ProductEditor extends EditorPart { public static final String ID="rcp_demo.Editor.product"; private Text text; private CLabel lbl_image_text; private static final String[] FILTER_NAMES = { "Images(*.jpg)","Images(*.jpeg)","Images(*.png)","All Files (*.*)"}; // These filter extensions are used to filter which files are displayed. private static final String[] FILTER_EXTS = { "*.jpg", "*.jpeg", "*.png", "*.*"}; public void createPartControl(final Composite parent) { parent.setLayout(null); //Layout with absolute positioning components. text = new Text(parent, SWT.BORDER); text.setBounds(25, 57, 169, 19); Button btnOpen = new Button(parent, SWT.NONE); btnOpen.setText("open"); btnOpen.addSelectionListener(new SelectionAdapter() { @Override public void widgetSelected(SelectionEvent e) { FileDialog dialog = new FileDialog(PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell(), SWT.OPEN); dialog.setFilterNames(FILTER_NAMES); dialog.setFilterExtensions(FILTER_EXTS); String result = dialog.open(); if(result!=null) { text.setText(result); Image image=SWTResourceManager.getImage(result); ImageData imgData = image.getImageData(); imgData=imgData.scaledTo(200, 200); ImageLoader imageLoader = new ImageLoader(); imageLoader.data = new ImageData[] {imgData}; imageLoader.save(result, SWT.IMAGE_COPY); System.out.println(imgData.width+"....."+imgData.height); lbl_image_text.setBounds(25,88,imgData.width+10,imgData.height+10); //Image size set to Label //lbl_image_text.setBounds(25,88,image.getBounds().width+10,image.getBounds().height+10); lbl_image_text.setImage(SWTResourceManager.getImage(result)); } } }); btnOpen.setText("open"); lbl_image_text = new CLabel(parent, SWT.Resize); } } 

The CLabel class provides some additional Label class features. This class can display both a text label and an image label.

  lbl_image_text.setText("Welcome"); lbl_image_text.setImage(SWTResourceManager.getImage("Image Path"));
