File chooser in the property sheet [message #675523] Tue, 31 May 2011 18:26 Go to next message

I am implementing a workflow editor and I would like to add a file chooser in the property sheet of my application.
For example, when I select a file, I can see its attributes (name, type, ...) and I would like to add its location.
For me, the easiest solution would be to have a "three dots button" on the line File location of the property sheet and when clicking on this button, it would open a file chooser window and save the selected file location in the object's attributes.

Is this possible? How could I do that in another way than enter it manually in the property field?

Thank you.

you can extend PropertyDescriptor and override
public CellEditor createPropertyEditor(Composite parent)
to return an instance of the following class.

public final class FileDialogCellEditor extends DialogCellEditor {

	private final String[] filterNames;
	private final String[] filterExtensions;
	private final String filterPath;
	private final String dialogText;

	public FileDialogCellEditor(Composite parent,
	        		    String[] filterNames,
				    String[] filterExtensions,
				    String filterPath,
				    String dialogText) {
		this.filterNames = filterNames;
		this.filterExtensions = filterExtensions;
		this.filterPath = filterPath;
		this.dialogText = dialogText;


	protected Object openDialogBox(Control cellEditorWindow) {
		FileDialog dialog = new FileDialog(cellEditorWindow.getShell());

		String absolutePath =;
		return absolutePath;

Hi Christian,

I have tried your solution, but the Choose button does not appear in the Property Sheet in order to open the Dialog box. Could you please explain further?
