Hi all,
i am developing rap application.
I am facing problem in selecting of particular date

omposite container = new Composite(parent, SWT.NONE);
GridLayout layout = new GridLayout(5, false);
container.setLayout(layout);
container.setLayoutData(new GridData(GridData.FILL_BOTH));
final DateTime calendar = new DateTime (container, SWT.CALENDAR | SWT.BORDER);
final Label selectedDate = new Label(parent, SWT.NONE);
final DateFormat fmt = SimpleDateFormat.getDateInstance(DateFormat.LONG);
calendar.addSelectionListener(new SelectionAdapter(){
public void widgetSelected(SelectionEvent e) {

String date=(calendar.getMonth () + 1) + "/" + (calendar.getDay ()) + "/" + (calendar.getYear ());
selectedDate.setText(date);
selectedDate.getParent().layout();
}
});
return selectedDate;
this is my code.i want to get date from this function to my text box like which we have in all web applications
(mena in clicking on calender button we get the calender and on seltion of praticular date it will come automatically in text box)
Please help me to resolve it.

Marie,

I'm sorry but I do not understand what your problem is. I've pasted your example code into a simple RWT standalone app and it worked as expected (see attached screenshot). Could you please elaborate a little bit on what you are trying to achieve? Note that I've tested this against CVS-Head, maybe you're using an older version?

Regards
Frank

Hi again,

I think you like to do something like shown in the attached screenshot (datepicker2.png). I've attached the class that implementes my screenshot example.

The idea is that you provide a simple date selection service that is registered by both - UI1 and UI2. UI1 contains the datepicker that actually triggers the service in case the date was changed by the user. UI2 listens to notifications and updates the textfield accordingly. Please have a look at the attached source file for more details.

In case you want to use this in the workbench and you have trouble to decide where to store the service: the simplest approach would be to store this in the session using the SessionSingletonBase#getInstance(Class) approach. Note the latter may have some downsides due to coupling reasons and there are more sophisticated solutions, but without knowing the exact purpose it's difficult to give a more appropriate advice.

Hope that helps
Frank
