Phone number tabbing in Text field using Jface - jface

Question

I am stuck in one of the issue. Suppose i have a phone number field 010-9999-9999, this number should split in 3 text field. I tried to do this but i get only prefix number i.e 010 in all three text field. I am using jface databinding.
I created Model as
class A{
String phoneNo;
}
Jface Databinding:
IObservableValue ssn1TextTextObserveWidget = SWTObservables.observeText(text_ph11, SWT.Modify);
IObservableValue ssn2TextTextObserveWidget = SWTObservables.observeText(text_ph2, SWT.Modify);
IObservableValue ssn2TextTextObserveWidget1 = SWTObservables.observeText(text_ph3, SWT.Modify);
IObservableValue simpleTableViewerSSN1ObserveDetailValue = BeansObservables.observeDetailValue(simpleTableViewerSelectionObserveSelection_employee, "phoneNo", String.class);
IObservableValue simpleTableViewerSSN2ObserveDetailValue = BeansObservables.observeDetailValue(simpleTableViewerSelectionObserveSelection_employee, "phoneNo", String.class);
IObservableValue simpleTableViewerSSN2ObserveDetailValue = BeansObservables.observeDetailValue(simpleTableViewerSelectionObserveSelection_employee, "phoneNo", String.class);
Databinding
bindingContext.bindValue(simpleTableViewerSSN1ObserveDetailValue, ssn1TextTextObserveWidget, null, null);
bindingContext.bindValue(simpleTableViewerSSN2ObserveDetailValue, ssn2TextTextObserveWidget, null, null);
bindingContext.bindValue(simpleTableViewerSSN2ObserveDetailValue, ssn2TextTextObserveWidget1, null, null);
When i try to do this value only prefix get populated in all three fields i.e 010-010-010. Please help me out to resolve this issue.

Answer 1

If you want your phone number to be divided into three different widgets you will probably need to save the phone number in three different attributes, each assigned a different part of the phone number.
There might be some way to bind a 'part' of a string value to a widget, maybe through getter methods, but for that wait and let someone more knowledgeable in this area give an answer for you.

Here is sample code that can be modified to work with your case. IConverter is used with UpdateValueStrategy to modify the value that will be set/get model to/from target text feild.
//GUI class
final Display display = new Display();
final Shell shell = new Shell(display);
shell.setLayout(new GridLayout(3, false));
Label lbl = new Label(shell, SWT.NONE);
lbl.setText("Name");
final Text firstName = new Text(shell, SWT.BORDER);
final Text lastName = new Text(shell, SWT.BORDER);
final Name name = new Name();
SWTObservables.getRealm(display).exec(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
Realm realm = SWTObservables.getRealm(display);
DataBindingContext cxt = new DataBindingContext(realm);
ISWTObservableValue firstNameObservable = SWTObservables.observeText(firstName, new int[] { SWT.Modify });
ISWTObservableValue lastNameObservable = SWTObservables.observeText(lastName, new int[] { SWT.Modify });
final IObservableValue nameObservable = BeansObservables.observeValue(realm, name, "name");
UpdateValueStrategy firstNameTxtToName = new UpdateValueStrategy();
firstNameTxtToName.setConverter(new IConverter() {
#Override
public Object getToType() {
// TODO Auto-generated method stub
return String.class;
}
#Override
public Object getFromType() {
// TODO Auto-generated method stub
return String.class;
}
#Override
public Object convert(Object fromObject) {
String val = fromObject.toString();
Object beanVal = nameObservable.getValue();
if (beanVal != null) {
String beanString = beanVal.toString();
int i = beanString.indexOf(',');
if (i != -1) {
return val + beanString.substring(i);
}
}
return val;
}
});
UpdateValueStrategy nameToFirstName = new UpdateValueStrategy();
nameToFirstName.setConverter(new IConverter() {
#Override
public Object getToType() {
// TODO Auto-generated method stub
return String.class;
}
#Override
public Object getFromType() {
// TODO Auto-generated method stub
return String.class;
}
#Override
public Object convert(Object fromObject) {
if (fromObject != null) {
Object objVal = nameObservable.getValue();
if (objVal != null) {
String val = objVal.toString();
int i = val.indexOf(',');
if (i != -1) {
return val.substring(0, i);
} else {
return val;
}
}
}
return "";
}
});
UpdateValueStrategy lastNameTxtToName = new UpdateValueStrategy();
lastNameTxtToName.setConverter(new IConverter() {
#Override
public Object getToType() {
// TODO Auto-generated method stub
return String.class;
}
#Override
public Object getFromType() {
// TODO Auto-generated method stub
return String.class;
}
#Override
public Object convert(Object fromObject) {
String val = fromObject.toString();
Object beanVal = nameObservable.getValue();
if (beanVal != null) {
String beanString = beanVal.toString();
int i = beanString.indexOf(',');
String fName = beanString;
if (i != -1) {
fName = beanString.substring(0, i + 1);
} else {
fName = fName + ",";
}
val = fName + val;
}
return val;
}
});
UpdateValueStrategy nameToLastName = new UpdateValueStrategy();
nameToLastName.setConverter(new IConverter() {
#Override
public Object getToType() {
// TODO Auto-generated method stub
return String.class;
}
#Override
public Object getFromType() {
// TODO Auto-generated method stub
return String.class;
}
#Override
public Object convert(Object fromObject) {
if (fromObject != null) {
String val = fromObject.toString();
int i = val.indexOf(',');
if (i != -1) {
return val.substring(i + 1);
}
}
return "";
}
});
cxt.bindValue(firstNameObservable, nameObservable, firstNameTxtToName, nameToFirstName);
cxt.bindValue(lastNameObservable, nameObservable, lastNameTxtToName, nameToLastName);
}
});
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
