i created a Dialog with two input fields with the following Code.
public class CCIDDialog extends TitleAreaDialog {
private Text ccidText;
private Text descriptionText;
private String CCID;
private String description;
public CCIDDialog(Shell parentShell) {
super(parentShell);
}
public void create() {
super.create();
setTitle(_title);
setMessage("Bitte geben Sie die CCID "+firstchar+"xxxxxxx und eine Beschreibung ein (max. 7-stellig): ", IMessageProvider.INFORMATION); }
@Override
protected Control createDialogArea(Composite parent) {
Composite area = (Composite) super.createDialogArea(parent);
Composite container = new Composite(area, SWT.NONE);
container.setLayoutData(new GridData(GridData.FILL_BOTH));
GridLayout layout = new GridLayout(2, false);
container.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
container.setLayout(layout);
createCCID(container);
createDescription(container);
return area;
}
private void createCCID(Composite container) {
Label lbtFirstName = new Label(container, SWT.NONE);
lbtFirstName.setText("CCID (ohne "+firstchar+"): ");
GridData dataCCID = new GridData();
dataCCID.grabExcessHorizontalSpace = true;
dataCCID.horizontalAlignment = GridData.FILL;
ccidText = new Text(container, SWT.BORDER);
ccidText.setLayoutData(dataCCID);
}
private void createDescription(Composite container) {
Label lbtLastName = new Label(container, SWT.NONE);
lbtLastName.setText("Beschreibung: ");
GridData dataDescription = new GridData();
dataDescription.grabExcessHorizontalSpace = true;
dataDescription.horizontalAlignment = GridData.FILL;
descriptionText = new Text(container, SWT.BORDER);
descriptionText.setLayoutData(dataDescription);
}
@Override
protected boolean isResizable() {
return true;
}
// save content of the Text fields because they get disposed
// as soon as the Dialog closes
private void saveInput() {
CCID = ccidText.getText();
description = descriptionText.getText();
}
@Override
protected void okPressed() {
saveInput();
super.okPressed();
}
public String getCCID() {
return CCID;
}
public String getDescription() {
return description;
}
}
Is there a way to validate the ccidtext? If the user type more then 7 chars, he must get a notification and should not be able to continue the dialog. I read so lot at the internet but can`t find a solution for this problem.
Thank u so much for your help.

You can use Text.addModifyListener
to add a ModifyListener
which will be called each time the text is changed. You can also use Text.addVerifyListener
to add VerifyListener
which can actually prevent text being entered.
For TitleAreaDialog
you can call setMessage
or setErrorMessage
to display a message in the title area.
You can disable the OK
button on the dialog using:
getButton(IDialogConstants.OK_ID).setEnabled(false);
Note: getButton(xxx)
can return null
if you call it too early in the dialog construction. Buttons are created during the createContents
method after the createDialogArea
method has been called.
So you can access the buttons by overriding createContents
like this:
@Override
protected Control createContents(final Composite parent)
{
Control control = super.createContents(parent);
// TODO access buttons here
return control;
}
