GWT - How to allow only numbers in TextItem?

I have the following TextItem: 

final TextItem txtFromAmt = new TextItem();
txtFromAmt.setWrapTitle(false);
txtFromAmt.setShowTitle(false);
txtFromAmt.setAlign(Alignment.LEFT);
txtFromAmt.setWidth(100);

I want this TextItem to only allow numbers. How can I do that? Is there any property/method of TextItem to do that?

Solution

  • Please check the below documentation.

    https://www.smartclient.com/smartgwt/javadoc/com/smartgwt/client/widgets/form/fields/TextItem.html#setKeyPressFilter-java.lang.String-

    As suggested by El Hoss try the same

    txtFromAmt.setKeyPressFilter("[0-9.]"); // allows only digits and .(dot)
