Hi Nishant,
ULCTextField doesn't
have an api (to add TextVerifier and PlainDocument) like JTextField
so is
there any way by which I can add both to ULCText field.
A ULC application runs on the server whereas the user interface of an
ULC application runs on the client.
Consider a ULC application that somewhere in its logic sets a new text
in a ULCTextField. The ULCTextFields sends this new text over the
network to his counter piece on the client side, i.e. to a
UITextField. The UITextField then delegates this new text to the user
interface element, i.e. a JTextField.
This mechanism happens for
* state changes on the server: ULCTextField notifies UITextField which
itself notifies JTextField
* state changes on the client: JTextField notifies UITextField which
itself notifies ULCTextField
* events on the client: JTextField notifies UITextField which itsefle
notifies ULCTextField
For all cases this means sending data over a network. As this is an
expensive operation it is not meaningful to use this mechanism for
frequent operations. We consider operations on the PlainDocument and
on the TextVerifier as frequent therefor the API is not available on
the server-side API.
ULC provides data types as a replacement for PlainDocuments and
TextVerifiers: e.g. ULCDateDataType, ULCNumberDataType,
ULCRegularExpressionDataType.
You can implement custom data types if the functionality of the
existing data types is not sufficient.
