Hi Daniel
The ULCTextComponent (or rather UITextComponent) triggers a beep because the
initial data is not valid (with regard to its IDataType). I added
http://www.canoo.com/jira/browse/UBA-7131 "Datatypes on text components should
not trigger a beep for initial data from server" to our issue database. Please
note that cell editors are always empty initially. Data is filled in whenever
cell editing starts for a specific cell.
Two things worth mentioning in your example:
a) You are creating a new ULCTextField for every single cell. You can actually
reuse the same textfield for all cells. Actually, you can use the
DefaultCellEditor class to simplify and optimize your code:
ULCTextField tf = new ULCTextField();
tf.setDataType(new ULCRegularExpressionDataType("[09]", "[09]*"));
column.setCellEditor(new DefaultCellEditor(tf));
b) I am not sure what your usage scenario for the regular expression datatype
looks like, but keep in mind: The first regular expression is used to match the
text whenever editing is completed (e.g. focus lost). The second expression is
used to match text which is entered into the text field. Note that this might
also contain multiple characters because of a copy/paste or drag/drop operation.
Cheers
Rolf

>
>
>
> Hello.
>
> We have a little problem using a ULCRegularExpressionDataType for
> validating the user input in tables. When trying to integrate the datatype
> as cell editor for a table and starting the application with speakers
> turned on, you hear the warning audio sound from Windows (XP). When
> scrolling down the sound appears multiple for each table row. This
> behaviour only seems to come up the first time a row is "loaded". Please
> see the snipped below to rebuild the situation. We use ULC version 6.1.1
> and the default sound configuration for Windows XP.
>
> May be we are integrating the datatype the wrong way, so we will be glad,
> if you have any hint or idea to solve this problem.
