Hi Mark,
Well, the job of the renderer is to basically "translate" the data
into a visual representation. So, if you write a custom renderer to
take your data which is a component with a Label and render that, then
great! But note that the usual way to write a renderer is to have it
setup its own internal components, set their data values based on the
data in the list and let them render themselves to the graphics object.
So, no your data doesn't have to be just text, but I think I would
just make a small custom Java object that contains the text you want to
display, along with something you can use to decide the color and make
that your data object. Then the renderer would just contain a Label
component for which you set the text and the foreground color based on
your list data and just have this single Label render itself. In fact,
if you look at the default renderer for a Spinner
(SpinnerItemRenderer.java) it is just subclassed from a Label with the
additional methods needed to implement the Spinner.ItemRenderer
interface. You could easily duplicate this logic with just a few
changes and (I think) achieve the effect you want.
Let us know how you get on with this.

Hi Roger,
Ideally I would just make the Data another component and add a label.
But if that is difficult and it has to be text then I will just add a
HEX colour in the start with a delimiter. (In my code I already have
Status broken down into standard Warning,Info,Fine,Finer etc... )

Mark.

Hi Mark,
You can make a custom SpinnerItemRenderer, and call
spinner.setItemRenderer(myCustomRenderer). I guess my question would
be: how are you going to tell (from the data) what color to make it?

Hi Roger,
Thanks for your reply... to enable me to change the colour of the text
in the list any ideas?
I had a look at modifying the numericspinnerdata object but it does
only seem to get the String...
I could rewrite a component Spinner? Based off the Spinner code... but
seems like a fair bit of work;
Anyway for other code to add to a spinner is (Still can't get
SetSelectedItem to work...):
ArrayList<String> mMessages = new ArrayList<String>();
public boolean addStatusMessage(String vStatus)
{
mMessages.add(vStatus);
ApplicationContext.queueCallback(new
TaskAddSpinnerMessage(mTRNGUIWindow.mStatusSpinner, mMessages), true);
return true;
}
/** */
private class TaskAddSpinnerMessage implements Runnable
{
Spinner mSpinner;
ArrayList<String> mMessage;
public TaskAddSpinnerMessage (Spinner vSpinner,ArrayList<String> vMessage)
{
mMessage = vMessage;
mSpinner = vSpinner;
}
public void run ()
{
mSpinner.setSpinnerData(mMessage);
mSpinner.setSelectedItem(mMessage.get(mMessage.getLength()));
}
}
Regards,
Mark.

Hi Mark,
The data for a Spinner should be a
org.apache.pivot.collections.List of something (and it could be an
unknown or List<?>). The default list for a Spinner is an immutable
list, so trying to add to it won't work. And adding a Label component
won't be necessary either because the skin just wants to call the
"toString()" method of the list element in order to render it.
So, the right thing would be to keep your List<String> spinnerData
= new ArrayList<String>(); separately, then add the string data to it
as you get more text. Just call "setSpinnerData(spinnerData)" once,
and the spinner itself will update its display as you add data to the
data list (that's why it has to be a Pivot List, so the component gets
notified of changes to the data itself.

P.S. It would be better create a new email thread than replying to an
earlier, unrelated posting. Thanks.

Hi All,
Anybody know how to set values into a spinner from JAVA code?
(Should be easy just having problems...bit vague of how to use <?>
wildcards... and assume there is an easier way)
I need to add Lines of Text? (Using is for my apps logging
interface, to keep a history of logged actions...) (Also being
able to change the colour would be good too;])
//For example...
String vMessage = "Hello!";
mSpinner.getSpinnerData().add(vMessage);
//Or
Label vMessage = new Label("Hello");
mSpinner.getSpinnerData().add(vMessage);

*Subject:* RE: Alerts loosing Focus When using Context Menu Items
Hi,
We had similar problems in our application. The issue is that
the process of closing the context menu puts focus back on the
window it was invoked from, which takes focus away from the alert
or popup or any other dialog, for that matter. We have a
workaround, which involves a custom skin for the menu popups.
Maybe you could open up a JIRA issue for your case and we can
work on getting a better fix into the next release. But, probably
we can put the workaround into that issue so you can try it (at
least for now).
Thanks,

*Subject:* Alerts loosing Focus When using Context Menu Items
Hi,
I am popping up one Alert message using Context Menu Items. Alert
is coming fine, But Once Alert message popped up, it is loosing
its Focus. Can Any help me in how to make sure Alert should not
loose focus when they are opened from Context Menu Items. Code
that i have used for this functionality is as follows:
Action.getNamedActions().put("openAction", new Action() {
@Override
public void perform(Component source) {
Alert.alert("Opening.", MyClass.this.getWindow());
}
});
Here MyClass is the Class Name in which iam using this code and
this MyClass extends BoxPane and "openAction" is a Menu.Item .
