Change color of event.

[evalls]

Hi sebfz1 please i have 2 questions,
1- how can i Change the Color of a CalendarEvent?
2- when i use a downloadlink i can generate a file for the user like This:

DownloadLink link = new DownloadLink(wicketID, new AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;

        @Override
        public File getObject() {
            File tempFile;
            try {
                tempFile = File.createTempFile("test", ".csv");
                InputStream data = new ByteArrayInputStream("some calendarEvent".getBytes());
                Files.writeTo(tempFile, data);

            } catch (IOException e) {
                throw new RuntimeException(e);
            }

            return tempFile;
        }
    }
    ).setCacheDuration(Duration.NONE).setDeleteAfterDownload(true);
    return link;
}

how can i do it in a onsubmit methode of a button: i am trying to export my CalenderEvents?

I hope you will help me..........

For 2) see https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/markup/html/link/DownloadLink.java#L152-L185

For 1) I see there is a setter - https://github.com/sebfz1/wicket-jquery-ui/blob/master/wicket-jquery-ui-calendar/src/main/java/com/googlecode/wicket/jquery/ui/calendar/CalendarEvent.java#L166

is there some thing to pay attention again when i export CalendarEvent. I use what you show me and i'm getting this error:

Wicket.Ajax.Call.failure: Error while parsing response: Not Found

Hi,

Additionally if you would like to change the color in a lazy way (when these are loaded by the model) you could make YourCalendarModel implements ICalendarVisitor.

Best regards,
Sebastien

My onSubmit() look like this:

@OverRide
public void onSubmit(AjaxRequestTarget target)
{

          final File file = new File("myfile"); // that is just a test
    if (file == null)
    {
        throw new IllegalStateException(getClass().getName() +
            " failed to retrieve a File object from model");
    }


    String fileName = fileNameModel != null ? fileNameModel.getObject() : null;
    if (Strings.isEmpty(fileName))
    {
        fileName = file.getName();
    }

    IResourceStream resourceStream = new FileResourceStream(
        new org.apache.wicket.util.file.File(file));
                    Duration cacheDuration = null;
    getRequestCycle().scheduleRequestHandlerAfterCurrent(
        new ResourceStreamRequestHandler(resourceStream)
        {
            public void respond(IRequestCycle requestCycle)
            {
                super.respond(requestCycle);
                                boolean deleteAfter = false;

                if (deleteAfter)
                {
                    Files.remove(file);
                }
            }
        }.setFileName(fileName)
            .setContentDisposition(ContentDisposition.ATTACHMENT)
            .setCacheDuration(cacheDuration));


                    }

The error message is not clear enough to me to identify the issue.
I don't exactly how your code looks like, but to export datatable rows for instance, I have the following:
https://github.com/sebfz1/wicket-jquery-ui/blob/master/wicket-kendo-ui/src/main/java/com/googlecode/wicket/kendo/ui/datatable/export/CSVDataExporter.java (itself based on wicket's CSVDataExporter).

The usage is as simple as: `@ Override public void onSubmit() { CSVDataExporter.export(myTable, "table.csv"); }

Maybe can you get inspiration from this, replacing the DataTable/IDataProvider by Calendar/CalendarModel...
