Method Summary

protected DVApplet	getAppletViaCheapTrick() A cheap trick: we need the applet but this method is called from the constructor indirectly so we can't assign the applet to an instance var of the correct type.
protected boolean	readReport(java.lang.String fileName, java.lang.String databasePassword) Reads the named report file or, if it's null, creates a new, empty report.
protected void	receiveResponse(java.net.URLConnection conn)
protected void	saveReportAs() Saves the current report to a URL specified by the user.
protected void	sendData(java.net.URLConnection conn)
protected void	writeReportFile(java.lang.String fileName) Writes the current report to the specified file.

Method Detail

readReport

protected boolean readReport(java.lang.String fileName,
                             java.lang.String databasePassword)

Reads the named report file or, if it's null, creates a new, empty report. Returns true if we need to ask the user for connection info because this is a new report.

Parameters:

fileName -

databasePassword - string to give to report; OK if it's null

Returns:

true if we need to ask the user for connection info

getAppletViaCheapTrick

protected DVApplet getAppletViaCheapTrick()

A cheap trick: we need the applet but this method is called from the constructor indirectly so we can't assign the applet to an instance var of the correct type. However, we passed the applet in as our root pane container.

Returns:

the applet

saveReportAs

protected void saveReportAs()

Saves the current report to a URL specified by the user.

Overrides:

saveReportAs in class Designer

writeReportFile

protected void writeReportFile(java.lang.String fileName)

Writes the current report to the specified file. Also tells the command history the report has been saved so it knows how to report if any changes have been made from this point on.

Overrides:

writeReportFile in class Designer

Parameters:

fileName - a file name

protected void sendData(java.net.URLConnection conn)
                 throws java.io.IOException

                        throws java.io.IOException
