Constructor Detail

DataSelector

public DataSelector(IntegratedDataViewer idv,
                    DataSource formulaDataSource)

Create a DataSelector with the given idv and lsit of formulas

Parameters:

idv - The IDV

formulaDataSource - Contains the end-user formulas

DataSelector

public DataSelector(IntegratedDataViewer idv,
                    boolean horizontalOrientation,
                    DataSource formulaDataSource)

Create a DataSelector with the given idv and lsit of formulas

Parameters:

idv - The IDV

horizontalOrientation - Should this be configured with normal dimensions

formulaDataSource - Contains the end-user formulas

DataSelector

public DataSelector(IntegratedDataViewer idv,
                    Dimension defaultSize,
                    boolean singletonDataSource)

Create a DataSelector with the given idv and list of formulas

Parameters:

idv - The IDV

defaultSize - Size of the window

singletonDataSource - Does this dialog just show one data source

Method Detail

setDataSource

public void setDataSource(DataSource dataSource)

Set the data source shown by this selector

Parameters:

dataSource - The data source

getContents

public JComponent getContents()

Return the GUI contents

Specified by:

getContents in class DataSourceHolder

Returns:

The GUI contents

getButtons

public JComponent getButtons()

Return the JComponent that holds the Create and Close buttons.

Overrides:

getButtons in class DataSourceHolder

Returns:

Button panel

dispose

public void dispose()

Remove all references to anything we may have. We do this because (stupid) Swing seems to keep around lots of different references to thei component and/or it's frame. So when we do a window.dispose () this DataSelector does not get gc'ed.

Overrides:

dispose in class DataSourceHolder

removeDataSourceInner

protected boolean removeDataSourceInner(DataSource dataSource)

Remove the specified data source only if it is not the formulaDataSource.

Overrides:

removeDataSourceInner in class DataSourceHolder

Parameters:

dataSource - The data source to remove

Returns:

Did we remove the data source

displayTemplatesChanged

public void displayTemplatesChanged()

Be notified of a change to the display templates

Overrides:

displayTemplatesChanged in class DataSourceHolder

dataSourceTimeChanged

public void dataSourceTimeChanged(DataSource dataSource)

Change the gui when the given data source has changed. This gets called by the IntegratedDataViewer When one of the DataControlDialog-s changes the times on the data source.

Overrides:

dataSourceTimeChanged in class DataSourceHolder

Parameters:

dataSource - The data source that changed

dataSourceChanged

public void dataSourceChanged(DataSource dataSource)

The given data source has changed. This method just re-adds the datasource to force an update of the GUI

Overrides:

dataSourceChanged in class DataSourceHolder

Parameters:

dataSource - The data source that changed

addDataSource

public void addDataSource(DataSource dataSource)

Add the DataSource and its DataChoice-s into the gui

Overrides:

addDataSource in class DataSourceHolder

Parameters:

dataSource - The data source to add

getNameForDataSource

public static String getNameForDataSource(DataSource ds)

A helper method to find the label to use for the given DataSource. If the length of the toString of the data source is less than 30 just use that. Else be a bit smart about truncating it.

Parameters:

ds - The data soruce to get a label for

Returns:

The label

getNameForDataSource

public static String getNameForDataSource(DataSource ds,
                                          int length,
                                          boolean alwaysDoIt)
