Constructor Detail

EditPortfolioAction

public EditPortfolioAction(CurrentPortfolio aCurrentPortfolio,
                           JFrame aFrame)

Constructor.

Parameters:

aCurrentPortfolio - contains the stocks in which the user has an interest.

aFrame - parent frame to which this editor is attached (the main window).

Method Detail

actionPerformed

public void actionPerformed(ActionEvent aEvent)

Display a modal dialog, centered on the main window, to allow the user to edit their portfolio of stocks.

If the user selects OK, save any edits and update the display of the main window - otherwise, discard all edits.

The current stocks are presented in a table, along with Add-Change-Delete buttons. The Add button is always enabled, while the Change and Delete buttons are enabled only if a table row is selected.

Add and Change operations will verify input of each field : when focus leaves a field, any invalid input will cause a short message to be placed in the field. Selecting OK while any item is still invalid will cause a message to be displayed, asking for correction before proceeding. The only difference between Add and Change is that the Change operation will pre-populate data entry areas.
