I have a Java Swing application that contains a bunch of frames which in turn predominantly contains tables that display large amounts of data. Since it is always a hassle and its time consuming to arrange all windows and tables on startup, I would like to implement 'workspace'-functionality so that the user can save a setup of preference and on startup choose to automatically load the stored workspace to have all windows and tables appear as previously saved. Specifically, the settings that I wish to store in a workspace are:
- Active windows (JFrame) and their sizes and positions on screen
- Table settings, incl selected columns, column order, column width, sorting, filtering
Does anyone know of a smart and easy way to accomplish this without the obvious, and what seems like a very complex and cumbersome, solution of iterating over all open windows and saving each piece of information with the Preferences api? Thanks
In this case, the obvious solution, java.util.prefs.Preferences, is probably the correct one. RCPrefs from this game is a simple example that demonstrates saving a variety of data types, including enum. The exact implementation is highly dependent on the application. While tedious, it needn't be especially complex. For expedience, the example uses static methods; frame and table preferences are probably worth a class each.
