Creating Swing Applications


Before you begin to build Swing applications, you should have read Defining data structures. Swing Applications use these data objects to read and write database tables.


To access large amounts of data, we typically need to navigate precisely through the data, select an entry and then modifying it. For to see what we are talking about: Get an overview about how the sample application "Marketing" is created. Browse the screenshots with links to source and super class Documentation. To test the effect of the used instruction try to get the sample application "Marketing" in package mkt, class Main running.

Administrating big entities (Screenshot)

For navigating (enquiry plus selection of an entry) we use de.must.wuic.ColumnDataListFrame or de.must.wuic.SimpleDataListFrame - sample see mkt.FrKontaktSl. For changing, copying or inserting a new entry we use de.must.wuic.DataPropertyAdministration- sample see mkt.FrKontaktPr.

Important UI components for data input

and more of these components that implement the interface de.must.wuic.DataComponent.

Administrating small entities (Screenshot)

Some entities have view rows and columns. They may be edited in a table sheet. In this case, use de.must.wuic.DataTableAdministration as done in mkt.FrGrPj.

Menu and Toolbar (Screenshot)

To bring the user in touch with your application parts, offer your administrations as a menu item or / and as toolbar button. Menu frames are subclasses of de.must.wuic.MenuFrame like e.g. mkt.MainMenu. You may control entitlements by grouping subject areas and users. See sample mkt.Entitlement, which extends  de.must.middle.EntitlementStd. For flexible access control implement isEntitled(), you may use the current user mkt.CurrentUser to check matching entitlements. Also, toolbar item definitions are used in the sample.
