 Store Inquiry for the Palm OS Let’s build a searchable store inquiry over a stores table that also allows full update, insert and delete capability. We’ll use the Application Wizard which requires no coding. The finished product will show a form, search panel, result tree all sortable by store name. 1. We start by choosing a Form Wizard component in the Application Builder.
2. The DataWizard for the Form appears. We walk through table selection, selecting the Stores tables.
3. We define search and query result settings.
4. Now
layout the form visually. 5. JDesignerPro creates all the Java code, forms components, SQL, server messaging, JDBC calls and component interactions for us. It then draws the form on the screen, complete with buttons. This is exactly how the form will look on a Palm Pilot. We can now customize this form if desired or keep it as is.
6. By
pressing the compile button we go to the preliminary view
of the finished screen. Notice that the compiled screen
is already live to the database and looks identical to
the screen on the right side Application Builder picture
above. JDesignerPro is truly WYSIWYG. 7.By
clicking on one of the stores in the Result List the app
will automatically switch to the details tab and load the
details for the selected store as shown here. That’s it! This screen is done in about 10 minutes and is ready to deploy. Notice that we did not enter any Java code or even look at things like interactions and object properties, etc. Although those things are readily accessible for advanced users. Notice also that unlike most of the competing products JDesignerPro allows you to navigate through resulting data using a smart tree structure. Most IDEs use VCR style controls which in the real world are virtually useless unless you have only 20 records in your database table. Note: Above we have referred to competing products. These refer to products that create applications that run in a browser. As far as we know there are no competing products that create appplications such as these on a Palm Pilot or Windows handheld device. |
