This scenario is part of Actions Example 11: Window with Separate Search Dialog. To get a dialog that can act as a permanent toolbar to assist in queries in a Reservations window:
| 1. | Create a new subclass of the Dialog Box class, rename it to "FindExistingReservations". |
| 2. | In the Controls Group, insert a text box with prompt: Destination, and set the Related Column property to: |
TOUR.DESTINATION
A lookup button appears that calls a lookup window for Tours.
| 3. | Insert a text box with prompt: Customer Name, and set the Related Column property to: |
PERSON.FAMILY_NAME
| 4. | Rename the OK and Cancel buttons to "Find" and "Close" respectively, and reposition them if required. |
| 5. | Open the Object Activator for the Action property of the Find button, remove the dialog-ok() action, and compose this method call script: |
myReservations.QueryDefine()
myReservations.query.destination(Variables.Text_Box_1() )
myReservations.query.family_name(Variables.Text_Box_2() )
myReservations.QueryExecute()
In this script, "myReservations" is a user-defined property of the dialog class. It represents a window object, not a string. Here are the steps for writing this script:
| 1. | Make sure the FindExistingReservations dialog is selected in the Object Browser tree view (top-left). |
| 2. | In the Methods pane, click the Properties tab page, and click New. |
| 3. | In the New Property dialog, specify Name = myReservations, Type = Reservations, accept 1 as the Argument Position, and click OK. |
| Because you specified a new property with an object-like type, a new node for myReservations is added to the Object Browser pane. |
| 4. | Back in the Object Activator, click the myReservations object in the Object Browser, then select the QueryDefine() method, and then click Add. |
| 5. | In the Object Browser pane, select the "myReservations.query.destination" column object, and then click Add. |
| 6. | Select the empty parameter node of the newly added method call, select the "Variables.Text_Box_1" object, and then click Set. |
| 7. | Follow the same steps to produce the method call passing the customer name. |
| 8. | Finally, add the "myReservations.QueryExecute() call and click OK to exit the Object Activator. |
Continue with Reservations Window.
