Control element-specific events: Events that only occur in relation to certain control elements.
When you work with events, make sure that you create the associated dialog in the OpenOffice.org development
environment and that it contains the required control elements or documents (if you apply the events to a form).
The OpenOffice.org Basic development environment
The figure above shows the OpenOffice.org Basic development environment with a dialog window that contains
two list boxes. You can move the data from one list to the other using the buttons between the two list boxes.
Events
If you want to display the layout on screen, then you should create the associated OpenOffice.org Basic
procedures so that they can be called up by the event handlers. Even though you can use these procedures in any
module, it is best to limit their use to two modules. To make your code easier to read, you should assign
meaningful names to these procedures. Jumping directly to a general program procedure from a macro can result
in unclear code. Instead, to simplify code maintenance and troubleshooting, you should create another procedure
to serve as an entry point for event handling - even if it only executes a single call to the target procedure.
The code in the following example moves an entry from the left to the right list box of a dialog.
Sub cmdSelect_Initiated
Dim lstEntries As Object
Dim lstSelection As Object
lstEntries = Dlg.getControl("lstEntries")
lstSelection = Dlg.getControl("lstSelection")
If lstEntries.SelectedItem > 0 Then
lstSelection.AddItem(lstEntries.SelectedItem, 0)
lstEntries.removeItems(lstEntries.SelectItemPos, 1)
Else
Beep
End If
End Sub
If this procedure was created in OpenOffice.org Basic, you can assign it to an event required using the property
window of the dialog editor.
