Dialogs supporting several languages The strings of a Dialog can be localized, see the Developer's Guide chapter Dialog Localization. Events OpenOffice.org dialogs and forms are based on an event-oriented programming model where you can assign event handlers to the control elements. An event handler runs a predefined procedure when a particular action occurs. You can also edit documents or open databases with event handling as well as access other control elements. OpenOffice.org control elements recognize different types of events that can be triggered in different situations. These event types can be divided into four groups: Mouse control: Events that correspond to mouse actions (for example, simple mouse movements or a click on a particular screen location). Keyboard control: Events that are triggered by keyboard strokes. Focus modification: Events that OpenOffice.org performs when control elements are activated or deactivated. 156 OpenOffice.org 3.2 BASIC Guide · March 2010
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.
