The IDE has a Run Basic icon in the toolbar that runs the first macro in the IDE.

Unless you change the first macro, it is the empty macro named Main. Modify Main

so that it reads as shown in Listing 6.

Listing 6: Modify Main to call CopyNumToCol1.

Sub Main

CopyNumToCol1

End Sub

Now, you can run CopyNumToCol1 by repeatedly clicking the Run Basic icon in the

toolbar of the IDE. This is very fast and easy, especially for temporary macros that

will be used a few times and then discarded.

Sometimes the macro recorder fails

Understanding the OpenOffice.org internals helps to understand how and why the

macro recorder frequently fails. The primary offender is related to the dispatch

framework and its relationship to the macro recorder.

The dispatch framework

The purpose of the dispatch framework is to provide a uniform access to components

(documents) for commands that usually correspond to menu items. I can use File >

Save from the menu, the shortcut keys Ctrl+S, or click on the Save toolbar icon. All

of these commands are translated into the same “dispatch command”, which is sent

to the current document.

The dispatch framework can also be used to send “commands” back to the UI (User

Interface). For example, after saving the document, the File Save command is

disabled. As soon as the document has been changed, the File Save command is

enabled.

If we see a dispatch command, it is text such as .uno:InsertObject or

.uno:GoToStartOfLine. The command is sent to the document’s frame, and the frame

passes on the command until an object is found that can handle the command.

How the macro recorder uses the dispatch framework

The macro recorder records the generated dispatches. The recorder is relatively

simple to implement and the same commands that are issued are recorded for later

use. The problem is that not all dispatched commands are complete. For example,

inserting an object generates the following code:

dispatcher.executeDispatch(document, ".uno:InsertObject", "", 0, Array())

It is not possible to specify what kind of object to create or insert. If an object is

inserted from a file, you cannot specify which file to insert.

I recorded a macro and used Tools > Options to open and modify configuration

items. The generated macro does not record any configuration changes; in fact, the

generated code is commented so it will not even be run.

rem dispatcher.executeDispatch(document,

".uno:OptionsTreeDialog", "", 0, Array())

If a dialog is opened, the command to open the dialog is likely to be generated. Any

work done inside the dialog is not usually recorded. Examples include macro
