Figure 428: Assign action dialog box

Macros can also be assigned to events relating to the form as a whole. To assign

these, right-click on a form control in the document, select Form and click on the

Events tab.

Read-only documents

Having created your form, you want whoever is using it to be able to access the

information stored in the database, or complete the form, without changing the

layout. To do this, make the document read-only by selecting Tools > Options >

OpenOffice.org > Security> Open this document in read only mode.

Fine-tuning database access permissions

By default, when a database is accessed from a form, any changes can be made to it:

records can be added, deleted, and amended. You may not want that behavior. For

example, you may want users to be able only to add new records or to be prohibited

from deleting existing records.

In design mode, right-click on a form control and select Form from the pop-up menu.

On the Data tab of the Form Properties dialog box are a number of options: Allow

additions, Allow deletions, Allow modifications and Add data only. Set each of these to

Yes or No to control the access users have to the data source.

Individual fields can also be protected. This might be useful if you wanted a user to

be able to modify some parts of a record but only view others, such as a stock list

where item descriptions are fixed and quantities can be modified.

To make an individual field read-only, in design mode, right-click on the form control

within the document and select Control from the pop-up menu. Select the General

tab and set Read-only to Yes.
