Editing a form

You can open a form in the Form editor as follows:

Choose Open > Form... from the File menu.
OR
In the Structure editor, hold down Ctrl+Shift and double-click the table title whose forms you want to open.
OR
In the Structure editor, right-click on the table name, then select Show Forms... in the context menu.
4D displays the Forms Page of the Explorer. You can expand the "Project Forms" or any of the table names to display the forms associated with them. If you have double-clicked a table’s name or used the context menu of the Structure editor, that table is already selected.
If necessary, expand the table name that contains the form you want to modify.
Right-click on the name of the form to be modified, then select Edit Form... in the context menu.
OR
Select the form then choose Edit Form... in the options menu of the Explorer.
OR
Double-click the name of the form or in the preview area.
4D displays the form in a Form editor window.
Note: These actions are also available on the Home Page of the Explorer.
4D Server: Object locking occurs when two or more users attempt to modify the same form simultaneously. If a user is modifying a form in the Design environment, the form is locked. Other users cannot modify that same form until the first user frees the form by closing it.

Locking information

A closed lock icon () is displayed if objects in the form or the form file are locked. Locking can occur in both project and client/server modes when:

The file for that form is 'Read-only' (Projects only). Clicking on the lock icon will display an alert to unlock it, if possible. If unlocking is successful, the lock icon disappears.
Two or more users attempt to modify the same form at the same time. The form cannot be used until the first user frees it by closing the window (Client/server only).

In both cases, the form can be opened in 'Read-only', but cannot be used until the lock is removed.
