La biblioteca ScriptForge
Obrir i seleccioneu el contenidor .
Les biblioteques ScriptForge formen una col·lecció ampliable de recursos per a crear scripts per al LibreOffice, que es poden invocar a partir de macros BASIC o scripts Python.
• Per a carregar macros BASIC cal fer servir la biblioteca ScriptForge mitjançant aquesta expressió:
GlobalScope.BasicLibraries.loadLibrary("ScriptForge")
• Els scripts Python requereixen una importació del mòdul scriptforge:
from scriptforge import CreateScriptService
Invocació dels serveis de l'ScriptForge
Els mòduls i classes descrits s'invoquen a partir d'scripts d'usuari com a «serveis». Amb aquest propòsit, s'ha dissenyat un constructor genèric d'aquests serveis per a cada llenguatge.
El mètode Dispose està disponible en tots els serveis i s'hauria d'invocar per a alliberar de recursos un cop utilitzat:
GlobalScope.BasicLibraries.LoadLibrary("ScriptForge")
Set oSvc = CreateScriptService("servicename"[, arg0, arg1, ...])
' ...
oSvc.Dispose()
from scriptforge import CreateScriptService
svc = CreateScriptService('servicename'[, arg0, arg1, ...])
# ...
svc.Dispose()

The Dialog service contributes to the management of dialogs created with the Basic Dialog Editor or dialogs created on-the-fly. Each instance of the current class represents a single dialog box displayed to the user.
The DialogControl service manages the controls belonging to a dialog defined with the Basic Dialog Editor. Each instance of the current service represents a single control within a dialog box.
The focus is set on getting and setting the values displayed by the controls of the dialog box. Formatting is accessible via the XControlModel and XControlView properties.
Note that the unique DialogControl.Value property content varies according to the control type.
A special attention is given to controls of type tree control. It is easy to populate a tree, either branch by branch, or with a set of branches at once. Populating a tree control can be performed statically or dynamically.
A dictionary is a collection of key-item pairs
The SFDocuments library provides methods and properties to facilitate the management and manipulation of LibreOffice documents.
Methods that are applicable for all types of documents (Text Documents, Sheets, Presentations, etc) are provided by the SFDocuments.Document service. Some examples are:

In Basic scripts, when a run-time error occurs, the methods and properties of the Exception service help identify the error context and allow to handle it.
The FileSystem service includes routines to handle files and folders. Next are some examples of the features provided by this service:
-

-
Get access to the controls inside the form.
-
Get access to subforms of a parent form.
The FormControl service provides access to the controls that belong to a form, a subform or a table control of a FormDocument. Each instance of the FormControl service refers to a single control in the form. This service allows users to:
-
Get and set the properties of the control represented by the FormControl instance.
-
Access the current value displayed by the control.
-
Set the focus on the desired control.
The FormDocument service allows to access form documents stored in LibreOffice Base documents.
