# Eines de desenvolupament

Inspects objects in LibreOffice documents and shows supported UNO services, as well as available methods, properties and implemented interfaces.

A més, aquesta funcionalitat us permet explorar l'estructura del document a través del Model d'Objectes de Document (DOM, per les seves sigles en anglès).

The Development Tools are visible in all documents of LibreOffice Writer, Calc, Impress and Draw. The display is persistent and remain visible until deselected.

When Development Tools is enabled, a dockable window is shown at the bottom of the screen. This window has two sections:

- Document Object Model tree view: Displays document portions according to the Document Object Model (DOM). Use this section to choose the object to inspect.

- Object inspection panel: Displays the available services, methods, properties and interfaces of the selected object.

This feature is available since LibreOffice 7.2 for Writer, Calc, Impress and Draw.

## Document Model Tree View

The left side of the window contains a Current Selection toggle button, a Refresh button and a tree view that displays all objects in the document.

The behavior of the tree view depends on the status of the Current Selection toggle button:

- Click on Current Selection to display the properties of the object currently selected in the document. Hence, clicking any item in the tree view have no effect.

- Click on Current Selection again to display any item in the tree view and update the contents of the Object Inspection Panel.

The types of objects displayed by the Document Model Tree View depend on the LibreOffice application being used:

Aplicació del LibreOffice | Objectes admesos
--- | ---
Writer | Paragraphs Text Portions in a Paragraph Shapes Tables Frames Graphic Objects Embedded Objects (OLE) Style Families and Styles
Calc | Sheets Shapes per sheet Charts per sheet Pivot tables per sheet Style Families and Styles
Impress | Slides Shapes per slide Master slides Style Families and Styles
Draw | Pages Shapes per page Style Families and Styles

## Object Inspection Panel

The right side of the window is the Object Inspection Panel that displays information about the object being inspected.

Class Name: is the name of the object class.

Use the class name to search more information in the API documentation. For example, the top-level object in a Writer document is an instance of the class SwXTextDocument, which is documented at SwXTextDocument Class Reference.

You can inspect the object further by using the four tabs available that display its Interfaces, Services, Properties and Methods.

The information about the object is organized in columns in each tab. The set of columns displayed depend on the selected tab.

### Pestanya Interfícies

Contains a single column presenting the list of interfaces implemented by the object.

### Pestanya Serveis

Contains a single column presenting the list of services supported by the object.

### Pestanya Propietats

Contains four columns that describe the properties of the object:

- Propietat: mostra els noms de les propietats de l'objecte.

- Value: Displays a textual representation of the current property value.

- Type: Shows the property type.

- Info: display relevant information about the property. For example, a read-only property displays "read-only" in this column.

The Properties tab also includes a text box on the bottom to display the full textual representation of the property value.

### Pestanya Mètodes

Contains four columns that describe the combined list of methods that can be called by the current object:

- Method: Shows the names of all methods of the object.

- Return type: Displays the return type of the object methods. Methods that do not return any value are marked as "void" in this column.

- Paràmetres: mostra la llista de paràmetres que requereix el mètode, a més dels tipus respectius.

- Implementation class: Displays the name of the class where the method is implemented.
