Tree view/pl

Wprowadzenie
widok drzewa pojawia się w zakładce w widoku połączonym; pokazuje wszystkie obiekty zdefiniowane przez użytkownika, które są częścią dokumentu FreeCAD. Widok drzewa jest reprezentacją struktury dokumentu i wskazuje, jakie informacje są zapisane na dysku.

Obiekty te niekoniecznie muszą być kształtami geometrycznymi widocznymi w oknie widoku 3D, ale mogą również zawierać obiekty danych utworzone za pomocą dowolnego Środowiska pracy.



Praca z widokiem drzewa
Domyślnie, zawsze gdy tworzony jest nowy obiekt, jest on dodawany na końcu listy w widoku drzewa. Widok drzewa umożliwia zarządzanie obiektami w celu utrzymania ich w zorganizowanym szyku. Pozwala na tworzenie group, przesuwanie obiektów wewnątrz grup, przesuwanie grup wewnątrz innych grup, zmianę nazwy obiektów, kopiowanie obiektów, usuwanie obiektów i inne operacje w menu kontekstowym, które również zależą od aktualnie aktywnego Środowiska pracy.

Many operations create objects that are dependent on a previously existing object. In this case, the tree view shows this relationship by absorbing the older object inside the new object. Expanding and collapsing the objects in the tree view shows the parametric history of that object. Objects that are deeper inside others are older, while objects that are outside are newer, and are derived from the older objects. By modifying the interior objects, the parametric operations propagate all the way to the top, generating a new result.





Działania
expressions and link actions were added in version 0.19.

Since the tree view lists objects that may be visible in the 3D view, many of the actions are the same to those that can be executed from the 3D view.

When the application starts, the default Start Workbench is active, and no document has been created, right clicking on the tree view shows only one command:
 * : Copy selected, Copy active document, Copy all documents, Paste. These allow working with various documents, but are disabled if no document is present.

Once a new document has been created the following become active:
 * : Copy active document, Copy all documents.

In addition, Link actions are available.
 * : Make Link.
 * : Simple group, Group with links, Group with transform links.

Selecting the document
If you select the active document and right click, in addition to and, the following commands appear:
 * : if active, the tree view will show hidden items.
 * : shows an input field to search objects inside the selected document.
 * : closes the selected document by calling the application's method.
 * : if active, the document's objects will not recompute automatically.
 * : if active, the document will allow recompute of only some objects.
 * : marks all objects of the document as touched, and ready for recompute.
 * : creates a group in the selected document by using the document's method.

Selecting objects
Once objects are added to the document then in addition to the previous actions, right clicking on an empty part of the tree view will show additional commands; these depend on the type of object and the active workbench.

For example, with the Draft Workbench active, first select an object, then right click on an empty place in the tree view:
 * : makes the object visible or invisible in the 3D view.
 * : makes the selected objects visible.
 * : makes the selected objects invisible.
 * : makes the object no longer selectable in the 3D view; use again this command to cancel its effect. It sets the object's attribute to  or . Change the property by toggling  in the property editor.
 * : selects all instances of this object in the tree view.
 * : launches the dialog to change color and sizes of lines and vertices, and color of faces.
 * : assigns a random color to the object. It sets the object's attribute to a tuple  with tree random floats between 0 and 1. Change the property by modifying  in the property editor.
 * : disabled if the right-click is not on the object.
 * : copies an object into memory.
 * : pastes the copied object into the document; the copy is added to the end of the tree view.
 * : removes the object from the document, and from the tree view, by calling the document's method.
 * : additional contextual commands provided by the Draft Workbench.

If an object is selected, for example, a Draft Line, and a right click is made in the same object additional commands may be available:
 * : launches the transform widget to move or rotate the object.
 * : sets the colors of the object.
 * : specific command for a Draft Line.
 * : if active, the selected object will be set as hidden.
 * : marks the selected object as touched, and ready for recompute.
 * : recomputes the selected object.
 * : starts editing the name of the selected object. This allows changing the attribute, but not the  attribute, as the latter is read-only.
