-Move MoveElementsCommand class from diagramcommands file to
movegraphicsitemcommand file.
-Rename the to class MoveGraphicsItemCommand.
-Minor code change to make it more modern.
In the diagram editor, when we edit the element information in the side
panel, each time we tip something in the text field the cursor always go
to the end if the "label" information is empty.
Because strange behaviour with Qt::key_space if used for keyPressEvent
and also in shortcut.
Now the shortcut for the rotate action is ctrl + R and key_space to
rotate terminal on the fly before placing it in the drawing.
The rotate action shortcut was 'space' before this commit and so the
keyPressEvent with space key was never propagated because always grabbed
by the rotate action.
Now the shortcut for the rotate action is ctrl + space.
Note that even if rotate exist in element editor, this doesn't work well
because the rotation is not well managed by the save/load from elmt
file.
Since this commit, the terminals can't be moved from the tree widget,
instead we need to use the "move in" widget to move one or several
selected terminals in the table view.
