Right-click the object and click Delete on
the pop-up menu.
Select the object and press the Delete key.
The position and coordinates of an object in a symbol
are relative to the base object. You cannot leave the drawing pane
empty, there must be at least one base object present. The base object
is marked in the Symbol Outline pane with a red underline.
If you delete the existing base object, a dialog box
appears to warn you that you are about to change the base object of
the symbol. You will see this when you delete objects from the symbol
you created in Adding an object, so progressbar becomes
the base object.
To make the progressbar become the base object:
Select the Text object.
Press the Delete key.
Right-click the Shape object and click Delete from
the pop-up menu.
The Confirm New Base Element dialog box opens.
Click Yes.
The progressbar is now the base object for this symbol.
