AHELP for CIAO 4.9 ChIPS v1

delete_label

Context: labels

Synopsis

Delete the specified label.

Syntax

delete_label()
delete_label(id)

Description

The function arguments.

Argument Description
id A ChipsId structure identifying the item, or a string containing the name of the object.

If no argument is given then the current label is deleted, otherwise the argument determines what to delete.

Example 1

chips> add_label(0.4, 0.5, r"area={\pi}r^2")
chips> delete_label()

Create a label, then delete it.

Example 2

chips> id = ChipsId()
chips> add_label(.35,.9,"The top of the frame.", "id=top")
chips> add_label(.35,.1,"The bottom of the frame.","id=bot")
chips> id.label = "top"
chips> delete_label(id)

Two labels are created; the second label is current after it is created. The id.label command sets the label value of the ChipsId structure to the first label. That label is then deleted.

Example 3

chips> add_label(.35,.9,"The top of the frame.", "id=top")
chips> add_label(.35,.1,"The bottom of the frame.","id=bot")
chips> delete_label("all")

Two labels are created, then the delete_label command deletes them both.
