* @brief The CrossRefItem class
|
|
* This clas provide an item, for show the cross reference, like the contacts linked to a coil.
|
|
* The item setpos automaticaly when parent move.
|
|
* All slave displayed in cross ref will be updated when folio position change in the project.
|
|
* It's the responsability of the master element to informe displayed slave are moved,
|
|
* by calling the slot @updateLabel
|
|
* By default master element is the parent graphics item of this Xref,
|
|
* but if the Xref must be snap to the label of master, the label become the parent of this Xref.
|
|
* This behavior can be changed at anytime by calling setProperties.
