How to append a label on a rectangle created by dbCreateRect()

DesmondLiu

Hi experts,

     Using dbCreateLabel() could only create the label in cellview but not appended on a object (e.g. rectangle).

 Is there any way that I could append a label on a rectangle (i.e. as a children of a rectangle) created by dbCreateRect() (but not rodCreateRect()) ?

    Hi Desmond,

    Add a call to leAttachFig() with the label and rectangle shape database ID's and this will make the label a child of the rectangle. I'm assuming that you are doing this in a layout. Alternatively you should be able to directly update or modify the parent attribute of the parent object's database ID, adding the child ID in a list (since the parent-child relationship can be one-to-many, it is represented as a list).

    Hopefully this answers your question?

    Regards,

    Lawrence.

     The parent-child relationship can used in any of the database viewTypes.  You can change a figure's parent but not its children.

    figId~>parent = parentFigId

    Hi Lawrence,

        Thank you, this exactly answered my question.

    Ted,

        Thank you. I think the key I stuck here is that I don't know I can't change/assign a figure's children so I kept finding a function

    to attach labels on rects.

     Hi Desmond

    The descriptors for which attributes you can change directly (parent) and which are changed through another attribute (children) are found in the Virtuoso Design Environment SKILL Reference under Database Access.

    rectId = dbCreateRect( ... )

    labelId = dbCreateLabel( ... )

    labelId~>parent = rectId

    Hi Ted,

         This is a great idea assigning parent-children relation.

    Thank you for your suggestion.

     

    Wish you a good day.
