delete_tag Callback Type
Function prototype:
function funcname (doc, tagname, oid, op)
delete_tag is called before a Delete Markup operation is done in the Edit window.
Arguments
• doc is the identifier of the document in which the Delete Markup was attempted and can be used to derive the cursor position and/or the selected region.
• tagname is the name of the tag that will be deleted (generally, to the left of the caret position).
|
|
If the document type definition for your document instance includes the NAMECASE GENERAL NO setting, then the tagname parameter will be case-sensitive.
|
• oid is the object identifier of the element to be deleted.
• op is the function callback operation. Callbacks are called twice in succession with op specifying the stage of callback operation.
1. op == 1 first call — The returned argument specifies whether the execution should continue or be stopped:
▪ 0 — Continue callback processing.
▪ -1 — Stop further callback processing.
2. op == 2 second call — Occurs unless the processing was stopped during the first call. The returned argument allows or prevents basic Arbortext Editor processing after all callbacks have been called:
▪ 0 — Basic Arbortext Editor processing allowed.
▪ -1 — Basic Arbortext Editor processing prevented.
