TextEditor

Annotations can be edited via a TextEditor instance instead of having to modify the annotation as a string value, which can be difficult as an annotation is in HTML format. A TextEditor for an annotation is provided via the GraphElem method annotationEditor.

Methods

flush( )

Saves all changes to the text, possibly creating an undo record.

replace( string, attributes )

insert( string, attributes )

Inserts string at selectionStart, assigning the given attributes dictionary to the new text, and sets selectionEnd to selectionStart plus the length of string (see the Text Editor Type in Application class for possible attributes keys and values).

remove( )

Deletes the text between selectionStart and selectionEnd and sets selectionEnd to selectionStart.

runStart( )

Searching backwards, finds the first character not matching the attributes at selectionStart starting at selectionStart and returns the index of the next character (as an integer) or zero if the start of the text is reached.

runStart( attributes )

Searching backwards, finds the first character not matching the given attributes starting at selectionStart and returns the index of the next character (as an integer) or zero if the start of the text is reached.

runLimit( )

Searching forward, finds the first character not matching the attributes at selectionStart starting at selectionStart, and returns the index of that character minus the result of calling runStart( ), as an integer.

runStart( attributes )
