MultilineEdit
MultilineEdit
. It is supposed that this
interface is a front-end for MutableLines
in conjunction with
HotPointControl
, but you may use it freely as it is
necessary for a particular purpose. See
MultilineEditTranslator
for a default implementation.
MultilineEdit
guarantees that each user action results exactly in
a single call of some method of this interface. This allows substitution
of any method, which makes changes in the model, by any number of
other methods in any order, and this will keep all structures
consistent.
If some operation is addressed at the position outside of the stored text, the result may be undefined. The implementation of this interface should not issue any speech output.

putChars
Puts one or several characters at some position. The position expects to be valid in the content of the model, except of the case when there are no lines at all,lineIndex
equals to zero andpos
equals to zero. In this case the method must insert one empty line prior to making any required changes.After performing the operation, the method must prepare the
MultilineEdit.ModificationResult
object. If thechars
arguments has the length greater than one, the string argument of the result must be set to the value ofchars
argument.If
chars
argument has the length equals to one, this single character must be returned as the character argument of the result. If the method is requested to insert a single spacing character, the string argument of the result must contain the last word prior to the inserting position. If there is no any word prior to the inserting position, the result may have the string argument empty.- Parameters:
pos
- The position on the line to put characters atlineIndex
- The index of the line to put characters onchars
- The characters to put- Returns:
- The
MultilineEdit.ModificationResult
object with the flag if the operation was performed and other corresponding information
-
mergeLines
-
splitLine
Splits the specified line at the specified position. This method removes on the line all the content after the specified position and puts the deleted fragment on new line which is inserted just after modified. If the position is given outside of the stored text, the behaviour of this method is undefined.- Parameters:
pos
- The 0-based position to split line atlineIndex
- The 0-based index of the line to split- Returns:
- The fragment moved onto newly inserted line
