jEdit 4.0pre1

preContentRemoved

public void preContentRemoved(Buffer buffer,
                              int startLine,
                              int offset,

Called when text is about to be removed from the buffer, but is still present.

Specified by:

preContentRemoved in interface BufferChangeListener

contentRemoved

public void contentRemoved(Buffer buffer,
                           int startLine,
                           int offset,
                           int numLines,
                           int length)

Called when text is removed from the buffer.

Specified by:

contentRemoved in interface BufferChangeListener

Parameters:

buffer - The buffer in question

startLine - The first line

offset - The start offset, from the beginning of the buffer

numLines - The number of lines removed

length - The number of characters removed

Since:

jEdit 4.0pre1

transactionComplete

public void transactionComplete(Buffer buffer)

Called after an undo or compound edit has finished. The text area uses this event to queue up and collapse cleanup operations so they are only run once during a long transaction (such as a "Replace All" operation.)

Specified by:

transactionComplete in interface BufferChangeListener

Parameters:

buffer - The buffer in question

Since:

jEdit 4.0pre6

foldHandlerChanged

public void foldHandlerChanged(Buffer buffer)

Called to notify the text area that folds need to be collapsed if the "collapseFolds" property is set. This method is called after the buffer has been loaded, and also if the user changes the fold handler.

Specified by:

foldHandlerChanged in interface BufferChangeListener

Parameters:

buffer - The buffer in question
