Called when text is inserted into the buffer.

Specified by:

preContentRemoved

public void preContentRemoved(JEditBuffer buffer,
                              int startLine,
                              int offset,
                              int numLines,
                              int length)
Called when text is about to be removed from the buffer, but is still present.

Specified by:
preContentRemoved in interface BufferListener
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 to be removed
length - The number of characters to be removed
Since:
jEdit 4.3pre3

contentRemoved

public void contentRemoved(JEditBuffer buffer,
                           int startLine,
                           int offset,
                           int numLines,
                           int length)
Called when text is removed from the buffer.

Specified by:
contentRemoved in interface BufferListener
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

jEdit 4.3pre3

transactionComplete

public void transactionComplete(JEditBuffer 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 BufferListener
Parameters:
buffer - The buffer in question
Since:
jEdit 4.3pre3

foldHandlerChanged

public void foldHandlerChanged(JEditBuffer 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 BufferListener
Parameters:
buffer - The buffer in question
Since:
jEdit 4.3pre3

bufferLoaded

public void bufferLoaded(JEditBuffer buffer)
Called to notify the text area that the buffer has been reloaded.

Specified by:
bufferLoaded in interface BufferListener
Parameters:
buffer - The buffer in question
Since:
jEdit 4.3pre3
