Called when text is about to be inserted in the buffer.

Specified by:

preContentInserted in interface BufferListener

Parameters:

jEdit 4.3pre11

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

Since:

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
