Detailed Description

KateUndoManager implements a document's history.

It is in either of the two states:

the default state, which allows rolling back and forth the history of a document, and
a state in which a new element is being added to the history.

The state of the KateUndomanager can be switched using editStart() and editEnd().

◆ KateUndoManager()

KateUndoManager::KateUndoManager ( KTextEditor::DocumentPrivate * doc )

explicit

Creates a clean undo history.

Parameters

doc	the document the KateUndoManager will belong to

Member Function Documentation

◆ editEnd

void KateUndoManager::editEnd ( )

slot

Notify KateUndoManager about the end of an edit.

Definition at line 96 of file kateundomanager.cpp.

◆ editStart

void KateUndoManager::editStart ( )

slot

Notify KateUndoManager about the beginning of an edit.

Definition at line 74 of file kateundomanager.cpp.

◆ lastRedoCursor()

KTextEditor::Cursor KateUndoManager::lastRedoCursor ( ) const

Returns the redo cursor of the last undo group.

Needed for the swap file recovery.

Definition at line 447 of file kateundomanager.cpp.

◆ redo

void KateUndoManager::redo ( )

slot

Redo the latest undo group.

Make sure isDefaultState() is true when calling this method.

Definition at line 281 of file kateundomanager.cpp.

◆ redoCount()

uint KateUndoManager::redoCount ( ) const

Returns how many redo() actions can be performed.

Returns: the number of undo groups which can be redone

Definition at line 260 of file kateundomanager.cpp.

◆ setAllowComplexMerge()

void KateUndoManager::setAllowComplexMerge ( bool allow )

Allows or disallows merging of "complex" undo groups.

When an undo group contains different types of undo items, it is considered a "complex" group.

Parameters

allow whether complex merging is allowed

Definition at line 462 of file kateundomanager.cpp.

◆ setUndoRedoCursorsOfLastGroup()

void KateUndoManager::setUndoRedoCursorsOfLastGroup	(	const KTextEditor::Cursor	undoCursor,
		const KTextEditor::Cursor	redoCursor
	)

Used by the swap file recovery, this function afterwards manipulates the undo/redo cursors of the last KateUndoGroup.

This function should not be used other than by Kate::SwapFile.

Parameters

undoCursor	the undo cursor
redoCursor	the redo cursor

Definition at line 437 of file kateundomanager.cpp.
