Introduction

The Document class represents a pure text document providing methods to modify the content and create views. A document can have any number of views, each view representing the same content, i.e. all views are synchronized. Support for text selection is handled by a View and text format attributes by the Attribute class.

To load a document call KParts::ReadOnlyPart::openUrl(). To reload a document from a file call documentReload(), to save the document call documentSave() or documentSaveAs(). Whenever the modified state of the document changes the signal modifiedChanged() is emitted. Check the modified state with KParts::ReadWritePart::isModified(). Further signals are documentUrlChanged(). The encoding can be specified with setEncoding(), however this will only take effect on file reload and file save.

Text Manipulation

Get the whole content with text() and set new content with setText(). Call insertText() or insertLine() to insert new text or removeText() and removeLine() to remove content. Whenever the document's content changed the signal textChanged() is emitted. Additional signals are textInserted() and textRemoved(). Note, that the first line in the document is line 0.

A Document provides full undo/redo history. Text manipulation actions can be grouped together to one undo/redo action by using an the class EditingTransaction. You can stack multiple EditingTransactions. Internally, the Document has a reference counter. If this reference counter is increased the first time (by creating an instance of EditingTransaction), the signal editingStarted() is emitted. Only when the internal reference counter reaches zero again, the signal editingFinished() and optionally the signal textChanged() are emitted. Whether an editing transaction is currently active can be checked by calling isEditingTransactionRunning().

Note: The signal editingFinished() is always emitted when the last instance of EditingTransaction is destroyed. Contrary, the signal textChanged() is emitted only if text changed. Hence, textChanged() is more accurate with respect to changes in the Document.

Every text editing transaction is also available through the signals lineWrapped(), lineUnwrapped(), textInserted() and textRemoved(). However, these signals should be used with care. Please be aware of the following warning:

Warning: Never change the Document's contents when edit actions are active, i.e. in between of (foreign) editing transactions. In case you violate this, the currently active edit action may perform edits that lead to undefined behavior.

Document Views

A View displays the document's content. As already mentioned, a document can have any number of views, all synchronized. Get a list of all views with views(). Create a new view with createView(). Every time a new view is created the signal viewCreated() is emitted.

Read-Only Mode

A Document may be in read-only mode, for instance due to missing file permissions. The read-only mode can be checked with isReadWrite(). Further, the signal readWriteChanged() is emitted whenever the state changes either to read-only mode or to read/write mode. The read-only mode can be controlled with setReadWrite().

Notifications in Documents and Views

A Document has the ability to show a Message to the user in a View. The Message then is shown either the specified View if Message::setView() was called, or in all Views of the Document.

To post a message just create a new Message and send it with postMessage(). Further information is available in the API documentation of Message.

See also: Message

Crash Recovery for Documents

When the system or the application using the editor component crashed with unsaved changes in the Document, the View notifies the user about the lost data and asks, whether the data should be recovered.

This Document gives you control over the data recovery process. Use isDataRecoveryAvailable() to check for lost data. If you do not want the editor component to handle the data recovery process automatically, you can either trigger the data recovery by calling recoverData() or discard it through discardDataRecovery().

Document Moving Interface

Document Moving Interface allows you to create MovingRange and MovingCursor. A Moving Range or Cursor is a special type of range/cursor because it automatically moves on text insertion or removal. Additionally, one can use the moving ranges to change the color of a particular word or give it a different attribute such as bold. Use newMovingCursor() to create a new moving cursor and newMovingRange() to create a new moving range.

Upon destruction or reload, a document will invalidate all its moving ranges. You can connect to aboutToInvalidateMovingInterfaceContent() signals to know when that is going to happen and delete the cached ranges accordingly.

Document Config

Config provides methods to access and modify the low level config information for a given Document. KTextEditor::Document has support for the following config keys:

backup-on-save-local [bool], enable/disable backup when saving local files
backup-on-save-remote [bool], enable/disable backup when saving remote files
backup-on-save-suffix [string], set the suffix for file backups, e.g. "~"
backup-on-save-prefix [string], set the prefix for file backups, e.g. "."
replace-tabs [bool], whether to replace tabs
indent-pasted-text [bool], whether to indent pasted text
tab-width [int], read/set the width for tabs
indent-width [int], read/set the indentation width
on-the-fly-spellcheck [bool], enable/disable on the fly spellcheck

External modification extension interface for the Document.

The class ModificationInterface provides methods to handle modifications of all opened files caused by external programs. Whenever the modified-on-disk state changes the signal modifiedOnDisk() is emitted along with a ModifiedOnDiskReason. Set the state by calling setModifiedOnDisk(). Whether the Editor should show warning dialogs to inform the user about external modified files can be controlled with setModifiedOnDiskWarning(). The slot modifiedOnDisk() is called to ask the user what to do whenever a file was modified.

doc_marktext

The Mark Interface provides methods to enable and disable marks in a Document, a marked line can be visualized for example with a shaded background color and/or a pixmap in the iconborder of the Document's View. There are a number of predefined mark types, specified in reservedMarkersCount(). Additionally it is possible to add custom marks and set custom pixmaps.

Get all marks in the document by calling marks(). Use clearMarks() to remove all marks in the entire document. A single mark can be retrieved with mark(). To remove all marks from a line call clearMark(). To add and remove marks from a given line use addMark() and removeMark(). It is also possible to replace all marks with setMark(), i.e. setMark() is the same as a call of clearMark() followed by addMark(). The signals marksChanged() and markChanged() are emitted whenever a line's marks changed.

Attention: A mark type is represented as an uint. An uint can have several mark types combined (see above: logical OR). That means for all functions/signals with an uint parameter, e.g. setMark(), removeMark(), etc, the uint may contain multiple marks, i.e. you can add and remove multiple marks simultaneously.

All marks that should be editable by the user can be specified with a mark mask via setEditableMarks(). To set a description and pixmap of a mark type call setMarkDescription() and setMarkPixmap().

Annotation Interface

The Annotation Interface is designed to provide line annotation information for a document. This interface provides means to associate a document with a annotation model, which provides some annotation information for each line in the document.

Setting a model for a Document makes the model data available for all views. If you only want to provide annotations in exactly one view, you can use the AnnotationViewInterface directly. See the AnnotationViewInterface for further details. To summarize, the two use cases are

(1) show annotations in all views. This means you set an AnnotationModel with this interface, and then call setAnnotationBorderVisible() for each view.
(2) show annotations only in one view. This means to not use this interface. Instead, use the AnnotationViewInterface, which inherits this interface. This means you set a model for the specific View.

If you set a model to the Document and the View, the View's model has higher priority.

More information about interfaces for the document can be found in Document Extension Interfaces.

When searching for regular expressions, the first element holds the range of the full match, the subsequent elements hold the ranges of the capturing parentheses.

Parameters

range	Input range to search in
pattern	Text pattern to search for
options	Combination of search flags

Returns: List of ranges (length >=1)

// only make bookmark and breakpoint editable
iface->setEditableMarks( MarkInterface::Bookmark |
                         MarkInterface::BreakpointActive );
 
// or preserve last settings, and add bookmark and breakpoint
iface->setEditableMarks( iface->editableMarks() |
