Detailed Description

A text widget with KXMLGUIClient that represents a Document.

Topics:

Introduction

The View class represents a single view of a KTextEditor::Document, get the document on which the view operates with document(). A view provides both the graphical representation of the text and the KXMLGUIClient for the actions. The view itself does not provide text manipulation, use the methods from the Document instead. The only method to insert text is insertText(), which inserts the given text at the current cursor position and emits the signal textInserted().

Usually a view is created by using Document::createView(). Furthermore a view can have a context menu. Set it with setContextMenu() and get it with contextMenu().

Merging the View's GUI

A View is derived from the class KXMLGUIClient, so its GUI elements (like menu entries and toolbar items) can be merged into the application's GUI (or into a KXMLGUIFactory) by calling

// view is of type KTextEditor::View*

mainWindow()->guiFactory()->addClient( view );

You can add only one view as client, so if you have several views, you first have to remove the current view, and then add the new one, like this

mainWindow()->guiFactory()->removeClient( currentView );

mainWindow()->guiFactory()->addClient( newView );

Text Selection

As the view is a graphical text editor it provides normal and block text selection. You can check with selection() whether a selection exists. removeSelection() will remove the selection without removing the text, whereas removeSelectionText() also removes both, the selection and the selected text. Use selectionText() to get the selected text and setSelection() to specify the selected textrange. The signal selectionChanged() is emitted whenever the selecteion changed.

Cursor Positions

A view has one Cursor which represents a line/column tuple. Two different kinds of cursor positions are supported: first is the real cursor position where a tab character only counts one character. Second is the virtual cursor position, where a tab character counts as many spaces as defined. Get the real position with cursorPosition() and the virtual position with cursorPositionVirtual(). Set the real cursor position with setCursorPosition(). You can even get the screen coordinates of the current cursor position in pixel by using cursorPositionCoordinates(). The signal cursorPositionChanged() is emitted whenever the cursor position changed.

Mouse Tracking

It is possible to get notified via the signal mousePositionChanged() for mouse move events, if mouseTrackingEnabled() returns true. Mouse tracking can be turned on/off by calling setMouseTrackingEnabled(). If an editor implementation does not support mouse tracking, mouseTrackingEnabled() will always return false.

Edit Modes

A view supports several edit modes (EditMode). Common edit modes are insert-mode (INS) and overwrite-mode (OVR). Which edit modes the editor supports depends on the implementation, another well-known mode is the command-mode for example in vim and yzis. The getter viewMode() returns a string like INS or OVR and is represented in the user interface for example in the status bar. Further you can get the edit mode as enum by using viewEditMode(). Whenever the edit mode changed the signals viewModeChanged() and viewEditModeChanged() are emitted.

View Extension Interfaces

A simple view represents the text of a Document and provides a text cursor, text selection, edit modes etc. Advanced concepts like code completion and text hints are defined in the extension interfaces. An KTextEditor implementation does not need to support all the extensions. To implement the interfaces multiple inheritance is used.

More information about interfaces for the view can be found in View Extension Interfaces.

enum KTextEditor::View::EditMode

Possible edit modes.

These correspond to various modes the text editor might be in.

Enumerator

EditInsert

Insert mode.

Characters will be added.

EditOverwrite

Overwrite mode.

Characters will be replaced.

EditViMode

Constructor & Destructor Documentation

View::View ( QWidget * parent )

Constructor.

Create a view attached to the widget parent.

Parameters

parent parent widget

See also: Document::createView()

Definition at line 198 of file ktexteditor.cpp.

View::~View ( )

virtual

Virtual destructor.

Definition at line 203 of file ktexteditor.cpp.

Member Function Documentation

virtual bool KTextEditor::View::blockSelection ( ) const

pure virtual

Get the status of the selection mode.

true indicates that block selection mode is on. If this is true, selections applied via the SelectionInterface are handled as block selections and the Copy&Paste functions work on rectangular blocks of text rather than normal.

Returns: true, if block selection mode is enabled, otherwise false

See also: setBlockSelection()

virtual QMenu* KTextEditor::View::contextMenu ( ) const

pure virtual

Get the context menu for this view.

The return value can be NULL if no context menu object was set and kxmlgui is not initialized yet. If there is no user set menu, the kxmlgui menu is returned. Do not delete this menu, if if it is the xmlgui menu.

Returns: context menu object

See also: setContextMenu()

void KTextEditor::View::contextMenuAboutToShow	(	KTextEditor::View *	view,
		QMenu *	menu
	)

signal

Signal which is emitted immediately prior to showing the current context menu.

virtual Cursor KTextEditor::View::cursorPosition ( ) const

pure virtual

Get the view's current cursor position.

A TAB character is handeled as only one character.

Returns: current cursor position

See also: setCursorPosition()

void KTextEditor::View::cursorPositionChanged	(	KTextEditor::View *	view,
		const KTextEditor::Cursor &	newPosition
	)

signal

This signal is emitted whenever the view's cursor position changed.

Parameters

view	view which emitted the signal
newPosition	new position of the cursor (Kate will pass the real cursor potition, not the virtual)

See also: cursorPosition(), cursorPositionVirtual()

virtual QPoint KTextEditor::View::cursorPositionCoordinates ( ) const

pure virtual

Get the coordinates (x/y) of the cursor position in pixels.

The returned coordinates are relative to the View. If global screen coordinates are required, e.g. for showing a QToolTip, conversion as follows is required:

QPoint viewCoordinates = view->cursorPositionCoordinates();

QPoint globalCoorinates = view->mapToGlobal(viewCoordinates);

Returns: cursor screen coordinates

virtual Cursor KTextEditor::View::cursorPositionVirtual ( ) const

pure virtual

Get the current virtual cursor position, virtual means the tabulator character (TAB) counts multiple characters, as configured by the user (e.g.

one TAB is 8 spaces). The virtual cursor position provides access to the user visible values of the current cursor position.

Returns: virtual cursor position

See also: cursorPosition()

virtual QPoint KTextEditor::View::cursorToCoordinate ( const KTextEditor::Cursor & cursor ) const

pure virtual

Get the screen coordinates (x, y) of the supplied cursor relative to the view widget in pixels.

Thus, 0,0 represents the top left hand of the view widget.

Parameters

cursor cursor to determine coordinate for.

Returns: cursor screen coordinates relative to the view widget

virtual QMenu* KTextEditor::View::defaultContextMenu ( QMenu * menu = 0L ) const

pure virtual

Populate menu with default text editor actions.

If menu is null, a menu will be created with the view as its parent.

Note: to use this menu, you will next need to call setContextMenu(), as this does not assign the new context menu.

Warning: This contains only basic options from the editor component (katepart). Plugins are not merged/integrated into it! If you want to be a better citizen and take full advantage of KTextEditor plugins do something like:
KXMLGUIClient* client = view;

// search parent XmlGuiClient

while (client->parentClient()) {

client = client->parentClient();

}

if (client->factory()) {

QList<QWidget*> conts = client->factory()->containers("menu");

foreach (QWidget *w, conts) {

if (w->objectName() == "ktexteditor_popup") {

// do something with the menu (ie adding an onshow handler)

break;

}

}

}; or simply use the aboutToShow, aboutToHide signals !!!!!

Parameters

menu	the menu to be populated, or null to create a new menu.

Returns: the menu, whether created or passed initially

virtual Document* KTextEditor::View::document ( ) const

pure virtual

Get the view's document, that means the view is a view of the returned document.

Returns: the view's document

Note: Implementation Notes: An implementation is not forced to support this, and should always return false if it does not have support.

Parameters

enable if true, try to enable mouse tracking, otherwise disable it.

Returns: the current state of mouse tracking

See also: mouseTrackingEnabled(), mousePositionChanged()

virtual bool KTextEditor::View::setSelection ( const Range & range )

pure virtual

bool View::setSelection	(	const Cursor &	position,
		int	length,
		bool	wrap = `true`
	)

virtual

This is an overloaded member function, provided for convenience, it differs from the above function only in what argument(s) it accepts.

An existing old selection will be discarded. If possible you should reimplement the default implementation with a more efficient one.

Parameters

position	start or end position of the selection, depending on the `length` parameter
length	if >0 `position` defines the start of the selection, if <0 `position` specifies the end
wrap	if false the selection does not wrap lines and reaches only to start/end of the cursors line. Default: true. Warning: true was never implemented in KDE 4.

See also: selectionRange(), selection()

Todo:: remove in KDE5 in favour of Range based setSelection()
