Detailed Description

Pixel coordinate to Cursor extension interface for the View.

Introduction

The CoordinatesToCursorInterface makes it possible to map a pixel coordinate to a cursor position. To map a cursor position to pixel coordinates use one of

• KTextEditor::View::cursorToCoordinate()
• KTextEditor::View::cursorPositionCoordinates()

Accessing the CoordinatesToCursorInterface

The CoordinatesToCursorInterface is an extension interface for a View, i.e. the View inherits the interface provided that the used KTextEditor library implements the interface. Use qobject_cast to access the interface:

// view is of type KTextEditor::View*
KTextEditor::CoordinatesToCursorInterface *iface =
    qobject_cast<KTextEditor::CoordinatesToCursorInterface*>( view );

if( iface ) {
    // the implementation supports the interface
    // do stuff
}

Note

KDE5: merge into KTextEditor::View (or name it ViewportInterface and add accessors to the QScrollBars and convenience functions like cursorToCoordinate(), scollLines(int count), etc.

Member Function Documentation

virtual KTextEditor::Cursor KTextEditor::CoordinatesToCursorInterface::coordinatesToCursor ( const QPoint &  coord ) const

pure virtual

Get the text-cursor in the document from the screen coordinates, relative to the view widget.

To map a cursor to pixel coordinates (the reverse transformation) use KTextEditor::View::cursorToCoordinate().

Parameters

coord

coordinates relative to the view widget

Returns

cursor in the View, that points onto the character under the given coordinate. May be KTextEditor::Cursor::invalid().
