Detailed Description

An model for providing line annotation information.

Introduction

AnnotationModel is a model-like interface that can be implemented to provide annotation information for each line in a document. It provides means to retrieve several kinds of data for a given line in the document.

Implementing a AnnotationModel

The public interface of this class is loosely based on the QAbstractItemModel interfaces. It only has a single method to override which is the data() method to provide the actual data for a line and role combination.

Since

4.1

Member Function Documentation

data()

virtual QVariant KTextEditor::AnnotationModel::data ( int line, Qt::ItemDataRole role ) const

pure virtual

data() is used to retrieve the information needed to present the annotation information from the annotation model.

The provider should return useful information for the line and the data role.

The following roles are supported:

• Qt::DisplayRole - a short display text to be placed in the border
• Qt::TooltipRole - a tooltip information, longer text possible
• Qt::BackgroundRole - a brush to be used to paint the background on the border
• Qt::ForegroundRole - a brush to be used to paint the text on the border
• AnnotationModel::GroupIdentifierRole - a string which identifies a group of items which will be highlighted on mouseover; return the same string for all items in a group (KDevelop uses a VCS revision number, for example)

Parameters

line	the line for which the data is to be retrieved
role	the role to identify which kind of annotation is to be retrieved

Returns

a QVariant that contains the data for the given role.

lineChanged

void KTextEditor::AnnotationModel::lineChanged ( int line )

signal

The model should emit the signal lineChanged() when a line has to be updated.

Note

Kate Part implementation details: lineChanged() repaints the whole annotation border automatically.

reset

void KTextEditor::AnnotationModel::reset ( )

signal

The model should emit the signal reset() when the text of almost all lines changes.

In most cases it is enough to call lineChanged().

Note

Kate Part implementation details: Whenever reset() is emitted Kate Part iterates over all lines of the document. Kate Part searches for the longest text to determine the annotation border's width.
