59 \class QAbstractTextDocumentLayout -

60 \reentrant -

61 -

62 \brief The QAbstractTextDocumentLayout class is an abstract base -

63 class used to implement custom layouts for QTextDocuments. -

64 \inmodule QtGui -

65 -

66 \ingroup richtext-processing -

67 -

68 The standard layout provided by Qt can handle simple word processing -

69 including inline images, lists and tables. -

70 -

71 Some applications, e.g., a word processor or a DTP application might need -

72 more features than the ones provided by Qt's layout engine, in which case -

73 you can subclass QAbstractTextDocumentLayout to provide custom layout -

74 behavior for your text documents. -

75 -

76 An instance of the QAbstractTextDocumentLayout subclass can be installed -

77 on a QTextDocument object with the -

78 \l{QTextDocument::}{setDocumentLayout()} function. -

79 -

80 You can insert custom objects into a QTextDocument; see the -

81 QTextObjectInterface class description for details. -

87 \class QTextObjectInterface -

88 \brief The QTextObjectInterface class allows drawing of -

89 custom text objects in \l{QTextDocument}s. -

90 \since 4.5 -

91 \inmodule QtGui -

92 -

93 A text object describes the structure of one or more elements in a -

94 text document; for instance, images imported from HTML are -

95 implemented using text objects. A text object knows how to lay out -

96 and draw its elements when a document is being rendered. -

97 -

98 Qt allows custom text objects to be inserted into a document by -

99 registering a custom \l{QTextCharFormat::objectType()}{object -

100 type} with QTextCharFormat. A QTextObjectInterface must also be -

101 implemented for this type and be -

102 \l{QAbstractTextDocumentLayout::registerHandler()}{registered} -

103 with the QAbstractTextDocumentLayout of the document. When the -

104 object type is encountered while rendering a QTextDocument, the -

105 intrinsicSize() and drawObject() functions of the interface are -

106 called. -

107 -

108 The following list explains the required steps of inserting a -

109 custom text object into a document: -

110 -

111 \list -

112 \li Choose an \a objectType. The \a objectType is an integer with a -

113 value greater or equal to QTextFormat::UserObject. -

114 \li Create a QTextCharFormat object and set the object type to the -

115 chosen type using the setObjectType() function. -

116 \li Implement the QTextObjectInterface class. -

117 \li Call QAbstractTextDocumentLayout::registerHandler() with an instance of your -

118 QTextObjectInterface subclass to register your object type. -

119 \li Insert QChar::ObjectReplacementCharacter with the aforementioned -

120 QTextCharFormat of the chosen object type into the document. -

121 As mentioned, the functions of QTextObjectInterface -

122 \l{QTextObjectInterface::}{intrinsicSize()} and -

123 \l{QTextObjectInterface::}{drawObject()} will then be called with the -

124 QTextFormat as parameter whenever the replacement character is -

125 encountered. -

126 \endlist -

127 -

128 A class implementing a text object needs to inherit both QObject -

129 and QTextObjectInterface. QObject must be the first class -

130 inherited. For instance: -

131 -

132 \snippet qtextobject/textobjectinterface.h 0 -

133 -

134 The data of a text object is usually stored in the QTextCharFormat -

135 using QTextCharFormat::setProperty(), and then retrieved with -

136 QTextCharFormat::property(). -

137 -

138 \warning Copy and Paste operations ignore custom text objects. -

150 \fn virtual QSizeF QTextObjectInterface::intrinsicSize(QTextDocument *doc, int posInDocument, const QTextFormat &format) = 0 -

151 -

152 The intrinsicSize() function returns the size of the text object -

153 represented by \a format in the given document (\a doc) at the -

154 given position (\a posInDocument). -

155 -

156 The size calculated will be used for subsequent calls to -

167 The size of the rectangle, \a rect, to draw in is the size -

168 previously calculated by intrinsicSize(). The rectangles position -

169 is relative to the \a painter. -

253 */ -

254 -

255 /*! -

256 \fn void QAbstractTextDocumentLayout::documentChanged(int position, int charsRemoved, int charsAdded) -

257 -

258 This function is called whenever the contents of the document change. A -

259 change occurs when text is inserted, removed, or a combination of these -

260 two. The change is specified by \a position, \a charsRemoved, and -

261 \a charsAdded corresponding to the starting character position of the -

262 change, the number of characters removed from the document, and the -

263 number of characters added. -

264 -

265 For example, when inserting the text "Hello" into an empty document, -

266 \a charsRemoved would be 0 and \a charsAdded would be 5 (the length of -

267 the string). -

268 -

269 Replacing text is a combination of removing and inserting. For example, if -

270 the text "Hello" gets replaced by "Hi", \a charsRemoved would be 5 and -

271 \a charsAdded would be 2. -

272 -

273 For subclasses of QAbstractTextDocumentLayout, this is the central function -

274 where a large portion of the work to lay out and position document contents -

275 is done. -

276 -

277 For example, in a subclass that only arranges blocks of text, an -

278 implementation of this function would have to do the following: -

279 -

280 \list -

281 \li Determine the list of changed \l{QTextBlock}(s) using the parameters -

282 provided. -

283 \li Each QTextBlock object's corresponding QTextLayout object needs to -

284 be processed. You can access the \l{QTextBlock}'s layout using the -

285 QTextBlock::layout() function. This processing should take the -

286 document's page size into consideration. -

287 \li If the total number of pages changed, the pageCountChanged() signal -

288 should be emitted. -

289 \li If the total size changed, the documentSizeChanged() signal should -

290 be emitted. -

291 \li The update() signal should be emitted to schedule a repaint of areas -

292 in the layout that require repainting. -
