112 \brief The QPlainTextDocumentLayout class implements a plain text layout for QTextDocument -
113 -
114 \ingroup richtext-processing -
115 \inmodule QtWidgets -
116 -
117 A QPlainTextDocumentLayout is required for text documents that can -
118 be display or edited in a QPlainTextEdit. See -
119 QTextDocument::setDocumentLayout(). -
120 -
121 QPlainTextDocumentLayout uses the QAbstractTextDocumentLayout API -
122 that QTextDocument requires, but redefines it partially in order to -
123 support plain text better. For instances, it does not operate on -
124 vertical pixels, but on paragraphs (called blocks) instead. The -
125 height of a document is identical to the number of paragraphs it -
126 contains. The layout also doesn't support tables or nested frames, -
127 or any sort of advanced text layout that goes beyond a list of -
128 paragraphs with syntax highlighting. -

1027 \class QPlainTextEdit -
1028 \since 4.4 -
1029 \brief The QPlainTextEdit class provides a widget that is used to edit and display -
1030 plain text. -
1031 -
1032 \ingroup richtext-processing -
1033 \inmodule QtWidgets -
1034 -
1035 \tableofcontents -
1036 -
1037 \section1 Introduction and Concepts -
1038 -
1039 QPlainTextEdit is an advanced viewer/editor supporting plain -
1040 text. It is optimized to handle large documents and to respond -
1041 quickly to user input. -
1042 -
1043 QPlainText uses very much the same technology and concepts as -
1044 QTextEdit, but is optimized for plain text handling. -
1045 -
1046 QPlainTextEdit works on paragraphs and characters. A paragraph is -
1047 a formatted string which is word-wrapped to fit into the width of -
1048 the widget. By default when reading plain text, one newline -
1049 signifies a paragraph. A document consists of zero or more -
1050 paragraphs. Paragraphs are separated by hard line breaks. Each -
1051 character within a paragraph has its own attributes, for example, -
1052 font and color. -
1053 -
1054 The shape of the mouse cursor on a QPlainTextEdit is -
1055 Qt::IBeamCursor by default. It can be changed through the -
1056 viewport()'s cursor property. -
1057 -
1058 \section1 Using QPlainTextEdit as a Display Widget -
1059 -
1060 The text is set or replaced using setPlainText() which deletes the -
1061 existing text and replaces it with the text passed to setPlainText(). -
1062 -
1063 Text can be inserted using the QTextCursor class or using the -
1064 convenience functions insertPlainText(), appendPlainText() or -
1065 paste(). -
1066 -
1067 By default, the text edit wraps words at whitespace to fit within -
1068 the text edit widget. The setLineWrapMode() function is used to -
1069 specify the kind of line wrap you want, \l WidgetWidth or \l -
1070 NoWrap if you don't want any wrapping. If you use word wrap to -
1071 the widget's width \l WidgetWidth, you can specify whether to -
1072 break on whitespace or anywhere with setWordWrapMode(). -
1073 -
1074 The find() function can be used to find and select a given string -
1075 within the text. -
1076 -
1077 If you want to limit the total number of paragraphs in a -
1078 QPlainTextEdit, as it is for example useful in a log viewer, then -
1079 you can use the maximumBlockCount property. The combination of -
1080 setMaximumBlockCount() and appendPlainText() turns QPlainTextEdit -
1081 into an efficient viewer for log text. The scrolling can be -
1082 reduced with the centerOnScroll() property, making the log viewer -
1083 even faster. Text can be formatted in a limited way, either using -
1084 a syntax highlighter (see below), or by appending html-formatted -
1085 text with appendHtml(). While QPlainTextEdit does not support -
1086 complex rich text rendering with tables and floats, it does -
1087 support limited paragraph-based formatting that you may need in a -
1088 log viewer. -
1089 -
1090 \section2 Read-only Key Bindings -
1091 -
1092 When QPlainTextEdit is used read-only the key bindings are limited to -
1093 navigation, and text may only be selected with the mouse: -
1094 \table -
1095 \header \li Keypresses \li Action -
1096 \row \li Qt::UpArrow \li Moves one line up. -
1097 \row \li Qt::DownArrow \li Moves one line down. -
1098 \row \li Qt::LeftArrow \li Moves one character to the left. -
1099 \row \li Qt::RightArrow \li Moves one character to the right. -
1100 \row \li PageUp \li Moves one (viewport) page up. -
1101 \row \li PageDown \li Moves one (viewport) page down. -
1102 \row \li Home \li Moves to the beginning of the text. -
1103 \row \li End \li Moves to the end of the text. -
1104 \row \li Alt+Wheel -
1105 \li Scrolls the page horizontally (the Wheel is the mouse wheel). -
1106 \row \li Ctrl+Wheel \li Zooms the text. -
1107 \row \li Ctrl+A \li Selects all text. -
1108 \endtable -
1109 -
1110 -
1111 \section1 Using QPlainTextEdit as an Editor -
1112 -
1113 All the information about using QPlainTextEdit as a display widget also -
1114 applies here. -
1115 -
1116 Selection of text is handled by the QTextCursor class, which provides -
1117 functionality for creating selections, retrieving the text contents or -
1118 deleting selections. You can retrieve the object that corresponds with -
1119 the user-visible cursor using the textCursor() method. If you want to set -
1120 a selection in QPlainTextEdit just create one on a QTextCursor object and -
1121 then make that cursor the visible cursor using setCursor(). The selection -
1122 can be copied to the clipboard with copy(), or cut to the clipboard with -
1123 cut(). The entire text can be selected using selectAll(). -
1124 -
1125 QPlainTextEdit holds a QTextDocument object which can be retrieved using the -
1126 document() method. You can also set your own document object using setDocument(). -
1127 QTextDocument emits a textChanged() signal if the text changes and it also -
1128 provides a isModified() function which will return true if the text has been -
1129 modified since it was either loaded or since the last call to setModified -
1130 with false as argument. In addition it provides methods for undo and redo. -
1131 -
1132 \section2 Syntax Highlighting -
1133 -
1134 Just like QTextEdit, QPlainTextEdit works together with -
1135 QSyntaxHighlighter. -
1136 -
1137 \section2 Editing Key Bindings -
1138 -
1139 The list of key bindings which are implemented for editing: -
1140 \table -
1141 \header \li Keypresses \li Action -
1142 \row \li Backspace \li Deletes the character to the left of the cursor. -
1143 \row \li Delete \li Deletes the character to the right of the cursor. -
1144 \row \li Ctrl+C \li Copy the selected text to the clipboard. -
1145 \row \li Ctrl+Insert \li Copy the selected text to the clipboard. -
1146 \row \li Ctrl+K \li Deletes to the end of the line. -
1147 \row \li Ctrl+V \li Pastes the clipboard text into text edit. -
1148 \row \li Shift+Insert \li Pastes the clipboard text into text edit. -
1149 \row \li Ctrl+X \li Deletes the selected text and copies it to the clipboard. -

1176 \section1 Differences to QTextEdit -
1177 -
1178 QPlainTextEdit is a thin class, implemented by using most of the -
1179 technology that is behind QTextEdit and QTextDocument. Its -
1180 performance benefits over QTextEdit stem mostly from using a -
1181 different and simplified text layout called -
1182 QPlainTextDocumentLayout on the text document (see -
1183 QTextDocument::setDocumentLayout()). The plain text document layout -
1184 does not support tables nor embedded frames, and \e{replaces a -
1185 pixel-exact height calculation with a line-by-line respectively -
1186 paragraph-by-paragraph scrolling approach}. This makes it possible -
1187 to handle significantly larger documents, and still resize the -
1188 editor with line wrap enabled in real time. It also makes for a -
1189 fast log viewer (see setMaximumBlockCount()). -
