104 \brief The QPlainTextDocumentLayout class implements a plain text layout for QTextDocument-
105-
106 \ingroup richtext-processing-
107 \inmodule QtWidgets-
108-
109 A QPlainTextDocumentLayout is required for text documents that can-
110 be display or edited in a QPlainTextEdit. See-
111 QTextDocument::setDocumentLayout().-
112-
113 QPlainTextDocumentLayout uses the QAbstractTextDocumentLayout API-
114 that QTextDocument requires, but redefines it partially in order to-
115 support plain text better. For instances, it does not operate on-
116 vertical pixels, but on paragraphs (called blocks) instead. The-
117 height of a document is identical to the number of paragraphs it-
118 contains. The layout also doesn't support tables or nested frames,-
119 or any sort of advanced text layout that goes beyond a list of-
120 paragraphs with syntax highlighting.-

1028 \class QPlainTextEdit-
1029 \since 4.4-
1030 \brief The QPlainTextEdit class provides a widget that is used to edit and display-
1031 plain text.-
1032-
1033 \ingroup richtext-processing-
1034 \inmodule QtWidgets-
1035-
1036 \tableofcontents-
1037-
1038 \section1 Introduction and Concepts-
1039-
1040 QPlainTextEdit is an advanced viewer/editor supporting plain-
1041 text. It is optimized to handle large documents and to respond-
1042 quickly to user input.-
1043-
1044 QPlainText uses very much the same technology and concepts as-
1045 QTextEdit, but is optimized for plain text handling.-
1046-
1047 QPlainTextEdit works on paragraphs and characters. A paragraph is-
1048 a formatted string which is word-wrapped to fit into the width of-
1049 the widget. By default when reading plain text, one newline-
1050 signifies a paragraph. A document consists of zero or more-
1051 paragraphs. Paragraphs are separated by hard line breaks. Each-
1052 character within a paragraph has its own attributes, for example,-
1053 font and color.-
1054-
1055 The shape of the mouse cursor on a QPlainTextEdit is-
1056 Qt::IBeamCursor by default. It can be changed through the-
1057 viewport()'s cursor property.-
1058-
1059 \section1 Using QPlainTextEdit as a Display Widget-
1060-
1061 The text is set or replaced using setPlainText() which deletes the-
1062 existing text and replaces it with the text passed to setPlainText().-
1063-
1064 Text can be inserted using the QTextCursor class or using the-
1065 convenience functions insertPlainText(), appendPlainText() or-
1066 paste().-
1067-
1068 By default, the text edit wraps words at whitespace to fit within-
1069 the text edit widget. The setLineWrapMode() function is used to-
1070 specify the kind of line wrap you want, \l WidgetWidth or \l-
1071 NoWrap if you don't want any wrapping. If you use word wrap to-
1072 the widget's width \l WidgetWidth, you can specify whether to-
1073 break on whitespace or anywhere with setWordWrapMode().-
1074-
1075 The find() function can be used to find and select a given string-
1076 within the text.-
1077-
1078 If you want to limit the total number of paragraphs in a-
1079 QPlainTextEdit, as it is for example useful in a log viewer, then-
1080 you can use the maximumBlockCount property. The combination of-
1081 setMaximumBlockCount() and appendPlainText() turns QPlainTextEdit-
1082 into an efficient viewer for log text. The scrolling can be-
1083 reduced with the centerOnScroll() property, making the log viewer-
1084 even faster. Text can be formatted in a limited way, either using-
1085 a syntax highlighter (see below), or by appending html-formatted-
1086 text with appendHtml(). While QPlainTextEdit does not support-
1087 complex rich text rendering with tables and floats, it does-
1088 support limited paragraph-based formatting that you may need in a-
1089 log viewer.-
1090-
1091 \section2 Read-only Key Bindings-
1092-
1093 When QPlainTextEdit is used read-only the key bindings are limited to-
1094 navigation, and text may only be selected with the mouse:-
1095 \table-
1096 \header \li Keypresses \li Action-
1097 \row \li Qt::UpArrow \li Moves one line up.-
1098 \row \li Qt::DownArrow \li Moves one line down.-
1099 \row \li Qt::LeftArrow \li Moves one character to the left.-
1100 \row \li Qt::RightArrow \li Moves one character to the right.-
1101 \row \li PageUp \li Moves one (viewport) page up.-
1102 \row \li PageDown \li Moves one (viewport) page down.-
1103 \row \li Home \li Moves to the beginning of the text.-
1104 \row \li End \li Moves to the end of the text.-
1105 \row \li Alt+Wheel-
1106 \li Scrolls the page horizontally (the Wheel is the mouse wheel).-
1107 \row \li Ctrl+Wheel \li Zooms the text.-
1108 \row \li Ctrl+A \li Selects all text.-
1109 \endtable-
1110-
1111-
1112 \section1 Using QPlainTextEdit as an Editor-
1113-
1114 All the information about using QPlainTextEdit as a display widget also-
1115 applies here.-
1116-
1117 Selection of text is handled by the QTextCursor class, which provides-
1118 functionality for creating selections, retrieving the text contents or-
1119 deleting selections. You can retrieve the object that corresponds with-
1120 the user-visible cursor using the textCursor() method. If you want to set-
1121 a selection in QPlainTextEdit just create one on a QTextCursor object and-
1122 then make that cursor the visible cursor using setCursor(). The selection-
1123 can be copied to the clipboard with copy(), or cut to the clipboard with-
1124 cut(). The entire text can be selected using selectAll().-
1125-
1126 QPlainTextEdit holds a QTextDocument object which can be retrieved using the-
1127 document() method. You can also set your own document object using setDocument().-
1128 QTextDocument emits a textChanged() signal if the text changes and it also-
1129 provides a isModified() function which will return true if the text has been-
1130 modified since it was either loaded or since the last call to setModified-
1131 with false as argument. In addition it provides methods for undo and redo.-
1132-
1133 \section2 Syntax Highlighting-
1134-
1135 Just like QTextEdit, QPlainTextEdit works together with-
1136 QSyntaxHighlighter.-
1137-
1138 \section2 Editing Key Bindings-
1139-
1140 The list of key bindings which are implemented for editing:-
1141 \table-
1142 \header \li Keypresses \li Action-
1143 \row \li Backspace \li Deletes the character to the left of the cursor.-
1144 \row \li Delete \li Deletes the character to the right of the cursor.-
1145 \row \li Ctrl+C \li Copy the selected text to the clipboard.-
1146 \row \li Ctrl+Insert \li Copy the selected text to the clipboard.-
1147 \row \li Ctrl+K \li Deletes to the end of the line.-
1148 \row \li Ctrl+V \li Pastes the clipboard text into text edit.-
1149 \row \li Shift+Insert \li Pastes the clipboard text into text edit.-
1150 \row \li Ctrl+X \li Deletes the selected text and copies it to the clipboard.-
1151 \row \li Shift+Delete \li Deletes the selected text and copies it to the clipboard.-
1152 \row \li Ctrl+Z \li Undoes the last operation.-
1153 \row \li Ctrl+Y \li Redoes the last operation.-
1154 \row \li LeftArrow \li Moves the cursor one character to the left.-
1155 \row \li Ctrl+LeftArrow \li Moves the cursor one word to the left.-
1156 \row \li RightArrow \li Moves the cursor one character to the right.-
1157 \row \li Ctrl+RightArrow \li Moves the cursor one word to the right.-
1158 \row \li UpArrow \li Moves the cursor one line up.-
1159 \row \li Ctrl+UpArrow \li Moves the cursor one word up.-
1160 \row \li DownArrow \li Moves the cursor one line down.-
1161 \row \li Ctrl+Down Arrow \li Moves the cursor one word down.-
1162 \row \li PageUp \li Moves the cursor one page up.-
1163 \row \li PageDown \li Moves the cursor one page down.-
1164 \row \li Home \li Moves the cursor to the beginning of the line.-
1165 \row \li Ctrl+Home \li Moves the cursor to the beginning of the text.-
1166 \row \li End \li Moves the cursor to the end of the line.-
1167 \row \li Ctrl+End \li Moves the cursor to the end of the text.-
1168 \row \li Alt+Wheel \li Scrolls the page horizontally (the Wheel is the mouse wheel).-
1169 \row \li Ctrl+Wheel \li Zooms the text.-
1170 \endtable-
1171-
1172 To select (mark) text hold down the Shift key whilst pressing one-
1173 of the movement keystrokes, for example, \e{Shift+Right Arrow}-
1174 will select the character to the right, and \e{Shift+Ctrl+Right-
1175 Arrow} will select the word to the right, etc.-
1176-
1177 \section1 Differences to QTextEdit-
1178-
1179 QPlainTextEdit is a thin class, implemented by using most of the-
1180 technology that is behind QTextEdit and QTextDocument. Its-
1181 performance benefits over QTextEdit stem mostly from using a-
1182 different and simplified text layout called-
1183 QPlainTextDocumentLayout on the text document (see-
1184 QTextDocument::setDocumentLayout()). The plain text document layout-
1185 does not support tables nor embedded frames, and \e{replaces a-
1186 pixel-exact height calculation with a line-by-line respectively-
1187 paragraph-by-paragraph scrolling approach}. This makes it possible-
1188 to handle significantly larger documents, and still resize the-
1189 editor with line wrap enabled in real time. It also makes for a-
1190 fast log viewer (see setMaximumBlockCount()).-
