Constructor & Destructor Documentation

QTextEdit::QTextEdit ( const QString & text,

const QString & context = QString::null,

QWidget * parent = 0,

const char * name = 0

)

Constructs a QTextEdit with parent parent and name name. The text edit will display the text text using context context.
The context is a path which the text edit's QMimeSourceFactory uses to resolve the locations of files and images. It is passed to the mimeSourceFactory() when quering data.
For example if the text contains an image tag, {

}, and the context is "path/to/look/in", the QMimeSourceFactory will try to load the image from "path/to/look/in/image.png". If the tag was {

}, the context will not be used (because QMimeSourceFactory recognizes that we have used an absolute path) and will try to load "/image.png". The context is applied in exactly the same way to hrefs, for example, {Target}, would resolve to "path/to/look/in/target.html".

bool QTextEdit::find ( const QString & expr,

bool cs,

bool wo,

bool forward = TRUE,

int * para = 0,

int * index = 0

) [virtual]

Finds the next occurrence of the string, expr. Returns TRUE if expr is found; otherwise returns FALSE.
If para and index are both null the search begins from the current cursor position. If para and index are both not null, the search begins from the *index character position in the *para paragraph.
If cs is TRUE the search is case sensitive, otherwise it is case insensitive. If wo is TRUE the search looks for whole word matches only; otherwise it searches for any matching text. If forward is TRUE (the default) the search works forward from the starting position to the end of the text, otherwise it works backwards to the beginning of the text.
If expr is found the function returns TRUE. If index and para are not null, the number of the paragraph in which the first character of the match was found is put into *para, and the index position of that character within the paragraph is put into *index.
If expr is not found the function returns FALSE. If index and para are not null and expr is not found, *index and *para are undefined.

For internal use only.

This function sets the QTextDocument which should be used by the text edit to doc. This can be used, for example, if you want to display a document using multiple views. You would create a QTextDocument and set it to the text edits which should display it. You would need to connect to the textChanged() and selectionChanged() signals of all the text edits and update them all accordingly (preferably with a slight delay for efficiency reasons).

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Changes the text of the text edit to the string text and the context to context. Any previous text is removed.
text may be interpreted either as plain text or as rich text, depending on the textFormat(). The default setting is AutoText, i.e. the text edit autodetects the format from text.
The optional context is a path which the text edit's QMimeSourceFactory uses to resolve the locations of files and images. (See {QTextEdit::QTextEdit()}.) It is passed to the text edit's QMimeSourceFactory when quering data.
Note that the undo/redo history is cleared by this function.

For internal use only.

QTextEdit is optimized for large amounts text. One of its optimizations is to format only the visible text, formatting the rest on demand, e.g. as the user scrolls, so you don't usually need to call this function.
In some situations you may want to force the whole text to be formatted. For example, if after calling setText(), you wanted to know the height of the document (using contentsHeight()), you would call this function first.

Property Documentation

QString QTextEdit::documentTitle [read]

the title of the document parsed from the text.
For PlainText the title will be an empty string. For RichText the title will be the text between the {<title>} tags, if present, otherwise an empty string.
Definition at line 81 of file qtextedit.h.

bool QTextEdit::hasSelectedText [read]

whether some text is selected in selection 0

Definition at line 86 of file qtextedit.h.

int QTextEdit::length [read]

the number of characters in the text

Definition at line 82 of file qtextedit.h.

bool QTextEdit::linkUnderline [read, write]

whether hypertext links will be underlined
If TRUE (the default) hypertext links will be displayed underlined. If FALSE links will not be displayed underlined.
Definition at line 80 of file qtextedit.h.

bool Qt3::QTextEdit::modified [read, write]

whether the document has been modified by the user

Definition at line 90 of file qtextedit.h.
Referenced by init(), isModified(), and setModified().

QTextEdit::overwriteMode [read, write]

the text edit's overwrite mode
If FALSE (the default) characters entered by the user are inserted with any characters to the right being moved out of the way. If TRUE, the editor is in overwrite mode, i.e. characters entered by the user overwrite any characters to the right of the cursor position.
Definition at line 89 of file qtextedit.h.

QBrush QTextEdit::paper [read, write]

the background (paper) brush.
The brush that is currently used to draw the background of the text edit. The initial setting is an empty brush.
Definition at line 79 of file qtextedit.h.

bool Qt3::QTextEdit::readOnly [read, write]

whether the text edit is read-only
In a read-only text edit the user can only navigate through the text and select text; modifying the text is not possible.
This property's default is FALSE.
Definition at line 91 of file qtextedit.h.

QString QTextEdit::selectedText [read]

The selected text (from selection 0) or an empty string if there is no currently selected text (in selection 0).
The text is always returned as PlainText regardless of the text format. In a future version of Qt an HTML subset may be returned depending on the text format.

hasSelectedText

Definition at line 87 of file qtextedit.h.

int QTextEdit::tabStopWidth [read, write]

the tab stop width in pixels

Definition at line 93 of file qtextedit.h.

QTextEdit::text [read, write]

the text edit's text
There is no default text.
On setting, any previous text is deleted.
The text may be interpreted either as plain text or as rich text, depending on the textFormat(). The default setting is AutoText, i.e. the text edit autodetects the format of the text.
For richtext, calling text() on an editable QTextEdit will cause the text to be regenerated from the textedit. This may mean that the QString returned may not be exactly the same as the one that was set.

textFormat

Definition at line 78 of file qtextedit.h.

Qt::TextFormat QTextEdit::textFormat [read, write]

the text format: rich text, plain text or auto text
The text format is one of the following: PlainText - all characters, except newlines, are displayed verbatim, including spaces. Whenever a newline appears in the text the text edit inserts a hard line break and begins a new paragraph. RichText - rich text rendering. The available styles are defined in the default stylesheet QStyleSheet::defaultSheet(). AutoText - this is the default. The text edit autodetects which rendering style is best, PlainText or RichText. This is done by using the QStyleSheet::mightBeRichText() function.
Definition at line 75 of file qtextedit.h.

int QTextEdit::undoDepth [read, write]

the depth of the undo history
The maximum number of steps in the undo/redo history. The default is 100.

See also:
undo() redo()

Definition at line 88 of file qtextedit.h.

QTextEdit::undoRedoEnabled [read, write]

whether undo/redo is enabled
The default is TRUE.
Definition at line 92 of file qtextedit.h.

QTextEdit::WordWrap QTextEdit::wordWrap [read, write]

the word wrap mode
The default mode is WidgetWidth which causes words to be wrapped at the right edge of the text edit. Wrapping occurs at whitespace, keeping whole words intact. If you want wrapping to occur within words use setWrapPolicy(). If you set a wrap mode of FixedPixelWidth or FixedColumnWidth you should also call setWrapColumnOrWidth() with the width you want.

See also:
WordWrap, wrapColumnOrWidth, wrapPolicy,

Definition at line 83 of file qtextedit.h.

int QTextEdit::wrapColumnOrWidth [read, write]

the position (in pixels or columns depending on the wrap mode) where text will be wrapped
If the wrap mode is FixedPixelWidth, the value is the number of pixels from the left edge of the text edit at which text should be wrapped. If the wrap mode is FixedColumnWidth, the value is the column number (in character columns) from the left edge of the text edit at which text should be wrapped.

See also:
wordWrap

Definition at line 84 of file qtextedit.h.

QTextEdit::WrapPolicy QTextEdit::wrapPolicy [read, write]

the word wrap policy, at whitespace or anywhere
Defines where text can be wrapped when word wrap mode is not NoWrap. The choices are AtWhiteSpace (the default) and Anywhere.
