The QStyle class is an abstract base class that encapsulates the look and feel of a GUI.

The QStylePainter class is a convenience class for drawing QStyle elements inside a widget.

Qt contains a set of QStyle subclasses that emulate the styles of the different platforms supported by Qt (QWindowsStyle, QMacStyle, QMotifStyle, etc.). By default, these styles are built into the QtGui library. Styles can also be made available as plugins.

Qt's built-in widgets use QStyle to perform nearly all of their drawing, ensuring that they look exactly like the equivalent native widgets. The diagram below shows a QComboBox in eight different styles.

Topics:

Setting a Style

The style of the entire application can be set using the QApplication::setStyle() function. It can also be specified by the user of the application, using the -style command-line option:

./myapplication -style motif

If no style is specified, Qt will choose the most appropriate style for the user's platform or desktop environment.

A style can also be set on an individual widget using the QWidget::setStyle() function.

Developing Style-Aware Custom Widgets

If you are developing custom widgets and want them to look good on all platforms, you can use QStyle functions to perform parts of the widget drawing, such as drawItemText(), drawItemPixmap(), drawPrimitive(), drawControl(), and drawComplexControl().

Most QStyle draw functions take four arguments:

an enum value specifying which graphical element to draw

a QStyleOption specifying how and where to render that element

a QPainter that should be used to draw the element

a QWidget on which the drawing is performed (optional)

For example, if you want to draw a focus rectangle on your widget, you can write:

void MyWidget::paintEvent(QPaintEvent * /* event

QStylePainter extends QPainter with a set of high-level draw...() functions implemented on top of QStyle's API. The advantage of using QStylePainter is that the parameter lists get considerably shorter. Whereas a QStyle object must be able to draw on any widget using any painter (because the application normally has one QStyle object shared by all widget), a QStylePainter is initialized with a widget, eliminating the need to specify the QWidget, the QPainter, and the QStyle for every function call.

Example using QStyle directly:

void MyWidget::paintEvent(QPaintEvent * /* event

</para> *<para> QLinearGradient QtGui.backgroundGradient	(	topLeft	,
		bottomRight
	)

multiline comments.To deal with these cases it is necessary to know the end state of the previous text QtGui.block

(

e.g."in comment "

)

The QSyntaxHighlighter class allows you to define syntax highlighting rules, and in addition you can use the class to query a document's current formatting or user data.

The QSyntaxHighlighter class is a base class for implementing QTextEdit syntax highlighters. A syntax highligher automatically highlights parts of the text in a QTextEdit, or more generally in a QTextDocument. Syntax highlighters are often used when the user is entering text in a specific format (for example source code) and help the user to read the text and identify syntax errors.

To provide your own syntax highlighting, you must subclass QSyntaxHighlighter and reimplement highlightBlock().

When you create an instance of your QSyntaxHighlighter subclass, pass it the QTextEdit or QTextDocument that you want the syntax highlighting to be applied to. For example:

QTextEdit editor = new QTextEdit;

MyHighlighter *highlighter = new MyHighlighter(editor->document());

After this your highlightBlock() function will be called automatically whenever necessary. Use your highlightBlock() function to apply formatting (e.g. setting the font and color) to the text that is passed to it. QSyntaxHighlighter provides the setFormat() function which applies a given QTextCharFormat on the current text block. For example:

void MyHighlighter::highlightBlock(const QString &text)

{

QTextCharFormat myClassFormat;

myClassFormat.setFontWeight(QFont::Bold);

myClassFormat.setForeground(Qt::darkMagenta);

QString pattern = "\\bMy[A-Za-z]+\\b";

QRegExp expression(pattern);

int index = text.indexOf(expression);

while (index >= 0) {

int length = expression.matchedLength();

setFormat(index, length, myClassFormat);

index = text.indexOf(expression, index + length);

}

}

Some syntaxes can have constructs that span several text blocks. For example, a C++ syntax highlighter should be able to cope with /...

Highlights the given text block. This function is called when necessary by the rich text engine, i.e. on text blocks which have changed.

To provide your own syntax highlighting, you must subclass QSyntaxHighlighter and reimplement highlightBlock(). In your reimplementation you should parse the block's text and call setFormat() as often as necessary to apply any font and color changes that you require. For example:

void MyHighlighter::highlightBlock(const QString &text)

{

QTextCharFormat myClassFormat;

myClassFormat.setFontWeight(QFont::Bold);

myClassFormat.setForeground(Qt::darkMagenta);

QString pattern = "\\bMy[A-Za-z]+\\b";

QRegExp expression(pattern);

int index = text.indexOf(expression);

while (index >= 0) {

int length = expression.matchedLength();

setFormat(index, length, myClassFormat);

index = text.indexOf(expression, index + length);

}

}

Some syntaxes can have constructs that span several text blocks. For example, a C++ syntax highlighter should be able to cope with /*...

This function is applied to the syntax highlighter's current text block (i.e. the text that is passed to the highlightBlock() function).

The specified format is applied to the text from the start position for a length of count characters (if count is 0, nothing is done). The formatting properties set in format are merged at display time with the formatting information stored directly in the document, for example as previously set with QTextCursor's functions. Note that the document itself remains unmodified by the format set through this function.

This is an overloaded function.

The specified color is applied to the current text block from the start position for a length of count characters.
