.SH DESCRIPTION
|
|
The QStyle class specifies the look and feel of a GUI.
|
|
.PP
|
|
A large number of GUI elements are common to many widgets. The QStyle class allows the look of these elements to be modified across all widgets that use the QStyle functions. It also provides two feel options: Motif and Windows.
|
|
.PP
|
|
Although it is not possible to fully enumerate the look of graphical elements and the feel of widgets in a GUI, QStyle provides a considerable amount of control and customisability.
|
|
.PP
|
|
In Qt 1.x the look and feel option for widgets was specified by a single value: the GUIStyle. Starting with Qt 2.0, this notion was expanded to allow the look to be specified by virtual drawing functions.
|
|
.PP
|
|
Derived classes may reimplement some or all of the drawing functions to modify the look of all widgets that use those functions.
|
|
.PP
|
|
Languages written from right to left (such as Arabic and Hebrew) usually also mirror the whole layout of widgets. If you design a style, you should take special care when drawing asymmetric elements to make sure that they also look correct in a mirrored layout. You can start your application with \fC-reverse\fR to check the mirrored layout. Also notice, that for a reversed layout, the light usually comes from top right instead of top left.
|
|
.PP
|
|
The actual reverse layout is performed automatically when possible. However, for the sake of flexibility, the translation cannot be performed everywhere. The documentation for each function in the QStyle API states whether the function expects/returns logical or screen coordinates. Using logical coordinates (in ComplexControls, for example) provides great flexibility in controlling the look of a widget. Use visualRect() when necessary to translate logical coordinates into screen coordinates for drawing.
|
|
.PP
|
|
In Qt versions prior to 3.0, if you wanted a low level route into changing the appearance of a widget, you would reimplement polish(). With the new 3.0 style engine the recommended approach is to reimplement the draw functions, for example drawItem(), drawPrimitive(), drawControl(), drawControlMask(), drawComplexControl() and drawComplexControlMask(). Each of these functions is called with a range of parameters that provide information that you can use to determine how to draw them, e.g. style flags, rectangle, color group, etc.
|
|
.PP
|
|
For information on changing elements of an existing style or creating your own style see the Style overview.
|
|
.PP
|
|
Styles can also be created as plugins.

This function is called for every widget at some point after it has been fully created but just \fIbefore\fR it is shown the very first time.
|
|
.PP
|
|
Reasonable actions in this function might be to call QWidget::setBackgroundMode() for the widget. An example of highly unreasonable use would be setting the geometry! Reimplementing this function gives you a back-door through which you can change the appearance of a widget. With Qt 3.0's style engine you will rarely need to write your own polish(); instead reimplement drawItem(), drawPrimitive(), etc.
|
|
.PP
|

The QWidget::inherits() function may provide enough information to allow class-specific customizations. But be careful not to hard-code things too much because new QStyle subclasses are expected to work reasonably with all current and \fIfuture\fR widgets.

The \fIwidget\fR argument is a pointer to a QWidget or one of its subclasses. The widget can be cast to the appropriate type based on the value of \fIcontents\fR. The \fIopt\fR argument can be used to pass extra information required when calculating the size. Note that \fIopt\fR may be the default value even for ContentsTypes that can make use of the extra options. See the table below for the appropriate \fIwidget\fR and \fIopt\fR usage:
