Detailed Description

The QStyleOptionProgressBarV2 class is used to describe the parameters necessary for drawing a progress bar in Qt 4.1 or above.

Since: 4.1

An instance of this class has type SO_ProgressBar and version 2.

The type is used internally by QStyleOption, its subclasses, and qstyleoption_cast() to determine the type of style option. In general you do not need to worry about this unless you want to create your own QStyleOption subclass and your own styles. The version is used by QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast(), you normally do not need to check it.

If you create your own QStyle subclass, you should handle both QStyleOptionProgressBar and QStyleOptionProgressBarV2. One way to achieve this is to use the QStyleOptionProgressBarV2 copy constructor. For example:

    if (const QStyleOptionProgressBar *progressBarOption =
           qstyleoption_cast<const QStyleOptionProgressBar *>(option)) {
        QStyleOptionProgressBarV2 progressBarV2(*progressBarOption);
        // draw the progress bar using progressBarV2
    }

In the example above: If the progressBarOption's version is 1, the extra members (orientation , invertedAppearance , and bottomToTop ) are set to default values for progressBarV2. If the progressBarOption's version is 2, the constructor will simply copy the extra members to progressBarV2.

For an example demonstrating how style options can be used, see the widgets/styles{Styles} example.

Enumerations

◆ StyleOptionType

enum QStyleOptionProgressBarV2::StyleOptionType

This enum is used to hold information about the type of the style option, and is defined for each QStyleOption subclass.

Type The type of style option provided (SO_ProgressBar for this class).

The type is used internally by QStyleOption, its subclasses, and qstyleoption_cast() to determine the type of style option. In general you do not need to worry about this unless you want to create your own QStyleOption subclass and your own styles.

Constructors and Destructors

◆ QStyleOptionProgressBarV2() [1/4]

QStyleOptionProgressBarV2::QStyleOptionProgressBarV2 ( )

Constructs a QStyleOptionProgressBarV2, initializing he members variables to their default values.

Definition at line 2824 of file qstyleoption.cpp.

     : QStyleOptionProgressBar(2),
       orientation(Qt::Horizontal), invertedAppearance(false), bottomToTop(false)
 {
 }

◆ QStyleOptionProgressBarV2() [2/4]

QStyleOptionProgressBarV2::QStyleOptionProgressBarV2 ( const QStyleOptionProgressBar & other )

Constructs a copy of the other style option which can be either of the QStyleOptionProgressBar and QStyleOptionProgressBarV2 types.

If the {other} style option's version is 1, the extra members (orientation , invertedAppearance , and bottomToTop ) are set to default values for the new style option. If {other}'s version is 2, the extra members are simply copied.

Functions

◆ operator=()

QStyleOptionProgressBarV2 & QStyleOptionProgressBarV2::operator= ( const QStyleOptionProgressBar & other )

Assigns the other style option to this style option.

The other style option can be either of the QStyleOptionProgressBarV2 or QStyleOptionProgressBar types.

If the {other} style option's version is 1, the extra members (orientation , invertedAppearance , and bottomToTop ) are set to default values for this style option. If {other}'s version is 2, the extra members are simply copied to this style option.

Definition at line 2880 of file qstyleoption.cpp.

 {
     QStyleOptionProgressBar::operator=(other);
 
     const QStyleOptionProgressBarV2 *pb2 = qstyleoption_cast<const QStyleOptionProgressBarV2 *>(&other);
     orientation = pb2 ? pb2->orientation : Qt::Horizontal;
     invertedAppearance = pb2 ? pb2->invertedAppearance : false;
     bottomToTop = pb2 ? pb2->bottomToTop : false;
     return *this;
 }
