The QStyleOptionTabV3 class is used to describe the parameters necessary for drawing a tabs in Qt 4.5 or above.
An instance of the QStyleOptionTabV3 class has type SO_Tab and version 3. 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 QStyleOptionTab, QStyleOptionTabV2 and QStyleOptionTabV3. One way to achieve this is to use the QStyleOptionTabV3 copy constructor. For example:
if (const QStyleOptionTab *tabOption = qstyleoption_cast<const QStyleOptionTab *>(option)) { QStyleOptionTabV2 tabV2(*tabOption); // draw the tab using tabV2 }
In the example above: If tabOption's version is 1, the extra member (iconSize) will be set to an invalid size for tabV2. If tabOption's version is 2, the constructor will simply copy the tab's iconSize.
For an example demonstrating how style options can be used, see the Styles example.
See also QStyleOptionTab and QStyleOption.
This enum is used to hold information about the version of the style option, and is defined for each QStyleOption subclass.
Constant | Value | Description |
---|---|---|
QStyleOptionTabV3::Version | 3 | 3 |
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.
See also StyleOptionType.
Constructs a QStyleOptionTabV3.
Constructs a copy of the other style option.
Constructs a copy of the other style option.
Constructs a QStyleOptionTabV3 copy of the other style option which can be either of the QStyleOptionTabV3, QStyleOptionTabV2 or QStyleOptionTab types.
If the other style option's version is 1 or 2, the new style option's leftButtonSize and rightButtonSize is set to an invalid value. If its version is 3, its leftButtonSize and rightButtonSize values are simply copied to the new style option.
Assigns the other style option to this QStyleOptionTabV3. The other style option can be either of the QStyleOptionTabV3, QStyleOptionTabV2 or QStyleOptionTab types.
If the other style option's version is 1 or 2, the new style option's leftButtonSize and rightButtonSize is set to an invalid value. If its version is 3, its leftButtonSize and rightButtonSize values are simply copied to the new style option.
This variable holds whether the tabbar is in document mode.
The default value is false;
This variable holds the size for the left widget on the tab.
The default value is QSize(-1, -1), i.e. an invalid size;
This variable holds the size for the right widget on the tab.
The default value is QSize(-1, -1), i.e. an invalid size;
