詳細描述

QStyleOptionSlider contains all the information that QStyle 函數需要繪製 QSlider and QScrollBar .

齣於性能原因，有很少成員函數，且對成員變量的訪問是直接的 (即：使用 . or -> 運算符)。這使結構易於使用並強調這些隻需通過樣式函數使用參數。

enum QStyleOptionSlider:: StyleOptionType

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

常量	值	描述
`QStyleOptionSlider::Type`	`SO_Slider`	提供樣式選項的類型 ( SO_Slider 對於此類)。

類型內部使用通過 QStyleOption ，其子類，和 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.

另請參閱 StyleOptionVersion .

enum QStyleOptionSlider:: StyleOptionVersion

This enum is used to hold information about the version of the style option, and is defined for each QStyleOption 子類。

常量	值	描述
`QStyleOptionSlider::Version`	`1`	1

版本的使用通過 QStyleOption 子類以實現擴展在不破壞兼容性的情況下。若使用 qstyleoption_cast ()，通常不需要校驗它。

bool QStyleOptionSlider:: dialWrapping

This variable holds whether the dial should wrap or not

The default value is false, i.e. the dial is not wrapped.

另請參閱 QDial::wrapping ().

int QStyleOptionSlider:: maximum

This variable holds the maximum value for the slider

默認值為 0。

int QStyleOptionSlider:: minimum

This variable holds the minimum value for the slider

默認值為 0。

qreal QStyleOptionSlider:: notchTarget

This variable holds the number of pixel between notches

The default value is 0.0.

另請參閱 QDial::notchTarget ().

Qt::Orientation QStyleOptionSlider:: orientation

This variable holds the slider's orientation (horizontal or vertical)

The default orientation is Qt::Horizontal .

另請參閱 Qt::Orientation .

int QStyleOptionSlider:: pageStep

This variable holds the size of the page step of the slider

默認值為 0。

另請參閱 QAbstractSlider::pageStep .

int QStyleOptionSlider:: singleStep

This variable holds the size of the single step of the slider

默認值為 0。

另請參閱 QAbstractSlider::singleStep .

int QStyleOptionSlider:: sliderPosition

This variable holds the position of the slider handle

If the slider has active feedback (i.e., QAbstractSlider::tracking is true), this value will be the same as sliderValue . Otherwise, it will have the current position of the handle. The default value is 0.

另請參閱 QAbstractSlider::tracking and sliderValue .

int QStyleOptionSlider:: sliderValue

This variable holds the value of the slider

If the slider has active feedback (i.e., QAbstractSlider::tracking is true), this value will be the same as sliderPosition . Otherwise, it will have the value the slider had before the mouse was pressed.

默認值為 0。

另請參閱 QAbstractSlider::tracking and sliderPosition .

int QStyleOptionSlider:: tickInterval

This variable holds the interval that should be drawn between tick marks

默認值為 0。

QSlider::TickPosition QStyleOptionSlider:: tickPosition

This variable holds the position of the slider's tick marks, if any

默認值為 QSlider::NoTicks .

另請參閱 QSlider::TickPosition .

bool QStyleOptionSlider:: upsideDown

This variable holds the slider control orientation

Normally a slider increases as it moves up or to the right; upsideDown indicates that it should do the opposite (increase as it moves down or to the left). The default value is false, i.e. the slider increases as it moves up or to the right.
