Detailed Description

The QRoundProgressBar class represents a circular progress bar and maintains its API similar to the QProgressBar.

Styles

QRoundProgressBar currently supports Donut, Pie and Line styles. See setBarStyle() for more details.

Colors

Generally QRoundProgressBar uses its palette and font attributes to define how it will look.

The following QPalette members are considered:

QPalette::Window background of the whole widget (normally should be set to Qt::NoBrush)
QPalette::Base background of the non-filled progress bar area (should be set to Qt::NoBrush to make it transparent)
QPalette::AlternateBase background of the central circle where the text is shown (for Donut style)
QPalette::Shadow foreground of the non-filled progress bar area (i.e. border color)
QPalette::Highlight background of the filled progress bar area
QPalette::Text color of the text shown in the center

Create a QPalette with given attributes and apply it via setPalette().

Color gradient

Donut and Pie styles allow to use color gradient for currernt value area instead of plain brush fill. See setDataColors() for more details.

Value text

Value text is generally drawn inside the QRoundProgressBar using its font() and QPalette::Text role from its palette().

To define pattern of the text, use setFormat() function (see Qt's QProgressBar for more details).

To define number of decimals to be shown, use setDecimals() function.

Font

To use own font for value text, apply it via setFont().

By default, font size will be adjusted automatically to fit the inner circle of the widget.

◆ setDataColors()

void QRoundProgressBar::setDataColors ( const QGradientStops & stopPoints )
