Struct qt_gui::q_paint_device::PaintDeviceMetric

#[repr(transparent)]
pub struct PaintDeviceMetric(_);

Describes the various metrics of a paint device.

C++ enum: QPaintDevice::PaintDeviceMetric.

C++ documentation:

Describes the various metrics of a paint device.

Methods

impl PaintDeviceMetric

pub fn to_int(&self) -> c_int

impl PaintDeviceMetric

pub const PdmWidth: PaintDeviceMetric

The width of the paint device in default coordinate system units (e.g. pixels for QPixmap and QWidget). See also width(). (C++ enum variant: PdmWidth = 1)

pub const PdmHeight: PaintDeviceMetric

The height of the paint device in default coordinate system units (e.g. pixels for QPixmap and QWidget). See also height(). (C++ enum variant: PdmHeight = 2)

pub const PdmWidthMM: PaintDeviceMetric

The width of the paint device in millimeters. See also widthMM(). (C++ enum variant: PdmWidthMM = 3)

pub const PdmHeightMM: PaintDeviceMetric

The height of the paint device in millimeters. See also heightMM(). (C++ enum variant: PdmHeightMM = 4)

pub const PdmNumColors: PaintDeviceMetric

The number of different colors available for the paint device. See also colorCount(). (C++ enum variant: PdmNumColors = 5)

pub const PdmDepth: PaintDeviceMetric

The bit depth (number of bit planes) of the paint device. See also depth(). (C++ enum variant: PdmDepth = 6)

pub const PdmDpiX: PaintDeviceMetric

The horizontal resolution of the device in dots per inch. See also logicalDpiX(). (C++ enum variant: PdmDpiX = 7)

pub const PdmDpiY: PaintDeviceMetric

The vertical resolution of the device in dots per inch. See also logicalDpiY(). (C++ enum variant: PdmDpiY = 8)

pub const PdmPhysicalDpiX: PaintDeviceMetric

The horizontal resolution of the device in dots per inch. See also physicalDpiX(). (C++ enum variant: PdmPhysicalDpiX = 9)

pub const PdmPhysicalDpiY: PaintDeviceMetric

The vertical resolution of the device in dots per inch. See also physicalDpiY(). (C++ enum variant: PdmPhysicalDpiY = 10)

pub const PdmDevicePixelRatio: PaintDeviceMetric

The device pixel ratio for device. Common values are 1 for normal-dpi displays and 2 for high-dpi "retina" displays. (C++ enum variant: PdmDevicePixelRatio = 11)

pub const PdmDevicePixelRatioScaled: PaintDeviceMetric

The scaled device pixel ratio for the device. This is identical to PdmDevicePixelRatio, except that the value is scaled by a constant factor in order to support paint devices with fractional scale factors. The constant scaling factor used is devicePixelRatioFScale(). This enum value has been introduced in Qt 5.6. (C++ enum variant: PdmDevicePixelRatioScaled = 12)
