inline

Definition at line 79 of file qeglfskmsscreen_p.h.

◆ logicalBaseDpi()

QDpi QEglFSKmsScreen::logicalBaseDpi ( ) const

overridevirtual

Reimplement to return the base logical DPI for the platform.

This DPI value should correspond to a standard-DPI (1x) display. The default implementation returns 96.

QtGui will use this value (together with logicalDpi) to compute the scale factor when high-DPI scaling is enabled, as follows: factor = logicalDPI / baseDPI

Reimplemented from QPlatformScreen.

Definition at line 130 of file qeglfskmsscreen.cpp.

◆ logicalDpi()

QDpi QEglFSKmsScreen::logicalDpi ( ) const

overridevirtual

Reimplement this function in subclass to return the logical horizontal and vertical dots per inch metrics of the screen.

The logical dots per inch metrics are used by Qt to scale the user interface.

The default implementation returns logicalBaseDpi(), which results in a UI scale factor of 1.0.

overridevirtual

Reimplement this function in subclass to return the native orientation of the screen, e.g.

the orientation where the logo sticker of the device appears the right way up.

The default implementation returns Qt::PrimaryOrientation.

Reimplemented from QPlatformScreen.

Definition at line 135 of file qeglfskmsscreen.cpp.

◆ orientation()

Qt::ScreenOrientation QEglFSKmsScreen::orientation ( ) const

overridevirtual

Reimplement this function in subclass to return the current orientation of the screen, for example based on accelerometer data to determine the device orientation.

The default implementation returns Qt::PrimaryOrientation.

Reimplemented from QPlatformScreen.

Definition at line 140 of file qeglfskmsscreen.cpp.

Definition at line 223 of file qeglfskmsscreen.cpp.

◆ physicalSize()

QSizeF QEglFSKmsScreen::physicalSize ( ) const

overridevirtual

Reimplement this function in subclass to return the physical size of the screen, in millimeters.

The physical size represents the actual physical dimensions of the display.

The default implementation takes the pixel size of the screen, considers a resolution of 100 dots per inch, and returns the calculated physical size. A device with a screen that has different resolutions will need to be supported by a suitable reimplementation of this function.

◆ subpixelAntialiasingTypeHint()

QPlatformScreen::SubpixelAntialiasingType QEglFSKmsScreen::subpixelAntialiasingTypeHint ( ) const

overridevirtual

Returns a hint about this screen's subpixel layout structure.

The default implementation queries the {QT_SUBPIXEL_AA_TYPE} env variable. This is just a hint because most platforms don't have a way to retrieve the correct value from hardware and instead rely on font configurations.

Reimplemented from QPlatformScreen.

◆ virtualSiblings()

QList< QPlatformScreen * > QEglFSKmsScreen::virtualSiblings ( ) const

inlineoverridevirtual
