Member Function Documentation

◆ depth() [1/2]

int QVkKhrDisplayScreen::depth ( ) const
inlineoverridevirtual

Reimplement in subclass to return current depth of the screen.

Implements QPlatformScreen.

Definition at line 44 of file qvkkhrdisplayintegration.cpp.

◆ depth() [2/2]

int QVkKhrDisplayScreen::depth ( ) const
inlineoverridevirtual

Reimplement in subclass to return current depth of the screen.

Implements QPlatformScreen.

Definition at line 44 of file qvkkhrdisplayintegration.cpp.

◆ format() [1/2]

QImage::Format QVkKhrDisplayScreen::format ( ) const
inlineoverridevirtual

Reimplement in subclass to return the image format which corresponds to the screen format.

Implements QPlatformScreen.

Definition at line 45 of file qvkkhrdisplayintegration.cpp.

◆ format() [2/2]

QImage::Format QVkKhrDisplayScreen::format ( ) const
inlineoverridevirtual

Reimplement in subclass to return the image format which corresponds to the screen format.

Implements QPlatformScreen.

Definition at line 45 of file qvkkhrdisplayintegration.cpp.

◆ geometry() [1/2]

QRect QVkKhrDisplayScreen::geometry ( ) const
inlineoverridevirtual

Reimplement in subclass to return the pixel geometry of the screen.

Implements QPlatformScreen.

Definition at line 43 of file qvkkhrdisplayintegration.cpp.

◆ geometry() [2/2]

QRect QVkKhrDisplayScreen::geometry ( ) const
inlineoverridevirtual

Reimplement in subclass to return the pixel geometry of the screen.

Implements QPlatformScreen.

Definition at line 43 of file qvkkhrdisplayintegration.cpp.

◆ name() [1/2]

QString QVkKhrDisplayScreen::name ( ) const
inlineoverridevirtual

Reimplemented from QPlatformScreen.

Definition at line 46 of file qvkkhrdisplayintegration.cpp.

◆ name() [2/2]

QString QVkKhrDisplayScreen::name ( ) const
inlineoverridevirtual

Reimplemented from QPlatformScreen.

Definition at line 46 of file qvkkhrdisplayintegration.cpp.

◆ physicalSize() [1/2]

QSizeF QVkKhrDisplayScreen::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.
