Functions

◆ depth()

int QUIKitScreen::depth ( ) const

inlinevirtual

Reimplement in subclass to return current depth of the screen.

Implements QPlatformScreen.

Definition at line 58 of file quikitscreen.h.

58 { return m_depth; }

QUIKitScreen::m_depth

int m_depth

Definition: quikitscreen.h:67

◆ format()

QImage::Format QUIKitScreen::format ( ) const

inlinevirtual

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

Implements QPlatformScreen.

Definition at line 59 of file quikitscreen.h.

59 { return m_format; }

QUIKitScreen::m_format

QImage::Format m_format

Definition: quikitscreen.h:68

◆ geometry()

QRect QUIKitScreen::geometry ( ) const

inlinevirtual

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

Implements QPlatformScreen.

Definition at line 57 of file quikitscreen.h.

57 { return m_geometry; }

QUIKitScreen::m_geometry

QRect m_geometry

Definition: quikitscreen.h:66

◆ physicalSize()

QSize QUIKitScreen::physicalSize ( ) const

inlinevirtual

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

This function is used by QFont to convert point sizes to pixel sizes.

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.

Reimplemented from QPlatformScreen.
