Member Function Documentation

depth()

int QEglFSEmulatorScreen::depth ( ) const

overridevirtual

Reimplement in subclass to return current depth of the screen.

Implements QPlatformScreen.

Definition at line 27 of file qeglfsemulatorscreen.cpp.

format()

QImage::Format QEglFSEmulatorScreen::format ( ) const

overridevirtual

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

Implements QPlatformScreen.

Definition at line 32 of file qeglfsemulatorscreen.cpp.

geometry()

QRect QEglFSEmulatorScreen::geometry ( ) const

overridevirtual

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

Implements QPlatformScreen.

Definition at line 17 of file qeglfsemulatorscreen.cpp.

logicalBaseDpi()

QDpi QEglFSEmulatorScreen::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.

Here is the caller graph for this function:

logicalDpi()

QDpi QEglFSEmulatorScreen::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.

nativeOrientation()

Qt::ScreenOrientation QEglFSEmulatorScreen::nativeOrientation ( ) const

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 57 of file qeglfsemulatorscreen.cpp.

orientation()

Qt::ScreenOrientation QEglFSEmulatorScreen::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 62 of file qeglfsemulatorscreen.cpp.

physicalSize()

QSizeF QEglFSEmulatorScreen::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.

refreshRate()

qreal QEglFSEmulatorScreen::refreshRate ( ) const
