◆ cursor()

QPlatformCursor * QDirectFbScreen::cursor ( ) const

inlineoverridevirtual

Reimplement this function in subclass to return the cursor of the screen.

The default implementation returns \nullptr.

Reimplemented from QPlatformScreen.

References QScopedPointer< T, Cleanup >::data().

Here is the call graph for this function:

◆ depth()

int QDirectFbScreen::depth ( ) const

inlineoverridevirtual

Reimplement in subclass to return current depth of the screen.

Implements QPlatformScreen.

◆ format()

QImage::Format QDirectFbScreen::format ( ) const

inlineoverridevirtual

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

Implements QPlatformScreen.

Definition at line 24 of file qdirectfbscreen.h.

References m_format.

◆ geometry()

QRect QDirectFbScreen::geometry ( ) const

inlineoverridevirtual

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

Implements QPlatformScreen.

Definition at line 22 of file qdirectfbscreen.h.

References m_geometry.

◆ physicalSize()

QSizeF QDirectFbScreen::physicalSize ( ) const

inlineoverridevirtual

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.
