actualSize()

QSize QAndroidPlatformIconEngine::actualSize ( const QSize & size, QIcon::Mode mode, QIcon::State state )

overridevirtual

Returns the actual size of the icon the engine provides for the requested size, mode and state.

The default implementation returns the given size.

Reimplemented from QIconEngine.

Here is the call graph for this function:

availableSizes()

QList< QSize > QAndroidPlatformIconEngine::availableSizes ( QIcon::Mode mode, QIcon::State state )

overridevirtual

Since

4.5

Returns sizes of all images that are contained in the engine for the specific mode and state.

Reimplemented from QIconEngine.

Definition at line 555 of file qandroidplatformiconengine.cpp.

clone()

QIconEngine * QAndroidPlatformIconEngine::clone ( ) const

overridevirtual

Reimplement this method to return a clone of this icon engine.

Implements QIconEngine.

References QAndroidPlatformIconEngine().

Here is the call graph for this function:

iconName()

QString QAndroidPlatformIconEngine::iconName ( )

overridevirtual

Since

4.7

Returns the name used to create the engine, if available.

Reimplemented from QIconEngine.

Definition at line 539 of file qandroidplatformiconengine.cpp.

isNull()

bool QAndroidPlatformIconEngine::isNull ( )

overridevirtual

Since

5.7

Returns true if this icon engine represent a null QIcon.

Reimplemented from QIconEngine.

Here is the call graph for this function:

key()

QString QAndroidPlatformIconEngine::key ( ) const

overridevirtual

\variable QIconEngine::ScaledPixmapArgument::size

The requested size of the pixmap.

\variable QIconEngine::ScaledPixmapArgument::mode

The requested mode of the pixmap.

See also

QIcon::Mode

\variable QIconEngine::ScaledPixmapArgument::state

The requested state of the pixmap.

See also

QIcon::State

\variable QIconEngine::ScaledPixmapArgument::scale

The requested scale of the pixmap.

\variable QIconEngine::ScaledPixmapArgument::pixmap

The pixmap that is the best match for the given \l size, \l mode, \l state, and \l scale. This is an output parameter that is set after calling \l virtual_hook().

Returns a key that identifies this icon engine.

Reimplemented from QIconEngine.

Definition at line 534 of file qandroidplatformiconengine.cpp.

paint()

void QAndroidPlatformIconEngine::paint ( QPainter * painter, const QRect & rect, QIcon::Mode mode, QIcon::State state )

overridevirtual

Uses the given painter to paint the icon with the required mode and state into the rectangle rect.

Implements QIconEngine.

pixmap()

QPixmap QAndroidPlatformIconEngine::pixmap ( const QSize & size, QIcon::Mode mode, QIcon::State state )

overridevirtual

Returns the icon as a pixmap with the required size, mode, and state.

The default implementation creates a new pixmap and calls paint() to fill it.

Reimplemented from QIconEngine.

Definition at line 565 of file qandroidplatformiconengine.cpp.

Here is the call graph for this function:

scaledPixmap()

QPixmap QAndroidPlatformIconEngine::scaledPixmap ( const QSize & size, QIcon::Mode mode, QIcon::State state, qreal scale )

overridevirtual

Since

5.9

Returns a pixmap for the given size, mode, state and scale.

The scale argument is typically equal to the \l {High DPI} {device pixel ratio} of the display.

Note

Some engines may cast scale to an integer.
