Use this method to update the pointer's position.

References bVisible, maViews, mbVisible, mrScreenUpdater, and slideshow::internal::ScreenUpdater::requestImmediateUpdate().

viewAdded()

void slideshow::internal::PointerSymbol::viewAdded ( const UnoViewSharedPtr &  rView )

overrideprivatevirtual

Notify new view.

Parameters

rView

The newly added view

Implements slideshow::internal::ViewEventHandler.

viewChanged()

void slideshow::internal::PointerSymbol::viewChanged ( const UnoViewSharedPtr &  rView )

overrideprivatevirtual

Notify changed view.

Reasons for a viewChanged notification can be different view size, transformation, or other device properties (color resolution or profile, etc.)

Parameters

rView

The changed view

Implements slideshow::internal::ViewEventHandler.

Definition at line 145 of file pointersymbol.cxx.

References calcSpritePos(), and maViews.

viewRemoved()

void slideshow::internal::PointerSymbol::viewRemoved ( const UnoViewSharedPtr &  rView )

overrideprivatevirtual

Notify removed view.

Parameters

rView

The removed view

Implements slideshow::internal::ViewEventHandler.

Definition at line 134 of file pointersymbol.cxx.

References maViews.

viewsChanged() [1/2]

void slideshow::internal::PointerSymbol::viewsChanged ( )

overrideprivatevirtual

Notify that all views changed.

Reasons for a viewChanged notification can be different view size, transformation, or other device properties (color resolution or profile, etc.)

Note that this method avoids hidden inefficiencies (O(n^2) behaviour when viewChanged() needs to perform linear searches)

Implements slideshow::internal::ViewEventHandler.
