SwipeContainer class
@class SwipeContainer A container that holds elements that be swiped through to the left or right. The container will animate to the next element or snaps back to the shown element if a too small drag is performed. All elements added must have the same dimensions. This widget is part of the TouchGFX Open Widget Repository. https://github.com/draupnergraphics/touchgfx-widgets Widget has been slightly modified for this demo. @see touchgfx::Container

add()
@fn virtual void SwipeContainer::add(touchgfx::Drawable& screen); Adds a screen to the container. Note that all screens must have the same width and height. Read more...
setSwipeCutoff()
@fn virtual void SwipeContainer::setSwipeCutoff(uint16_t cutoff); Set the swipe cutoff which indicates how far you should drag a screen before it results in a screen change. Read more...
setDotIndicatorXY()
@fn void SwipeContainer::setDotIndicatorXY(uint16_t x, uint16_t y); Sets the x and y position of the dot indicator. Read more...
setDotIndicatorXYWithCenteredX()
@fn void SwipeContainer::setDotIndicatorXYWithCenteredX(uint16_t x, uint16_t y); Sets the x and y position of the dot indicator. The value specified as x will be the center coordinate of the dot indicators. Note that this method should first be used after all screens have been added, the setDotIndicatorBitmaps has been called and the dot indicator therefore has the correct width. Read more...
setDotIndicatorBitmaps()
@fn void SwipeContainer::setDotIndicatorBitmaps(const touchgfx::Bitmap& normalDot, const touchgfx::Bitmap& highlightedDot); Sets the bitmaps that are used by the dot indicator. Read more...
setEndSwipeElasticWidth()
@fn void SwipeContainer::setEndSwipeElasticWidth(uint16_t width); When dragging either one of the end screens a part of the background will become visible until the user stop dragging and the end screen swipes back to its position. The width of this area is set by this method. Read more...
