com.sun.midp.chameleon.layers.ScrollArrowLayer
| ScrollArrowLayer | | public class ScrollArrowLayer extends ScrollIndLayer (Code) | | A ScrollArrowLayer is a region of the display used for showing scroll indicator
status arrows.
|
| Field Summary | |
| protected boolean | downViz
| | protected boolean | upViz
|
| downViz | | protected boolean downViz(Code) | | True if down arrow is visible
|
| upViz | | protected boolean upViz(Code) | | True if up arrow is visible
|
| ScrollArrowLayer | | public ScrollArrowLayer(CLayer layer)(Code) | | Construct a new ScrollIndLayer, visible, but transparent :)
|
| ScrollArrowLayer | | public ScrollArrowLayer(CLayer layer, ScrollListener listener)(Code) | | Additional constructor.
Parameters:
layer - the scrollable controlling the scrolling layer
Parameters:
listener - the scrolling listener |
| paintBody | | protected void paintBody(Graphics g)(Code) | | Paint the scroll indicator. The indicator arrows may be appear
individually
or together, and may vary in appearance based on whether they appear
in the normalsoft button region or an alert's softbutton region.
The visible state is based on the state of the alertMode,
upViz, and downViz variables set by the
setVerticalScroll method.
Parameters:
g - the graphics context to paint in |
| pointerInput | | public boolean pointerInput(int type, int x, int y)(Code) | | Handle input from a pen tap. Parameters describe
the type of pen event and the x,y location in the
layer at which the event occurred. Important : the
x,y location of the pen tap will already be translated
into the coordinate space of the layer.
Parameters:
type - the type of pen event
Parameters:
x - the x coordinate of the event
Parameters:
y - the y coordinate of the event |
| setBounds | | public void setBounds()(Code) | | Calculate layer bounds depending on the scrollable
|
| setScrollable | | public boolean setScrollable(CLayer layer)(Code) | | Set new scrollable
Parameters:
layer - new scrollable controlling the scrolling layer true if the scrollable is changed, false - otherwise |
| setVerticalScroll | | public void setVerticalScroll(int scrollPosition, int scrollProportion)(Code) | | Set the current vertical scroll position and proportion.
Parameters:
scrollPosition - vertical scroll position.
Parameters:
scrollProportion - vertical scroll proportion. |
