---|---|---|---|
getBridgeHeight(context:IPaintContext):Number
Gets the height of the bridge for the given IPaintContext. | IAddBridgesCallback | ||
getBridgeWidth(context:IPaintContext):Number
Gets the width of the bridge for the given IPaintContext. | IAddBridgesCallback | ||
getCrossingStyle(context:IPaintContext):uint
Gets the crossing style to use in the given IPaintContext. | IAddBridgesCallback | ||
getOrientationStyle(context:IPaintContext):uint
Gets the bridge orientation style to use in the given IPaintContext. | IAddBridgesCallback | ||
insertCustomBridge(context:IPaintContext, path:GeneralPath, x1:Number, y1:Number, x2:Number, y2:Number, gapLength:Number):void
Callback that will be used by the BridgeManager if the
getCrossingStyle() method yields BridgeManager.STYLE_CUSTOM
to actually insert a bridge into the given GeneralPath. | IAddBridgesCallback |
getBridgeHeight | () | method |
public function getBridgeHeight(context:IPaintContext):Number
Gets the height of the bridge for the given IPaintContext
.
The height is the default height that will be used for drawing the non-custom crossing styles.
Parameters
context:IPaintContext — The context where the bridge will be created for.
|
Number — The non-negative preferred basic unscaled height of the bridge.
|
getBridgeWidth | () | method |
public function getBridgeWidth(context:IPaintContext):Number
Gets the width of the bridge for the given IPaintContext
.
The width is the preferred length of the segment that will be removed from the original segment if it crosses an obstacle. That bridge will be made larger if multiple obstacle bridges would otherwise overlap. The bridge will be automatically made smaller if it happens to be near the end of a segment and would otherwise extend beyond the end of the segment.
Parameters
context:IPaintContext — The context where the bridge will be created for.
|
Number — The positive preferred width of the bridge.
|
getCrossingStyle | () | method |
public function getCrossingStyle(context:IPaintContext):uint
Gets the crossing style to use in the given IPaintContext
.
The crossing style is detemined by the BridgeManager
's
STYLE
constants: STYLE_GAP
, STYLE_RECTANGLE
,
STYLE_RECTANGLE_SCALED
, STYLE_TWO_SIDES
,
STYLE_TWO_SIDES_SCALED
, STYLE_ARC
,
STYLE_ARC_SCALED
and STYLE_CUSTOM
.
Parameters
context:IPaintContext — The context in which the crossing will be used.
|
uint — The style to use, or BridgeManager.STYLE_CUSTOM in order
to let BridgeManager call insertCustomBridge() .

getOrientationStyle | () | method |
public function getOrientationStyle(context:IPaintContext):uint
Gets the bridge orientation style to use in the given IPaintContext
.
The orientation style is detemined by the BridgeManager
's
ORIENTATION
constants: ORIENTATION_FLOW_RIGHT
,
ORIENTATION_FLOW_LEFT
, ORIENTATION_POSITIVE
,
ORIENTATION_NEGATIVE
, ORIENTATION_RIGHT
,
ORIENTATION_LEFT
, ORIENTATION_DOWN
and
ORIENTATION_UP
.
Parameters
context:IPaintContext — The context in which the style will be used.
|
uint — The style to use. Any value can be returned and will be ignored if the
crossing style which is returned by getCrossingStyle() is set to
BridgeManager.STYLE_CUSTOM .
|
insertCustomBridge | () | method |
public function insertCustomBridge(context:IPaintContext, path:GeneralPath, x1:Number, y1:Number, x2:Number, y2:Number, gapLength:Number):void
Callback that will be used by the BridgeManager
if the
getCrossingStyle()
method yields BridgeManager.STYLE_CUSTOM
to actually insert a bridge into the given GeneralPath
.
When this method is called the GeneralPath
's lastX"
and lastY
coordinates are not yet at x1
and
y1
, respectively.
So most implementation should first GeneralPath.moveTo(x,y)
that location.
Also at the end of the call, implementation should make sure that the GeneralPath's
end is at (x2,y2). The gapLength
is provided for convenience so that
the distance between (x1,y1) and (x2,y2) does not need to be calculated if it is
needed for the drawing.
Parameters
context:IPaintContext — The context for the call.
| |
path:GeneralPath — The path to append the bridge segment to.
| |
x1:Number — The x coordinate of the starting point of the bridge.
| |
y1:Number — The y coordinate of the starting point of the bridge.
| |
x2:Number — The x coordinate of the end point of the bridge.
| |
y2:Number — The y coordinate of the end point of the bridge.
| |
gapLength:Number — The distance between the starting point and the end point.
