Modifier and Type | Method and Description |
---|---|
private void |
addHighlighting()
Takes the data from computeHelperLine to determine which ways/nodes should be highlighted
(if feature enabled).
|
private JCheckBoxMenuItem |
addMenuItem() |
private static void |
addRemoveSelection(DataSet ds,
OsmPrimitive toAdd,
OsmPrimitive toRemove) |
private static void |
adjustNode(Collection<Pair<Node,Node>> segs,
Node n)
Adjusts the position of a node to lie on a segment (or a segment
intersection).
|
private void |
computeHelperLine()
This method prepares data required for painting the "helper line" from
the last used position to the mouse cursor.
|
private void |
continueWayFromNode(Way way,
Node node)
if one of the ends of
way is given node ,
then set currentBaseNode = node and previousNode = adjacent node of way |
void |
destroy()
Called when the object has been destroyed.
|
(package private) static double |
det(double a,
double b,
double c,
double d) |
private void |
determineCurrentBaseNodeAndPreviousNode(Collection<OsmPrimitive> selection)
Helper function that sets fields currentBaseNode and previousNode
|
void |
doKeyPressed(KeyEvent e)
This is called when key press event is actually pressed
(no fake events while holding key)
|
void |
doKeyReleased(KeyEvent e)
This is called when key press event is actually released
(no fake events while holding key)
|
void |
enterMode()
Makes this map mode active.
|
void |
exitMode()
Makes this map mode inactive.
|
private Node |
findNodeToContinueFrom(Node selectedNode,
Way selectedWay)
Finds a node to continue drawing from.
|
private void |
finishDrawing()
This function should be called when the user wishes to finish his current draw action.
|
Node |
getCurrentBaseNode()
Replies the current base node, after having checked it is still usable (see #11105).
|
Collection<OsmPrimitive> |
getInProgressSelection()
Get selected primitives, while draw action is in progress.
|
String |
getModeHelpText() |
static Way |
getWayForNode(Node n) |
private void |
insertNodeIntoAllNearbySegments(List<WaySegment> wss,
Node n,
Collection<OsmPrimitive> newSelection,
Collection<Command> cmds,
List<Way> replacedWays,
List<Way> reuseWays) |
private boolean |
isSelfContainedWay(Way selectedWay,
Node currentNode,
Node targetNode)
Prevent creation of ways that look like this: <---->
This happens if users want to draw a no-exit-sideway from the main way like this:
^
|<---->
|
The solution isn't ideal because the main way will end in the side way, which is bad for
navigation software ("drive straight on") but at least easier to fix.
|
boolean |
layerIsSupported(Layer l)
Determines if layer
l is supported by this map mode. |
void |
modifiersChanged(int modifiers)
redraw to (possibly) get rid of helper line if selection changes.
|
void |
mouseDragged(MouseEvent e) |
void |
mouseExited(MouseEvent e)
Repaint on mouse exit so that the helper line goes away.
|
void |
mouseMoved(MouseEvent e) |
void |
mousePressed(MouseEvent e) |
void |
mouseReleased(MouseEvent e)
If user clicked with the left button, add a node at the current mouse
position.
|
void |
paint(Graphics2D g,
MapView mv,
Bounds box)
Paint the dataset using the engine set.
|
private static void |
pruneSuccsAndReverse(List<Integer> is) |
private void |
readPreferences() |
private boolean |
redrawIfRequired()
Checks if a map redraw is required and does so if needed.
|
private boolean |
removeHighlighting()
Removes target highlighting from primitives.
|
void |
selectionChanged(Collection<? extends OsmPrimitive> newSelection)
redraw to (possibly) get rid of helper line if selection changes.
|
private static void |
showStatusInfo(double angle,
double hdg,
double distance,
boolean activeFlag) |
private void |
tryAgain(MouseEvent e) |
private void |
tryToMoveNodeOnIntersection(List<WaySegment> wss,
Node n) |
private void |
tryToSetBaseSegmentForAngleSnap()
This method is used to detect segment under mouse and use it as reference for angle snapping
|
protected void |

something in the JOSM state changes, i.e.
