The TMDrawManager interface should be implemented
by every class that implements algorithms for drawing
TMNode.

The methods to implements are :

  • getFilling(), to compute and return the filling of a node
  • getTooltip(), to compute and return the tooltip of a node
  • getTitle(), to compute and return the title (name) of a node
  • getTitleColor(), to compute and return the color of the title

As the filling and tooltip of a node could depends of its size,
methods get a TMNodeAdapter reference and not directly a TMNode.
To get the TMNode, call nodeAdapter.getNode().
To get the size of the TMNode, call nodeAdapter.getSize().
To pass information from filling to tooltip, use setUserData() and
getUserData() methods.

As computing the drawing of a node is dependant of the kind of
TMNode, a TMComputeDraw should test the kind of TMNode returned by
nodeAdapter.getNode(), and throw an TMExceptionBadTMNodeKind
if there is incompatibility.
The isCompatibleWith method should test the kind of TMNode
passed in parameter and return true if this TMComputeDraw
is compatible with it.

getTitle

public String getTitle(
TMNodeAdapter nodeAdapter) throws TMExceptionBadTMNodeKind, TMExceptionBadTMNodeKind

Returns the title of the node.
Parameters:
nodeAdapter:
the node for which we want the title
Returns:
  • the title of the node
Throws:

getTitleColor

public Paint getTitleColor(
TMNodeAdapter nodeAdapter) throws TMExceptionBadTMNodeKind, TMExceptionBadTMNodeKind

Returns the color of the title of the node.
Parameters:
nodeAdapter:
the node for which we want the title

  • the title of the node
Throws:

getTooltip

public String getTooltip(
TMNodeAdapter nodeAdapter) throws TMExceptionBadTMNodeKind, TMExceptionBadTMNodeKind

Returns the tooltip of the node.
Parameters:
nodeAdapter:
the node for which we want the tooltip
Returns:
  • the tooltip of the node
Throws:

isCompatibleWith

public boolean isCompatibleWith(
TMNode node)

Test if this TMComputeDraw could be used
with the kind of TMNode passed in parameter.
Parameters:
node:
the TMNode to test the compatibility with
Returns:
  • true if this kind of node is compatible;
    false otherwise
