Method Detail

grappaClicked

void grappaClicked(Subgraph subg,
                   Element elem,
                   GrappaPoint pt,
                   int modifiers,
                   int clickCount,
                   GrappaPanel panel)

The method called when a single mouse click occurs on a displayed subgraph.

Parameters:

subg - displayed subgraph where action occurred

elem - subgraph element in which action occurred

pt - the point where the action occurred (graph coordinates)

modifiers - mouse modifiers in effect

panel - specific panel where the action occurred

grappaPressed

void grappaPressed(Subgraph subg,
                   Element elem,
                   GrappaPoint pt,
                   int modifiers,
                   GrappaPanel panel)

The method called when a mouse press occurs on a displayed subgraph.

Parameters:

subg - displayed subgraph where action occurred

elem - subgraph element in which action occurred

pt - the point where the action occurred (graph coordinates)

modifiers - mouse modifiers in effect

panel - specific panel where the action occurred

grappaReleased

void grappaReleased(Subgraph subg,
                    Element elem,
                    GrappaPoint pt,
                    int modifiers,
                    Element pressedElem,
                    GrappaPoint pressedPt,
                    int pressedModifiers,
                    GrappaBox outline,
                    GrappaPanel panel)

The method called when a mouse release occurs on a displayed subgraph.

Parameters:

subg - displayed subgraph where action occurred

elem - subgraph element in which action occurred

pt - the point where the action occurred (graph coordinates)

modifiers - mouse modifiers in effect

pressedElem - subgraph element in which the most recent mouse press occurred

pressedPt - the point where the most recent mouse press occurred (graph coordinates)

pressedModifiers - mouse modifiers in effect when the most recent mouse press occurred

outline - enclosing box specification from the previous drag position (for XOR reset purposes)

panel - specific panel where the action occurred

grappaDragged

void grappaDragged(Subgraph subg,
                   GrappaPoint currentPt,
                   int currentModifiers,
                   Element pressedElem,
                   GrappaPoint pressedPt,
                   int pressedModifiers,
                   GrappaBox outline,
                   GrappaPanel panel)

The method called when a mouse drag occurs on a displayed subgraph.

Parameters:

subg - displayed subgraph where action occurred

currentPt - the current drag point

currentModifiers - the current drag mouse modifiers

pressedElem - subgraph element in which the most recent mouse press occurred

pressedPt - the point where the most recent mouse press occurred (graph coordinates)

pressedModifiers - mouse modifiers in effect when the most recent mouse press occurred

outline - enclosing box specification from the previous drag position (for XOR reset purposes)

panel - specific panel where the action occurred

grappaTip

java.lang.String grappaTip(Subgraph subg,
                           Element elem,
                           GrappaPoint pt,
                           int modifiers,
                           GrappaPanel panel)

The method called when a element tooltip is needed.

Parameters:

subg - displayed subgraph where action occurred

elem - subgraph element in which action occurred

pt - the point where the action occurred (graph coordinates)

modifiers - mouse modifiers in effect

panel - specific panel where the action occurred

Returns:

the tip to be displayed or null
