Graphics	getGraphics() Returns a Graphics to perform additional drawings.
IlvGrid	getGrid() Returns the grid associated with this interactor context.
IlvTransformer	getTransformer() Returns the transformer of the interactor context.
boolean	isCursorSet() Returns whether the cursor is set in the context.
void	repaint(IlvRect rect) Repaints a region.
void	setCursor(Cursor cursor) Changes the cursor of the context.
void	snapToGrid(IlvPoint p) Changes the coordinates of the specified point to the closest point of the grid.

Method Detail

getTransformer

IlvTransformer getTransformer()

Returns the transformer of the interactor context.

getGraphics

Graphics getGraphics()

Returns a Graphics to perform additional drawings.

getGrid

IlvGrid getGrid()

Returns the grid associated with this interactor context.

Returns:

The grid, or null if there is no grid.

Since:

JViews 5.0

IlvManagerView.getGrid()

setCursor

void setCursor(Cursor cursor)

Changes the cursor of the context.

Parameters:

cursor - The cursor.

getCursor

Cursor getCursor()

Returns the cursor of the context.

Since:

JViews 5.5

isCursorSet

boolean isCursorSet()

Returns whether the cursor is set in the context. The object interactor context can represent a java.awt.Component. For components, getCursor() returns the cursor of the parent component if the cursor was not set on the component itself. This method returns true if the cursor was explicitly set on this component, that is, the result of getCursor() is not the cursor of the parent component but the cursor of this component.

Since:

JViews 8.0

repaint

void repaint(IlvRect rect)

Repaints a region. The dimensions of the rectangle are compatible with the transformer returned by the method getTransformer().

Parameters:

rect - The rectangular region.

Since:

JViews 5.0

ensureVisible

void ensureVisible(IlvPoint p)

Scrolls the context so that the point becomes visible.

Parameters:

p - The point.

snapToGrid

void snapToGrid(IlvPoint p)

Changes the coordinates of the specified point to the closest point of the grid. This method moves the point p to the closest grid point of the grid associated with this context. If no grid is currently associated or the grid is not active, then the parameter is not changed.

Parameters:

p - The point to be snapped to the grid.

IlvGrid, IlvGrid.snap(IlvPoint)

getDefaultXORColor

Color getDefaultXORColor()

Returns a default XOR color for the context.

getDefaultGhostColor

Color getDefaultGhostColor()

Returns a default ghost color for the context.
