Constructor Details

JZoomport

public JZoomport(JComponent toZoom,
 @Nonnull
 JZoomPane zoomPane)

Method Details

processKeyBinding

protected boolean processKeyBinding(KeyStroke ks,
 KeyEvent e,
 int condition,
 boolean pressed)

The zoomed component is not part of the Swing component hierarchy, so its key bindings would never be consulted. This forwards WHEN_FOCUSED bindings of the zoomed component when this zoomport has focus, similar to how a view inside JScrollPane receives them directly.

Overrides:

processKeyBinding in class JComponent

getZoom

public final double getZoom()

Returns current zoom factor

Returns:

double zoom factor

setZoom

public final void setZoom(double zoom)

Sets zoom value

fitZoom

public final void fitZoom()

Sets zoom value to fit canvas and center

fitZoom

public final void fitZoom(int hpadding,
 int vpadding)

Sets zoom value to fit canvas and center. Also adds some padding

setZoomAroundCenter

public final void setZoomAroundCenter(double zoom)

Sets zoom value keeping the center still

getLocationOnCanvas

public Point2D.Double getLocationOnCanvas(Point2D panelLocation)

getLocationOnPanel

public Point2D.Double getLocationOnPanel(Point2D canvasLocation)

recalculateBounds

public void recalculateBounds()

If the zoomable element changes size when zoom or viewport size changes this has to be implemented for proper operation.

paint

public void paint(Graphics g)

Overrides:

paint in class JComponent

setViewPosition

public void setViewPosition(Point point)

setViewPosX

public void setViewPosX(double viewPosX)
