Constructor Detail

GesturePointsDisplay

public GesturePointsDisplay()

GesturePointsDisplay

public GesturePointsDisplay(Gesture g)

GesturePointsDisplay

public GesturePointsDisplay(Gesture g,
                            int x,
                            int y)

Set offsets and gesture at the same time

Method Detail

getGesture

public Gesture getGesture()

setGesture

public void setGesture(Gesture g)

Set the displayed gesture. Does not automatically resize itself, so you may want to call revalidate after setting the gesture.

getAutoCentering

public boolean getAutoCentering()

When autoCentering is on, the gesture is automatically centered in the widget.

setAutoCentering

public void setAutoCentering(boolean on)

When autoCentering is on, the gesture is automatically centered in the widget.

centerGesture

public void centerGesture()

Doesn't really center it for now, just moves it to the origin

setPreferredSize

public void setPreferredSize(Dimension preferredSize)

Overrides:

setPreferredSize in class JComponent

getPreferredSize

public Dimension getPreferredSize()

Overrides:

getPreferredSize in class JComponent

getMinimumSize

public Dimension getMinimumSize()

Overrides:

getMinimumSize in class JComponent

paint

public void paint(Graphics graphics)

Overrides:

paint in class JComponent

update

public void update(Observable gesture,
                   Object arg)

Specified by:

update in interface Observer

setSelected

public void setSelected(boolean on)

getSelected

public boolean getSelected()

toggleSelected

public boolean toggleSelected()

setOffset

public void setOffset(int x,
                      int y)

Space to allow around the gesture

setShowPoints

public void setShowPoints(boolean on)

Whether to draw the individual points that compose the gesture

getShowPoints

public boolean getShowPoints()

getShowSelected

public boolean getShowSelected()

setShowSelected

public void setShowSelected(boolean on)

If true, disables showing the fact that the gesture is selected

setNarrowed

public void setNarrowed(boolean on)

Borrowed narrowing from emacs. Right now, makes narrowed things highlight instead of hiding non-narrowed things.

toggleNarrowed

public void toggleNarrowed()

setAnimated

public void setAnimated(boolean on)

isAnimated

public boolean isAnimated()
