public void paint(Graphics g)

Description copied from class: G2dComponent

Paints the contents of the panel.

Overrides:

paint in class G2dComponent

getPixelSpacing

public int getPixelSpacing()

setPixelSpacing

public void setPixelSpacing(int spacing)

getMinimumSize

public Dimension getMinimumSize()

Overrides:

getMinimumSize in class JComponent

setPreferredSizeProvider

public void setPreferredSizeProvider(PreferredSizeProvider provider)

sets the a provider that will provide the preferred size for this component. Value can be null. If the value is null then the preferred size will be computed by this component

Overrides:

setPreferredSizeProvider in class G2dComponent

Parameters:

provider -

getPreferredSizeLocal

public Dimension getPreferredSizeLocal()

Internal method that computes the preferred size;

Overrides:

getPreferredSizeLocal in class G2dComponent

Returns:

createPopupMenu

public void createPopupMenu()

Creates and initialized the internal popupmenu that is displayed when a right click event occurs on this object. The menu is only created once. Once created it is reused.

Overrides:

createPopupMenu in class G2dComponent

editProperties

public void editProperties()

This method is called when it is time to edit the properties of this component. Shows a dialog that allows the user to edit the specific properties.

Overrides:

editProperties in class G2dComponent

objectPopupMenu

public boolean objectPopupMenu(LocalPt pt,
 int modifiers)

Shows a popup menu at LocalPt pt if that point occurs within the boundaries of this Spacer panel. If the popup menu is displayed then true is returned signaling that this panel accepted the popup menu event. Otherwise false is returned.

Specified by:

objectPopupMenu in interface G2dPointerComponent

Overrides:

objectPopupMenu in class G2dComponent

Parameters:

pt - the point to place the popup menu;

modifiers - mouse modifiers that were recieved by the mouse adapter that may be usefull here.

Returns:

true if the object popup event was accepted and consumed otherwise false.

pointerOver

public void pointerOver(LocalPt pt)

Description copied from interface: G2dPointerComponent

Method called when the pointer is over a given point

Specified by:

pointerOver in interface G2dPointerComponent

Overrides:

pointerOver in class G2dComponent

Parameters:

pt - - the point in which the pointer is over

objectSelect

public boolean objectSelect(LocalPt pt,
 int modifiers)

Description copied from interface: G2dPointerComponent

Method called on left mouse click.

Specified by:

objectSelect in interface G2dPointerComponent

Parameters:

pt - the point to place the popup menu;

modifiers - mouse modifiers that were recieved by the mouse adapter that may be usefull here.

Returns:

true if the object select event was accepted and consumed otherwise false.
