Constant Field Values

m_panelMode

public int m_panelMode

Flag if running as self-contained panel or as overlay of another container panel. Default is panel mode like, for example, in tree_view.

Constructor Detail

PuColorBarCanvas

public PuColorBarCanvas()

Construct a new PuColorBarCanvas.

Method Detail

setParent

public void setParent(PsUpdateIf parent)

Set parent of this panel which receives update events.

Parameters:

parent - parent of this panel

enableContextMenu

public void enableContextMenu(boolean bEnable)

Enable popup menu when right click into the canvas.

paint

public void paint(java.awt.Graphics g)

Paints this canvas.

Most applications that subclass Canvas should override this method in order to perform some useful operation (typically, custom painting of the canvas). The default operation is simply to clear the canvas. Applications that override this method need not call super.paint(g).

Overrides:

paint in class java.awt.Canvas

Parameters:

g - the specified Graphics context

Version:

11.11.2006, 1.00 revised (mn) Moved to subclass PuColorBarCanvas.

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent mouseEvent)

Invoked when the mouse button has been clicked (pressed and released) on a component.

Specified by:

mouseClicked in interface java.awt.event.MouseListener

mousePressed

public void mousePressed(java.awt.event.MouseEvent mouseEvent)

Invoked when a mouse button has been pressed on a component.

Specified by:

mousePressed in interface java.awt.event.MouseListener

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent mouseEvent)

Invoked when a mouse button is pressed on a component and then dragged. MOUSE_DRAGGED events will continue to be delivered to the component where the drag originated until the mouse button is released (regardless of whether the mouse position is within the bounds of the component).

Due to platform-dependent Drag-and-Drop implementations, MOUSE_DRAGGED events may not be delivered during a native Drag-and-Drop operation.

Specified by:

mouseDragged in interface java.awt.event.MouseMotionListener

mouseMoved

public void mouseMoved(java.awt.event.MouseEvent mouseEvent)

Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.

Specified by:

mouseMoved in interface java.awt.event.MouseMotionListener

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent mouseEvent)

Invoked when a mouse button has been released on a component.

Specified by:

mouseReleased in interface java.awt.event.MouseListener

mouseEntered

public void mouseEntered(java.awt.event.MouseEvent mouseEvent)

Invoked when the mouse enters a component.

Specified by:

mouseEntered in interface java.awt.event.MouseListener

mouseExited

public void mouseExited(java.awt.event.MouseEvent mouseEvent)

Invoked when the mouse exits a component.

Specified by:

mouseExited in interface java.awt.event.MouseListener

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

Invoked when an action occurs.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

getPanelMode

public int getPanelMode()

Get flag if running as self-contained panel or as overlay of another container panel.

setPanelMode

public void setPanelMode(int panelMode)

Set flag if running as self-contained panel or as overlay of another container panel. Default is panel mode like, for example, in tree_view.

Specified by:

setPanelMode in interface PvDisplayOverlayIf

getPreferredSize

public java.awt.Dimension getPreferredSize()

Gets the preferred size of this component.

Specified by:

getPreferredSize in interface PvDisplayOverlayIf

Overrides:

getPreferredSize in class java.awt.Component

Returns:

a dimension object indicating this component's preferred size

setDisplayComponent

public void setDisplayComponent(java.awt.Component panel)

Set panel of of this container which provides graphics context.

Specified by:

setDisplayComponent in interface PvDisplayOverlayIf

paintOverlay

public void paintOverlay(java.awt.Graphics g,
                         int xInset,
                         int yInset,
                         int width,
                         int height)

Draw overlay in JavaView display.

Specified by:
