Hi all,

 

I am working on a way to draw a line on an intensity graph in CSS BOY. I have a Jython script which can track the image co-ordinates.

Now, I need to have a way by which I can capture the mouse events on the intensity graph like click and release.

 

I am a novice in writing Jython scripts. I came across this thread (https://epics.anl.gov/tech-talk/2017/msg00775.php) and dropped the idea of using pynput package.

 

I have created a MouseListener to listen to pressed event, but it seems I cannot get the mouse events. Have I missed anything?

 

This is my script:

 

from org.csstudio.opibuilder.scriptUtil import PVUtil, ConsoleUtil

from org.csstudio.swt.widgets.figures.IntensityGraphFigure import IPixelInfoProvider

 

from org.eclipse.draw2d import MouseEvent

from org.eclipse.draw2d import MouseListener

 

from org.eclipse.ui import PlatformUI

from org.eclipse.swt.events import MouseWheelListener

 

class MyPixelInfoProvider(IPixelInfoProvider):

                #### Provide custom information for each pixel.

                def getPixelInfo(self, xIndex, yIndex, xCoordinate, yCoordinate, pixelValue):

                                result = "My index is (" + str(xIndex) + ", " + str(yIndex) + " )"

                                ConsoleUtil.writeInfo(result)

                                return result

widget.getFigure().addPixelInfoProvider(MyPixelInfoProvider())

 

class MyListener2(MouseListener):

                def mousePressed(self, event):

                                ConsoleUtil.writeInfo("down")

 

my_listener2 = MyListener2()

widget.getFigure().addMouseListener(my_listener2)

 

Many thanks in advance.

 

Kind Regards,
