Marvin Space - Monitor

Hello,

I want to add a distance monitor to a MarvinSpace canvas.  I've seen it mentioned in the GUI usage guide but I can't see any documentation on how to add these to a basic canvas.

Does anyone have an example of this or could point me to the neccessary documentation?

Thanks,

Sam 

Hi Sam,

 

1 Clikk the distance icon in the toolbar (leftmost button). 

2 Then click one atom of you structure, it becomes pink when selected.

3 Then click the second atom, the distance monitor is displayed, connecting the two selected atoms.

4 Optionally, you can drag the distance label away in a better position.

 

Does this help?

Hello Miklos,

Thank you for your reply.

The Marvin Space window I have implemented is very basic (it looks similar in funcationality to this example http://www.chemaxon.com/marvin/examples/applets/space/embed.html)

i.e. I don't even have a toolbar to accompany my window.

Do you know how I can add on to the MSpace window?

Many thanks,

Sam

Hi,

I hope this helps:

// Retrieve a component (the first component in the first cell)
            GraphicComponent gc1 = graphicScene.getGraphicComponent( 0, 0 );
            // Create a distance monitor
            Monitor monitor = new DistanceMonitor();
            // Associate the monitor with the component
            gc1.associate(monitor);
            // Select the first, and the third atom of the component
            monitor.selectItem(new ComponentElement(gc1,MoleculeComponent.COMPONENT_TYPE_ATOM,  2, 1));
            monitor.selectItem(new ComponentElement(gc1, MoleculeComponent.COMPONENT_TYPE_ATOM, 2, 3));

             // Add the monitor to the scene
            graphicScene.addComponent( monitor );
            monitor.select();
            // Now, create a label for the monitor
            chemaxon.marvin.space.monitor.Label label = new chemaxon.marvin.space.monitor.Label();
            label.selectItem(monitor);
            label.setRelativeXCoordinate( graphicScene.getCellLeft() );
            label.setRelativeYCoordinate( graphicScene.getCellButtom() );
            monitor.unSelect();
            // Add label to scene too.
            graphicScene.addComponent( label );
            // Associate the label with the monitor
            monitor.associate( label );
            // Do the measurement
            ((DistanceMonitor)monitor).measurement();
