Synchronizing the views of 2 WolrdWindows

[mostafa_fahim]

Hi all, I want to open 2 worldwindows say A and B. I need to deactivate the controls of B and get the controls (SelectionListener, MouseListener, MouseWheelListeners and KeyListeners) of A to control both views of A and B.. I tried editing in the AWTInputHandler and ViewControlsSelectListener and managed to do so but after a while a lag happens and both A & B become out of sync.. Any help?

Thank You

It's good you got the concept of what you are trying to accomplish worked out.
I don't recall an issue like this before.

At first glance it could be a memory leak since you don't seem to be adding a large amount of data. Try using the Task Manager to track that down.

edit: or try this, I don't use it except tinkering with the examples

One aspect of performance can be seen by toggling that on, then watching the metrics panel to see the frame rate achieved.

Running many instances of a WWJ app or different WWJ apps isn't usually a problem.

Concept to get something to work is fairly easy.

Error handling involves a considerable amount of work.

Optimizing the code seems to be the most work.

Did you review the multi-window examples?

All you should need to do is not add your controls layer to B, then have A respond by controlling both A & B. I don't see that you'd have to do anything with AWTInputHandler. You would probably have to modify ViewControlsLayer to meet your needs.

The viewControlsLayer modification will enable me to control both by the buttons at the left bottom corner only. This is one part but also I need to control both by the mouseWheel, mouse clicks and mouseMotion.
Actually I managed to do it by creating 2 windows like in multiFrame.java example and do so x.setView(y.getView());

Thank You for your help
