Lock Axis, No tilt

[fatman]

Hello,

How can I programmatically lock the axis so that the user cannot use the right button to tilt the globe in my application?

Thanks,
Matt

Do a search in the SDK for:
RIGHT_PRESS
DragSelectEvent
pitch

../doc/gov/nasa/worldwind/event/DragSelectEvent.html

..\src\gov\nasa\worldwind\View.java
void setPitch(Angle pitch);

gov.nasa.worldwind.animation.Animator;
gov.nasa.worldwind.awt.ViewInputHandler;

I set my pitch (from horizontal) like this:
view.setPitch(Angle.fromDegrees(90 - dPitch));

There should several ways to disable the user from changing the pitch.
I have never done that but at least gave you places to look.

the easiest way is probably to add this line in your worldwind canvas:


getView().getViewPropertyLimits().setPit chLimits(Angle.ZERO, Angle.ZERO);

limits the pitch to look straight down onto the earth. but you can set it to any Angle you want.

Register a mouse handler with WW's input handler and mark consumed the events you don't want handled. Look at the LineBuilder example to see how to install your mouse handler.

Worked like a charm! Thank you all for your replies!

Cool, what a timely thread - I'm using this solution also. Thanks Matt, thanks Straider.

Double thanks! While I took the quick and lazy solution to my original problem, this bit of direction pushed me in the right direction for another task - how to use a button to toggle mouse navigation on and off!

I am trying to create a button that toggles a generic view. (For example profile view or top down view.) I get a 'getView() is undefined' error when I try the command line above.

help please? I've tried setView() too. I'm really just stabbing in the dark now cuz none of the commands from the library I found seem to work anymore.

Figured it out!

BasicOrbitView view = (BasicOrbitView) wwjPanel.getWwd().getView();
view.setZoom(8e4);
view.setPitch(Angle.fromDegrees(0));

Good you got the code to set the pitch.
From post #2:
I set my pitch (from horizontal) like this:
view.setPitch(Angle.fromDegrees(90 - dPitch));

I should have put this line in also for those that are not familiar:
BasicOrbitView view = (BasicOrbitView) wwjPanel.getWwd().getView();
