We are going to have a demonstration of our application in few hours , Is there any way so that moving and resizing of everything can be disabled just for the cause of demonstration? In simple words is there any presentation mode in qlikview?
If your audience are technical they may ask you to demo your application in the way that it would be seen by their users, which will probably be in a client-server environment instead of using the developer software.
If you are showing the application through the server you can set not to have objects be resized or moved under System > Setup > Server > Documents > Objects > Allow Moving and Sizing Objects
If you are showing the application using the developer software, I think the Layout > Allow Move / Resize checkboxes have to be unticked on each object in turn.
