Roassal should offer a proper scrolling mechanism

For any visualisation that is larger than the screen, you immediately get lost in Roassal.
Furthermore, the current dragging style does not scale for visualizations that are
much larger on one dimension than the screen.

We need a mechanism that helps us:
- get an idea of where we are (and how much is left outside the current view)
- have an easy way to actually scroll through a larger space

Please make one of those scroll methods "holding the space bar" (which optionally display
a hand) that grabs and drags the View background.  This is the same as many graphics
programs including at least Photoshop and Paint.net.   I find it difficult to live
without it :)

Indeed. 

This type of navigation is similar to what exists right now, but better. Here is why:
- Right now, dragging can have two distinct meanings depending on where you are. Especially,
if the element is small, you do not know for certain if you will drag the element,
or if you will scroll through the view
- Having a pseudo-mode (e.g., pressing space) will clarify the situation significantly.

This type of navigation should not disappear even if we add some other means.

I agree with you Doru. What I had in mind originally, is to have a mini-map. 
Scrollbar should indeed be offered. 

@Ben : I am not familiar with this "holding the space bar". Is there such a think,
in let's say Omnigraffle?

Not in Omnigraffle, but more in 3d scene tools :).

This evening I will meet some friends who has autocad, I will ask how the scrolling
is handled there.

Any update on this?

Not much so far. It should not be that difficult however.
But is the minimap not enough? It is pretty cool

A Recurrent issue...

Hi, here comes a scroll bar and a scroll pad to have a scalable navigation in the view.
Try out examples in RTScrollBarBuilderExamples.

This has been in Roassal for a while already
