Pan windows with mouse drag
« on: December 22, 2010, 12:54:59 am »
Could you give us the ability to pan the diagram windows (horizontally, vertically, and diagonally) with a mouse drag? E.g. Alt+Left Mouse Drag scrolls the window according to the direction of the mouse movement.

I know there is the Pan and Zoom window, but it would be much more convenient and faster if we could move around diagram windows by dragging in it directly, instead of having to move the mouse all the way over to this window, drag, and then move it back to modify the diagrams.   :-X Also, it would be great if this feature worked inside Visual Studio with the diagram window open inside Visual Studio - no need to rely on having the Pan and Zoom window being open (and thus unavailable for use inside Visual Studio).

It's already there, but it uses the middle mouse button (because the left button is used for selection).

I'm not sure which mode is default, but if you go to Tools | Options | Diagram there is an option 'Auto-pan with middle mouse button'.

This toggles between two scroll behaviors.

On - Click the middle mouse button to enter scroll mode, move the mouse and the further away from your click point the faster the window scrolls.  (See this in IE, Firefox and Opera)

Off - Hold the middle mouse button and move mouse like you have gripped the page.  Much like the 'Hand Tool' in Adobe Reader.

The behavior I was after was indeed similar to the way the 'Hand Tool' works in Adobe Reader. However, I find your implementation of this feature to be unreliable. It often happens that I get the 4-way arrow mouse cursor when I press the middle button, but then as soon as I drag, the cursor usually changes back to an arrow and the pan behavior does not work.  :-/

Could you give us the option to use a button other than the middle mouse button to pan drag with? I find using the scroll wheel for a drag operation is a pain, as the slightest wheel rotation will usually mess up the behavior being implemented with dragging.  :P  Perhaps allow the use of a modifier key (e.g. ALT, SHIFT, or CTRL, or even no modifier key at all) along with left mouse button drag to implement the pan operation.

I think FreeMind, although designed to work with mind maps, has the ideal interface for diagram navigation and control regarding this feature. Check it out.  8-)

You'll need to raise this formally as a feature request I think - but don't hold your breath on it being imlemented.
