Dragging a big image in a smaller "canvas"

[kortezzzz]

Hi,

My question is about a very simple feature you'll probably find in the android\web world.
Lets say we've determined an image "canvas" in FS with a size of 200X200 pxls. Now, we are loading in to it a 400X400 pxls image. I need a mouse feature that allows me to drag to the left\right\down\up to see the hidden parts of the image. Does anyone knows how to do it?

I have done this before in a piano roll.
I think you will best start by hooking it up to sliders-
imo start there mate,
and then you can use the mouse over on the image itself
I can up the piano roll if you like, actually- here 'tis->

I think this is for 3081
The view scroll is the slider on the left of grid

Thanks guys, those are great examples and a great starting points, but I ment scrolling without extra sliders. Only with mouse cursor. I mean like every time you point the image and push the cursor+left button pressed, the whole image moves to the dragged direction.

Here is a very basic hand tool. No boundary checking etc., just plain click&drag. Can you take it from there?

Wow, Martin! You've evolved a lot since the early days. Keep it going!

I corrected a few bits, used syntax and style according to the style guide and added boundary checks. Now some people in the past have reacted strangely, so if you don't want me to correct your code, just say so. It will spare me the work, and I won't mind it.

Works real nice Tulamide.

Why should anyone refuse to such a possitive tribute? If someone already decided to shares something, what's the point in refusing to customizing it or even improving it? that's one of the forum's best benefits
Please guys, don't push us into that dirrection.

Thanks!!!
