Diagonal scrolling with arrow keys

[jacke]

As I always have used the arrow keys for scrolling, I really miss the way this works in TTD. I want to be able to scroll diagonal by pressing two arrow keys.
And scrolling faster with shift-key does behave strange, you have to press the shift key first and then the arrow key to make it scroll faster, which is very annoying.

I saw a feature request for this at source forge, but there were no comments given.

Just wonder if there are any plans to "fix" this ?

I would like to see this improvement too.

In TTD I always "scroll" with the help of the "C-key" (center on the mousecursor).
This way you can scroll in any direction and nearly at any speed. Just move the cursor into the direction dat you want to scroll, and press C, once or mutiple times. The screen gets redrawn with the new center at the position of the mousecursor.
If you move the mousecursor at the edge of the screen you'll scroll fast and if you place it in the corner of the screen you'l scroll diagonally.

Oh, didn't know you could do this, have to try

Hello,

Yesterday, late in the night, I added a little quick patch on sourgeforge.net that allows to use the middle button of your mouse instead of the C key for the same result...

Could you try it ? (I joined the patch to this post)

(The code isn't finished in the sense it is only for windows for the moment, and there's no way to turn it off, but if you guys like it, I could finish the implementation...)

I'll try it if you make it work in linux

you could be that again if you are more active. We removed the people, who didn't submit anything for a long while and the current developers didn't even know

The problem for the linux version is that I don't seem able to compile using SDL correctly (Openttd tries to lauch but exits directly without any error...)
I think I could do the code blindly, but then it would be very random as a result (I think the code to be changed is in the the "case SDL_MOUSEBUTTONDOWN and SDL_MOUSEBUTTONUP" section, it only needs to set _middle_button_down = true and _middle_button_clicked = true in the event of a SDL_BUTTON_MIDDLE, it is quite straightforward... but I have temporarly no access to my dev pc ...

I Hope I can do it this evening...

-- edit --
Here is an update to the patch, it *should* now work with sdl (and linux...), but I can't give any warranty, as I am not able to test it under linux, not even with sdl under windows...

Happy testing, and any comment would be welcome
(I already have some improvements on mind)

Diagonal arrow scrolling is in SVN by the way (at least for SDL, I don't know about Win32).

Great
I just tried and it worked fine, but there is one little thing with scrolling that still annoys me...
When you press an arrow-key + shift-key to scroll faster, and then release the shift-key without releasing the arrow-key, the scrolling stops. You have to release the arrow-key and press it again to continue scrolling, which I think shouldn't be needed.
Did you get me ?
