Mouse wheel scrolling in mouse-over panel

[VolkerWippel]

Hi
Several programs (Firefox,...) do it already: Scrolling with the mouse-wheel in a not active window which has the mouse over it. So I keep the view of the selected files in the left panel, and can quickly take a look at the files in the righth panel without changing the active panel (running the risk of loosing my selection if missing the right key).

Scrolling of standard listboxes is not handled by Total Commander itself, but by Windows. It seems to depend on the mouse driver whether it sends the scroll messages to the window under the cursor, or the active window.

OK. But it must work somehow, since in Firefox I can scroll my bookmarks and the pages depending over which panel the mouse is positioned (not clicked). On the same computer this does not work in TotCmd.

VolkerWippel,
There are a lot of tools that allow scrolling windows under cursor instead of active ones, try KatMouse or AlwaysMouseWheel.

Thank you for the links.

Still, with my mouse driver and without additional tools some programs show this convenient behaviour (the latest FreeCommander does as well). So it would be nice if TotCmd would too.

But even without: TotCmd is a great tool I install first after computer setup, and I start immediately after logging in every single time!

After test:

Totalcmd 8.01~8.51b2 64bit can scrolling with the mouse-wheel in a not active window.

But Totalcmd 8.01~8.52b 32bit not works.

Which tool did you use? Maybe it's a 64-bit tool which doesn't work with 32-bit programs?

Totalcmd 8.01~8.51b2 64bit can scrolling with the mouse-wheel in a not active window.

But Totalcmd 8.01~8.52b 32bit not works.

I can confirm this.

Windows 7 x64, Logitech Setpoint Dirver Version 5.33.14.

And the wheel works in other 32bit applications like Devenv.exe (Microsoft Visual Studio 2013) independent from the focused control (wheel events are send to the window under the mouse cursor).
Only the 32 Bit Delphi TC seems to capture the mouse wheel event inside the focused window.
If i move the mouse from the focused TC panel outside the application window, the focused file panel still reacts on wheel events.

Holger

Interesting, it seems that Lazarus really scrolls panel under mouse cursor even if it is inactive. But it works only if TC has focus (and it is logical because only in such case it receives mouse messages w/o hook).
