Total Commander

In case if the main button bar has paths containing environment variables:

[ButtonBar]
button=%MYVAR%\blabla.ico

and the button bar is changed before the WM_SETTINGCHANGE, then needs to manually open Button Bar dialog and press OK to trigger button bar icons reload. The point is the `MYVAR` here can change externally and TC does not reload the icons by the WM_SETTINGCHANGE message.

I think TC should reload the button bar because the button bar paths can contain environment variables.

This is intentional, otherwise caching bar files would be impossible.

To force a reload, simply go to Configuration - Change button bar and click OK.

No need to change, it reloads even if just press OK. But why not does the same on WM_SETTINGCHANGE?

WM_SETTINGCHANGE can be quite frequent. Reloading the button bar can be very slow when there are many programs with individual icons, so it would cause a huge slowdown.

Agree, furthermore the reloading would take effect only on the current button bar. All other button bars would remain unchanged which would be inconsistent.
