Just noticed after some work in Blender that Freecad might actually have-why not))-some similar feature that Blender has.
When entering a value/parameter into object parameter field-left hand bar- one should either enter the number or move mouse scroll wheel to increase/decrease it.
You can use mouse scroll wheel to change the value.
In Blender you can also place mouse cursor within the filed and move the mouse left/right to alter the value.
FreeCAD uses Qt toolkit and more or less the standard behavior it provides for widgets. Custom behavior (like the one you described) would likely be possible to implement. But i could imagine motivation to do that is low.
And another issue: why the graphicall object being edited in a numerical field /eg. wall parameters/ can not be altered real time in 3D window?
This is crucial for fast, effective modelling.
Historically there wasn't much development and i guess interest in this area. Likely due to the fact FreeCAD and Blender are a different thing. In Blender it would be hard to imagine changing meshes with parameters. On the other hand in FreeCAD it's all about changing parameters to change the geometry. In the future likely users will be able to interact with geometry directly in 3D View. And by doing that change the underlying parameters. With the advancements of surface related capabilities in FreeCAD there will for sure be more demand for that. But for now this wasn't a crucial part of FreeCAD workflow. In addition FreeCAD developers don't have such close relation with FreeCAD viewport ATM. Compared to Blender developers. We use Coin3D and the capabilities it provides. In Blender everything is/was custom made and they invest much more effort in this area. For example they develop things like Eevee viewport. It is unrealistic to expect FreeCAD developers would do something like that anytime soon.
