248/252 Improve RIT and Bandwidth adjustment using mouse wheel

[w7sst]

Improve RIT and Bandwidth adjustment using mouse wheel.

• change mouse wheel RIT movement to 50Hz/step Change mouse wheel RIT movement to +/- 50Hz per step #248
• Adjust receive Bandwidth using Cntl-key and mouse wheel Bandwidth adjustment using Cntl-key with mouse wheel #252

This change has been applied in many forks over time. However, none of them had detected or fixed the problem of multiple events being handled for a single mouse wheel click/movement. By setting Handled=true, only one event is handled. This was important for smooth operation of Bandwidth control using the Cntl-key.

If I remember correctly, I set a smaller RIT step for mouse wheel on purpose to be able to adjust more easily. I actually hacked a mouse to make it a "real VFO" in an enclosure and a knob, and and frequency changes with the knob were too abrupt. May I suggest to allow the user to set this step in (another) setting in the ini file ? ;-)

Thank you - good suggestion. I have implemented this as you suggested. See #248 for additional details.

@f6fvy ,
Here is a link for this build, 1.84-pr4.

@f6fvy, first question...

Should we let the RitStepIncr setting apply to mouse wheel movements only? I currently have them both tied to the same override setting. Do you see an use case where the use would want separate control between arrow keys and mouse wheel?

@f6fvy, second question...

Should I set the default value to 30 or 25, instead of 50Hz/step?

In your original comment, you implied how you wanted a smaller value for fine control.

I'm wondering what a good default value would be. Initially I was matching the Up/Down arrow key movement. However, this does change from the previous release's behavior, which I think was 150Hz/step (50Hz/step times 3 events firing per mouse detent movement).

1/ I don't think necessary to have two different settings because most of the time the user is used to using either the keys or the mouse. Once the method is selected, the user can adjust the step if the default doesn't suit him/her.

2/ The default value sounds good to me after testing your pre release 4. But other testers may have a different opinion.
