Using the FocuserInterface properties to add a new menu item

[peteasa]

Hi

I have a problem were there are a lot of Meade commands sent to my mount for an optional focuser that I do not have!

A while ago I created a simple button to disable the focus feature for an OAT / OAM mount that does not have the focus add on attachment - https://github.com/peteasa/indi/tree/OATFocusControl - see lx200_OpenAstroTech.cpp - Now the focus code has been updated in commit e086bab so I do not have direct access to the initFocuserProperties to add my button.

An improvement would be to actually remove the whole focus tab from the user interface if there was no focuser attached. However that change would require me to test the code with a focuser - and I do not have one of those.

Can you suggest a way to achieve what I want quite easily? The objective is for a mount that has no focuser not to poll with multiple Meade commands for an update to the focuser that does not exist. My simple button does this by returning from the OATUpdateFocuser() function if my button is in the disabled state in the same way that there is no polling if there is no movement.

You can use setLx200Capability to remove that. For example:

setLX200Capability(getLX200Capability() & ~LX200_HAS_FOCUS);

Thanks for your suggestion.

My existing button appears on the focus tab. That made sense to me because its the logical place to look. If I implement a button on a different tab then it is more difficult to use because the user might not know where to disable the focus feature. I thought that it might also be of use for a person who wishes to test the focuser that they have ie they could temporarily disable the focuser.

To implement your suggestion I would put the disable focus button on a different tab. When disabled I assume that the focus tab would disappear from the gui. To enable it the user would click the enable button and the focus tab would re-appear. I will test this out.

interesting few hours. caught up the code. loaded the latest indi release onto my Ubuntu machine and nothing worked!

ch: undefined symbol: _ZN4INDI16WeatherInterface12addParameterENSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEES6_ddd

built the latest driver (no changes) and replaced the release version with my latest build (/usr/bin/indi_lx200generic) was all I changed.

Suddenly everything burst into life!
