New Widget: Recording duration

[ronso0]

I'd like to introduce a simple label widget that displays the duration of a running recording in the skin, apart from Recording section in Library.
A while ago I filed a wishlist bug but noone with more C++ experience & spare time picked this up so far.
Newbie that I am, I couldn't make something from the hints @daschuer posted, so I tried to learn from WTime widget (simple widget) and dlgrecording.cpp (queries recordingmanager for recDurationString). Right now I fail to set up the header file correctly.
Is this approach promising at all? If yes, I'd appreciate very much if someone could explain that header file.

For your current approach, you need to pass the RecordingManager here:

mixxx/src/mixxx.cpp

Line 332 in 2b26c46

if (!(m_pWidgetParent = m_pSkinLoader->loadDefaultSkin(this, m_pKeyboard,

and here

mixxx/src/skin/skinloader.cpp

Line 127 in 93bc889

LegacySkinParser legacy(m_pConfig, pKeyboard, pPlayerManager,

similar to m_pVCManager and WSpinny

In general, I would prefer a ControlObject based solution passing the unformatted values around and format them at the using element. This would for example also allow to access the values from scripts.
However this is somwhat more work.

Thanks for your help! I will try that tonight.

Okay, I see the advantage. Are there plans to use scripts for something other than controllers, skin maybe?
I recall how long it took me to work on brake/softStart so I took the easier appearing way here...

Woohoo, it's working! Can't tell if the code okay, as well.
To test it, I put it behind Rec button in Tango.

Last recordings duration is visible for a second when new recording is started.
Seconds seem to flip over irregularly, like in Library > Recording.

Now that I tried it a few times, I think it might be handy to have a all-in-one widget, actually a dynamic button that handles [Recording],toggle_recording, displays [custom_text][recording duration] when recording and would clear when the recording is stopped. Text could be defined with , and , that way the button could be designed for available space or even translated.
But this won't happen in this PR, if I can do it at all.

...messed this up with local compile. F#*!
I'll close this and start over. Sorry!
