More imgui widgets

[dromer]

Thought to collect some possible imgui widgets here:

https://github.com/cmdwtf/imgui_toggle - nice looking toggle switches - 0BSD
https://github.com/dalerank/imspinner - collection of animated spinner icons - MIT

Hmm, seems imgui_toggle breaks rules 1 and 6 since it contains more than one header and has several implementation files.

Unfortunate, since these do look quite nice.

Seems imspinner requires c++14 to work:

../../../dpf-widgets/opengl/DearImGuiSpinner/imspinner.h:150:24: error: use of ‘auto’ in lambda parameter declaration only available with ‘-std=c++14’ or ‘-std=gnu++14’

This is not going to scale if we keep adding more widgets to imgui stuff. this toggle and knob are quite essential, so I let them pass, just dont assume it is always the case.

Regarding C++14 requirement, yeah it is preferred we keep it C++11 so the code needs tweaking.
Other imgui based things are C++11, so let's not bump the requirement just for 1 single line of code.

Yeah agree, besides those spinners are not critical in any way just thought they looked cool ;)

Actually the imgui_toggle says it might be included in upstream imgui at some point: https://github.com/cmdwtf/imgui_toggle#future-considerations - will probably take a while, but by then we can clean it up from the inclusion perhaps.

Personally think the spinners are quite optional and we dont need them by default.

Out of the other widgets I have seen, only the nodes one would be ideal to have, but it needs some tweaking to work well for audio graph/patchbay purposes.

We can always manually include imgui based widgets on plugin gui code, alike done in master_me with the implot, see https://github.com/trummerschlunk/master_me/blob/master/plugin/widgets/Histogram.hpp

re node editor, which of these do you think is better?

• https://github.com/thedmd/imgui-node-editor - seems very extensible/customizable
• https://github.com/Nelarius/imnodes - much more simple/minimal

Very much leaning towards the second one.

Any other DPF patching plugin ideas floating already?

We were discussing sending midi notes from the UI and I came across: https://github.com/shric/midi/blob/master/src/Piano.cpp
