Context menu/editing for some critical widgets (e.g range slider)

[miranov25]

Goal:

Widgets are not easy to modify - using parameters to much interaction.

TODO:

• Modification of the upper, lower, and bins for slider and ranges + title
• Number of the rows in multiselect ..
• ....
• to be extended

[miranov25]

Proposed layout of the slider and select widget:

• /home2/miranov/Documents/JIRA/PWGPP-485/RootInteractive_#236_extendedWidgets.odp

• 

[miranov25]

Composition of the several widgets not working well. Problem reported by @pl0xz0rz

1. Adding composed widgets with 2 row - layout was "destroyed"
2. Change of slider limits -s OEM side effect

[miranov25]

Based on @pl0xz0rz - there are limitation in bokeh layout - documented in doc pages. In case of more complex layout they recommend oun java script implementation.

Limitations The Bokeh layout system is not a completely generic, general-purpose layout engine. It intentionally sacrifices some capability in order to make common use cases and scenarios simple to express. Extremely nested layouts with many different sizing modes may yield undesirable results, either in terms of performance, or visual appearance. For such cases, it is recommended to use the methods in Embedding Bokeh Content along with your own custom HTML templates in order to take advantage of more sophisticated CSS layout possibilities.

Problem with the range slider - emulation with 2 spinners -upper and lower bound of variables 2 spinners to the same row: var min and var max

[miranov25]

Can we use global policy for the callback using parameters?

[miranov25]

2 composite widgets implemented.

• Range and slider are switchable/toggleble (#239)
• 2 spinners with exponential step (#240)

The suggestion from https://github.com/miranov25/RootInteractive/issues/236#issuecomment-1203739490 could not be implemented because there are some limitations with bokeh layouts. The 2 improvements from above cover a large part of the use cases.

[miranov25]

Parameter templates implemented () - not exactly the same functionality as in context menu but simplifying the declaration
