[FEATURE] Control over the Toolbar icons collapse

[ofir-frd]

Problem description

The Toolbar collapses icons into a 3 dots button (before and after).
This behavior confuses users.
Also, in some cases, the figure is big enough to accommodate all icons but the collapse still occurs.

Feature description

A boolean property to disable the collapse feature of the Toolbar.
For example:
Toolbar.collapse = True/False

Potential alternatives

Set a number for "must show" icons.
For Example:
Toolbar.number_of_icons = int

Additional information

No response

Also, in some cases, the figure is big enough to accommodate all icons but the collapse still occurs.

This looks like a bug. I would recommend trying out bokeh 3.0-rc if you can. There were a lot of changes, fixes and other improvements to toolbars in this release, so it's likely already fixed. Otherwise please submit a minimal reproducible example for us to reproduce this, and the version of bokeh you use.

[mattpap]

Toolbar.number_of_icons = int

In bokeh 3.1 there will be support for customizable tool buttons, see #8153.

Thank you @mattpap !
I will take a look into bokeh 3.0-rc.

@ofir-frd - If I retain the bokeh logo, the collapse does not happen. I, too, do not like the collapse, and I think it would be confusing for users of my app.

@davidforel there's not really any information to go on in your statement, e.g. are you talking about recent versions of Bokeh, or the versions from when this relatively old issue was opened? Did you attempt to try the Toolbar.number_of_icons described above? What are the specific circumstances that trigger a collapse? Do you have a MRE that can be run for investigation? Does this happen in all browsers or just one? What I would strongly suggest is to open a brand-new bug-report [1] issue with all the information requested in the new issue template. Link to this discussion, which we would then close in favor or a detailed issue.

[1] Assuming you see the issue described above by @mattpap still occurring (in latest releases), or if the number_of_icons property does not work as expected (in latest releases).

Adding NEEDS MORE INFO here in any case. There is nothing we can do with this issue as it stands, and I will close it soon regardless if it does not become more actionable (or replaced by a newer detailed issue)

[davidforel]

@bryevdv - You are quick! Well, I am a noob, so I can't give you everything you want [ MRE = Meals Ready to Eat ? ]. Bokeh version is 3.3.0, browser is Firefox, OpSys is WIn10. I am writing about Ofir's post in [ https://discourse.bokeh.org/t/toolbar-button-collapse-on-small-figure-size/9611 ] here because this seems to be the follow-up page. I am not concerned with the size of my plot forcing the toolbar collapse (my plot is pretty good size), just the fact that the collapse occurred at all. As @ofir-frd wrote on the referenced page, I would like to set a flag so the collapse cannot happen. I don't think it is cool that I would have to specify the number of tools to avoid toolbar collapse. Thank you for your patience.

Hi @davidforel MRE stands for Minimal Reproducible Example i.e. code we can take and run, without any modification, to reproduce what you are seeing, to make sure everyone is actually on the same page.

[bryevdv]

@davidforel @ofir-frd we do need a complete script to reproduce the issue, as well as any instructions that go along to make the problem show up. Otherwise, this will have to be closed as norepro

[bryevdv]

@mattpap what do you want to do with this issue? There's not code given here or in the Discourse issue, so I am inclined to close it.

[mattpap]

There are issues with the current approach, which I'm addressing in PR #13571. I also plan to add support for a variant of a multi-line toolbar (either add support for wrapping or grid tool button layout or both).
