SetNextPlotDragDisable

[ozlb]

Set drag operations disable for the next plot. Call right before BeginPlot().

I understand what this does, but I don't understand why it's needed. Alternatively, the axis flags could be temporarily modified to include ImPlotAxisFlags_LockMin and ImPlotAxisFlags_LockMax. What particular problem are you trying to solve?

Assume that you want to customize with "widget" a plot
Assume that you want to interact with that "widget" and drag it
a) you need to be after BeginPlot() and before EndPlot() in order to get DrawList and to render it
b) drag of axis and query is inside BeginPlot so it's BEFORE the "widget" code so it will always win if you want to interlock "widget" drag operation with an active axis or query drag operation.
c) You need to lock axis, query and potentially all future "begin of drag operations", like the one mentioned from labels in Issue #89

Ok, that makes sense. Let me think on this and make sure there isn't a better solution. I can see potential headaches with the approach you described. Needing widget logic/input detection before BeginPlot, then SetNextPlotDragDisable conditioned on that logic, and then widget rendering after BeginPlot seems a bit burdensome. Perhaps it's time to properly implement custom a widget/tooltip system. Maybe via callbacks?

I’m with you that it’s not perfect. Callback could be a solution, you have a better vision of actual status and direction for future.
