Summary

This PR modifies ScrollArea and Plot to disable their interactions when the UI is disabled.

Changes

  • Interaction with ScrollArea in egui is disabled when the UI is disabled.
  • Interaction with Plot in egui_plot is disabled when the UI is disabled.
  • These changes ensure that ScrollArea and Plot behave consistently with the rest of the UI, preventing them from responding to user input when the UI is in a disabled state.

Impact

This PR enhances the consistency of egui's UI behavior by ensuring that all elements, including ScrollArea and Plot, respect the UI's disabled state. This prevents unexpected interactions when the UI is disabled.

Closes #4341

If disabled means that you cannot change widget properties (like entering text in text fields), then scroll area should not respect this setting, because it does not have properties that reflects application data. Imagine a read-only table widget which you cannot scroll because it is non-editable. I think, that is not what you want.

In mainstream UI frameworks like Qt and MFC, disabling a parent widget results in all child widgets becoming non-interactive. This includes the scroll bars of the child widgets.

Instead of relying on the disabled state of the scroll area, a read-only table should be implemented as an inherent feature of the table itself. This approach is more direct and explicit, and it avoids potential issues that could arise from disabling the scroll area.
