Qodly Studio for 4D: Dynamic User Interfaces with Page States

With 4D 20 R6, Qodly Studio for 4D introduced an exciting new feature: Page States. Perhaps you’ve already come across our previous post, but let’s explore what makes this feature so valuable for dynamic UIs.

Imagine UIs that adapt instantly to different user steps or contexts.

Here are some common use cases where Page States shine:

  • Enable or disable components based on user actions (e.g., activate the “Save” button only when all mandatory fields are filled).
  • Switch between light and dark modes with a simple toggle.
  • Restrict access to actions (read, update, etc.) based on user privileges.
