A Graphical User Interface

• Use Alpine to make a graphical editor for plate layouts
  • What treatment is applied to each cell
  • Personal details
• Use CSS flexbox layout to create two-column page
• handwritten.html creates everything manually
• Shared data stored in x-data attribute of enclosing div (the row)
  • treatments is available treatments (including emptry string for "none")
  • current is currently-selected treatment
  • data is the plate data keyed by row/column identifier
• Selectors are radio buttons
  • Share the same name to make them a group (only one can be selected at a time)
  • Value is self-explanatory
  • x-model property tells Alpine what to assign the value to
  • Writing these by hand was annoying
• Plate is a table
  • Each cell's x-text property tells Alpine where to get data to display
  • x-on:click is the action to take when the cell is clicked
• Note: do not change cell values directly
  • MVC: controller updates the model, view reflects the model
• Templating
  • Template in templates/design_simple.html
  • For now, use render.py to test it out
  • Templated version is 51 lines instead of 72, but will automatically expand as we go to larger plates
• Now add dosages in templates/design_dosages.html
  • Invariant: (no treatment and no dosage) or (some treatment and some dosage)
  • I.e., cannot have a treatment with no dosage, and cannot have a dosage if no treatment selected
  • Initialize to "no treatment" (empty string) and "no dosage" (also empty string)
    • But no radio button for "no dosage" case
  • When a treatment is first selected, the dosage is set to the minimum dosage
  • Use $watch to watch for changes to the current_treatment and current_dosage variables
  • Update the other state elements accordingly
  • Again, the controller updates the model, the view displays its current state
