Wish: Define inputs in MultiInputForm++ as required

[andydandy74]

Hi Mostapha, It would be great if we could define inputs as required. Right now it's up to the script to evaluate the input data downstream and bring the whole affair to a fairly graceful ending in case the user hasn't filled out the form correctly. Basically I am suggesting the following:

• Add an additional boolean input "IsRequired" to all relevant UI input nodes (dropdown, listview, textbox etc.)
• When pressing OK in the form the MultiInputForm class will cycle through all required inputs and check whether the user has entered a value
• If all checks pass, the graph continues
• Otherwise the class shows a message box with a message like:

  The following fields are required: 
  [List of labels of required fields without values]
  Please fill them out before continuing or press Cancel.

  Now that you've found a smart solution for the disabled inputs, I think it would be safe to think about adding new inputs to existing nodes again.

Hi Andreas, Thanks for you message. That's a very interesting thought! I'm trying to figure out the most efficient way to decide wether an input is "valid" or not (because the condition isn't necessarilly the same for all input types .. some will be blank, some will be null etc.). I'll definitely explore this and let you know :)
