how to create a dynamic form?

fatcat1206

Hi All

I'd like to create a dynamic form, just like the property form of "vpwl" voltage source in the "analogLib".

In my form, I also has a integer field like "Number of pairs of points" to define how many groups of string fields I would like to have later on; this group of fields can be understand as the "Time x" and "Voltage x" pairs in the "vpwl" property form.

In the callback functions of the integer field, I have changed the form->fields value accordingly, to "add" or "remove" the corresponding fields groups in the list of fields

Although the form->fields value has been changed, the form still remains the same.

Does anyone know how to update the form, or make a dynamic form

P.S when one field is removed from the form, I want the content in that field is still kept; so when this form has been brought back later, the content is still there.

Best Regards

  • Yi,

    Here's one example of doing such a thing: 

    Another possibility would be to control the visibility of fields - this way you could keep the content of the fields once you've added them, but use the ->invisible property on the field to make it so it's not shown. Alternatively you can have callbacks on the fields to store away the values in another structure, or collect this info just before you delete the filed. Lots of ways to skin a cat.
