TableView InputField live Highlighting (REGEX)

[NotYourFan]

Hey,

i have a tableView with setData, data etc.
The InputField with data and setData works fine and perfect.

Now I want to make a "live Highlighting" thoughts with regex.

Example:

• My regex accepted only numbers
• The InputField has a red background color (because its not filled)

now I want to:

• if I input the first number (9) --> green background
• If I Input a Number an then a letter (9a) --> when I input 9 --> green background --> after input a --> red background
  ...
  ...
  so I want a live highlighting ... do you have any ideas ?

Combine signal from your "InputField" as user types (e.g. textChanged) with QValidator which has states Invalid/Intermediate/Acceptable?
