Hi everyone,

I’m trying to build a search filter similar to the Ctrl + F feature in apps like Chrome    

I created a non-visual object that initializes data such as the DataWindow that i want to search and the parent window.
Then, I export the DataWindow data as JSON and search the JSON string to find the matching line and column, returning the column name and row number.

Everything works fine, but I have one issue:
I want the search event to trigger while typing, just like in other applications.
(The JSON export happens only once, when the filter window opens.)

The problem is that I can’t find any event that fires properly while typing in a SingleLineEdit control.
I’ve tried key, modified,  ItemChanged and several pbm_ events  none of them work as I need.

The only event that works is using the Other event, but it causes a strange issue:
every time I press a key, the input language switches to English automatically.

Has anyone faced this before or found a workaround?
I’d prefer not to use a dummy DataWindow just to capture typing.

Thanks in advance!
