Hi, I want to keep track of the cursor position in a BasicTextField.
Everything works fine except, when I tap/click somewhere inside the TextField text, it (for sure) changes the position of the cursor,
but as no text change or layout change is happening to the TextField content, I cannot update my cursor position.
I have TextLayoutResult as a remembered state to get the new cursor rect via
TextLayoutResult.getCursorRect(textFieldValue.selection.end.coerceAtMost(layoutInput.text.length))
how can I get the cursor rect when I change it via "just clicking somewhere else" inside the TextFields text?

Use the TextFieldValue overload to get the position of the cursor, then use the layout result to calculate its coordinates

hmmm, could you elaborate a bit more, please?
Not totally clear what you mean.
(a) if I "click" somewhere in the text, NO .clickable(...) or .onClick() neither .pointerInput(Unit) { ... } will be called.
(b) IF I somehow manage to get a click "recognized", how can I get the cursor rect out of the TextFieldValue ???

[Dirk Hoffmann]

ok, think you meant TextLayoutResult (and not TextFieldValue) ... so (b) would be an ugly line like:

val cursorRect = textLayoutResult.value?.multiParagraph?.getCursorRect(textFieldValue.selection.end.coerceAtMost(textLayoutResult.value?.multiParagraph?.intrinsics?.annotatedString?.text?.length ?: 0).coerceAtLeast(0)) ?: Rect.Zero
            println("cursorRect in onClick: $cursorRect")

leaves me with problem (a) I just don't get any click/tab working for BasicTextField. Any ideas on that?? @Zach Klippenstein (he/him) [MOD]

If you want to track any time the cursor changes, use TextFieldValue and observe it for selection changes. If you specifically only want to track clicks, then use TextFieldValue and a pointerInput gesture to peek at pointer events.
