Question

Is there an `OnPointerEvent` common API for Desktop and Android

Javier · Answer

`PointerEventType` is common but the modifier is missing

Javier · Answer

Found ``` pointerInput key1 = Unit block = detectTapGestures onTap = offset gt ```

Javier · Answer

Having a common `detectTapGestures` modifier should be great

Adam Powell · Answer

What is the use case that isn t met by ` clickable` We didn t find much there to counterbalance people using a tap input only modifier when `clickable` would be more appropriate and then creating a poor experience with regard to missing visual feedback or keyboard focus behavior

Adam Powell · Answer

and imo the android studio autocomplete behavior that adds in explicit `key1 =` and `block =` params in calls like that leads to less readable code than the intended form ``` pointerInput Unit detectTapGestures ```

Javier · Answer

`clickable` allows getting the offset click position

Javier · Answer

About the autocomplete it is not caused by Android Studio I use named params if there are more than one param but I would like `block` to be renamed to something more descriptive

Javier · Answer

I have to try but I am not sure if `detectTapGestures` works if I am pressing a `Button` inside a `Box` and the `detectTapGestures` is applied to the `Box` itself Basically I need to know where the user is clicking to do an animation based on that independently in which children the user clicks

Javier · Answer

I have tried and it looks like I was supposing the click in the child `Button` is not detected by the parent box

Adam Powell · Answer

If you re looking to passively observe input from a parent as children may or may not handle it you likely want the other facilities of `awaitPointerInputScope` in `pointerInput` You ll see all events before children do in the initial pass

Javier · Answer

`awaitPointerInputScope currentEvent changes` should be changing the list after every click It is always empty and the type is `Unknown`

Adam Powell · Answer

you ll want to use the `awaitPointerEvent` function to await the next event Loop as desired

Javier · Answer

Is it safe to do `while true `

Adam Powell · Answer

So long as you re making a cancelable suspend call in that loop so that cancellation can break out of it when the modifier leaves the composition yes

Adam Powell · Answer

e g awaiting the next event

Javier · Answer

I have the `awaitPointerEvent` in the parent composable but I can t still detect if the child `Button` is pressed and where was it pressed I am forced to set that modifier to the `Button` too I tried all possible passes no luck ```Initial Down the tree from ancestor to descendant Main Up the tree from descendant to ancestor Final Down the tree from ancestor to descendant ```
