How to obtain the coordinates of mouse clicks on stage in JSFL？

[Meason Louis]

I have rewritten these two methods in the jsx file without any effect

function mouseDown() {
    fl.trace("Mouse button has been pressed");
}
function mouseDown(pt) {
    fl.trace("x = "+ pt.x+" :: y = "+pt.y);
}

This method may also report errors

 fl.addEventListener("mouseDown", myFunction);

Thank you very much if you can!

no such event for fl.  check the api.

[Meason Louis]

Thank you for your answer，this method is used in the API, but I don't know how to use it

function mouseDown() {
    fl.trace("Mouse button has been pressed");
}
function mouseDown(pt) {
    fl.trace("x = "+ pt.x+" :: y = "+pt.y);
}

fl has that method, but not that event.  further there is no jsfl object that has that method and event.  ie, use an on-stage object.

[Meason Louis]

Thank you, got it.  another problem, this event is ok, with log output

function onMove() {
  fl.removeEventListener("mouseMove", myFunction)
}

function myFunction() {
  fl.trace("move");
}

But this is not output log 

function myFunction(pt) {
  fl.trace("x = " + pt.x + " :: y = " + pt.y);
}

I see that the API has this method, may I ask how to write it, Thank you again

myFunctions argument is the event, not a point, assuming you're using a mousemove event listener 

[Meason Louis]

Sorry, I made a mistake in copying, It should be this code

fl.addEventListener("mouseMove", myFunction);

I changed it to event

function myFunction(event) {
  fl.trace(event);
}

but log print  undefined

this code worked for me

Hi.

These methods are for extensible tools: activate(), configureTool(), deactivate(), keyDown(), keyUp(), mouseDoubleClick(), mouseDown(), mouseMove(), mouseUp(), notifySettingsChanged(), and setCursor().

The PolyStar tool uses the structure/code of an extensible tool. You can find it in:

got it, this means that I cannot add these events in my customized panel, but need to use the add extension tool to achieve

[JoãoCésar]

Using an extensible tool is probably the best way to track the cursor position. Listening to the "mouseMove" event is also possible, although I think it's kinda tricky to use it.

But what exactly do you need to do?

[Meason Louis]

I want to quickly draw a circle between two points, so I need two coordinates to calculate, such as quickly drawing a green circle that can be tangent to two points

If you want to implement shape creation with JSFL, I recommend examining the script PolyStar.jsfl located in the Tools subfolder. It demonstrates the correct usage of mouseDown(), mouseUp(), and mouseMove().

I advise against subscribing to the mouseMove event. While technically possible, I believe it is not a good practice. I have seen panels that degrade the overall program performance because they subscribed to computationally intensive functions on mouseMove.

If you want to incorporate drawing as a functionality in your panel, write it as a tool script, and then integrate it appropriately in the panel using:

MMExecute( "fl.selectTool( 'yourCustomToolName' );" );

Thank you very much, I will follow this idea
