B4J Question Trying to get coordinates of mouse click out of the application

[Chicao99]

Is there an updated way to do that?

Looks like it is possible to get the mouse coordinates with: https://stackoverflow.com/a/6050894/971547

I don't think that it is possible to get click events.

Try this code and if it doesn't work, blame ChatGPT who just generated it, don't blame me ?

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.Show
    
    ' Inizializza il listener globale del mouse
    InitializeGlobalMouseListener(Me, "MouseClicked")
End Sub

' Questa Sub sarà chiamata quando un click del mouse globale viene intercettato
Sub MouseClicked(x As Double, y As Double)
    Log($"Mouse clicked at X=${x}, Y=${y}"$)
    ' Qui puoi aggiungere il codice per eseguire azioni specifiche
End Sub

#If JAVA
    import java.awt.Toolkit;
    import java.awt.event.AWTEventListener;
    import java.awt.event.MouseEvent;
    import anywheresoftware.b4j.objects.MouseClickListener;

    public static void InitializeGlobalMouseListener(Object b4jClassInstance, String b4jMethodName) {
        Toolkit.getDefaultToolkit().addAWTEventListener(
            new AWTEventListener() {
                @Override
                public void eventDispatched(AWTEvent event) {
                    if (event instanceof MouseEvent) {
                        MouseEvent mouseEvent = (MouseEvent) event;
                        double x = mouseEvent.getX();
                        double y = mouseEvent.getY();
                        try {
                            anywheresoftware.b4j.objects.MouseClickListener.class.getMethod(b4jMethodName, double.class, double.class)
                                .invoke(b4jClassInstance, x, y);
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                    }
                }
            },
            AWTEvent.MOUSE_EVENT_MASK
        );
    }
#End If

I already see that the part explained in this thread is missing:
