B4J Question moveMouse

magarcan · Dec 11, 2019

Here is my code:

B4X:

Dim robot As JavaObject
robot.InitializeNewInstance("javafx.scene.robot.Robot", Null)
robot.RunMethod("mouseMove", Array As Object(250, 250))

java.lang.RuntimeException: Method: mouseMove not matched.

Any idea why?

PD: using open jdk 11

My best guess is your event declaration is wrong....
You could use this instead... Much simpler.

Take a look at the documentation: https://openjfx.io/javadoc/11/javafx.graphics/javafx/scene/robot/Robot.html

mouseMove requires parameters of type Double, Passing 250, passes an Int variable. Passing 250.0 passes the parameter as a double so this works:

B4X:

Dim robot As JavaObject
    robot.InitializeNewInstance("javafx.scene.robot.Robot", Null)
    robot.RunMethod("mouseMove", Array As Object(250.0, 250.0))

Or you could declare variables as Double first then pass those.

Best way is to create a sub for this:

B4X:

Sub MoveMouse(x as double, y as double)
Dim robot As JavaObject
    robot.InitializeNewInstance("javafx.scene.robot.Robot", Null)
    robot.RunMethod("mouseMove", Array (x, y))
 End Sub
