B4J Question CTRL+V with message - Method: keyPress not matched

petr4ppc · May 28, 2019

Dear friends,

please for advice, I am using ctrl + v for paste:

B4X:

    Dim ta As TextArea
    ta.Initialize("ta")
    Dim jo As JavaObject = ta
    jo.RunMethod("paste", Null)
    ta.SelectAll

robot.RunMethod("keyPress", Array As Object(17))  
robot.RunMethod("keyPress", Array As Object(86))
robot.RunMethod("keyRelease", Array As Object(17))
robot.RunMethod("keyRelease", Array As Object(86))

and I got this message:

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

Please, what can I do with this? It was functioned in older version of Java

Erel · May 29, 2019

What is the purpose of this code? You should remove it.

B4X:

If fx.Clipboard.HasString Then
       ta.Text = fx.Clipboard.GetString
 End If

petr4ppc · May 29, 2019

Thank you very much for answer,

the purpose is, that I want place the string programaticaly with function CTRL+V to cursor position (for example if I have opened notepad)
I have string in clipboard - this is OK,
but I am doing some mistake with:

B4X:

robot.RunMethod("keyPress", Array As Object(17)) 
robot.RunMethod("keyPress", Array As Object(86))
robot.RunMethod("keyRelease", Array As Object(17))
robot.RunMethod("keyRelease", Array As Object(86))

I get:

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

No need to write Array As Object. It is enough to write Array.

How is robot initialized?

petr4ppc · May 29, 2019

Thank you for your answer Erel,

Robot init:

B4X:

    robot = temp.InitializeStatic("com.sun.glass.ui.Application").RunMethodJO("GetApplication",Null).RunMethodJO("createRobot",Null)

I am using this:

B4X:

#VirtualMachineArgs: --add-opens javafx.graphics/com.sun.glass.ui=ALL-UNNAMED

Now I am using this code (without "object"):

B4X:

    robot.RunMethod("keyPress", Array (17))
    robot.RunMethod("keyPress", Array (86))
    robot.RunMethod("keyRelease", Array (17))
    robot.RunMethod("keyRelease", Array (86))

and I still get:

Have you tried it with the new robot class in java 11 javafx.scene.robot?

api doc here : https://openjfx.io/javadoc/11/javafx.graphics/javafx/scene/robot/Robot.html

Erel · May 30, 2019

Example:

B4X:

Dim robot As JavaObject
robot.InitializeNewInstance("javafx.scene.robot.Robot", Null)
Dim KeyCode As JavaObject
KeyCode.InitializeStatic("javafx.scene.input.KeyCode")
robot.RunMethod("keyPress", Array(KeyCode.GetField("A")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("A")))

Keycodes: https://openjfx.io/javadoc/11/javafx.graphics/javafx/scene/input/KeyCode.html

petr4ppc · May 30, 2019

Thank you very much dear B4X friends,

Erel - it is 100% perfect, thank you very much and best regards

Hi to all
Why this not work?

B4X:

robot.RunMethod("keyPress", Array(KeyCode.GetField("LEFT_PARENTHESIS")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("LEFT_PARENTHESIS"))
....
and more

instead of constants how can I directly use the value of the key pressed?
Thanks

Edit:
Sorry, I forgot to use the shift key
but the question always remains valid

Keyboard Italian Layout
how do i insert @?

B4X:

robot.RunMethod("keyPress", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("AT"))
'Not work
....
robot.RunMethod("keyPress", Array(KeyCode.GetField("ALT")))
robot.RunMethod("keyPress", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("ALT")))
'Not work
??

Thanks

agraham · Oct 24, 2020

Try

B4X:

robot.RunMethod("keyPress", Array(KeyCode.GetField("ALT_GRAPH")))
robot.RunMethod("keyPress", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("AT")))
robot.RunMethod("keyRelease", Array(KeyCode.GetField("ALT_GRAPH")))

I'm pretty sure the modifier is ALT_GRAPH, it is on an English keyboard key with three characters, but the key might not be AT.
