B4J Question Get Current Mouse Pointer Type (inline JAVA)

[Magma]

Hi there...

how can i use "java.awt.Cursor.getType()" to get current mouse pointer type (for example hourglass, resize) from any app-window in foreground ?

Anyone used it ... ?

Thanks in advance !

B4J UI is implemented with JavaFX not AWT so you can't. You could try the code below. If you don't explicitly set the cursor to a JavaFX one it appears to return Null. I'm not very well acquainted with JavaFX but it seems to work.

Sub Button1_Click
    Dim formm, scene, cursor As JavaObject
    formm = MainForm
    scene = formm.GetField("scene")   
    Log(scene.RunMethod("getCursor", Null))
    cursor.InitializeStatic("javafx.scene.Cursor")
    scene.RunMethod("setCursor", Array(cursor.GetField("CLOSED_HAND")))
    Log(scene.RunMethod("getCursor", Null))
End Sub

If it is not a b4j window active... if it is desktop of windows... or different app ?

how can we get it ?

I don't think you can. In JavaFX/B4J the cursor belongs to a form.

From a different app - get active window - mouse cursor ? ??

Why do you need to? You would need to poke around inside Windows itself to do such things.

Well I need it for an app: remote administration... .when capturing screen not getting mousepointer... so need to know type of mousepointer i have in remote... to set it at my client window...

thought that in #IFJAVA... java.awt.Cursor.getType() will do the job... because already used other java.awt.* and worked...

....hmmm...

@agraham Super "thanks" for your time !

hmmm.. What about....

• com.sun.jna.platform.win32.WinDef.HICON
  
  • com.sun.jna.platform.win32.WinDef.HCURSOR

I'm a bit rusty on the Windows API and have never used JNA Win32 but in Windows each input thread has a cursor and each window has an input thread to handle the message loop so each window has its own cursor - the desktop itself is a window. To get the cursor you would need to get the window handle of the window of interest and take it from there but I can't tell you how to do that with JNA.

@agraham I understand...

I am posting here not only to answered by you (Thanks again) - hope, others see and if already know help me....

Found some code after a lot of searching - that may be help to extract the GetCursor needed (i just wanna know the type... of mousecursor of any windows is front or desktop) - So may be need to use HWND, may be others... my java knowledge is too little for that...
