BridJ - ITaskbarList3 StructObjects

[Joao Rasteiro]

Hi,

I'm trying to add Taskbar Buttons to my application.
I've just recently found BridJ because of this, since it seems to support ITaskBarList3 out of the box which is perfect.

I (think I) have successfully managed to register the required classes and it shows so in the logs:

INFO: Registering type org.bridj.cpp.com.shell.ITaskbarList3
INFO: Registering type org.bridj.cpp.com.shell.ITaskbarList3$THUMBBUTTON

Among other similar prints.

However, whenever I try to set any of THUMBBUTTON's fields I get an UnsatisfiedLinkError.
It seems that either I'm not properly creating the Struct and "attaching" it to its native counterpart or I'm simply doing something wrong.
I was unable to find a tutorial using StructObjects and the ITaskbarDemo only uses progress bar updates which don't use any of these Structs.

Here's part of the code in question:

public void init(JFrame window) {
    ITaskbarList3 buttonList = COMRuntime.newInstance(ITaskbarList3.class);
    Pointer<THUMBBUTTON> buttons = Pointer.allocateArray(THUMBBUTTON.class, 1); //Eventually I'll add more than 1 button
    long handler = JAWTUtils.getNativePeerHandle(window);
    Pointer<?> hwnd = Pointer.pointerToAddress(handler);

    THUMBBUTTON btn = buttons.get(0);
    btn.iId(0); //From here on, any call will throw UnsatisfiedLinkError
    btn.dwMask(THUMBBUTTONMASK.THB_BITMAP);    
    btn.iBitmap(0);
    btn.dwFlags(THUMBBUTTONFLAGS.THBF_ENABLED);
       
    buttonList.ThumbBarAddButtons((Pointer) hwnd, 1, buttons);
}

Any help on how to init/set these Structs properly would be great!

Thanks in advance!
