Hiding the title bar of DockableWindow

[Lukas_cp]

I'm trying to hide the title bar of DockableWindow, but this line has no visible effect.

DockableWindow.ShowTitleBar = false;

This is how I instantiate the DockableWindow.

_buttonDefinition = _inventorApplication.CommandManager.ControlDefinitions.AddButtonDefinition
(
    DisplayName: "My command", 
    InternalName: "MyCommand.InternalName",
    Classification: CommandTypesEnum.kShapeEditCmdType,
    ClientId: _clientId
);

_buttonDefinition.AutoAddToGUI();
_buttonDefinition.OnExecute += ButtonDefinitionOnExecute;

_dockableWindow = _inventorApplication.UserInterfaceManager.DockableWindows.Add
(
    ClientId: _clientId,
    InternalName: "MyDockableWindow.InternalName",
    Title: "My Dockable Window"
);

_dockableWindow.ShowTitleBar = false;

Is there any way to hide or remove the title bar?

Thanks

Lukas

Indeed I see that it has no effect.

This I-logic code shows that it has no effect.

Dim _dockableWindow As Inventor.DockableWindow = ThisApplication.UserInterfaceManager.DockableWindows.Add("1235srs","MyDockableWindow.InternalNamesrs","My Dockable Windowssr")


_dockableWindow.SetDockingState(DockingStateEnum.kFloat)
_dockableWindow.ShowTitleBar = True
MsgBox(_dockableWindow.ShowTitleBar)
_dockableWindow.ShowTitleBar = False
MsgBox (_dockableWindow.ShowTitleBar)

@johnsonshiue Could you and your team take a look at the behavior?
