Prevent auto show on hover, change pin image

Hello, Jure,

I will go straight to your questions:

1. RadDock manages the auto hide popup's showing by using an internal timer. Hence, there is no public API for disabling this functionality. However, RadDock offers the AutoHideWindowDisplaying event which allows you to cancel showing the auto hide popup. However, this will also prevent the popup when you click the tab. The AutoHideWindowDisplayingEventArgs gives you useful information about the action that triggers the auto hide popup:

        private void radDock1_AutoHideWindowDisplaying(object sender, Telerik.WinControls.UI.Docking.AutoHideWindowDisplayingEventArgs e)
        {
            if (e.DisplayReason == Telerik.WinControls.UI.Docking.AutoHideDisplayReason.TabItemHovered)
            {
                e.Cancel = true;
            }
        }

2. It is possible to disable the Floating state after double clicking by cancelling the DockStateChanging event: 

        private void radDock1_DockStateChanging(object sender, Telerik.WinControls.UI.Docking.DockStateChangingEventArgs e)
        {
            if (e.NewDockState == Telerik.WinControls.UI.Docking.DockState.Floating)
            {
                e.Cancel = true;
            }
        }

3. I have prepared a sample code snippet demonstrating how to change the pin icon for a ToolWindow for its Docked state:

          ToolTabStrip strip = this.toolWindow2.DockTabStrip as ToolTabStrip;
          strip.AutoHideButton.Image = Properties.Resources.pin;
          strip.AutoHideButton.DisplayStyle = DisplayStyle.Image;

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
