Dockable pane focus

Anonymous — Wed, 03 Jul 2019 09:14:03 GMT

Hi
I created a dockable pane with some functionality.

I need to automatically change focus on the model viewer when the panel disappears from the cursor field, as it is done in properties panel.

When you do something on properties panel
and then moves the cursor to the model then the focus will also automatically change.
Can you help me, please.

Hi:

Suppose inside the dockable pane, you are using a WPF Page.

Subscribe the Page.MouseLeave

// Add the following lines in you own Page class

public partial class YourPage : Page
    {
        [DllImport("user32.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool SetForegroundWindow(IntPtr hWnd);

        public IntPtr RevitWindowHandle { get; set; }

        void Page_MouseLeave (object sender, MouseEventArgs e)
        {
              SetForegroundWindow (RevitWindowHandle);
        }

About how to get the correct Revit window handle, Please refer the link: revit-window-handle-and-modeless-dialogues.html . Notice that with Revit 2018 or ealier, you can also add reference AdWindows.dll inside the Revit program folder (C:\Program Files\Autodesk\Revit201X\), and use the Autodesk.Windows.ComponentManager.ApplicationWindow to grab Revit window pointer. In Revit 2019, it's much easier, Revit API provides a property: UIApplication.MainWindowHandle.

unfortunately it does not work
debugger coming in the method
and the SetForegroundWindow return true
but the focus is always on the panel
until I myself click on the mouse in the view

I get RevitWindowHandle from the commandData.Application.MainWindowHandle

Hi,

there is a related thread:

https://forums.autodesk.com/t5/revit-api-forum/click-on-dock-pane-deselects-elements/m-p/5279637

As you mention the Properties palette, in the SetupDockablePane method, you may assign EditorInteractionType.KeepAlive.

RevitAPI.chm says:

Keeps the active editor alive during pane activation. This results in the current selection being kept active and available to the pane. One example built-in dockable pane that uses this mode is the Revit Property Palette.

Great!

Thanks for sharing.

I re-tested the "SetForegroundWindow" solution again, and it TRULY did not work.

@AnonymousOOPs for giving you the wrong answer.
