How can I get the state of a toolwindow

Hello,

We don't currently have events that are fired when the auto-hide flyout is opened/closed. I've added this forum post to our TODO item for this feature, so you will be notified when it's completed.

The auto-hide tabs are represented by the AutoHideTabItem type. So you can add a PreviewMouseLeftButtonDown event handler on the DockSite (or another element above it in the visual tree), then look for that type as the e.OriginalSource.

Sorry,I had tried to add a PreviewMouseLeftButtonDown event handler on the DockSite,but I haven't catch a AutoHideTabItem type as the e.OriginalSource.

Please help me to confirm and send the source code to me, thank you！

Sorry, you're right. You would either need to add a class event handler for the AutoHideTabItem type, or in your DockSite handler iterate over the descendents and see if the mouse is over any AutoHideTabItems. You can use our VisualTreeHelperExtended to gather all the AutoHideTabItems, but the class handler is probably the better bet.

OK,thanks.
Now I only want to konw how can I catch an event when I click the AutoHide button？

Hello,

You would probably have to restyle the ToolWindowContainer and replace the DockingCommands.ToggleWindowAutoHideState command with a custom command. The ToolWindowContainer currently handles the DockingCommands.ToggleWindowAutoHideState, so you wouldn't be able intercept it. We don't currently have an event with a ToolWindowContainer/ToolWindow is auto-hidden, but I've added this forum post to the associated TODO item so you will be notified when it's completed.

Hello, we have added new events so that you can be notified of when an auto-hide popup (flyout) is opening or closing.  These events will be part of the future 2014.1 version.  Please see this blog post for details:
