* Fixes #2776. Pressing Alt key on a Window with only a MenuBar throws System.InvalidOperationException. * Add unit test. * Fix extra bracket. * Prevents throw exception if Application.Current is null. * Fix unit test because OnLeave is now invoked on toplevel removing, preventing two views having focus. * Fix unit test method name. * Fix Window by not layout on his subviews when adding a new view after the Application.Begin was already running. * FindAndOpenMenuByHotkey now search inside Menus and inside his Children. * Add unit test for Window LayoutSubviews and FindAndOpenChildrenMenuByHotkey menu method. * Prevents button to be clear when it's invisible. * Fixes 2780. Moving a Window that is Application.Top shouldn't be allowed. * Fix condition if Window and Application.Top. * Always LayoutSubviews and PositionToplevels after Clear. * Fixes #2787. MenuItem with CanExecute returning false is select when a MenuBar is opened. * Leveraging the power of CanExecute feature. * Fixes #2789. StatusItem should have a disabled attribute if it can't execute. * Allows positioning a child window outside the limits of the menu and the status bar. * Change to a more appropriate name. * Simplifies all the run actions. * Prevents open menu bar if it's invisible and close all opened menus. * Fix mdi run loop. * Fix hot key on mdi toplevels. * Fix position on mdi toplevels. * Fix Top.Redraw by set state.Toplevel.SetNeedsDisplay if it's needed to redraw. * Fix MdiTop by repainted when a keystroke is generated by keyboard. * Rename local fields. * Force redraw if application.Top needs display. * Added more features to the scenario. * Change the scenarios to run as Application.Top instead of sub-views. * Add a new scenario similar but as Mdi Container. * Add a bunch of new unit tests to prove all this PR. * Only it's need to redraw Application.Top if it's a Mdi Container. * Remove unnecessary code. * Unit test that proves that a MDI child leaves no trace when the location is changed. * Removes unnecessary Application.Init because theses uses Run<T> which already call it. * Ensures a menu bar been closed after run an action. * Ensures that another view can be focused if not IsMenuOpen and LastFocused is null, instead of focused the menu itself. * Ensures a focused contentview subview being focused if MostFocused is null. * Ensures a MdiTop subview to have priority if it's focused and thus make it Current. * Allow a MdiChild be closed when pressing Application.QuitKey. * More unit tests proving the changes. * Ensures the top.MostFocused is focused. * Ensures MdiChild on the front if MdiTop.MostFocused isn't valid, like ContentView. * Add unit test showing MdiChild on the front. * Fix an issue where NullReferenceException can be throws everywhere while get the Application.MdiChildes property. --------- Co-authored-by: Tig <tig@users.noreply.github.com>
