From f3862ecf86530a9341002fcab287ae1dcfccaf53 Mon Sep 17 00:00:00 2001 From: Dilip Ojha Date: Tue, 14 Jan 2020 05:23:04 +1100 Subject: [PATCH] Move NavigationView to Repeater (#1683) * replaced listview with repeater * removed NavigationViewList from DisableAnimationsStyles * fixed release build error * addressed some comments * addressed some more comments * items repeater update * addressed more comments * removed state machine * addressed more comments * fixed settings * fixed SelectionChanged raised due to initialization order * fixed merge * added datacontext use case page and test * addressed comments * addressed more comments * re-added downlevel testpages * updated focus navigation behavior - update focus behavior - fix repeater bug * fixed pane content width bug * updated/fixed tests * updated masters * fixed/updated tests * addressed comments * reverted downlevel flag behavior reverted ShouldPreserveNavigationViewRS4Behavior and ShouldPreserveNavigationViewRS3Behavior to old behavior. Old behavior was inccorectly determining OS version, however updating to correct behavior breaks tests, so reverting to old behavior for now * added repeater API test, fixed pre-rs5 header visibility test * updated masters * moved preview API call, reset masters * address comment * updated visual verification test --- ...avigationViewAutomationPeer.properties.cpp | 16 + dev/Generated/StackLayout.properties.cpp | 31 + dev/Generated/StackLayout.properties.h | 9 + dev/NavigationView/NavigationView.cpp | 1835 +++++---- dev/NavigationView/NavigationView.h | 183 +- dev/NavigationView/NavigationView.idl | 9 - dev/NavigationView/NavigationView.vcxitems | 7 +- dev/NavigationView/NavigationView.xaml | 107 +- .../NavigationViewAutomationPeer.cpp | 52 + .../NavigationViewAutomationPeer.h | 27 + dev/NavigationView/NavigationViewHelper.h | 4 +- dev/NavigationView/NavigationViewItem.cpp | 34 +- dev/NavigationView/NavigationViewItem.h | 10 +- .../NavigationViewItemAutomationPeer.cpp | 100 +- .../NavigationViewItemAutomationPeer.h | 12 +- .../NavigationViewItemAutomationPeer.idl | 13 +- dev/NavigationView/NavigationViewItemBase.cpp | 27 +- dev/NavigationView/NavigationViewItemBase.h | 14 +- .../NavigationViewItemRevokers.h | 14 + .../NavigationViewItemSeparator.cpp | 4 +- .../NavigationViewItemSeparator.h | 2 +- .../NavigationViewItemsFactory.cpp | 69 + .../NavigationViewItemsFactory.h | 23 + dev/NavigationView/NavigationViewList.cpp | 140 - dev/NavigationView/NavigationViewList.h | 45 - .../NavigationViewTests.cs | 2 +- .../NavigationViewTests.cs | 68 +- .../TestUI/NavigationViewCaseBundle.xaml | 1 + .../TestUI/NavigationViewCaseBundle.xaml.cs | 1 + .../NavigationViewItemTemplatePage.xaml | 1 - .../TestUI/NavigationViewPageDataContext.xaml | 33 + .../NavigationViewPageDataContext.xaml.cs | 49 + .../TestUI/NavigationViewRS3Page.xaml | 468 --- .../TestUI/NavigationViewRS4Page.xaml | 369 -- .../TestUI/NavigationView_TestUI.projitems | 35 +- .../TopNavigationViewDataProvider.cpp | 31 +- .../TopNavigationViewDataProvider.h | 3 +- dev/Repeater/APITests/LayoutTests.cs | 30 + dev/Repeater/FlowLayout.cpp | 1 + dev/Repeater/FlowLayoutAlgorithm.cpp | 10 +- dev/Repeater/FlowLayoutAlgorithm.h | 2 + dev/Repeater/ItemsRepeater.cpp | 25 +- dev/Repeater/ItemsRepeater.idl | 6 + dev/Repeater/StackLayout.cpp | 1 + dev/Repeater/TestUI/Samples/BasicDemo.xaml | 6 +- dev/Repeater/TestUI/Samples/BasicDemo.xaml.cs | 7 +- dev/Repeater/UniformGridLayout.cpp | 1 + .../Themes/DisableAnimationsStyles.xaml | 4 +- .../master/NavigationViewAuto-7.xml | 1108 ++---- .../master/NavigationViewAuto-8.xml | 1108 ++---- .../master/NavigationViewAuto.xml | 1101 ++---- .../master/NavigationViewLeftCompact-7.xml | 747 ++-- .../master/NavigationViewLeftCompact-8.xml | 747 ++-- .../master/NavigationViewLeftCompact.xml | 750 ++-- .../master/NavigationViewLeftMinimal-7.xml | 726 ++-- .../master/NavigationViewLeftMinimal-8.xml | 726 ++-- .../master/NavigationViewLeftMinimal.xml | 729 ++-- .../NavigationViewLeftPaneContent-7.xml | 726 ++-- .../NavigationViewLeftPaneContent-8.xml | 726 ++-- .../master/NavigationViewLeftPaneContent.xml | 707 ++-- .../master/NavigationViewScrolling-7.xml | 3292 ++++------------ .../master/NavigationViewScrolling-8.xml | 3294 ++++------------- .../master/NavigationViewScrolling.xml | 3250 ++++------------ .../master/NavigationViewTop-7.xml | 726 ++-- .../master/NavigationViewTop-8.xml | 726 ++-- .../master/NavigationViewTop.xml | 729 ++-- .../master/NavigationViewTopPaneContent-7.xml | 726 ++-- .../master/NavigationViewTopPaneContent-8.xml | 726 ++-- .../master/NavigationViewTopPaneContent.xml | 707 ++-- 69 files changed, 10242 insertions(+), 17776 deletions(-) create mode 100644 dev/Generated/NavigationViewAutomationPeer.properties.cpp create mode 100644 dev/NavigationView/NavigationViewAutomationPeer.cpp create mode 100644 dev/NavigationView/NavigationViewAutomationPeer.h create mode 100644 dev/NavigationView/NavigationViewItemRevokers.h create mode 100644 dev/NavigationView/NavigationViewItemsFactory.cpp create mode 100644 dev/NavigationView/NavigationViewItemsFactory.h delete mode 100644 dev/NavigationView/NavigationViewList.cpp delete mode 100644 dev/NavigationView/NavigationViewList.h create mode 100644 dev/NavigationView/TestUI/NavigationViewPageDataContext.xaml create mode 100644 dev/NavigationView/TestUI/NavigationViewPageDataContext.xaml.cs diff --git a/dev/Generated/NavigationViewAutomationPeer.properties.cpp b/dev/Generated/NavigationViewAutomationPeer.properties.cpp new file mode 100644 index 0000000000..215f141ea9 --- /dev/null +++ b/dev/Generated/NavigationViewAutomationPeer.properties.cpp @@ -0,0 +1,16 @@ +// Copyright (c) Microsoft Corporation.
