InputFocusController.NavigateFocusRequested 事件

定義

命名空間:

Microsoft.UI.Input

當 Content.ContentIsland 主機想要 ContentIsland 取得焦點時發生。

例如，使用者已透過主機的元素進行索引標籤，而現在必須分頁至 ContentIsland。 裝載應用程式會在與 SiteBridge 相關聯的 InputFocusNavigationHost 上呼叫 InputFocusNavigationHost.NavigateFocus (Microsoft.UI.Input.FocusNavigationRequest) 。 ContentIsland 的 InputFocusController 接著會收到此 NavigateFocusRequested 事件，並可決定是否要取得焦點。

// Register
event_token NavigateFocusRequested(TypedEventHandler<InputFocusController, FocusNavigationRequestEventArgs const&> const& handler) const;

// Revoke with event_token
void NavigateFocusRequested(event_token const* cookie) const;

// Revoke with event_revoker
InputFocusController::NavigateFocusRequested_revoker NavigateFocusRequested(auto_revoke_t, TypedEventHandler<InputFocusController, FocusNavigationRequestEventArgs const&> const& handler) const;

public event TypedEventHandler<InputFocusController,FocusNavigationRequestEventArgs> NavigateFocusRequested;

function onNavigateFocusRequested(eventArgs) { /* Your code */ }
inputFocusController.addEventListener("navigatefocusrequested", onNavigateFocusRequested);
inputFocusController.removeEventListener("navigatefocusrequested", onNavigateFocusRequested);
- or -
inputFocusController.onnavigatefocusrequested = onNavigateFocusRequested;

Public Custom Event NavigateFocusRequested As TypedEventHandler(Of InputFocusController, FocusNavigationRequestEventArgs) 

事件類型

TypedEventHandler<InputFocusController,FocusNavigationRequestEventArgs>

備註

設定 FocusNavigationRequestEventArgs 的結果值並不會隱含地設定焦點。 TrySetFocus 必須明確呼叫。
