DisplayPropertiesEventHandler 代理人

定義

注意

Windows 8.1之後,可能會變更或無法使用DisplayProperties類型和相關的事件處理常式。 請改用 DisplayInformation

表示處理顯示內容事件的方法。

範例

#include <winrt/Windows.Graphics.Display.h>
using namespace winrt;
using namespace Windows::Graphics::Display;
...
void GameRenderer::Initialize()
{
    DisplayProperties::StereoEnabledChanged({ this, &GameRenderer::OnStereoEnableChanged });
}

void GameRenderer::OnStereoEnableChanged(winrt::Windows::Foundation::IInspectable const& sender)
{
    UpdateForStereoChange();
}
void GameRenderer::Initialize()
{
    DisplayProperties::StereoEnabledChanged += 
        ref new DisplayPropertiesEventHandler(this, &GameRenderer::OnStereoEnableChanged);
}

void GameRenderer::OnStereoEnableChanged(_In_ Platform::Object^ sender)
{
    UpdateForStereoChange();
}

備註

我們建議應用程式使用單一委派來處理大部分的顯示事件,因為在大部分情況下,每個顯示內容的變更都需要應用程式重新繪製本身。 此外,許多屬性變更都來自影響整個作業系統的單一模式變更。
