語法

void FillRoundedRectangle(
       const D2D1_ROUNDED_RECT *roundedRect,
  [in] ID2D1Brush              *brush
);

參數

roundedRect

類型：[in] const D2D1_ROUNDED_RECT*

傳回值

無

備註

如果此方法失敗，此方法不會傳回錯誤碼。 若要判斷繪圖作業是否 (FillRoundedRectangle) 失敗，請檢查 ID2D1RenderTarget：：EndDraw 或 ID2D1RenderTarget：：Flush 方法傳回的結果。

範例

下列範例會使用 DrawRoundedRectangle 和 FillRoundedRectangle 方法來大綱和填滿圓角矩形。 此範例會產生下圖所示的輸出。

//  Called whenever the application needs to display the client
//  window.
HRESULT DrawAndFillRoundedRectangleExample::OnRender()
{
    HRESULT hr;

    // Create the render target and brushes if they
    // don't already exists.
    hr = CreateDeviceResources();

    if (SUCCEEDED(hr))
    {
        // Retrieve the size of the render target.
        D2D1_SIZE_F renderTargetSize = m_pRenderTarget->GetSize();

        m_pRenderTarget->BeginDraw();
        m_pRenderTarget->SetTransform(D2D1::Matrix3x2F::Identity());
        m_pRenderTarget->Clear(D2D1::ColorF(D2D1::ColorF::White));

        // Paint a grid background.
        m_pRenderTarget->FillRectangle(
            D2D1::RectF(0.0f, 0.0f, renderTargetSize.width, renderTargetSize.height),
            m_pGridPatternBitmapBrush
            );

        // Define a rounded rectangle.
        D2D1_ROUNDED_RECT roundedRect = D2D1::RoundedRect(
            D2D1::RectF(20.f, 20.f, 150.f, 100.f),
            10.f,
            10.f
            );

        // Draw the rectangle.
        m_pRenderTarget->DrawRoundedRectangle(roundedRect, m_pBlackBrush, 10.f);

        // Apply a translation transform.
        m_pRenderTarget->SetTransform(D2D1::Matrix3x2F::Translation(200.f, 0.f));

        // Draw the rounded rectangle again, this time with a dashed stroke.
        m_pRenderTarget->DrawRoundedRectangle(roundedRect, m_pBlackBrush, 10.f, m_pStrokeStyle);

        // Apply another translation transform.
        m_pRenderTarget->SetTransform(D2D1::Matrix3x2F::Translation(0.f, 150.f));

        // Draw, then fill the rounded rectangle.
        m_pRenderTarget->DrawRoundedRectangle(roundedRect, m_pBlackBrush, 10.f, m_pStrokeStyle);
        m_pRenderTarget->FillRoundedRectangle(roundedRect, m_pSilverBrush);

        // Apply another translation transform.
        m_pRenderTarget->SetTransform(D2D1::Matrix3x2F::Translation(200.f, 150.f));

        // Fill, then draw the rounded rectangle.
        m_pRenderTarget->FillRoundedRectangle(roundedRect, m_pSilverBrush);
        m_pRenderTarget->DrawRoundedRectangle(roundedRect, m_pBlackBrush, 10.f, m_pStrokeStyle);

        hr = m_pRenderTarget->EndDraw();

        if (hr == D2DERR_RECREATE_TARGET)
        {
            hr = S_OK;
            DiscardDeviceResources();
        }
    }

    return hr;
}
