c++ - 2つのOpenGLグラフィックビューを備えたMFCMDIスプリッターが機能していません

Question

スプリッターを使用してチャイルドフレームに接続された2つの異なるビューでアプリケーションビューがOpenGL3dモデルで分割されるアプリケーションを作成したいと思います。この目的のために、私はビュークラスから拡張された親クラスを作成し、このクラス内ですべてのopenglに必要なコードを初期化しました。

例えば

#pragma once

#include <gl/gl.h>
#include <gl/glu.h>

#define IL   //when you dont want to use image library and you want to load everything by your self then remove this

次に、同じクラスクラスからさらに2つのビュークラスを拡張しました

C3dRightView : public COpenGlView

と

C3dRightView : public COpenGlView

次に、子フレームクラスでスプリッターコードを追加し、スプリッターウィンドウでこれら2つのクラスを呼び出しました。問題は、両方のopenglビューコードが正常に機能することですが、openglの初期化の1つを停止すると、もう1つが表示されます。私はすべてを試しましたが、これら2つの異なるビューの両方で2つの異なるグラフィカルopenglアニメーションを表示できません。HDCメモリマップを確認しましたが、両方のクラスが動的hdcオブジェクトに関して親を使用しているようですが、コードを停止すると、他のビューが正しく表示されます。

ビューのinitialupdate関数内のコードの下にコメントがある場合、他のビューコードは正常に機能します。

    COpenGlView::OnInitialUpdate();
    oglInitialize();

親コードのinitialupdateコードが、2つではなく、1つの子に対してどのように機能するか。

編集：wglMakeCurrent()理由は私が最初に思ったようにすることはできません、あなたはそれを十分に呼んでいるようです。

oglInitialize()ただし、電話をかける回数が多すぎることが理由かもしれません。ビューとスプリッターをどのように作成するかによって異なりますが、投稿しなかったコードです。これを修正する1つの方法は、ビューが実際に「最初に更新」される回数を制限することです。

コンストラクターでメンバーを0に初期化しますhdc（実際には、コンストラクターで常にすべてのメンバーを初期化します）。

COpenGlView::COpenGlView()
{
    hdc = 0;
    // ... etc your stuff
}

hdcが0の場合、oglの初期化を1回だけ実行します。

void C3dRightView::OnInitialUpdate()
{
    if ( hdc == 0 )
    {
        hdc = GetDC()->m_hDC;
        COpenGlView::OnInitialUpdate();
        oglBeginRendering();
    }
}

こちらも：

void C3dLeftView::OnInitialUpdate()
{
    if ( hdc == 0 )
    {
        hdc = GetDC()->m_hDC;
        COpenGlView::OnInitialUpdate();
        oglBeginRendering();
    }
}

それは私が信頼するように機能するはずです。

Edit2：コードを試しました。C3dRightView::OnInitialUpdate私が上に投稿したようなものではありませんでした。何が初期化を台無しにするのか正確にはわかりません。たとえば、次の修正は機能して CChildFrame::OnCreateClientいるようです。

if (!m_wndSplitter.CreateView( 0, 1, RUNTIME_CLASS(C3dRightView), CSize(cr.Width()/2, cr.Height()), pContext))
{
    MessageBox(L"Error setting up splitter frames!", L"Init Error!", MB_OK | MB_ICONERROR);
    return FALSE;
}

// had to add this line here:
m_wndSplitter.GetPane( 0, 1 )->SendMessage(WM_INITIALUPDATE);

return TRUE;

遅いかもしれませんが、これが将来あなたを助けることができる私の答えです:)

Ontimer関数呼び出しpdoc->UpdateAll(NULL,NULL,NULL)関数で。pdocは、ドキュメントクラスへのポインタです。すべてのビューの更新を要求し、両方のウィンドウが機能するようになります:)。
