DXUT 控件图片

DXUT 示例中是用DXUTRes.cpp 中的 g_DXUTGUITextureSrcData存储控件图片内存数据, 然后导入程序使用.

该g_DXUTGUITextureSrcData中的数据是从dxutcontrols.dds转换过来的. dxutcontrols.dds可以到directx 安装目录里搜到.

使用自己的控件图片 

其中添加了圆和箭头按钮

第一步

在DXUTgui.h中 CDXUTDialogResourceManager类中添加函数声明

int AddControlsTexture( LPCWSTR strFilename );

 

第二步

在DXUTgui.cpp中添加函数实现

int CDXUTDialogResourceManager::AddControlsTexture( LPCWSTR strFilename )
{
    DXUTTextureNode* pNewTextureNode = new DXUTTextureNode;
    if( pNewTextureNode == NULL )
        return -1;

    ZeroMemory( pNewTextureNode, sizeof( DXUTTextureNode ) );
    pNewTextureNode->bFileSource = true;
    wcscpy_s( pNewTextureNode->strFilename, MAX_PATH, strFilename );
    
    m_TextureCache.GetAt(0) = pNewTextureNode;

    if( m_pd3d9Device )
        CreateTexture9( 0 );

    return 0;
}

第三步

添加自己的控件函数(以箭头按钮举例)

在DXUTgui.h中CDXUTDialog类的声明中添加

HRESULT             AddArrowButton( int ID, LPCWSTR strText, int x, int y, int width, int height, UINT nHotkey=0 /*热键*/ ,//按钮
         bool bIsDefault=false/* 默认焦点*/, CDXUTArrowButton** ppCreated=NULL );

 

在DXUTgui.cpp中添加实现

HRESULT CDXUTDialog::AddArrowButton( int ID, LPCWSTR strText, int x, int y, int width, int height, UINT nHotkey,
          bool bIsDefault, CDXUTArrowButton** ppCreated )
{
 HRESULT hr = S_OK;

 CDXUTArrowButton* pButton = new CDXUTArrowButton( this );

 if( ppCreated != NULL )
  *ppCreated = pButton;

 if( pButton == NULL )
  return E_OUTOFMEMORY;

 hr = AddControl( pButton );
 if( FAILED( hr ) )
  return hr;

 // Set the ID and list index
 pButton->SetID( ID );
 pButton->SetText( strText );
 pButton->SetLocation( x, y );
 pButton->SetSize( width, height );
 pButton->SetHotkey( nHotkey );
 pButton->m_bIsDefault = bIsDefault;

 return S_OK;
}

 

在DXUTgui.h中添加

class CDXUTArrowButton : public CDXUTStatic
{
public:
 CDXUTArrowButton( CDXUTDialog* pDialog = NULL );

 virtual bool    HandleKeyboard( UINT uMsg, WPARAM wParam, LPARAM lParam );
 virtual bool    HandleMouse( UINT uMsg, POINT pt, WPARAM wParam, LPARAM lParam );
 virtual void    OnHotkey()
 {
  if( m_pDialog->IsKeyboardInputEnabled() ) m_pDialog->RequestFocus( this );
  m_pDialog->SendEvent( EVENT_BUTTON_CLICKED, true, this );
 }

 virtual BOOL    ContainsPoint( POINT pt )
 {
  return PtInRect( &m_rcBoundingBox, pt );
 }
 virtual bool    CanHaveFocus()
 {
  return ( m_bVisible && m_bEnabled );
 }

 virtual void    Render( float fElapsedTime );

protected:
 bool m_bPressed;
};

 

在DXUTgui.cpp中添加实现

CDXUTArrowButton::CDXUTArrowButton( CDXUTDialog* pDialog )
{
 m_Type = DXUT_CONTROL_ARROWBUTTON;
 m_pDialog = pDialog;

 m_bPressed = false;
 m_nHotkey = 0;
}

 

bool CDXUTArrowButton::HandleKeyboard( UINT uMsg, WPARAM wParam, LPARAM lParam )
{
 if( !m_bEnabled || !m_bVisible )
  return false;

 switch( uMsg )
 {
 case WM_KEYDOWN:
  {
   switch( wParam )
   {
   case VK_SPACE:
    m_bPressed = true;
    return true;
   }
  }

 case WM_KEYUP:
  {
   switch( wParam )
   {
   case VK_SPACE:
    if( m_bPressed == true )
    {
     m_bPressed = false;
     m_pDialog->SendEvent( EVENT_BUTTON_CLICKED, true, this );
    }
    return true;
   }
  }
 }
 return false;
}

bool CDXUTArrowButton::HandleMouse( UINT uMsg, POINT pt, WPARAM wParam, LPARAM lParam )
{
 if( !m_bEnabled || !m_bVisible )
  return false;

 switch( uMsg )
 {
 case WM_LBUTTONDOWN:
 case WM_LBUTTONDBLCLK:
  {
   if( ContainsPoint( pt ) )
   {
    // Pressed while inside the control
    m_bPressed = true;
    SetCapture( DXUTGetHWND() );

    if( !m_bHasFocus )
     m_pDialog->RequestFocus( this );

    return true;
   }

   break;
  }

 case WM_LBUTTONUP:
  {
   if( m_bPressed )
   {
    m_bPressed = false;
    ReleaseCapture();

    if( !m_pDialog->m_bKeyboardInput )
     m_pDialog->ClearFocus();

    // Button click
    if( ContainsPoint( pt ) )
     m_pDialog->SendEvent( EVENT_BUTTON_CLICKED, true, this );

    return true;
   }

   break;
  }
 };

 return false;
}

void CDXUTArrowButton::Render( float fElapsedTime )
{
 int nOffsetX = 0;
 int nOffsetY = 0;

 DXUT_CONTROL_STATE iState = DXUT_STATE_NORMAL;

 if( m_bVisible == false )
 {
  iState = DXUT_STATE_HIDDEN;
 }
 else if( m_bEnabled == false )
 {
  iState = DXUT_STATE_DISABLED;
 }
 else if( m_bPressed )
 {
  iState = DXUT_STATE_PRESSED;

  nOffsetX = 1;
  nOffsetY = 2;
 }
 else if( m_bMouseOver )
 {
  iState = DXUT_STATE_MOUSEOVER;

  nOffsetX = -1;
  nOffsetY = -2;
 }
 else if( m_bHasFocus )
 {
  iState = DXUT_STATE_FOCUS;
 }

 // Background fill layer
 //TODO: remove magic numbers
 CDXUTElement* pElement = m_Elements.GetAt( 0 );

 float fBlendRate = ( iState == DXUT_STATE_PRESSED ) ? 0.0f : 0.8f;

 RECT rcWindow = m_rcBoundingBox;
 OffsetRect( &rcWindow, nOffsetX, nOffsetY );

 // Blend current color
 pElement->TextureColor.Blend( iState, fElapsedTime, fBlendRate );
 pElement->FontColor.Blend( iState, fElapsedTime, fBlendRate );

 m_pDialog->DrawSprite( pElement, &rcWindow, DXUT_FAR_BUTTON_DEPTH );
 m_pDialog->DrawText( m_strText, pElement, &rcWindow );

 // Main button
 pElement = m_Elements.GetAt( 1 );

 // Blend current color
 pElement->TextureColor.Blend( iState, fElapsedTime, fBlendRate );
 pElement->FontColor.Blend( iState, fElapsedTime, fBlendRate );

 m_pDialog->DrawSprite( pElement, &rcWindow, DXUT_NEAR_BUTTON_DEPTH );
 m_pDialog->DrawText( m_strText, pElement, &rcWindow );

}

 

在CDXUTDialog::InitDefaultElements()中添加

//箭头
 SetRect( &rcTexture, 270, 20, 380, 54 );
 Element.SetTexture( 0, &rcTexture );
 Element.SetFont( 0 );
 Element.TextureColor.States[ DXUT_STATE_NORMAL ] = D3DCOLOR_ARGB( 150, 255, 255, 255 );
 Element.TextureColor.States[ DXUT_STATE_PRESSED ] = D3DCOLOR_ARGB( 200, 255, 255, 255 );
 Element.FontColor.States[ DXUT_STATE_MOUSEOVER ] = D3DCOLOR_ARGB( 255, 0, 0, 0 );

 // Assign the Element
 SetDefaultElement( DXUT_CONTROL_ARROWBUTTON, 0, &Element );

 //-------------------------------------
 // - Fill layer划过时的图片
 //-------------------------------------
 SetRect( &rcTexture, 380, 20, 490, 54 );
 Element.SetTexture( 0, &rcTexture, D3DCOLOR_ARGB( 0, 255, 255, 255 ) );
 Element.TextureColor.States[ DXUT_STATE_MOUSEOVER ] = D3DCOLOR_ARGB( 160, 255, 255, 255 );
 Element.TextureColor.States[ DXUT_STATE_PRESSED ] = D3DCOLOR_ARGB( 60, 0, 0, 0 );
 Element.TextureColor.States[ DXUT_STATE_FOCUS ] = D3DCOLOR_ARGB( 30, 255, 255, 255 );

 // Assign the Element
 SetDefaultElement( DXUT_CONTROL_ARROWBUTTON, 1, &Element );//DXUT_CONTROL_ARROWBUTTON在DXUTgui.h的enum DXUT_CONTROL_TYPE中添加

 

使用自己控件图片

在SimpleSample.cpp中的void InitApp()中添加代码如下

    g_SettingsDlg.Init( &g_DialogResourceManager );//原有代码
    g_HUD.Init( &g_DialogResourceManager );//原有代码
    g_SampleUI.Init( &g_DialogResourceManager );//原有代码

    g_DialogResourceManager.AddControlsTexture(L"tomb.dds");//控件图片

    g_HUD.AddArrowButton( IDC_TEMPGRAPH, L"曲 线 图",730, 70, 100, 50, 0,true);
