CustomUI Direct3D9_Sample

刚开始建这个项目的时候编译器报了很多Link2019的错误。

后来添加了一些lib文件才解决，参考 缺少.lib文件导致的Link2019 解决方案汇总

Dialog::InitDefaultElements()

创建各种Element(元素，组成Control的单元)，放到CDXUTElementHolder类型的Dialog::m_DefaultElements中.

1 struct DXUTElementHolder
2 {
3     UINT nControlType;
4     UINT iElement;
5 
6     CDXUTElement Element;
7 };

m_DefaultElements存放的ElementHolder根据所属控件的类型（nControlType）从小到大(0开始)编号

 1 //-------------------------------------
 2     // CDXUTButton - Button
 3     //-------------------------------------
 4     SetRect( &rcTexture, 0, 0, 136, 54 );
 5     Element.SetTexture( 0, &rcTexture );
 6     Element.SetFont( 0 );
 7     Element.TextureColor.States[ DXUT_STATE_NORMAL ] = D3DCOLOR_ARGB( 150, 255, 255, 255 );
 8     Element.TextureColor.States[ DXUT_STATE_PRESSED ] = D3DCOLOR_ARGB( 200, 255, 255, 255 );
 9     Element.FontColor.States[ DXUT_STATE_MOUSEOVER ] = D3DCOLOR_ARGB( 255, 0, 0, 0 );
10 
11     // Assign the Element
12     SetDefaultElement( DXUT_CONTROL_BUTTON, 0, &Element );
13 
14 
15     //-------------------------------------
16     // CDXUTButton - Fill layer
17     //-------------------------------------
18     SetRect( &rcTexture, 136, 0, 252, 54 );
19     Element.SetTexture( 0, &rcTexture, D3DCOLOR_ARGB( 0, 255, 255, 255 ) );
20     Element.TextureColor.States[ DXUT_STATE_MOUSEOVER ] = D3DCOLOR_ARGB( 160, 255, 255, 255 );
21     Element.TextureColor.States[ DXUT_STATE_PRESSED ] = D3DCOLOR_ARGB( 60, 0, 0, 0 );
22     Element.TextureColor.States[ DXUT_STATE_FOCUS ] = D3DCOLOR_ARGB( 30, 255, 255, 255 );
23 
24 
25     // Assign the Element
26     SetDefaultElement( DXUT_CONTROL_BUTTON, 1, &Element );

这段代码定义了两个Button类型的Element，编号为0和1。

如果继续添加的话编号递增。

添加另一种类型的话，编号重新从零开始。

CDXUTControl::SetElement

 1 HRESULT CDXUTControl::SetElement( UINT iElement, CDXUTElement* pElement )
 2 {
 3     HRESULT hr = S_OK;
 4 
 5     if( pElement == NULL )
 6         return E_INVALIDARG;
 7     
 8     //m_DefaultElements中的元素同类型编号按从小到大的顺序排列
 9     //所以从m_DefaultElements中挑选出来的pElement的编号iElement递增（0,1,2.....）
10     //某一种控件第一次调用此函数（SetElement）时，控件的m_Elements为空，将编号为0的Element存入，循环退出
11     // Make certain the array is this large
12     for( UINT i = m_Elements.GetSize(); i <= iElement; i++ )
13     {
14         CDXUTElement* pNewElement = new CDXUTElement();
15         if( pNewElement == NULL )
16             return E_OUTOFMEMORY;
17 
18         hr = m_Elements.Add( pNewElement );
19         if( FAILED( hr ) )
20         {
21             SAFE_DELETE( pNewElement );
22             return hr;
23         }
24     }
25 
26     // Update the data
27     CDXUTElement* pCurElement = m_Elements.GetAt( iElement );
28     *pCurElement = *pElement;
29 
30     return S_OK;
31 }

===================================================================================================

Element的定义如下

 1 class CDXUTElement
 2 {
 3 public:
 4     void    SetTexture( UINT iTexture, RECT* prcTexture, D3DCOLOR defaultTextureColor = D3DCOLOR_ARGB( 255, 255, 255,
 5                                                                                                        255 ) );
 6     void    SetFont( UINT iFont, D3DCOLOR defaultFontColor = D3DCOLOR_ARGB( 255, 255, 255,
 7                                                                             255 ), DWORD dwTextFormat = DT_CENTER |
 8                      DT_VCENTER );
 9 
10     void    Refresh();
11 　　//纹理， 文本字体， 文本格式，  
12     UINT iTexture;          // Index of the texture for this Element 
13     UINT iFont;             // Index of the font for this Element
14     DWORD dwTextFormat;     // The format argument to DrawText 
15 　　// 放纹理的边界矩形
16     RECT rcTexture;         // Bounding rect of this element on the composite texture
17 　　//纹理和文本的Blend颜色， Blend分量用于控制透明度
18     DXUTBlendColor TextureColor;
19     DXUTBlendColor FontColor;
20 };

======================================================================================================

可以使用输入法(Input Method Editor)的IMEEditBox

 1 //已经定义了g_SampleUI
 2     CDXUTDialog                 g_SampleUI;             // dialog for sample specific controls
 3     g_SampleUI.Init( &g_DialogResourceManager );
 4     g_SampleUI.SetCallback( OnGUIEvent );
 5 // IME-enabled edit box
 6     CDXUTIMEEditBox* pIMEEdit;
 7     CDXUTIMEEditBox::InitDefaultElements( &g_SampleUI );
 8     if( SUCCEEDED( CDXUTIMEEditBox::CreateIMEEditBox( &g_SampleUI, IDC_EDITBOX2,
 9                                                       L"IME-capable edit control with custom styles. Type and press Enter", 20, 390, 600, 45, false, &pIMEEdit ) ) )
10     {
11         g_SampleUI.AddControl( pIMEEdit );
12         pIMEEdit->GetElement( 0 )->iFont = 1;
13         pIMEEdit->GetElement( 1 )->iFont = 1;
14         pIMEEdit->GetElement( 9 )->iFont = 1;
15         pIMEEdit->GetElement( 0 )->TextureColor.Init( D3DCOLOR_ARGB( 128, 255, 255, 255 ) );  // Transparent center
16         pIMEEdit->SetBorderWidth( 7 );
17         pIMEEdit->SetTextColor( D3DCOLOR_ARGB( 255, 64, 64, 64 ) );
18         pIMEEdit->SetCaretColor( D3DCOLOR_ARGB( 255, 64, 64, 64 ) );
19         pIMEEdit->SetSelectedTextColor( D3DCOLOR_ARGB( 255, 255, 255, 255 ) );
20         pIMEEdit->SetSelectedBackColor( D3DCOLOR_ARGB( 255, 40, 72, 72 ) );
21     }

CDXUTIMEEditBox继承自CDXUTEditBox，定义在DXUTguiIME.h/cpp文件中

包含了静态函数:

static void             InitDefaultElements( CDXUTDialog* pDialog );

负责为该类定义所使用的Element(元素),并通过

HRESULT CDXUTDialog::SetDefaultElement( UINT nControlType, UINT iElement, CDXUTElement* pElement );

添加到所属Dialog的默认元素表（m_DefaultElements）中, 一共9个Element

Please refer to DXUTguiIME.h/cpp for more details .
