动态生成控件(CButton, CComboBox, CTreeCtrl, CListCtrl, CTabCtrl, CEdit)、字体设置、常见设置

一、动态生成控件

1.CButton

   Create(_T("查询"), WS_CHILD|BS_PUSHBUTTON, rect, this, 1);

2.CComboBox

   Create(WS_CHILD|WS_VISIBLE|WS_VSCROLL|CBS_DROPDOWNLIST, rect, this, 1);

3.CTreeCtrl

   Create(WS_VISIBLE | TVS_HASBUTTONS | TVS_HASLINES | TVS_LINESATROOT | WS_TABSTOP | TVS_INFOTIP | TVS_SHOWSELALWAYS, rect, this, 1);

4.CListCtrl

    Create(WS_CHILD|WS_BORDER|LVS_REPORT|LVS_SHOWSELALWAYS|LVS_SINGLESEL, rect, this, 1);

    SetExtendedStyle(LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES | LVS_EX_TRACKSELECT);

5.CTabCtrl

    Create(TCS_TABS | TCS_FIXEDWIDTH | WS_CHILD | TCS_HOTTRACK | TCS_SINGLELINE | TCS_RAGGEDRIGHT | WS_EX_NOPARENTNOTIFY, rect, this, 1);

6.CEdit

    Create(WS_CHILD | WS_TABSTOP | WS_BORDER | ES_AUTOHSCROLL, rect, this, 1);

二、字体设置

1.创建对象（对象必须：在.h文件中，或者声明为全局变量）

   CFont m_font;

2.创建字体

   两种方式：

 （1）m_font.CreateFont(
           12,                        // nHeight
           0,                         // nWidth
           0,                         // nEscapement
           0,                         // nOrientation
           FW_BOLD,                   // nWeight
           FALSE,                     // bItalic
           FALSE,                     // bUnderline
           0,                         // cStrikeOut
           ANSI_CHARSET,              // nCharSet
           OUT_DEFAULT_PRECIS,        // nOutPrecision
           CLIP_DEFAULT_PRECIS,       // nClipPrecision
           DEFAULT_QUALITY,           // nQuality
           DEFAULT_PITCH | FF_SWISS,  // nPitchAndFamily
           "宋体");
  （2）m_font.CreatePointFont(87, "宋体_GB2312");

3.设置控件字体

   控件对象->SetFont(&m_font);

三、常见设置

1.CComboBox下拉List的宽度，使其根据列表中的字体长度变化。

void CMyTabCtrl::SetComboBoxDropDownWidth(CMyComboBox* pComboBox)
{
 int      dx = 0;
 TEXTMETRIC   tm;
 CDC*      pDC = pComboBox->GetDC();
 CFont*      pFont = pComboBox->GetFont();

 // Select the listbox font, save the old font
 CFont* pOldFont = pDC->SelectObject(pFont);
 // Get the text metrics for avg char width
 pDC->GetTextMetrics(&tm);

 for (int i = 0; i < pComboBox->GetCount(); ++i)
 {
  CString str;
  pComboBox->GetLBText(i, str);
  CSize sz = pDC->GetTextExtent(str);

  // Add the avg width to prevent clipping
  sz.cx += tm.tmAveCharWidth;

  if (sz.cx > dx)
   dx = sz.cx;
 }
 // Select the old font back into the DC
 pDC->SelectObject(pOldFont);
 pComboBox->ReleaseDC(pDC);

 // Adjust the width for the vertical scroll bar and the left and right border.
 dx += ::GetSystemMetrics(SM_CXVSCROLL) + 2*::GetSystemMetrics(SM_CXEDGE);

 // Set the width of the list box so that every item is completely visible.
 pComboBox->SetDroppedWidth(dx);
}

2.控件位置

  一般控件：SetWindowPos(NULL, x, y, cx, cy, 0);

 CComboBox控件：SetWindowPos(NULL, x, y, cx, 80, 0); // 这里的80是下拉框的高度
