矩形边框的三态按钮控件 CToolTipCtrl开发动态提示

本次只添加了与静态提示不同之处的代码

CMainDlg.h

#include "CLadderCtrl.h"

};

CMainDlg.cpp

设置动态文字的函数

BOOL CMainDlg::SetTipText(UINT id, NMHDR* pHdr, LRESULT* pResult){int nIndex = m_ladd.GetTrack();if (nIndex < 0 || nIndex >= m_ladd.GetItemCount())return FALSE;TOOLTIPTEXT* pText = (TOOLTIPTEXT*)pHdr;if (pText->uFlags & TTF_IDISHWND){auto nID = (int)pHdr->idFrom;CString str = m_ladd.GetItemText(nIndex);_tcscpy_s(pText->szText, 80, str);return TRUE;}return FALSE;return 0;
}

BOOL CMainDlg::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message){switch (pWnd->GetDlgCtrlID())	{case 8888:{static int nTrack = -1; // 用来看它是否切换 全局变量int n = m_ladd.GetTrack();if (nTrack !=n ){	 //切换算法nTrack = n;m_tip.Update();}}break;}return CDialogEx::OnSetCursor(pWnd, nHitTest, message);
}

CLadderCtrl.h

public:int GetTrack() const{return m_nTrack; //拿到你追踪到的是几号}CString GetItemText(int nIndex) const{return m_ds[nIndex]; //拿到的对应的索引来获取文字}CLadderCtrl();

CLadderCtrl.cpp

int CLadderCtrl::GetIndex(CPoint point)
{CClientDC dc(this);dc.SelectStockObject(DEFAULT_GUI_FONT);int i = -1, nCount = (int)m_ds.GetCount();CRect rect;GetClientRect(rect);CRect rc{ 0,0,0,rect.bottom };while (++i < nCount){CString str = m_ds[i];CSize size = dc.GetTextExtent(str);rc.right = rc.left + size.cx + rect.Height();dc.SelectObject(i == m_nIndex ? &m_brSel : &m_br);if (rc.PtInRect(point)){return i;}rc.left = rc.right;}return -1;
}

void CLadderCtrl::OnLButtonDown(UINT nFlags, CPoint point)  //和上面算法一致 这个用来算出位置
{int nIndex = GetIndex(point);if (nIndex != m_nIndex)  //去除无效点击 {m_nIndex = nIndex;Invalidate(FALSE);}CWnd::OnLButtonDown(nFlags, point);
}

void CLadderCtrl::OnMouseMove(UINT nFlags, CPoint point)

附录

CDC::FillSolidRect：无边框的纯色填充
GetSysColor获取系统常用的颜色。
GetStockObject（API） 获取系统预定义对象
CDC::SelectStockObject:选择系统预定义对象。
来自于API：GetStockObject

GDI对象的构造函数：CFile的构造函数
a)CPen的构造函数：
CPen(int nPenStyle, int nWidth, COLORREF crColor);
CPen pen;pen.CreatePen(PS_XXX...);
两句合成一句就是：CPen pen(PS_XXX...);b)CBrush的构造函数CBrush(COLORREF crColor);             // CreateSolidBrushCBrush(int nIndex, COLORREF crColor); // CreateHatchBrushexplicit CBrush(CBitmap* pBitmap);          // CreatePatternBrush

MouseMove 进入任意控件都不会理你 除非回到主窗口范围内
OnSetCursor 不论在什么控件都会显示出来 还可以switch getDlgCtrlID 任何控件都会执行
