mfc 控件使用的一些小问题

一、关于spin控件按钮上下增加数出现想反的情况

spin控件设定属性autobuddy和setbuddyinteger之后就会与最近的edit控件自动关联

然而会出现按上箭头减少，下箭头数增加的情况

解决该问题方法是：调用SetRange()函数就ok了

((CSpinButtonCtrl*)GetDlgItem(IDC_SPIN))->SetRange(0,100);

二、用函数获取控件checkbox按钮的选定状态，用GetCheck函数出错

正确调用：

intcheck=(（CButton*）GetDlgItem(IDC_CHECK))->GetCheck();就ok了

check的值可能为0、1、2；

三、树形控件CTreeViewCtrl

//添加父项和子项
//treectrlconstintDeptCount=4;

CStringCompName=_T("父项");

CStringTreeHeader[DeptCount]={_T("子项1"),_T("子项2"),_T(“子项3"),_T("子项4")};

HTREEITEMhTreeItem[DeptCount];

HTREEITEMhComp;

hComp=m_tree.InsertItem(CompName);

for(i=0;i<DeptCount;++i){hTreeItem[i]=m_tree.InsertItem(TreeHeader[i],hComp);

m_tree.SetItemData(hTreeItem[i],(DWORD)(20+i));

//设置每个子项对应的值}

////获取每个子项的值

HTREEITEMSelItem;

SelItem=m_Tree.GetSelectedItem();//所选择的项

DWORDw=m_Tree.GetItemData(SelItem);//w为20为子项121为子项2

为树形控件添加图标

m_imgTree.Create(16,16,ILC_COLOR4|ILC_MASK,4,1);
m_imgTree.Add(AfxGetApp()->LoadIcon(IDI_ICON_TREE_DEPT));
m_imgTree.Add(AfxGetApp()->LoadIcon(IDI_ICON_TREE_DEPTSEL));
m_imgTree.Add(AfxGetApp()->LoadIcon(IDI_ICON_TREE_PEOPLE));
m_imgTree.Add(AfxGetApp()->LoadIcon(IDI_ICON_TREE_PEOPLESEL));

m_tree.SetImageList(&m_imgTree,TVSIL_NORMAL);
InsertNodeToTree(TVI_ROOT,CDeptTree::GetInstance().GetDept(0));

m_tree.Expand(m_tree.GetRootItem(),TVE_EXPAND);
HTREEITEMhChild=m_tree.GetNextItem(m_tree.GetRootItem(),TVGN_CHILD);
if(hChild)
{
m_hActive=hChild;
m_tree.SelectItem(m_hActive);
m_tree.SetItemImage(m_hActive,1,1);//图标的序号为添加时的序号
}
else
m_hActive=m_tree.GetRootItem();

四、CToolBar工具条的创建和图标的添加

//toolbar

m_toolbar.CreateEx(this,TBSTYLE_FLAT,WS_CHILD|WS_VISIBLE|CBRS_ALIGN_TOP|CBRS_ALIGN_ANY/*|CCS_NODIVIDER*/|CBRS_TOOLTIPS);

m_toolbar.LoadToolBar(IDR_TOOLBAR);

//工具条资源ID

UINTID[]={ID_TOOLBAR_1,ID_TOOLBAR_2,ID_SEPARATOR};

m_toolbar.SetButtons(ID,sizeof(ID)/sizeof(UINT));

m_toolbar.SetButtonText(0,_T("保存"));

m_toolbar.SetButtonText(1,_T("取消"));

m_imageList.Create(16,16,ILC_COLOR24|ILC_MASK,4,1);

//图标大小，颜色值，初始化个数为4，默认增加数为1

m_imageList.Add(AfxGetApp()->LoadIcon(IDI_ICON_SAVE));

//加载图标资源

m_imageList.Add(AfxGetApp()->LoadIcon(IDI_ICON_CANCEL));

m_toolbar.GetToolBarCtrl().SetImageList(&m_imageList);

m_toolbar.GetToolBarCtrl().SetButtonSize(CSize(BUTTON_WIDTH,TOOLBAR_HEIGHT));

//设置工具条宽度和高度（常量）

m_toolbar.SetWindowPos(NULL,0,0,0,0,SWP_NOSIZE|SWP_SHOWWINDOW);

//设置工具条放置的位置

RepositionBars(AFX_IDW_CONTROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,0);//显示工具条

五、时间控件DateTimePIckerCtrl

CTimet1,t2;

用CTimeSpants=t1-t2;函数，得到两个时间的相差天数

//设置时间控件显示格式00:00((CDateTimeCtrl*)GetDlgItem(IDC_DATETIMEPICKER))->SetFormat(_T("HH:mm"));

可用classwizard为控件设置两个变量controlandvaluetype

////////////设置控件的初始值

COleDateTimetime;

CStringstrTime;

strTime.Format(_T("%s:00"),m_pClass->GetOnTime());

if(time.ParseDateTime(strTime))

{

((CDateTimeCtrl*)GetDlgItem(IDC_DATETIMEPICKER_ONWORK))->SetTime(time);

}

//////////设置控件时间日期的范围

COleDateTimet=COleDateTime::GetCurrentTime();

COleDateTimet1=COleDateTime(t.GetYear()-50,1,1,0,0,0);

COleDateTimet2=COleDateTime(t.GetYear()+50,12,GetDaysOfMonth(t.GetYear()+50,12),23,59,59);

((CDateTimeCtrl*)GetDlgItem(IDC_DATETIMEPICKER_OW_SD))->SetRange(&t1,&t2);

((CDateTimeCtrl*)GetDlgItem(IDC_DATETIMEPICKER_OW_ED))->SetRange(&t1,&t2);

六、ListCtrl控件

删除控件中的某一行后设置光标在下一行高亮显示：

m_ListCtrl.DeleteItem(nIndex);

deletepOver;

intitems=m_ListCtrl.GetItemCount();

nIndex=nIndex==items?items-1:nIndex;

m_ListCtrl.SetFocus();

m_ListCtrl.SetItemState(nIndex,LVIS_SELECTED|LVIS_FOCUSED,LVIS_SELECTED|LVIS_FOCUSED);

m_ListCtrl.EnsureVisible(nIndex,FALSE);

七、手动添加状态栏

#defineIDS_STRING_OPERATOR_NAME1
#defineIDS_INDICATOR_TIME2
#defineIDS_INDICATOR_RESERVE13
#defineIDS_INDICATOR_RESERVE24
#defineIDS_INDICATOR_RESERVE35
staticUINTindicators[]=
{
IDS_STRING_OPERATOR_NAME,
IDS_INDICATOR_TIME,
IDS_INDICATOR_RESERVE1,
IDS_INDICATOR_RESERVE2,
IDS_INDICATOR_RESERVE3
};

//加载状态栏
{
m_StausBar.Create(this);
m_StausBar.SetIndicators(indicators,sizeof(indicators)/sizeof(int));

m_StausBar.SetPaneInfo(0,IDS_STRING_OPERATOR_NAME,SBPS_NORMAL,160);//设置每一栏的宽度
m_StausBar.SetPaneInfo(1,IDS_INDICATOR_TIME,SBPS_NORMAL,160);
m_StausBar.SetPaneInfo(2,IDS_INDICATOR_RESERVE1,SBPS_NORMAL,30);
m_StausBar.SetPaneInfo(3,IDS_INDICATOR_RESERVE2,SBPS_NORMAL,40);
m_StausBar.SetPaneInfo(4,IDS_INDICATOR_RESERVE3,SBPS_STRETCH,0);

m_StausBar.SetPaneText(0,_T("操作员：系统管理员"));//设置文本
CTimet1=CTime::GetCurrentTime();
m_StausBar.SetPaneText(1,t1.Format("%Y-%m-%d%H:%M:%S"));

RepositionBars(AFX_IDW_CONTROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,IDS_INDICATOR_RESERVE3);
m_StausBar.ShowWindow(SW_SHOW);
SetTimer(1,1000,NULL);

}
