关于TabCtrole的问题,

[dycdyc123]

1.怎样使用TabCtrol生成叶面
其中的控件怎样安排?(visible 与unvisible)
2.怎样把视View的指定Rect区域拷贝到CDC MyDc 中??

[dycdyc123]

高手那里去了?

我不用VC做程序，不过我也从不用TabCtrol控件，太不好用，有好多好用的控件，功能比他强，如SSTAB，等

CTabCtrl* pTab=(CTabCtrl*)GetDlgItem(IDC_TAB1);
pTab->InsertItem(0,"page1");
pTab->InsertItem(1,"page2");

Creating a CTabCtrl Application

--------------------------------------------------------------------------------

This article was contributed by Ben Hill.



Environment: VC6 SP3, NT4, Windows 2000 Pro, Windows 2000 Server

Firstly add the CMyTabCtrl.cpp and CMyTabCtrl.h to your project.

Using Visual Studio add a CTabCtrl control to your dialog. Add a member variable for this control as a CMyTabCtrl type not a simple CTabCtrl. CMyTabCtrl is derived from CTabCtrl.

You can simply add a CTabCtrl member variable and manually edit the file to become CMyTabCtrl

Now create dialogs for every page you require. These must be child dialogs with no border. Any controls here in these dialogs are handled by their own class.

Create a Class for each dialog. In the example these are CTabOne, CTabTwo and CTabThree.

In the CmyTabCtrl constructor you must add a ‘new’ for each page. Also in the Init function you must specify all tab dialogs to hide all but one

In this example the OnLButtonDown message handler is used to show and hide the various dialogs. The page is managed with a variable m_tabCurrent which holds the value of selected pages.

In the main app dialog’s OnInitDialog message handler add the tabs you require for your dialog. In this example these are ‘Tab One’, ‘Tab Two’ and ‘Tab Three’.

Functionality for the left and right cursor keys to select the tabs can be added in the CMyTabCtrl class.

CMyTabCtrl::CMyTabCtrl()
{
m_tabPages[0]=new CTabOne;
m_tabPages[1]=new CTabTwo;
m_tabPages[2]=new CTabThree;

m_nNumberOfPages=3;
}

CMyTabCtrl::~CMyTabCtrl()
{
for(int nCount=0; nCount < m_nNumberOfPages; nCount++){
delete m_tabPages[nCount];
}
}

void CMyTabCtrl::Init()
{
m_tabCurrent=0;

m_tabPages[0]->Create(IDD_TAB_ONE, this);
m_tabPages[1]->Create(IDD_TAB_TWO, this);
m_tabPages[2]->Create(IDD_TAB_THREE, this);

m_tabPages[0]->ShowWindow(SW_SHOW);
m_tabPages[1]->ShowWindow(SW_HIDE);
m_tabPages[2]->ShowWindow(SW_HIDE);

SetRectangle();
}

void CMyTabCtrl::SetRectangle()
{
CRect tabRect, itemRect;
int nX, nY, nXc, nYc;

GetClientRect(&tabRect);
GetItemRect(0, &itemRect);

nX=itemRect.left;
nY=itemRect.bottom+1;
nXc=tabRect.right-itemRect.left-1;
nYc=tabRect.bottom-nY-1;

m_tabPages[0]->SetWindowPos(&wndTop, nX, nY, nXc, nYc, SWP_SHOWWINDOW);
for(int nCount=1; nCount < m_nNumberOfPages; nCount++){
m_tabPages[nCount]->SetWindowPos(&wndTop, nX, nY, nXc, nYc, SWP_HIDEWINDOW);
}
}

void CMyTabCtrl::OnLButtonDown(UINT nFlags, CPoint point)
{
CTabCtrl::OnLButtonDown(nFlags, point);

if(m_tabCurrent != GetCurFocus()){
m_tabPages[m_tabCurrent]->ShowWindow(SW_HIDE);
m_tabCurrent=GetCurFocus();
m_tabPages[m_tabCurrent]->ShowWindow(SW_SHOW);
m_tabPages[m_tabCurrent]->SetFocus();
}
}

The Dialog Showing, Hiding and Drawing code is from the C++ Forum On this site. It was posted by someone whom I don't have name for.

If it was you then please let me know and I will have your name added

I hope this code is of some use. It has helped me to develop much more complex dialogs.
