Q:如何在對話框中加入工具條
在 OnInitDialog 中加入下面代碼：
BOOL CYourDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Create the toolbar. To understand the meaning of the styles used, you
// can take a look at the MSDN for the Create function of the CToolBar class.
ToolBar.Create(this, WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_TOOLTIPS |CBRS_FLYBY | CBRS_BORDER_BOTTOM);
// I have assumed that you have named your toolbar''s resource as IDR_TOOLBAR1.
// If you have given it a different name, change the line below to accomodate
// that by changing the parameter for the LoadToolBar function.
ToolBar.LoadToolBar(IDR_TOOLBAR1);
CRect rcClientStart;
CRect rcClientNow;
GetClientRect(rcClientStart);
// To reposition and resize the control bar
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST,0, reposQuery, rcClientNow);
CPoint ptOffset(rcClientNow.left - rcClientStart.left,rcClientNow.top-rcClientStart.top);
CRect rcChild;
CWnd* pwndChild = GetWindow(GW_CHILD);
while (pwndChild)
{
pwndChild->GetWindowRect(rcChild);
ScreenToClient(rcChild);
rcChild.OffsetRect(ptOffset);
pwndChild->MoveWindow(rcChild, FALSE);
pwndChild = pwndChild->GetNextWindow();
}
CRect rcWindow;
GetWindowRect(rcWindow);
rcWindow.right += rcClientStart.Width() - rcClientNow.Width();
rcWindow.bottom += rcClientStart.Height() - rcClientNow.Height();
MoveWindow(rcWindow, FALSE);
// And position the control bars
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);
return TRUE; // return TRUE unless you set the focus to a control
}
Q:如何改變對話框的形狀？
可用下面一些函數：
CreatePolygonRgn
CreateRectRgn
CreateRoundRectRgn 等.
CRgn m_rgn; // Put this in your dialog''s header file. i.e. a member variable
// This Gets the size of the Dialog: This piece of code is to be placed in the
// OnInitDialog Function of your dialog.
CRect rcDialog
GetClientRect(rcDialog);
// The following code Creates the area and assigns it to your Dialog
m_rgn.CreateEllipticRgn(0, 0, rcDialog.Width(), rcDialogHeight());
SetWindowRgn(GetSafeHwnd(), (HRGN) m_rgn, TRUE);
Q：如何實現非客戶區移動？
可用下面二種方法
// Handler for WM_LBUTTONDOWN message
void CYourDialog::OnLButtonDown(UINT nFlags, CPoint point)
{
CDialog::OnLButtonDown(nFlags, point);
PostMessage( WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM( point.x, point.y));
}
// Handler for WM_NCHITTEST message
LONG CYourDialog::OnNcHitTest( UINT uParam, LONG lParam )
{
int xPos = LOWORD(lParam);
int yPos = HIWORD(lParam);
UINT nHitTest = CDialog::OnNcHitTest(CSize(xPos, yPos));
return (nHitTest == HTCLIENT) ? HTCAPTION : nHitTest;
}
Q:如何使對話框初始為最小化狀態？
在 OnInitDialog 中加入下面代碼：
SendMessage(WM_SYSCOMMAND, SC_MAXIMIZE, NULL);
Q:如何限定對話框大小范圍？
在 WM_SIZING中加入下面代碼：
void CYourDialog::OnSizing(UINT fwSide, LPRECT pRect)
{
if(pRect->right - pRect->left <=200)
pRect->right = pRect->left + 200;
if(pRect->bottom - pRect->top <=200)
pRect->bottom = pRect->top + 200;
CDialog::OnSizing(fwSide, pRect);
}
Q:如何在對話框中加入狀態條？
定義 CStatusBar 變量：
CStatusBar m_StatusBar;
定義狀態條指定狀態：
static UINT BASED_CODE indicators[] =
{
ID_INDICATOR_CAPS,
ID_INDICATOR_NUM
};
在 OnInitDialog 中加入下面代碼：
m_StatusBar.CreateEx(this,SBT_TOOLTIPS,WS_CHILD|WS_VISIBLE|CBRS_BOTTOM,AFX_IDW_STATUS_BAR);
// Set the indicators namely caps and nums lock status
m_StatusBar.SetIndicators(indicators,sizeof(indicators)/sizeof(UINT));
CRect rect;
GetClientRect(&rect);
m_StatusBar.SetPaneInfo(0,ID_INDICATOR_CAPS,SBPS_NORMAL,rect.Width()/2);
m_StatusBar.SetPaneInfo(1,ID_INDICATOR_NUM,SBPS_STRETCH ,rect.Width()/2);
RepositionBars(AFX_IDW_CONTROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,ID_INDICATOR_NUM);
m_StatusBar.GetStatusBarCtrl().SetBkColor(RGB(180,180,180));
