1.工具條和狀態(tài)條中控件的添加：
方法⑴.只能在ToolBar里創(chuàng)建控件：首先，在ToolBar中創(chuàng)建一個(gè)Button，其ID為ID_TOOL_COMBO(我們要將創(chuàng)建的控件放在該Button的位置上).
其次，新創(chuàng)建一個(gè)類CMainToolBar，要從CToolBar繼續(xù)(創(chuàng)建過(guò)程大概如下：選擇工程/增加到工程/新的類；也可以選擇工程的根，然后點(diǎn)擊右鍵，選擇新的類；或者CTL W，選擇增加類/新的類 --- 然后在class type里選擇Generic Class，在Name欄里輸入新類的名字，Base class里輸入CToolBar),創(chuàng)建成功后在該類里創(chuàng)建要增加的控件的對(duì)象，如：
CComboBox m_wndMyCombo;
CStatic m_wndCategory, m_wndCategoryPath;
CButton m_wndOpenButton;
Cedit m_wndEdit;
然后在構(gòu)造函數(shù)里初始化如：
m_wndMyCombo.m_hWnd = NULL;
m_wndCategory.m_hWnd = NULL;
m_wndCategoryPath.m_hWnd = NULL;
m_wndOpenButton.m_hWnd = NULL;
m_wndEdit.m_hWnd = NULL;
接著在CMainframe的頭文件里創(chuàng)建CMainToolBar的一個(gè)對(duì)象m_wndToolBar，最后在.cpp文件的OnCreate函數(shù)的最后實(shí)現(xiàn)如下：
int index = 0;
CRect rect; // 可定義在頭文件當(dāng)中
// ComboBox
{
//找到指定的工具項(xiàng)
while(m_wndToolBar.GetItemID(index)!=ID_TOOL_COMBO)
index ;
//設(shè)置指定工具項(xiàng)的寬度并獲取新的區(qū)域 120是寬度
m_wndToolBar.SetButtonInfo(index, ID_TOOL_COMBO, TBBS_SEPARATOR, 120);
m_wndToolBar.GetItemRect(index, &rect);
//設(shè)置位置
rect.top =1;
rect.bottom = 200;
// 創(chuàng)建并顯示控件
if(!m_wndToolBar.m_wndMyCombo.Create(WS_CHILD|WS_VISIBLE| CBS_AUTOHSCROLL|
CBS_DROPDOWNLIST | CBS_HASSTRINGS , rect, &m_wndToolBar, ID_TOOL_COMBO))
{
TRACE0("Failed to create combo-box\n");
return FALSE;
}
m_wndToolBar.m_wndMyCombo.ShowWindow(SW_SHOW);
//填充內(nèi)容
m_wndToolBar.m_wndMyCombo.AddString("25%");
m_wndToolBar.m_wndMyCombo.AddString("50%");
m_wndToolBar.m_wndMyCombo.AddString("75%");
//選擇默認(rèn)項(xiàng)
m_wndToolBar.m_wndMyCombo.SetCurSel(0);
//獲取到內(nèi)容并MSGBOX顯示出來(lái)
CString strContent;
m_wndToolBar.m_wndMyCombo.GetWindowText(strContent);
index = 0;
}
其他控件都類似創(chuàng)建(只需要注重一下各自的Create函數(shù)的參數(shù)即可)。
方法⑵.這種方法創(chuàng)建不太輕易控制：直接在CMainframe的頭文件中創(chuàng)建要增加的控件的對(duì)象，如CButton 的對(duì)象m_wndAboutButton，然后創(chuàng)建CToolBar或者CstatusBar的對(duì)象，如：CstatusBar的對(duì)象_wndStatusBar；再增加幾個(gè)函數(shù)如下：
Protected:
virtual void RecalcLayout(BOOL bNotify = TRUE);
afx_msg void CMainFrame::OnViewStatusBar();
接著在.cpp文件中將StatusBar的ID和OnViewStatusBar 函數(shù)綁定在一起，如下所示：BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
// {{AFX_MSG_MAP(CMainFrame)
ON_COMMAND(ID_VIEW_STATUS_BAR, OnViewStatusBar)
ON_WM_CREATE()
// }}AFX_MSG_MAP
END_MESSAGE_MAP()
然后Create函數(shù)的最后(返回值之前)實(shí)現(xiàn)如下代碼：
CRect rc;
VERIFY(m_wndAboutButton.Create(_T("MyAbout"),
WS_VISIBLE,rc,this,ID_APP_ABOUT));
// TODO: Remove this if you don't want tool tips or a resizeable toolbar
m_wndToolBar.SetBarStyle(m_wndToolBar.GetBarStyle() |
CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC);
再在RecalcLayout函數(shù)里實(shí)現(xiàn)：
CRect rc;
if (m_wndStatusBar.m_hWnd)
{
m_wndStatusBar.GetWindowRect(&rc);
ScreenToClient(&rc);
rc.right -= 50;
m_wndStatusBar.SetWindowPos(NULL,rc.left,rc.top,rc.Width(),rc.Height(),
SWP_NOZORDER);
rc.left = rc.right;
rc.right = 50;
m_wndStatusBar.SetWindowPos(NULL,rc.left,rc.top,rc.Width(),rc.Height(),
SWP_NOZORDER);
}
最后在OnViewStatusBar()里實(shí)現(xiàn)：
BOOL bShow = m_wndStatusBar.GetStyle() & WS_VISIBLE;
m_wndAboutButton.SetWindowPos(NULL, 0, 0, 0, 0, SWP_NOZORDER|SWP_NOMOVE|SWP_NOSIZE|SWP_NOACTIVATE|
(bShow ? SWP_SHOWWINDOW : SWP_HIDEWINDOW));
ToolBar中的創(chuàng)建與此相同，只需更改一下句柄即可
2.使工具條上的按鈕點(diǎn)擊一次為按下，再點(diǎn)擊才彈起
bCheck=m_RtfEditToolBar.GetToolBarCtrl().IsButtonChecked(ID_TB_BOLD);
m_RtfEditToolBar.GetToolBarCtrl().CheckButton(ID_TB_BOLD, !bCheck);
3.如何隱藏工具欄
添加如下兩個(gè)函數(shù)
隱藏：
void CMainFrame::OnHide()
{
if(m_wndToolBar.IsWindowVisible())
m_wndToolBar.ModifyStyle(WS_VISIBLE,0);
SendMessage(WM_SIZE);
}
顯示：
void CMainFrame::OnShow()
{
if(!m_wndToolBar.IsWindowVisible())
m_wndToolBar.ModifyStyle(0,WS_VISIBLE);
SendMessage(WM_SIZE);
}
4.如何動(dòng)態(tài)獲取工具條指針并給工具條加標(biāo)題?
[問(wèn)題提出]
工具條也是窗口,是窗口就有標(biāo)題,如何給工具條加標(biāo)題?
[程序?qū)崿F(xiàn)]
不想動(dòng)態(tài)改變工具條的標(biāo)題就在CMainFrame::OnCreate()中:
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
......
m_wndToolBar.SetWindowText(_T("Standdard"));
return 0;
}
若想動(dòng)態(tài)改變工具條的標(biāo)題,如下:
聲明一個(gè)菜單,并響應(yīng)事件,如響應(yīng):OnMyToolBar()函數(shù)
void CMainFrame::OnMyToolBar()
{
// TODO: Add your command handler code here
CToolBar *pToolBar = (CToolBar *)AfxGetMainWnd()->GetDescendantWindow(AFX_IDW_TOOLBAR);
pToolBar->SetWindowText (_T("Standdard"));
}
不要在TooBar懸浮時(shí)做OnMyToolBar()會(huì)出錯(cuò)的.
順便提一下如何獲得狀態(tài)條的指針:
CStatusBar * pStatusBar =(CStatusBar *)AfxGetMainWnd()->GetDescendantWindow(AFX_IDW_STATUS_BAR);
5.在狀態(tài)條中顯示鼠標(biāo)的設(shè)備坐標(biāo)與邏輯坐標(biāo)
顯示器的設(shè)備坐標(biāo)系的原點(diǎn)在客戶區(qū)的左上角，x軸向右增長(zhǎng)，y軸向下增長(zhǎng)。我們要設(shè)置的邏輯坐標(biāo)系的原點(diǎn)則在客戶區(qū)的中心，x軸向右增長(zhǎng)，y軸向上增長(zhǎng)，如一個(gè)笛卡爾坐標(biāo)系一般。
為CChildView添加一個(gè)成員函數(shù)void OnPrepareDC(CDC * pDC, CPrintInfo * pInfo = NULL);
void OnPrepareDC(CDC * pDC, CPrintInfo * pInfo){
CRect rect;
// 設(shè)置映射模式為LOMETRIC (0.1mm)，右上為增長(zhǎng)方向
pDC->SetMapMode (MM_LOMETRIC);
// 將坐標(biāo)原點(diǎn)定在客戶區(qū)的中心
GetClientRect(rect);
pDC->SetViewportOrg(rect.Width()/2, rect.Height()/2);
}
為CChildView響應(yīng)鼠標(biāo)移動(dòng)消息，并在狀態(tài)條中顯示鼠標(biāo)的坐標(biāo)值。m_ptMouse數(shù)據(jù)成員是原打算做十字交叉線用的，在此使用沒(méi)有實(shí)際意義。
void CChildView::OnMouseMove(UINT nFlags, CPoint point){
CClientDC dc(this);
CString str;
OnPrepareDC(&dc);
//要訪問(wèn)類CMainFrame，需要將mainfrm.h文件引入
CMainFrame * pFrame = (CMainFrame *) AfxGetApp()->m_pMainWnd;
//要訪問(wèn)CMainFrame的數(shù)據(jù)成員m_wndStatusBar，需要手工修改mainfrm.h，public這個(gè)數(shù)據(jù)成員
CStatusBar * pStatus = (CStatusBar *) &pFrame->m_wndStatusBar;
m_ptMouse = point;
str.Format ("設(shè)備坐標(biāo) X=%i pixel, Y=%i pixel", m_ptMouse.x, m_ptMouse.y);
pStatus->SetPaneText(1, str);
dc.DPtoLP(&m_ptMouse);
str.Format ("邏輯坐標(biāo) X=%i * 0.1mm, Y=%i * 0.1mm", m_ptMouse.x, m_ptMouse.y);
pStatus->SetPaneText(2, str);
}
6.如何更新?tīng)顟B(tài)條上的現(xiàn)實(shí)內(nèi)容
By default, a CStatusBar pane is not enabled when the pane is created. To activate a pane, you must call the ON_UPDATE_COMMAND_UI() macro for each pane on the status bar and update the panes. Because panes do not send WM_COMMAND messages, you cannot use ClassWizard to activate panes; you must type the code manually. For example, suppose one pane has ID_INDICATOR_PAGE as its identifier and that it contains the current page number in a document. To make the ID_INDICATOR_PAGE pane display text, add the following to a header file (probably the MAINFRM.H file):
afx_msg void OnUpdatePage(CCmdUI *pCmdUI);
Add the following to the application message map:
ON_UPDATE_COMMAND_UI(ID_INDICATOR_PAGE, OnUpdatePage)
Add the following to a source code file (probably MAINFRM.CPP):
void CMainFrame::OnUpdatePage(CCmdUI *pCmdUI)
{
pCmdUI->Enable();
}
To display text in the panes, either call SetPaneText() or call CCmdUI::SetText() in the OnUpdate() function. For example, you might want to set up an integer variable m_nPage that contains the current page number. Then, the OnUpdatePage() function might read as follows:
void CMainFrame::OnUpdatePage(CCmdUI *pCmdUI)
{
pCmdUI->Enable();
char szPage[16];
wsprintf((LPSTR)szPage, "Page %d", m_nPage);
pCmdUI->SetText((LPSTR)szPage);
}
This technique causes the page number to appear in the pane during idle processing in the same manner that the application updates other indicators.
