我创建了一个简单的类来隐藏在 win32 API 中创建工具栏的细节，但我不喜欢它生成的工具栏。（请参阅图片以进行澄清。我没有声望点，所以我刚刚发布了一个链接）

我不知道现在黑色背景正在进入我的应用程序。
这是文件 CToolBar.h 中的类声明
#ifndef _CTOOLBAR_H
#define _CTOOLBAR_H
#include<windows.h>
#include<commctrl.h>
class CToolBar
{
public:
CToolBar();//constructor
~CToolBar();//destructor
void AddButton(int iconID, int command);//add Both a button, its icon and its command ID
void Show();//display the toolbar
void Initialise(HINSTANCE hInst, HWND hParent);
protected:
HINSTANCE m_hInst;
HWND m_hParent;
HWND m_hToolBar;
HIMAGELIST m_hImageList;
TBBUTTON m_Tbb[4]; //toolbar buttons
int m_numberButtons;
};
#endif
这是文件 CToolBar.cpp 中的实现
//CToolBar.cpp
#include "CToolBar.h"
#include<windows.h>
#include<commctrl.h>
CToolBar::CToolBar()//the constructor
{
m_hImageList=ImageList_Create(32, 32, ILC_COLOR32, 0, 15);//returns NULL if the function fails
//finish other initialisations
InitCommonControls();//initialise commctrl.dll whatever.. or else your toolbar wont appear
}
void CToolBar::Initialise(HINSTANCE hInst, HWND hParent)
{
m_hInst=hInst;
m_hParent=hParent;
m_hToolBar=CreateWindowEx(
WS_EX_PALETTEWINDOW ,
TOOLBARCLASSNAME,
"",
WS_CHILD | WS_CLIPCHILDREN | WS_CLIPSIBLINGS |WS_VISIBLE|TBSTYLE_BUTTON | TBSTYLE_TOOLTIPS | CCS_ADJUSTABLE | CCS_TOP ,
0, 0,
0, 0,
m_hParent,
NULL,
m_hInst,
0);
}
CToolBar::~CToolBar()//destructor
{
ImageList_Destroy(m_hImageList);
}
void CToolBar::AddButton(int iconID, int command)
{
HICON hIcon = LoadIcon(m_hInst, MAKEINTRESOURCE(iconID));
ImageList_AddIcon(m_hImageList, hIcon);
DeleteObject(hIcon);
if(iconID!= -1)//-1 means the separator. The rest are mere buttons
{
m_Tbb[m_numberButtons].iBitmap =m_numberButtons;
m_Tbb[m_numberButtons].idCommand = command;
m_Tbb[m_numberButtons].fsState = TBSTATE_ENABLED;
m_Tbb[m_numberButtons].fsStyle = TBSTYLE_BUTTON;
m_Tbb[m_numberButtons].dwData = 0;
m_Tbb[m_numberButtons].iString = 0;
}
else//ie if (iconID== -1) ; then display the separator. the command value is ignored
{
m_Tbb[m_numberButtons].iBitmap =-1;
m_Tbb[m_numberButtons].idCommand = 0;
m_Tbb[m_numberButtons].fsState = TBSTATE_ENABLED;
m_Tbb[m_numberButtons].fsStyle = TBSTYLE_SEP;
m_Tbb[m_numberButtons].dwData = 0;
m_Tbb[m_numberButtons].iString = 0;
}
m_numberButtons++;
}
void CToolBar::Show()
{
SendMessage(m_hToolBar, TB_SETIMAGELIST , (WPARAM)0, (LPARAM)m_hImageList);
SendMessage(m_hToolBar, TB_BUTTONSTRUCTSIZE, sizeof(TBBUTTON), 0);//message for backward
//compatibility
SendMessage(m_hToolBar, TB_ADDBUTTONS, m_numberButtons, (LPARAM)m_Tbb);
SendMessage(m_hToolBar,WM_SIZE,0,0);
ShowWindow(m_hToolBar, SW_SHOW);
}
我如何使用
main.cpp 中的类，我创建了该类的全局实例。
CToolBar myToolBar;
在回调过程中，在 WM_CREATE 下，我使用了一些成员函数。
case WM_CREATE:
myToolBar.Initialise(g_hInst,hwnd);
myToolBar.AddButton(IDI_OPEN, ID_OPEN);
myToolBar.AddButton(IDI_MAIN,ID_OPEN);//Separator button
myToolBar.AddButton(IDI_CLOSE, ID_CLOSE);
myToolBar.AddButton(IDI_CLOSEALL, ID_CLOSE);
myToolBar.Show();
break;
就是这样。
