Win32怎么让一个应用存在多个WndProc(单独的窗口)

末影小末EnderMo 2020-07-23 03:21:49
想让应用内部多一个内置的文本编辑器,直接给它理解成多窗口吧.
但是主窗口(如下图)已近存在了,就是已经把窗口给注册了,那如何再多加一个内置窗口呢?

这是按钮"编辑器"的命令处理
case WM_COMMAND:

        {

            int wmId = LOWORD(wParam);

            // 分析菜单选择:

            switch (wmId)

            {

            case IDM_EXIT:

                DestroyWindow(hWnd);

                break;

            case IDC_BUTTON:

                MessageBox(NULL, NULL, NULL, NULL);

                //打开文本编辑器

            default:

                return DefWindowProc(hWnd, message, wParam, lParam);

            }

        }

        break;

目标:点击"编辑器",运行以下代码
下面是文本编辑器的代码(WINAPI)
LRESULT CALLBACK EditProc(HWND, UINT, WPARAM, LPARAM);

#define BUFFER(x,y) *(pBuffer + y * cxBuffer + x)

辛苦你了,但不是这一个意思 因为我把这个窗口单独放在一个头文件里面,意思就是点击"编辑器"按钮的时候,从这个头文件的TextEdit函数显示窗口 不一定要消息循环 从头说起,这是之前一个类似于当前工程的代码 辛苦一下,看一下这个代码吧

}

#define D_TipBox TipBox
如上的代码 使用TipBox(NULL,"文字","标题",NULL);就可以显示如下窗口了 但是这个是基于对话框的 但我现在想用我13楼发的代码做一个文本编辑器,用一个新的窗口(什么样的都好,但是不要用通用控件,在对话框实现那串代码也好) 可以做出来吗

#define WS_VISIBLE 0x10000000L 没有 ？ ShowWindow（SW_SHOW);
SW_SHOW还是显示不了 是要把LRESULT换成INT_PTR?

代码已经在帖子上面了,只需要讨论怎么显示这个窗口 那这样的话 如上代码,改为 
int Tip TextEdit(
    HWND hWnd,          // handle 
    LPWSTR lpText,     // text 
    LPWSTR lpCaption,  // title 
    UINT uType          // style

        MAKEINTRESOURCE(IDD_TIPBOX), NULL, DialogProc1, (LPARAM)&mmb);
*/
    return -1;
}
就是用CreateWindow(szAppName, TEXT("Typing Program") 替换掉DialogParam就可以了吗

wndclass.lpfnWndProc = xxxxxxProc; wndclass.lpszClassName = xxxxxx 注册类的时候指定不同的 lpfnWndProc 和 lpszClassName, CreateWindow 的时候用这个注册的类名即可
意思也不是子窗口,是以条件显示的 比如点击按钮才显示 之前就是一个类似的内置窗口例子: 
typedef struct tagMMB
{// 
    HWND hWnd;          // handle 

    LPWSTR lpText;     // text 

    LPWSTR lpCaption;  //  title 

    UINT uType;         // style 

} MMB_PARAM;
//
BOOL CALLBACK DialogProc1(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    static HBITMAP hBitmap;                  // 1 静态变量
    static HBITMAP hBitmap2;
    static HBITMAP hBitmap3;
    static HFONT hFont;//定义静态字体变量
    BITMAP         bitmap;
    static HWND close;
    HDC hdcMem = NULL;
    static int      bmWidth, bmHeight;       // 2 静态变量
    char txt[40];
    MMB_PARAM* pmmb = (MMB_PARAM*)lParam;
    UNREFERENCED_PARAMETER(lParam);
    switch (uMsg)
    {
    case WM_INITDIALOG:
        SetWindowText(hwndDlg, pmmb->lpCaption);
        SetWindowText(GetDlgItem(hwndDlg, IDC_STATIC), pmmb->lpText);

int TipBox(

    MMB_PARAM mmb;
    mmb.hWnd = hWnd;
    mmb.lpText = lpText;
    mmb.lpCaption = lpCaption;
    mmb.uType = uType;
    DialogBoxParam((HINSTANCE)GetWindowLong(hWnd, GWL_HINSTANCE),
        MAKEINTRESOURCE(IDD_TIPBOX), NULL, DialogProc1, (LPARAM)&mmb);
    return -1;
}

#define D_TipBox TipBox
调用方法是 TipBox(NULL,"TXT","TITLE",NULL)即可 就是想像这个一样调用 只不过,上面那个是对话框,现在我想创建一个纯窗口而已

请问我需要在按下"编辑器"按钮的时候打开这个窗口,该如何做呢?

你也可以 用 对话框 （放一个 edit）。点击时 popup 出来
想多注册一个类的原因主要还是 通用对话框限制很大,WM_SIZE之类的消息处理不了,改变难度太大了... 所以才决定自己新创建一个窗体,和WindowProc一样进行改变,绘制. "总之,上面的代码是可以做成一个单独的exe的,只是想把这个代码合并到一个应用里面而已"
