我想在主窗口中创建一个小框,该框可以接受文本输入并包含按钮。当我说嵌入式时,我的意思是我希望它无缝集成在我的主窗口中,而没有自己的关闭按钮。我无休止地搜索了google,却没有找到不涉及mfc或.net的答案。如何在原始win32应用程序中执行此操作。请将您的代码添加到如下所示的我的骨架中。谢谢!
#include <windows.h>
LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;
int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR szCmdLine, int iCmdShow)
{
static TCHAR szAppName[] = TEXT ("App") ;
HWND hwnd ;
MSG msg ;
WNDCLASS wndclass ;
wndclass.style = CS_HREDRAW | CS_VREDRAW ;
wndclass.lpfnWndProc = WndProc ;
wndclass.cbClsExtra = 0 ;
wndclass.cbWndExtra = 0 ;
wndclass.hInstance = hInstance ;
wndclass.hIcon = LoadIcon (NULL, IDI_APPLICATION) ;
wndclass.hCursor = LoadCursor (NULL, IDC_ARROW) ;
wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH) ;
wndclass.lpszMenuName = NULL ;
wndclass.lpszClassName = szAppName ;
if (!RegisterClass (&wndclass))
{
MessageBox (NULL, TEXT ("This program requires Windows NT!"),
szAppName, MB_ICONERROR) ;
return 0 ;
}
hwnd = CreateWindow (szAppName, // window class name
TEXT ("App"), // window caption
WS_OVERLAPPEDWINDOW, // window style
CW_USEDEFAULT, // initial x position
CW_USEDEFAULT, // initial y position
CW_USEDEFAULT, // initial x size
CW_USEDEFAULT, // initial y size
NULL, // parent window handle
NULL, // window menu handle
hInstance, // program instance handle
NULL) ; // creation parameters
ShowWindow (hwnd, iCmdShow) ;
UpdateWindow (hwnd) ;
while (GetMessage (&msg, NULL, 0, 0))
{
TranslateMessage (&msg) ;
DispatchMessage (&msg) ;
}
return msg.wParam ;
}
LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
HDC hdc ;
PAINTSTRUCT ps ;
RECT rect ;
switch (message)
{
case WM_CREATE:
return 0 ;
case WM_PAINT:
hdc = BeginPaint (hwnd, &ps) ;
EndPaint (hwnd, &ps) ;
return 0 ;
case WM_DESTROY:
PostQuitMessage (0) ;
return 0 ;
}
return DefWindowProc (hwnd, message, wParam, lParam) ;
}
最佳答案
您想收到什么消息?
例如,当按下按钮时发送WM_COMMAND消息。按以下方式处理这些消息:
LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
HDC hdc ;
PAINTSTRUCT ps;
RECT rect ;
switch (message)
{
case WM_CREATE:
return 0 ;
case WM_COMMAND:
{
switch(LOWORD(wParam))
{
case IDC_BUTTON:
/*
IDC_BUTTON is id given to button
This id is specified while creating window. If you are using
CreateWindow then it will be as follows:
CreateWindow("BUTTON", 0, WS_CHILD|WS_VISIBLE, 70, 70, 80, 25, g_hWnd, (HMENU)IDC_BUTTON, hInst, 0);
and in resource.rc file or in the beginning of code. Do "#define IDC_BUTTON 3456"
3456 is just a reference you can give any other no as well. Prefer using bigger number so that they can not conflict with existing ones.
*/
//do whatever you want to do here when button is pressed
break
}
}
break;
case WM_PAINT:
hdc = BeginPaint (hwnd, &ps) ;
EndPaint (hwnd, &ps) ;
return 0 ;
case WM_DESTROY:
PostQuitMessage (0) ;
return 0 ;
}
return DefWindowProc (hwnd, message, wParam, lParam) ;
}
