Win32+API学习笔记：创建基本的窗口控件

创建一个标签

CreateWindowEx(0, "static", "姓名：",
                                            WS_CHILD | WS_VISIBLE | SS_NOTIFY,
                                            12, // xpos
                                            414, // ypos
                                            90, //width
                                            21, //height
                                            hwnd_frame, (HMENU)id_lbl_name, g_hInstance,  NULL) ;

1. 如果一个Static控件带上了SS_NOTIFY属性，则会在父窗口里响应STN_CLICKED、STN_DBLCLK、STN_DISABLE 和STN_ENABLE四种消息。

2. id_lbl_name 是一个整型数字，起到标识符的作用。

创建一个单行文本框

hwnd_t_name = CreateWindowEx(WS_EX_CLIENTEDGE, "edit", "这里可以输入初始内容",
                                          WS_CHILD | WS_VISIBLE | ES_AUTOHSCROLL,
                                          100,   // xpos
                                          410,  // ypos
                                          461, //width
                                          21, //height
                                          hwnd_frame, (HMENU)id_t_name,   g_hInstance,   NULL);

1. 加上 ES_AUTOHSCROLL 属性，才能确保文本内容宽度超过文本框的宽度时，可以按键盘向右移动，达到显示全部内容的目地。

2. 更新文本框内容
SetWindowText(hwnd_t_name, "abcdefg");

3. 获取文本框内容
char name[1024];
GetWindowText(hwnd_t_name, name1024);

创建一个按钮

hwnd_b_source_folder =  CreateWindowEx(0, "button", "选择...",
                                           WS_CHILD | WS_VISIBLE, // | WS_DISABLED
                                           571, // xpos
                                           8, // ypos
                                           96, //width
                                           25, //height
                                           hwnd_frame, (HMENU)id_b_source_folder, g_hInstance,  NULL) ;

创建一个复选框

hwnd_ck_quality = CreateWindowEx(0, "button", "高",
                                     WS_CHILD | WS_VISIBLE | BS_AUTOCHECKBOX,
                                     21,   // xpos
                                     128,  // ypos
                                     68, //width
                                     19, //height
                                     hwnd_frame, (HMENU) id_ck_quality,   g_hInstance,   NULL);

1. 其中 "button" + BS_AUTOCHECKBOX 表示为一个复选框

2. 判断一个复选框是否选中
   IsDlgButtonChecked(hwnd_frame, id_ck_quality)

创建一个下拉列表框

hwnd_c_image_quality = CreateWindowEx(0, "combobox", "Text",
                                          WS_CHILD | WS_VISIBLE |  CBS_DROPDOWNLIST,
                                          300,   // xpos
                                          69,  // ypos
                                          130, //width
                                          300, //height
                                          hwnd_frame, (HMENU)id_c_image_quality,   g_hInstance,   NULL);

1. 给 combobox 添加一项
void combobox_add_item(HWND hwnd_combobox, char *text)
{
    int index = (int)SendMessage(hwnd_combobox, CB_ADDSTRING, -1, (LPARAM)text);

    if(index == 0)
    {
        SendMessage(hwnd_combobox, CB_SETCURSEL, index, 0);
    }
}
 
2. 添加一项到下拉列表框
combobox_add_item(hwnd_c_image_quality, "高");
combobox_add_item(hwnd_c_image_quality, "中");
combobox_add_item(hwnd_c_image_quality, "低");

3. 设置当前选择的index
SendMessage(hwnd_c_image_quality, CB_SETCURSEL, 1, 0); 

4. 获取选择的index
LRESULT  quanlity =  SendMessage(GetDlgItem(hwnd_frame, id_c_image_quality), CB_GETCURSEL, 0, 0);

创建进度条

hwnd_progressbar =  CreateWindowEx(0, "msctls_progress32", "",
                                       WS_CHILD | WS_VISIBLE , // | WS_DISABLED
                                       12, // xpos
                                       451, // ypos
                                       549, //width
                                       21, //height
                                       hwnd_frame, (HMENU)id_progressbar, g_hInstance,  NULL) ;

1. 初始化进度条的最小值和最大值
SendMessage(hwnd_progressbar, PBM_SETRANGE, 0, MAKELPARAM(0, 100)); 

2. 更新进度
SendMessage(hwnd_progressbar, PBM_SETPOS, 80, 0L);

3. 重置进度条位置为0
SendMessage(hwnd_progressbar, PBM_SETPOS, 0, 0L);

创建一个WS_EX_TOOLWINDOW样式的窗口

hwnd_log_frame = CreateWindowEx(
                         WS_EX_TOOLWINDOW,                   /* Extended possibilites for variation */  
                         "CodeBlocksWindowsApp",         /* Classname */
                         "日志",       /* Title Text */
                         WS_SYSMENU | WS_SIZEBOX, /* default window */
                         CW_USEDEFAULT,       /* Windows decides the position */
                         CW_USEDEFAULT,       /* where the window ends up on the screen */
                         460,                 /* The programs width */
                         168,                 /* and height in pixels */
                         hwnd_parent,        /* The window is a child-window to desktop */
                         NULL,                /* No menu */
                         hThisInstance,       /* Program Instance handler */
                         NULL                 /* No Window Creation data */
                     );

WS_EX_TOOLWINDOW，带有这个属性的窗口有以下特点：
1. 不在任务栏显示。
2. 不显示在Alt+Tab的切换列表中。
3. 在任务管理器的窗口管理Tab中不显示。
4. 标题栏没有图标，标题栏的高度很小，很特珠的一个窗口

创建一个无边框的窗口

hwnd_ad_window = CreateWindowEx(
                         0,                   /* Extended possibilites for variation */
                         "CodeBlocksWindowsApp",         /* Classname */
                         "ad_window",       /* Title Text */
                         WS_CLIPCHILDREN | WS_CLIPSIBLINGS | WS_POPUP, /* default window */
                         CW_USEDEFAULT,       /* Windows decides the position */
                         CW_USEDEFAULT,       /* where the window ends up on the screen */
                         400,                 /* The programs width */
                         16,                 /* and height in pixels */
                         hwnd_parent,        /* The window is a child-window to desktop */
                         NULL,                /* No menu */
                         hThisInstance,       /* Program Instance handler */
                         NULL                 /* No Window Creation data */
                     );
