CreateWindow function
Creates an overlapped, pop-up, or child window. It specifies the window class, window title, window style, and (optionally) the initial position and size of the window. The function also specifies the window's parent or owner, if any, and the window's menu.
To use extended window styles in addition to the styles supported by CreateWindow, use the CreateWindowEx function.
Syntax
HWND WINAPI CreateWindow(_In_opt_ LPCTSTR lpClassName,_In_opt_ LPCTSTR lpWindowName,_In_ DWORD dwStyle,_In_ int x,_In_ int y,_In_ int nWidth,_In_ int nHeight,_In_opt_ HWND hWndParent,_In_opt_ HMENU hMenu,_In_opt_ HINSTANCE hInstance,_In_opt_ LPVOID lpParam
);
Parameters
- lpClassName [in, optional]
-
Type: LPCTSTR
A null-terminated string or a class atom created by a previous call to the RegisterClass or RegisterClassEx function. The atom must be in the low-order word of lpClassName; the high-order word must be zero. If lpClassName is a string, it specifies the window class name. The class name can be any name registered with RegisterClass or RegisterClassEx, provided that the module that registers the class is also the module that creates the window. The class name can also be any of the predefined system class names. For a list of system class names, see the Remarks section.
- lpWindowName [in, optional]
-
Type: LPCTSTR
The window name. If the window style specifies a title bar, the window title pointed to by lpWindowName is displayed in the title bar. When using CreateWindow to create controls, such as buttons, check boxes, and static controls, use lpWindowName to specify the text of the control. When creating a static control with the SS_ICON style, use lpWindowName to specify the icon name or identifier. To specify an identifier, use the syntax "#num".
- dwStyle [in]
-
Type: DWORD
The style of the window being created. This parameter can be a combination of the window style values, plus the control styles indicated in the Remarks section.
- x [in]
-
Type: int
The initial horizontal position of the window. For an overlapped or pop-up window, the x parameter is the initial x-coordinate of the window's upper-left corner, in screen coordinates. For a child window, x is the x-coordinate of the upper-left corner of the window relative to the upper-left corner of the parent window's client area. If this parameter is set to CW_USEDEFAULT, the system selects the default position for the window's upper-left corner and ignores the y parameter. CW_USEDEFAULT is valid only for overlapped windows; if it is specified for a pop-up or child window, the x and y parameters are set to zero.
- y [in]
-
Type: int
The initial vertical position of the window. For an overlapped or pop-up window, the y parameter is the initial y-coordinate of the window's upper-left corner, in screen coordinates. For a child window, y is the initial y-coordinate of the upper-left corner of the child window relative to the upper-left corner of the parent window's client area. For a list box, y is the initial y-coordinate of the upper-left corner of the list box's client area relative to the upper-left corner of the parent window's client area.
If an overlapped window is created with the WS_VISIBLE style bit set and the x parameter is set to CW_USEDEFAULT, then the y parameter determines how the window is shown. If the y parameter is CW_USEDEFAULT, then the window manager calls ShowWindow with the SW_SHOW flag after the window has been created. If the y parameter is some other value, then the window manager calls ShowWindow with that value as the nCmdShow parameter.
- nWidth [in]
-
Type: int
The width, in device units, of the window. For overlapped windows, nWidth is either the window's width, in screen coordinates, or CW_USEDEFAULT. If nWidth is CW_USEDEFAULT, the system selects a default width and height for the window; the default width extends from the initial x-coordinate to the right edge of the screen, and the default height extends from the initial y-coordinate to the top of the icon area. CW_USEDEFAULT is valid only for overlapped windows; if CW_USEDEFAULT is specified for a pop-up or child window, nWidth and nHeight are set to zero.
- nHeight [in]
-
Type: int
The height, in device units, of the window. For overlapped windows, nHeight is the window's height, in screen coordinates. If nWidth is set to CW_USEDEFAULT, the system ignores nHeight.
- hWndParent [in, optional]
-
Type: HWND
A handle to the parent or owner window of the window being created. To create a child window or an owned window, supply a valid window handle. This parameter is optional for pop-up windows.
To create a message-only window, supply HWND_MESSAGE or a handle to an existing message-only window.
- hMenu [in, optional]
-
Type: HMENU
A handle to a menu, or specifies a child-window identifier depending on the window style. For an overlapped or pop-up window, hMenu identifies the menu to be used with the window; it can be NULL if the class menu is to be used. For a child window, hMenu specifies the child-window identifier, an integer value used by a dialog box control to notify its parent about events. The application determines the child-window identifier; it must be unique for all child windows with the same parent window.
- hInstance [in, optional]
-
Type: HINSTANCE
A handle to the instance of the module to be associated with the window.
- lpParam [in, optional]
-
Type: LPVOID
A pointer to a value to be passed to the window through the CREATESTRUCT structure (lpCreateParams member) pointed to by the lParam param of the WM_CREATE message. This message is sent to the created window by this function before it returns.
If an application calls CreateWindow to create a MDI client window, lpParam should point to a CLIENTCREATESTRUCT structure. If an MDI client window calls CreateWindow to create an MDI child window, lpParam should point to a MDICREATESTRUCT structure. lpParam may be NULL if no additional data is needed.
Return value
Type:
Type: HWND
If the function succeeds, the return value is a handle to the new window.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
This function typically fails for one of the following reasons:
- an invalid parameter value
- the system class was registered by a different module
- The WH_CBT hook is installed and returns a failure code
- if one of the controls in the dialog template is not registered, or its window window procedure fails WM_CREATE or WM_NCCREATE
Remarks
Before returning, CreateWindow sends a WM_CREATE message to the window procedure. For overlapped, pop-up, and child windows, CreateWindow sends WM_CREATE, WM_GETMINMAXINFO, and WM_NCCREATE messages to the window. The lParam parameter of the WM_CREATE message contains a pointer to a CREATESTRUCT structure. If the WS_VISIBLE style is specified, CreateWindow sends the window all the messages required to activate and show the window.
If the created window is a child window, its default position is at the bottom of the Z-order. If the created window is a top-level window, its default position is at the top of the Z-order (but beneath all topmost windows unless the created window is itself topmost).
For information on controlling whether the Taskbar displays a button for the created window, see Managing Taskbar Buttons.
For information on removing a window, see the DestroyWindow function.
The following predefined system classes can be specified in the lpClassName parameter. Note the corresponding control styles you can use in the dwStyle parameter.
System class | Meaning |
---|---|
BUTTON |
Designates a small rectangular child window that represents a button the user can click to turn it on or off. Button controls can be used alone or in groups, and they can either be labeled or appear without text. Button controls typically change appearance when the user clicks them. For more information, see Buttons For a table of the button styles you can specify in the dwStyle parameter, see Button Styles. |
COMBOBOX |
Designates a control consisting of a list box and a selection field similar to an edit control. When using this style, an application should either display the list box at all times or enable a drop-down list box. If the list box is visible, typing characters into the selection field highlights the first list box entry that matches the characters typed. Conversely, selecting an item in the list box displays the selected text in the selection field. For more information, see Combo Boxes. For a table of the combo box styles you can specify in the dwStyle parameter, see Combo Box Styles. |
EDIT |
Designates a rectangular child window into which the user can type text from the keyboard. The user selects the control and gives it the keyboard focus by clicking it or moving to it by pressing the TAB key. The user can type text when the edit control displays a flashing caret; use the mouse to move the cursor, select characters to be replaced, or position the cursor for inserting characters; or use the BACKSPACE key to delete characters. For more information, see Edit Controls. For a table of the edit control styles you can specify in the dwStyle parameter, see Edit Control Styles. |
LISTBOX |
Designates a list of character strings. Specify this control whenever an application must present a list of names, such as file names, from which the user can choose. The user can select a string by clicking it. A selected string is highlighted, and a notification message is passed to the parent window. For more information, see List Boxes. For a table of the list box styles you can specify in the dwStyle parameter, see List Box Styles. |
MDICLIENT |
Designates an MDI client window. This window receives messages that control the MDI application's child windows. The recommended style bits are WS_CLIPCHILDREN and WS_CHILD. Specify the WS_HSCROLL and WS_VSCROLL styles to create an MDI client window that allows the user to scroll MDI child windows into view. For more information, see Multiple Document Interface. |
RichEdit |
Designates a Microsoft Rich Edit 1.0 control. This window lets the user view and edit text with character and paragraph formatting, and can include embedded Component Object Model (COM) objects. For more information, see Rich Edit Controls. For a table of the rich edit control styles you can specify in the dwStyle parameter, see Rich Edit Control Styles. |
RICHEDIT_CLASS |
Designates a Microsoft Rich Edit 2.0 control. This controls let the user view and edit text with character and paragraph formatting, and can include embedded COM objects. For more information, see Rich Edit Controls. For a table of the rich edit control styles you can specify in the dwStyle parameter, see Rich Edit Control Styles. |
SCROLLBAR |
Designates a rectangle that contains a scroll box and has direction arrows at both ends. The scroll bar sends a notification message to its parent window whenever the user clicks the control. The parent window is responsible for updating the position of the scroll box, if necessary. For more information, see Scroll Bars. For a table of the scroll bar control styles you can specify in the dwStyle parameter, see Scroll Bar Control Styles. |
STATIC |
Designates a simple text field, box, or rectangle used to label, box, or separate other controls. Static controls take no input and provide no output. For more information, see Static Controls. For a table of the static control styles you can specify in the dwStyle parameter, see Static Control Styles. |
CreateWindow is implemented as a call to the CreateWindowEx function, as shown below.
#define CreateWindowA(lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)\ CreateWindowExA(0L, lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)#define CreateWindowW(lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)\ CreateWindowExW(0L, lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)#ifdef UNICODE #define CreateWindow CreateWindowW #else #define CreateWindow CreateWindowA #endif

Window Styles
The following are the window styles. After the window has been created, these styles cannot be modified, except as noted.
Constant/value | Description |
---|---|
|
The window has a thin-line border. |
|
The window has a title bar (includes the WS_BORDER style). |
|
The window is a child window. A window with this style cannot have a menu bar. This style cannot be used with the WS_POPUP style. |
|
Same as the WS_CHILD style. |
|
Excludes the area occupied by child windows when drawing occurs within the parent window. This style is used when creating the parent window. |
|
Clips child windows relative to each other; that is, when a particular child window receives a WM_PAINT message, the WS_CLIPSIBLINGS style clips all other overlapping child windows out of the region of the child window to be updated. If WS_CLIPSIBLINGS is not specified and child windows overlap, it is possible, when drawing within the client area of a child window, to draw within the client area of a neighboring child window. |
|
The window is initially disabled. A disabled window cannot receive input from the user. To change this after a window has been created, use the EnableWindow function. |
|
The window has a border of a style typically used with dialog boxes. A window with this style cannot have a title bar. |
|
The window is the first control of a group of controls. The group consists of this first control and all controls defined after it, up to the next control with the WS_GROUP style. The first control in each group usually has the WS_TABSTOP style so that the user can move from group to group. The user can subsequently change the keyboard focus from one control in the group to the next control in the group by using the direction keys. You can turn this style on and off to change dialog box navigation. To change this style after a window has been created, use the SetWindowLong function. |
|
The window has a horizontal scroll bar. |
|
The window is initially minimized. Same as the WS_MINIMIZE style. |
|
The window is initially maximized. |
|
The window has a maximize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified. |
|
The window is initially minimized. Same as the WS_ICONIC style. |
|
The window has a minimize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified. |
|
The window is an overlapped window. An overlapped window has a title bar and a border. Same as the WS_TILED style. |
|
The window is an overlapped window. Same as the WS_TILEDWINDOW style. |
|
The windows is a pop-up window. This style cannot be used with the WS_CHILD style. |
|
The window is a pop-up window. The WS_CAPTION and WS_POPUPWINDOW styles must be combined to make the window menu visible. |
|
The window has a sizing border. Same as the WS_THICKFRAME style. |
|
The window has a window menu on its title bar. The WS_CAPTION style must also be specified. |
|
The window is a control that can receive the keyboard focus when the user presses the TAB key. Pressing the TAB key changes the keyboard focus to the next control with the WS_TABSTOP style. You can turn this style on and off to change dialog box navigation. To change this style after a window has been created, use the SetWindowLong function. For user-created windows and modeless dialogs to work with tab stops, alter the message loop to call the IsDialogMessage function. |
|
The window has a sizing border. Same as the WS_SIZEBOX style. |
|
The window is an overlapped window. An overlapped window has a title bar and a border. Same as the WS_OVERLAPPED style. |
|
The window is an overlapped window. Same as the WS_OVERLAPPEDWINDOW style. |
