Variables | |
| constexpr xtd::uint32 | WM_NULL |
| Performs no operation. An application sends the WM_NULL message if it wants to post a message that the recipient window will ignore. | |
| constexpr xtd::uint32 | WM_CREATE |
| Sent when an application requests that a window be created by calling the CreateWindowEx or CreateWindow function. (The message is sent before the function returns.) The window procedure of the new window receives this message after the window is created, but before the window becomes visible. | |
| constexpr xtd::uint32 | WM_DESTROY |
| Sent when a window is being destroyed. It is sent to the window procedure of the window being destroyed after the window is removed from the screen. | |
| constexpr xtd::uint32 | WM_MOVE |
| Sent after a window has been moved. | |
| constexpr xtd::uint32 | WM_SIZE |
| Sent to a window after its size has changed. | |
| constexpr xtd::uint32 | WM_ACTIVATE |
| Sent to both the window being activated and the window being deactivated. If the windows use the same input queue, the message is sent synchronously, first to the window procedure of the top-level window being deactivated, then to the window procedure of the top-level window being activated. If the windows use different input queues, the message is sent asynchronously, so the window is activated immediately. | |
| constexpr xtd::uint32 | WM_SETFOCUS |
| Sent to a window after it has gained the keyboard focus. | |
| constexpr xtd::uint32 | WM_KILLFOCUS |
| Sent to a window immediately before it loses the keyboard focus. | |
| constexpr xtd::uint32 | WM_ENABLE |
| Sent when an application changes the enabled state of a window. It is sent to the window whose enabled state is changing. This message is sent before the EnableWindow function returns, but after the enabled state (WS_DISABLED style bit) of the window has changed. | |
| constexpr xtd::uint32 | WM_SETREDRAW |
| An application sends the WM_SETREDRAW message to a window to allow changes in that window to be redrawn or to prevent changes in that window from being redrawn. | |
| constexpr xtd::uint32 | WM_SETTEXT |
| Sets the text of a window. | |
| constexpr xtd::uint32 | WM_GETTEXT |
| Copies the text that corresponds to a window into a buffer provided by the caller. | |
| constexpr xtd::uint32 | WM_GETTEXTLENGTH |
| Determines the length, in characters, of the text associated with a window. | |
| constexpr xtd::uint32 | WM_PAINT |
| The WM_PAINT message is sent when the system or another application makes a request to paint a portion of an application's window. The message is sent when the UpdateWindow or RedrawWindow function is called, or by the DispatchMessage function when the application obtains a WM_PAINT message by using the GetMessage or PeekMessage function. | |
| constexpr xtd::uint32 | WM_CLOSE |
| Sent as a signal that a window or an application should terminate. | |
| constexpr xtd::uint32 | WM_QUERYENDSESSION |
| The WM_QUERYENDSESSION message is sent when the user chooses to end the session or when an application calls one of the system shutdown functions. If any application returns zero, the session is not ended. The system stops sending WM_QUERYENDSESSION messages as soon as one application returns zero. | |
| constexpr xtd::uint32 | WM_QUIT |
| Indicates a request to terminate an application, and is generated when the application calls the PostQuitMessage function. This message causes the GetMessage function to return zero. | |
