WM_SYSKEYDOWN top-level constant Null safety

int const WM_SYSKEYDOWN

Posted to the window with the keyboard focus when the user presses the F10 key (which activates the menu bar) or holds down the ALT key and then presses another key. It also occurs when no window currently has the keyboard focus; in this case, the WM_SYSKEYDOWN message is sent to the active window. The window that receives the message can distinguish between these two contexts by checking the context code in the lParam parameter.

Implementation

const WM_SYSKEYDOWN = 0x0104;
