请帮助我确定Shift键是否按下.

Please help me to determine whether shift key is down.

推荐答案

要测试虚拟键的状态，您可以使用 GetAsyncKeyState() [

To test the status of a virtual-key you could use the GetAsyncKeyState()[^] function: it tell you if the required key is currently pressed or not, and if it has been pressed since the last time the function was called.

SHORT shift_status = GetAsyncKeyState(VK_SHIFT);
if (shift_status & 0x8000)
{
   // The shift key is currently pressed
}
else if (shift_status & 0x0001)
{
   // The shift key has been pressed since the last call to GetAsyncKeyState()
   // NOTE: you cannot rely on this information! See the remarks
   // section on the GetAsyncKeyState() documentation
}

如果要区分左移键和右移键，请使用VK_LSHIFT和/或VK_RSHIFT而不是VK_SHIFT.

If you want to distinguish between the left and right shift keys, use VK_LSHIFT and/or VK_RSHIFT instead than VK_SHIFT.

您好，当您按下某个键时，可以使用
GetAsyncKeyState();

代码


如果(GetAsyncKeyState(VK_SHIFT)& 0x8000)
{
//按键当前处于按下状态
}

hello, when you press a key you can use the
GetAsyncKeyState();

Code


if (GetAsyncKeyState(VK_SHIFT) & 0x8000)
{
// The key is currently down
}
