在xmal.cs文件中实现,或者重写OnPreviewKeyDown()方法:
string codeValue = ""; int InputCount = 0; protected override void OnPreviewKeyDown(KeyEventArgs e) { int keyValue = Convert.ToInt32(e.Key); if (keyValue == 156) keyValue = Convert.ToInt32(e.SystemKey); if (e.Key == Key.Up) { e.Handled = true; ScrollToVerticalOffset("up"); } if (e.Key == Key.Down) { e.Handled = true; ScrollToVerticalOffset("down"); }
//获取组合键,如Shift+F1【操作:按下Shift,同时按下F1】
if (e.KeyStates == Keyboard.GetKeyStates(Key.F1) && Keyboard.Modifiers == ModifierKeys.Shift)
{
codeValue = "Shift+F1";
}
//获取数字组合键,如200,201等【操作:依次按2 0 0 】 if (e.Key.ToString().Contains("NumPad") || (keyValue >= 34 && keyValue <= 43)) { string keyCode = e.Key.ToString().Substring(e.Key.ToString().Length - 1, 1); if (int.TryParse(keyCode, out int tmp))//如果转换失败(为false)时输出括号内容 { codeValue += keyCode; InputCount += 1; } else { codeValue = ""; InputCount = 0; } if (Core.Definition.QuickKeyManager.Instance.Exec(this.GetType(), 0, codeValue)) { e.Handled = true; codeValue = ""; InputCount = 0; } if (InputCount == 3) { codeValue = ""; InputCount = 0; } return; } if (Core.Definition.QuickKeyManager.Instance.Exec(this.GetType(), keyValue)) e.Handled = true; codeValue = ""; InputCount = 0; base.OnPreviewKeyDown(e);
}
