既知のWindowsメッセージID(WM_MSG)に対してユーザー定義関数を登録します。
GUIRegisterMsg ( msgID, "function" )
パラメータ
msgID | WindowsメッセージID (付録を参照:Windowsメッセージコード). |
function | メッセージに対応して呼び出されるユーザー関数の名前、またはメッセージ登録を削除するための空文字列 ""。 |
返し値
成功 | 1 |
失敗 | 0 |
注意
!!! ユーザー関数を正常に動作させるためには最大で4つの関数パラメータを定義しなければいけません。 パラメータの定義が不適切な場合、関数は呼び出されません !!!位置 | パラメータ | 意味 |
1 | hWnd | メッセージを投げたGUIのウィンドウハンドル。 |
2 | Msg | WindowsメッセージID。 |
3 | wParam | 最初のメッセージパラメータ(16進数値)。 |
4 | lParam | 2番目のメッセージパラメータ(16進数値)。 |
