爲什麼有錯誤？

mainwindow.obj：-1：BLAD：LNK2019：在函數解析的外部符號__imp_GetForegroundWindow引用「私人：無效__cdecl的MainWindow ::重複（無效）」（重複@主窗口@@ AEAAXXZ？）

和

mainwindow.obj：-1：BLAD：LNK2019：解析外部符號__imp_PostMessageW在函數引用「私人：無效__cdecl的MainWindow ::重複（無效）」（？重複@主窗口@@ AEAAXXZ）

怎麼辦這個權利？我想在虛空中重複點擊鼠標在屏幕上（甚至外部應用程序）。這個怎麼做？

請儘量減少這一點，擺脫'.h'文件和'.ui'文件 - 它們不是必需的。聲明和定義可以在一個文件中。您可以將小部件和佈局直接添加到「MainWindow」類。 –

這是否應該只在您的Qt應用程序或其他應用程序中單擊？ –

在所有的應用程序，不僅在我的應用程序 –

（發佈解決方案代表OP）。

它現在有效。謝謝。我用：

LIBS += -luser32

在我的項目文件

和：

mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0); 
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);

在我的代碼。
