問題描述
在我的 Qt 應用程序中，我在默認瀏覽器中打開了一個 URL.之后我想再次將我的應用程序的主窗口放在最前面.
In my Qt-application I open a URL in the default-browser. Afterwards I want to bring the main-window of my application to the front again.
我嘗試了我能找到的所有方法，但都沒有奏效.它所做的只是在任務欄(Window 7)中閃爍舉個例子:
I tried all approaches I could find but none worked. All it does is blink in the taskbar (of Window 7) Here’s an example:
this->viewer->show();
this->viewer->raise();
this->viewer->activateWindow();
*viewer 是一個指向從 QDeclarativeView 派生的 QmlApplicationViewer 的指針
*viewer is a pointer to a QmlApplicationViewer which is derived from QDeclarativeView
推薦答案
此問題特定于 Windows.如果活動窗口屬于某個進程，則 Windows 不允許其他進程更改活動窗口.
This problem is specific to Windows. If the active window belongs to some process, then Windows does not allow other processes to change the active Window.
