如何创建一个以 HWND 为父级的 QWidget？

Question

With wxWidgets I use the following code:

HWND main_window = ...
...
wxWindow *w = new wxWindow();
wxWindow *window = w->CreateWindowFromHWND(0, (WXHWND) main_window);

How do I do the same thing in Qt? The HWND is the handle of the window I want as the parent window for the new QtWidget.

Answer 1

Use the create method of QWidget.

HWND main_window = ...
...
QWidget *w = new QWidget();
w->create((WinId)main_window);

Answer 2

您是否尝试过Qt / MFC迁移框架中的QWinWidget类？

Answer 3

How about fromWinId https://doc-snapshots.qt.io/qt6-dev/qwindow.html#fromWinId

Creates a local representation of a window created by another process or by using native libraries below Qt.
