Question

我已经使用“其他项目”->“ Qt自定义设计器小部件”向导创建了一个自定义设计器小部件。

我一直在玩它，而且似乎无法弄清楚如何向我的定制设计器小部件中添加子小部件属性。这可能吗？

我添加了一个“ QTableWidget”和两个按钮。然后，我编译了小部件并将DLL移到我的Qt环境中。它已正确加载，并且在添加自定义窗口小部件时可以看到表格窗口小部件和按钮。但是，我无法更改“ QTableWidget”和两个“ QPushButton”的属性。理想情况下，我可以上推这些属性，以便设计人员在添加自定义窗口小部件时可以访问它们。那是我迷路的地方，我在网上找不到任何东西（也许我在搜索时使用了错误的单词...）。

如何在QT中将子窗口小部件属性添加到“自定义设计器窗口小部件”？
