我正在尝试使用glade进行可持续模态对话。 为此，我使用“toplevels”中的“对话框”，正确设置transient_for_window和模态变量。然后我将小部件放到table中，所有打包到dialog-vbox中。 这正常，正如预期的那样。
但是，当我需要更复杂的GUI时，就像我现在需要的那样，并打包到dialog-vbox scrolledwindow＆gt;视＆GT; aspectframe＆GT;表＆gt;然后将小部件放在表格中，此对话框不再是模态的！经过一段时间的演奏后，我得出结论，很明显，模态问题始于滚动窗口。
是否允许在对话框中放置如此复杂的GUI？如果是 - 为什么我的对话框失去了gtkscrollwindow的模态，如果没有，人们如何做这样的任务？在我的情况下，我正在尝试进行模态对话，可以连接到不同的项目（比如可重复使用）。
