宽度

Question

在PyGTK中，什么是计算小部件尺寸的最简单方法？我知道这是很容易做到的gtk.窗口对象，但我在参考手册中找不到任何方法来获取其他对象的尺寸。你知道吗

非常感谢您的帮助

您可能正在寻找get_allocation方法：

The get_allocation() method returns a gtk.gdk.Rectangle containing the bounds of the widget's allocation.

或size_request：

The size_request() method returns the preferred size of a widget as a tuple containing its required width and height. This method is typically used when implementing a gtk.Container subclass to arrange the container's child widgets and decide what size allocations to give them with the size_allocate() method. Obtaining a size request requires that the widget be associated with a screen, because font information may be needed.

Also remember that the size request is not necessarily the size a widget will actually be allocated.

后者是小部件希望拥有的大小（给定字体信息），前者是在布局小部件时由其容器实际给定的大小。你知道吗
