gtk：展开小部件，就好像它里面有一些文本一样
我有一个 GTK 小部件，在本例中是一个 TreeView。它一开始非常小并且被压缩，因为除了列名称之外没有任何文本。当我添加内容时，它会水平增长以覆盖文本，并垂直增长以覆盖额外的行。如果我把它们拿走，它会保持其扩大的尺寸。
当您添加内容时，窗口总是会调整大小，这有点烦人。我的问题是 - 如何“预先”调整小部件的大小？就像一种方法是用垃圾文本填充它，我认为这是它可以获得的最大尺寸，然后删除文本，但这看起来不太漂亮。有更好的办法吗？
I have a GTK widget, in this case, a TreeView. It starts off pretty small and compressed, as there's no text in it besides the columns names. As I add things, it grows horizontally to cover the text and vertically to cover the extra rows. If I then take those away, it retains its expanded size.
It's kind of annoying for your window to always be resizing as you add things. My question is - how can I "pre-"size the widget? Like one way would be to fill it with junk text that I think is the biggest size it can get, and then remove the text, but that won't look very pretty. Is there a better way?

treeview.set_size_request(width, height)（但是之后你的树视图在需要时不会增长。）expand=True和fill=True打包它？window.set_default_size(width, height)对整个gtk.Window来说是最好的解决方案，因为正如您所说，“预先”调整了窗口的大小。它仍然可以增长，或者由用户调整得更小。treeview.set_size_request(width, height)(but then your tree view won't grow when it needs to afterwards.)expand=Trueandfill=True?window.set_default_size(width, height)on your wholegtk.Windowis the best solution, because that "pre-"sizes the window as you say. It can still grow, or be resized smaller by the user.
