GtkLabel在水平框中垂直展开

标签: gtk alignment gtk3

我正在尝试使用水平框将带有标签的条目小部件放在一行中。但是,标签会垂直扩展。它采用窗口的初始高度,并且不允许在其下方缩小。我尝试了填充,扩展,对齐等所有可能的组合,但是并没有改变。

如何解决?

Expanded label

#!/usr/bin/env python3

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, Gdk

class MyWindow(Gtk.Window):

    def __init__(self):
        super(MyWindow, self).__init__()

        self.init_ui()

    def init_ui(self):    


        hbox = Gtk.Box(Gtk.Orientation.HORIZONTAL, 6)
        hbox.set_homogeneous(True)
        hbox.set_baseline_position(Gtk.BaselinePosition.CENTER)

        entry = Gtk.Entry()
        entry.modify_bg(Gtk.StateType.NORMAL, Gdk.Color(6400, 6400, 6440))
        entry.connect("key-release-event", self.on_key_release)

        hbox.pack_start(entry, False, False, 10)

        self.label = Gtk.Label("Hello")
        self.label.set_width_chars(15)
        self.label.modify_bg(Gtk.StateType.NORMAL, Gdk.Color(40000, 40000, 40000))
        hbox.pack_start(self.label, False, False, 10)

        self.add(hbox)

        self.set_title("Entry")
        self.set_size_request(350, 250)

        self.connect("destroy", Gtk.main_quit)
        self.show_all()

    def on_key_release(self, widget, event):
        self.label.set_text(widget.get_text())


win = MyWindow()
Gtk.main()

在水平框之前添加另一个垂直框:

#!/usr/bin/env python3

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, Gdk

class MyWindow(Gtk.Window):

    def __init__(self):
        super(MyWindow, self).__init__()

        self.init_ui()

    def init_ui(self):    



        hbox = Gtk.Box(orientation = Gtk.Orientation.HORIZONTAL, spacing = 6)
        hbox.set_homogeneous(True)
        hbox.set_baseline_position(Gtk.BaselinePosition.CENTER)

        entry = Gtk.Entry()
        entry.modify_bg(Gtk.StateType.NORMAL, Gdk.Color(6400, 6400, 6440))
        entry.connect("key-release-event", self.on_key_release)

        hbox.pack_start(entry, False, False, 10)

        self.label = Gtk.Label("Hello")
        self.label.set_width_chars(15)
        self.label.modify_bg(Gtk.StateType.NORMAL, Gdk.Color(40000, 40000, 40000))
        hbox.pack_start(self.label, False, False, 10)

        vbox = Gtk.Box(orientation = Gtk.Orientation.VERTICAL)
        vbox.pack_start(hbox, False, False, 0)
        self.add(vbox)

        self.set_title("Entry")
        self.set_size_request(350, 250)

        self.connect("destroy", Gtk.main_quit)
        self.show_all()

    def on_key_release(self, widget, event):
        self.label.set_text(widget.get_text())


win = MyWindow()
Gtk.main()

请注意,在Python3和Gtk中使用非关键字参数并不总是能正常工作,请使用hbox = Gtk.Box(Gtk.Orientation.HORIZONTAL, 6)代替hbox = Gtk.Box(orientation = Gtk.Orientation.HORIZONTAL, spacing = 6)
