我正在使用Gtk3和Python编写一个应用程序。我有一个揭示器作为侧边栏来选择内容和webkit webview来显示主要内容。当显示器被隐藏时,webview没有填满整个窗口空间,我不知道为什么。如有任何帮助,不胜感激。
from gi.repository import Gtk, Gio
from gi.repository import WebKit
HEIGHT = 500
WIDTH = 800
class MainWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="Resolution")
self.set_border_width(0)
self.set_default_size(WIDTH, HEIGHT)
hb = Gtk.HeaderBar()
hb.props.show_close_button = True
hb.props.title = "Resolution"
self.set_titlebar(hb)
button = Gtk.Button()
icon = Gio.ThemedIcon(name="emblem-system-symbolic")
image = Gtk.Image.new_from_gicon(icon, 1)
button.add(image)
button.connect("clicked", self.sidebarShowHide)
button.set_focus_on_click(False)
hb.pack_start(button)
sidebarbox = Gtk.Box(orientation=Gtk.Orientation.VERTICAL, spacing=0)
toplevelbox = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL, spacing=0)
self.add(toplevelbox)
self.sidebar = Gtk.Revealer()
self.sidebar.set_transition_duration(0)
self.sidebar.set_reveal_child(False)
toplevelbox.pack_start(self.sidebar, False, False, 0)
self.sidebar.add(sidebarbox)
self.searchentry = Gtk.SearchEntry()
self.searchentry.connect("search-changed", self.search_changed)
sidebarbox.pack_start(self.searchentry, False, False, 0)
label = Gtk.Label("Contents Selector")
sidebarbox.pack_start(label, True, True, 0)
scroller = Gtk.ScrolledWindow()
content = WebKit.WebView()
scroller.add(content)
toplevelbox.pack_start(scroller, True, True, 0)
content.open("/home/oliver/resolution/placeholder.html")
def sidebarShowHide(self, button):
if self.sidebar.get_reveal_child():
self.sidebar.set_reveal_child(False)
else:
self.sidebar.set_reveal_child(True)
def search_changed(self, searchentry):
pass
win = MainWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
好吧,我几个月前做了一些GtkRevealer,它工作。看到这段代码不是这样,我简直要发疯了。
我再次打开我的项目,看看那部分在哪里,它变成了Gtk的顶层容器。启示器驻留,必须有Gtk.Orientation.VERTICAL..如果你改变你的" topplevelbox "的方向,它会工作,但它不会是侧边栏。它会从上到下。如果您将GtkBox更改为GtkGrid,则情况相同。如果我猜它取决于子元素的默认方向。
的解决办法,是使用小部件隐藏/显示机制(相信我,我洗劫你的代码,它的工作)。
from gi.repository import Gtk, Gio
from gi.repository import WebKit
HEIGHT = 500
WIDTH = 800
class MainWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="Resolution")
self.set_border_width(0)
self.set_default_size(WIDTH, HEIGHT)
hb = Gtk.HeaderBar()
hb.props.show_close_button = True
hb.props.title = "Resolution"
self.set_titlebar(hb)
button = Gtk.Button()
icon = Gio.ThemedIcon(name="emblem-system-symbolic")
image = Gtk.Image.new_from_gicon(icon, 1)
button.add(image)
button.connect("clicked", self.sidebarShowHide)
button.set_focus_on_click(False)
hb.pack_start(button)
sidebarbox = Gtk.Box(orientation=Gtk.Orientation.VERTICAL, spacing=0)
toplevelbox = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL, spacing=0)
self.add(toplevelbox)
self.sidebar = Gtk.Box()
toplevelbox.pack_start(self.sidebar, False, False, 0)
self.sidebar.add(sidebarbox)
self.searchentry = Gtk.SearchEntry()
self.searchentry.connect("search-changed", self.search_changed)
sidebarbox.pack_start(self.searchentry, False, False, 0)
label = Gtk.Label("Contents Selector")
sidebarbox.pack_start(label, True, True, 0)
scroller = Gtk.ScrolledWindow()
content = WebKit.WebView()
scroller.add(content)
toplevelbox.pack_start(scroller, True, True, 0)
content.open("/home/oliver/resolution/placeholder.html")
def sidebarShowHide(self, button):
if self.sidebar.get_visible():
self.sidebar.hide ()
else:
self.sidebar.show ()
def search_changed(self, searchentry):
pass
win = MainWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
闻起来像有bug。
作为一种变通方法,您可以使用def sidebarShowHide(self, button):
self.sidebarbox.set_visible(not self.sidebarbox.get_visible())
,但这不会产生任何过渡动画,但会删除其分配的空间,暂时不可见。
实际上,git仓库中提供的C演示会按预期调整大小,所以这实际上可能需要对子部件的首选方向做一些事情。
