我想实现一个带有 2 个字段的状态栏。第一个左对齐,第二个右对齐。我想要的插图:
| | | | ================================================== ================================ | 一些状态文本。v. 1.0.32 |
我目前的代码:
self.CreateStatusBar(2)
self.SetStatusWidths([-1, -1])

但是右边的字段是左对齐的,所以看起来像这样:
| | | | ================================================== ================================ | 一些状态文本。v. 1.0.32 |
有什么方法可以使正确字段中的文本向右对齐吗?
好的,我已经解决了这个问题(尽管感觉像是黑客攻击。)我创建了一个定义两个字段的自定义工具栏。左字段可以像平常一样控制,右字段包含一个StaticText控件,其中包含手动定位的版本号。用于定位文本的代码是特定于平台的,因为它在 Windows 上看起来有点不同。以下是一些屏幕截图:

下面是自定义状态栏的代码:
class CustomStatusBar(wx.StatusBar):
"""A custom status bar for displaying the application version in the bottom
right corner."""
def __init__(self, parent):
wx.StatusBar.__init__(self, parent, -1)
self.SetFieldsCount(2)
self.SetStatusWidths([-1, -1])
# Set up the version label.
self.version_label = wx.StaticText(self, -1, 'Version: ' + VERSION)
self.reposition_version_label()
# Listen to the resize event.
self.Bind(wx.EVT_SIZE, self.on_resize)
def on_resize(self, event):
self.reposition_version_label()
def reposition_version_label(self):
# Get the rect of the second field.
field_rect = self.GetFieldRect(1)
label_rect = self.version_label.GetRect()
# Reduce the width of the field rect to the width of the label rect and
# increase it's x value by the same about. This will result in it being
# right aligned.
width_diff = field_rect.width - label_rect.width
field_rect.width = label_rect.width
field_rect.x += width_diff
# On windows, the text is a little too high up, so increase the Y value
# a little.
if sys.platform == 'win32':
field_rect.y += 3
# Set the resulting rect to the label.
self.version_label.SetRect(field_rect)

此代码位于我Frame的构造函数中,用于创建和放置状态栏:
self.statusbar = CustomStatusBar(self)
self.SetStatusBar(self.statusbar)

我将此功能添加到我的框架中,以便轻松更新状态:
def set_status_text(text):
self.statusbar.SetStatusText(text, 0)

我希望这对其他人有帮助。
这个 hacky 版本并不完全符合我的要求。我发现根据字符串的像素大小设置静态宽度大小对我来说非常有用。能很好地适应环境并可以动态改变。这是使用 Python 3 和 wxPython Phoenix 完成的,所以也许这个方法以前不可用。
这是一个简单的版本。
import wx
class MainWindow(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent)
version = "v. 1.0.32 (2012-11-03)"
# Returns a Size object of the pixel dimensions of a string
version_size = wx.Window.GetTextExtent(self, version)
# Create a status bar with two sections
self.CreateStatusBar(2)
# Set the left side to a negative number indicating it's fluid width
# The right side will be the exact size of the version string
self.SetStatusWidths([-1, version_size.width])
# Set the left side of the status bar to some text. 0 is first section
self.SetStatusText("left status bar text", 0)
# Set right side to version number. 1 is second section
self.SetStatusText(version, 1)
self.Show()
app = wx.App()
frame = MainWindow(None)
app.MainLoop()

为了展示如何动态更新它,这里是一个带有线程随机更新的更复杂的版本。
import wx
import time
import random
import threading
class MainWindow(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent)
