如何将状态栏中的文本与wxPython中的右侧对齐?

我想要一个包含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:

|                                                                               |
|                                                                               |
=================================================================================
| Some status text.                                                   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:

|                                                                               |
|                                                                               |
=================================================================================
| Some status text.                      v. 1.0.32                              |

有没有办法让正确的字段中的文字与右边对齐?

好的,我已经解决了这个问题(尽管感觉就像是黑客。)我创建了一个定义两个字段的自定义工具栏。左侧字段可以像平常一样进行控制,右侧字段包含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,因为它在窗口上看起来有点不同。以下是一些截图:

Windows 7:

OSX 10.8.1 Mountain Lion:

以下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)

此代码位于我的Frame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于状态更新:

def set_status_text(text):
    self.statusbar.SetStatusText(text, 0)

我希望这可以帮助其他人。

您可以尝试使用制表符:

self.SetStatusText(0,"\tCentered")
self.SetStatusText(1,"\t\tRight Aligned")

这适用于Windows,但我不确定它是否在其他wxWidgets发行版中实现。您需要使用style=0创建wx.StatusBar以禁用右下角的抓握。文本对齐不会考虑到夹点,它会被切断。如果这不起作用,您可以通过将右侧面板设置为静态大小来模拟正确的文本对齐:

self.SetStatusWidths([-1, 100])

但其上的文字将保持左对齐。要使文本看起来正确对齐,您必须用空格填充文本。请记住,不同的系统和用户可能使用不同的字体,因此间距可能不准确。

附录:将文本与\t对齐实际上是本机Windows状态栏控件的一项功能。为了使其能够在其他操作系统上运行,它们的本机控件或wxWidgets都必须实现该行为。

hacky版本并不适合我想要的东西。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很有用。很好地适应环境,可以动态更改。这是用Python 3和wxPython Phoenix完成的,所以也许以前这个方法不可用。

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)

        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 section
        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()

        # Thread to update status bar with causing the GUI to hang
        run_version_updates = threading.Thread(target=self.thread_version_updating)
        run_version_updates.start()

    def thread_version_updating(self):
        for i in range(10):
            time.sleep(1)
            # Create a random string of 1-20 characters containing only "ABC123"
            random_string = "".join(random.choice("ABC123") for _ in range(random.randrange(1,20)))
            self.update_version(random_string)

    def update_version(self, version):
        # Get width of string, set status bar width, then update the text
        size = wx.Window.GetTextExtent(self, version)
        self.SetStatusWidths([-1, size.width])
        self.SetStatusText(version, 1)

app = wx.App()
frame = MainWindow(None)
app.MainLoop()

我只有一个操作系统,但这里有不同的Windows 7主题。
