Question

如果通过wxpython创建框架并更改staticText的内容，则将初始化对齐。我怎么解决这个问题？我想再次对齐它。

Answer 1

要动态设置窗口对齐标记

获取wx.Sizer
找到wx.SizerItem
通过SetFlag
致电Sizer.Layout()

这是一个简单的例子：

import wx
import traceback


def run():
    app = wx.App()
    # create the test frame
    frame = wx.Frame(None, title="test frame", size=(500, 500))

    # create a simple boxsizer
    sizer = wx.BoxSizer()
    # create the object that we'll be dynamically adjusting
    st = wx.StaticText(frame, label="Click me")
    st.SetFont(wx.Font(30, 74, 90, wx.FONTWEIGHT_BOLD, True, "Arial Rounded"))
    # align the text to the middle initially
    sizer.Add(st, 0, wx.ALIGN_CENTER_VERTICAL)
    frame.SetSizer(sizer)

    # bind to an arbitrary event
    st.Bind(wx.EVT_LEFT_DOWN, on_click)
    # do the initial layout and show the frame
    frame.Layout()
    frame.Show()
    app.MainLoop()


def on_click(event):
    event.Skip()
    # retrieving the static text object
    st = event.GetEventObject()  # type: wx.StaticText
    # get the sizer that contains this object
    sizer = st.GetContainingSizer()  # type: wx.BoxSizer
    # find the sizer item
    # the sizer item holds the alignment information and tells
    # the sizer how to display this object
    sizer_item = sizer.GetItem(st)  # type: wx.SizerItem
    # alternate between aligning at the top & bottom
    if sizer_item.GetFlag() & wx.ALIGN_BOTTOM:
        print("Setting alignment to top")
        sizer_item.SetFlag(wx.ALIGN_TOP)
    else:
        print("Setting alignment to bottom")
        sizer_item.SetFlag(wx.ALIGN_BOTTOM)
    # call Layout to recalculate the object positions
    sizer.Layout()


if __name__ == "__main__":
    try:
        run()
    except:
        traceback.print_exc()
        input()

这个问题是由文本控件的自动调整引起的，所以为了防止只是将wx.ST_NO_AUTORESIZE添加到样式中它就会被解决。

txtCtrl = wx.StaticText(parent, -1, "some label", style = wx.ALIGN_CENTER| wx.ST_NO_AUTORESIZE)

静态文本没有名为SetStyle（）

的方法
