Question

我试图将wx.grid.Grid集中在wxPython中。我已经尝试了ID参数1,0，-1的所有可能组合。我试图将wx.ALIGN_CENTER_HORIZONTAL添加到许多sizer中。我已经在这几天工作，任何帮助将不胜感激。

我的问题是：＆＃34;我如何集中我的wxgrid？＆＃34;

这是我的代码：

main.py

import wx
from LogView import LogView

class MyFrame(wx.Frame):
    """ We simply derive a new class of Frame. """
    def __init__(self, parent, ID, title):
        wx.Frame.__init__(self, parent, ID, title=title, size=(850,725))

        self.main = wx.Panel(self)

        self.nb = wx.Notebook(self.main, 1)
        self.logView = LogView(parent=self.nb, ID=-1)
        self.mainSizer = wx.BoxSizer(wx.VERTICAL)

        self.nb.AddPage(self.logView, "Log")

        # Create sizers
        self.mainSizer = wx.BoxSizer(wx.VERTICAL)

        # Adding Objects to mainSizer
        self.mainSizer.AddSpacer(10)
        self.mainSizer.Add(self.nb, 1, wx.ALL|wx.EXPAND)

        # Set main sizer
        self.main.SetAutoLayout(True)
        self.main.SetSizer(self.mainSizer)
        self.mainSizer.Fit(self.main)
        self.Layout()
        self.Centre(wx.BOTH)
        self.Show()

app = wx.App(False)
frame = MyFrame(None, -1, 'TFM UI')
app.MainLoop()

LogView.py

import wx
from GridTable import GridTable
class LogView(wx.Panel):
    def __init__(self, parent, ID):
        wx.Panel.__init__(self, parent, ID)
        self.sizer = wx.BoxSizer(wx.VERTICAL)

        self.gridPnl = wx.Panel(self)
        self.gridPnlSizer = wx.BoxSizer(wx.VERTICAL)

        self.grid = GridTable(self.gridPnl)

        self.gridPnlSizer.AddStretchSpacer()
        self.gridPnlSizer.Add(self.grid,-1,wx.EXPAND|wx.ALIGN_CENTER_HORIZONTAL)
        self.gridPnlSizer.AddStretchSpacer()

        self.gridPnl.SetAutoLayout(True)
        self.gridPnl.SetSizer(self.gridPnlSizer)
        self.gridPnlSizer.Fit(self.gridPnl)

        self.sizer.AddSpacer(25)
        self.sizer.Add(self.gridPnl,-1,wx.EXPAND)


        self.SetAutoLayout(True)
        self.SetSizer(self.sizer)
        self.sizer.Fit(self)

GridTable.py

import wx
import wx.grid

class GridTable(wx.grid.Grid):
    def __init__(self, parent):
        #colDisplay should be a list

        wx.grid.Grid.__init__(self, parent)
        self.CreateGrid(100,3)
        for i in xrange(3):
            if i==0:
                self.SetColLabelValue(i, "Col"+str(i))
                self.SetColSize(i,85)
            else:
                self.SetColLabelValue(i, "Col"+str(i))
                self.SetColSize(i,150)

Answer 1

从LogView.py看这一行：

self.gridPnlSizer.Add(self.grid,-1,wx.EXPAND|wx.ALIGN_CENTER_HORIZONTAL)

首先，你认为using a proportion of -1，我认为这是未定义的。它导致Python在我的机器上崩溃，所以......那不是很好。默认值为0.

其次，您告诉sizer扩展小部件。我想如果小部件占用了所有可用空间，它肯定以一个定义为中心，但我不认为这就是你的意思。

最后，拉伸垫片是不必要的。所以用：

替换三行的块

self.gridPnlSizer.Add(self.grid,flag=wx.ALIGN_CENTER_HORIZONTAL)

当我这样做时，我最终得到：
