Question

这让我很生气。有一个简单的屏幕，但它不适合并显示所有控件。我做错了什么？

[编辑]我在Ubuntu 16.4上运行它，Python 3.5.3，wx.Python 4.0.0b2 gtk2（凤凰）[\编辑]

import wx

class MainEdit(wx.Frame):
    def __init__(self, parent=None, title="Main Edit"):
        wx.Frame.__init__(self, parent, -1, title=title)
        panel = MainPanel(self)
        self.Fit()


class MainPanel(wx.Panel):
    def __init__(self, frame):
        wx.Panel.__init__(self, frame)
        txt_size = (300, 150)
        txt_style = wx.VSCROLL|wx.HSCROLL|wx.BORDER_SIMPLE|wx.TE_MULTILINE
        self.txt_A = wx.TextCtrl(self, size=txt_size, style=txt_style)
        self.txt_B = wx.TextCtrl(self, size=txt_size, style=txt_style)
        cmd_refresh = wx.Button(self, wx.ID_REFRESH)

        main_sizer = wx.BoxSizer(wx.VERTICAL)
        main_sizer.Add(self.txt_A, flag=wx.ALL, border=10)
        main_sizer.Add(self.txt_B, flag=wx.ALL, border=10)
        main_sizer.Add(cmd_refresh, flag=wx.ALL, border=10)
        self.SetSizerAndFit(main_sizer)

if __name__ == '__main__':
    app = wx.App()
    frame = MainEdit()
    frame.Show()
    app.MainLoop()

这是我得到的效果

[\ EDIT]

[编辑2017 11 03 11:20]这是我将代码更改为Rolf建议时的输出

11:18:29: Debug: ClientToScreen cannot work when toplevel window is not shown
1 (0, 0, 20, 20)
11:18:29: Debug: ClientToScreen cannot work when toplevel window is not shown
2 (0, 0, 320, 389)
3 (0, 0, 400, 250)

屏幕仍然被截断

[/编辑]

[\编辑2017 11 04 09:20] 以下代码有效：

import wx

class MainEdit(wx.Frame):
    def __init__(self, parent=None, title="Main Edit"):
        wx.Frame.__init__(self, parent, -1, title=title)
        txt_size = (300, 150)
        txt_style = wx.VSCROLL|wx.HSCROLL|wx.BORDER_SIMPLE|wx.TE_MULTILINE
        self.txt_A = wx.TextCtrl(self, size=txt_size, style=txt_style)
        self.txt_B = wx.TextCtrl(self, size=txt_size, style=txt_style)
        cmd_refresh = wx.Button(self, wx.ID_REFRESH)

        main_sizer = wx.BoxSizer(wx.VERTICAL)
        main_sizer.Add(self.txt_A, flag=wx.ALL, border=10)
        main_sizer.Add(self.txt_B, flag=wx.ALL, border=10)
        main_sizer.Add(cmd_refresh, flag=wx.ALL, border=10)
        self.SetSizerAndFit(main_sizer)


if __name__ == '__main__':
    app = wx.App()
    frame = MainEdit()
    frame.Show()
    app.MainLoop()

如您所见，我已删除了面板。但是，我被告知here“框架应该只有一个孩子，一个小组。”

那么构建wxPython程序的推荐方法是什么？[/ EDIT]

Answer 1

此代码修复了它。我在MainFrame中添加了一个sizer并将面板放入其中。它仍然没有回答为什么原始代码在某些PC上运行而不是我的

import wx

class MainEdit(wx.Frame):
    def __init__(self, parent=None, title="Main Edit"):
        wx.Frame.__init__(self, parent, -1, title=title)
        panel = MainPanel(self)
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(panel)
        self.SetSizerAndFit(sizer)

class MainPanel(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        txt_size = (300, 150)
        txt_style = wx.VSCROLL|wx.HSCROLL|wx.BORDER_SIMPLE|wx.TE_MULTILINE
        self.txt_A = wx.TextCtrl(self, size=txt_size, style=txt_style)
        self.txt_B = wx.TextCtrl(self, size=txt_size, style=txt_style)
        cmd_refresh = wx.Button(self, wx.ID_REFRESH)

        main_sizer = wx.BoxSizer(wx.VERTICAL)
        main_sizer.Add(self.txt_A, flag=wx.ALL, border=10)
        main_sizer.Add(self.txt_B, flag=wx.ALL, border=10)
        main_sizer.Add(cmd_refresh, flag=wx.ALL, border=10)
        self.SetSizer(main_sizer)


if __name__ == '__main__':
    app = wx.App()
    frame = MainEdit()
    frame.Show()
    app.MainLoop()

请注意，必须在框架级别而不是面板上完成调整。事实上，如果我在这里用SetSizer替换SetSizerAndFit，我会遇到与我开始时相同的问题。

在黑暗中拍摄可能让你感到厌恶的事：

让框架变大，

wx.Frame.__init__(self, parent, -1, title=title, size=(250, 520))

遗漏，也许是不必要的，

#~ self.Fit()

此代码适用于Ubuntu 16.4，Python 3.5.2，wx.Python 4.0.0b2 gtk2（phoenix

import wx

class MainEdit(wx.Frame):
    def __init__(self, parent=None, title="Main Edit"):
        wx.Frame.__init__(self, parent, -1, title=title)
        panel = MainPanel(self)
        print (3,self.GetScreenRect())

class MainPanel(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        print (1,self.GetScreenRect())
        txt_size = (300, 150)
        txt_style = wx.VSCROLL|wx.HSCROLL|wx.BORDER_SIMPLE|wx.TE_MULTILINE
        self.txt_A = wx.TextCtrl(self, size=txt_size, style=txt_style)
        self.txt_B = wx.TextCtrl(self, size=txt_size, style=txt_style)
        cmd_refresh = wx.Button(self, wx.ID_REFRESH)

        main_sizer = wx.BoxSizer(wx.VERTICAL)
        main_sizer.Add(self.txt_A, flag=wx.ALL, border=10)
        main_sizer.Add(self.txt_B, flag=wx.ALL, border=10)
        main_sizer.Add(cmd_refresh, flag=wx.ALL, border=10)
        self.SetSizerAndFit(main_sizer)
        print (2,self.GetScreenRect())
if __name__ == '__main__':
    app = wx.App()
    frame = MainEdit()
    frame.Show()
    app.MainLoop()

初始屏幕显示为：

尝试上面编辑的代码并观察屏幕尺寸是否适应变化看它是否给你任何里程注意：我选择使用parent而不是frame

wx Python适合控件的屏幕
