Set wx.Frame size (wxPython - wxWidgets)

问题:

I am new to wxPython and I am finding some issues while seting a given size for both frames and windows (widgets). I have isolated the issue to the simplest case where I try to create a Frame of 250x250 pixels.

Running the code I get a window of an actual size of 295 width by 307 height (taking into consideration the Windows´s top window bar)

I am using Python 2.7 in Windows 10.

What am I missing?

#!/bin/env python
import wx

# App Class
class MyAppTest7(wx.App):

    def OnInit(self):

        frame = AppFrame(title = u'Hello World', pos=(50, 60), size=(250, 250))
        frame.Show()
        self.SetTopWindow(frame)
        return True

# AppFrame
class AppFrame(wx.Frame):
    def __init__(self, title, pos, size):
        wx.Frame.__init__(self, parent=None, id=-1, title=title, pos=pos, size=size)


if __name__ == '__main__':
        app = MyAppTest7(False)
        app.MainLoop()

An addtional test to further show issue:

#!/bin/env python
import wx

class MyApp(wx.App):
    def OnInit(self):
        self.frame = MyFrame(None, title="The Main Frame")
        self.SetTopWindow(self.frame)
        self.frame.Show(True)
        return True

class MyFrame(wx.Frame):
    def __init__(self, parent, id=wx.ID_ANY, title="", pos=wx.DefaultPosition, size=(400,100), style=wx.DEFAULT_FRAME_STYLE, name="MyFrame"):
        super(MyFrame, self).__init__(parent, id, title, pos, size, style, name)
        self.panel = wx.Panel(self)

if __name__ == "__main__":
    app = MyApp(False)
    app.MainLoop()

And the result:

As you can see displayed window (frame) has 482 pixels (-see Paint's bottom bar-) instead of the expected 400.

Window size measured in pixels

回答1:

Add this before your call to app.MainLoop():

import wx.lib.inspection
wx.lib.inspection.InspectionTool().Show()

That will let you easily see the actual size (and other info) for each widget in the application, like this:
