我刚开始使用wxPython并且遇到绑定问题。
通常,我发现绑定按钮事件的示例都是使用self.Bind(wx.EVT_BUTTON, self.OnWhatEverFunction, button)
完成的。我有一个框架内部有一个面板和一个按钮,我尝试过的结果总是一个闪烁的框架,它瞬间出现,就是这样。由于代码不是那么多,我在这里附上它,希望你们中的一个能告诉我解决我的小问题的方法。
提前致谢, 托马斯
#!/usr/bin/python
import wx
class CPFSFrame(wx.Frame):
def __init__(self, parent, title):
super(CPFSFrame, self).__init__(parent, title=title,
style = wx.BORDER | wx.CAPTION | wx.SYSTEM_MENU | wx.CLOSE_BOX,
size=(350, 200))
panel = wx.Panel(self, -1)
pNumberLabel = wx.StaticText(panel, -1, 'Project number: ')
pNumberText = wx.TextCtrl(panel, -1, '', size=(175, -1))
pNumberText.SetInsertionPoint(0)
pNameLabel = wx.StaticText(panel, -1, 'Project name: ')
pNameText = wx.TextCtrl(panel, -1, '', size=(175, -1))
pNameText.SetInsertionPoint(0)
pButton = wx.Button(panel, label='Create')
pButton.Bind(wx.EVT_BUTTON, self.OnCreate)
sizer = wx.FlexGridSizer(cols=2, hgap=6, vgap=6)
sizer.AddMany([pNumberLabel, pNumberText, pNameLabel, pNameText, pButton])
panel.SetSizer(sizer)
statusBar = self.CreateStatusBar()
def OnCreate(self, evt):
self.Close(True)
self.Centre()
self.Show()
if __name__ == '__main__':
app = wx.App()
CPFSFrame(None, title='Create New Project Folder Structure')
app.MainLoop()
答案 0 :(得分:0)
您需要将“self.Show()”方法放在代码的 init 部分中。起初我以为OnCreate()正在运行,如果是,那么它会立即关闭框架,所以你什么都看不到。我会把它叫做OnClose而不是。这是一个有效的例子:
import wx
class CPFSFrame(wx.Frame):
def __init__(self, parent, title):
super(CPFSFrame, self).__init__(parent, title=title,
style = wx.BORDER | wx.CAPTION | wx.SYSTEM_MENU | wx.CLOSE_BOX,
size=(350, 200))
panel = wx.Panel(self, -1)
pNumberLabel = wx.StaticText(panel, -1, 'Project number: ')
pNumberText = wx.TextCtrl(panel, -1, '', size=(175, -1))
pNumberText.SetInsertionPoint(0)
pNameLabel = wx.StaticText(panel, -1, 'Project name: ')
pNameText = wx.TextCtrl(panel, -1, '', size=(175, -1))
pNameText.SetInsertionPoint(0)
pButton = wx.Button(panel, label='Create')
pButton.Bind(wx.EVT_BUTTON, self.OnClose)
sizer = wx.FlexGridSizer(cols=2, hgap=6, vgap=6)
sizer.AddMany([pNumberLabel, pNumberText, pNameLabel, pNameText, pButton])
panel.SetSizer(sizer)
statusBar = self.CreateStatusBar()
self.Show()
def OnClose(self, evt):
self.Close(True)
if __name__ == '__main__':
app = wx.App()
CPFSFrame(None, title='Create New Project Folder Structure')
app.MainLoop()
