[英]Combobox selected and display value in another combobox Tkinter
[英]Save the selected value of a combobox in wxpython
我正在使用wxpython设计gui,我的代码的一点好处是我有一个fram类
声明,也声明了我想根据组合框更改其值的变量
选择。 我做了以下:
class myMenu(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title, size=(900, 700))
self.ct = 0
self.phaseSelection = ""
self.opSelection = ""
self.instSelection = ""
self.orgSelection = ""
panel = wx.Panel(self, -1)
panel.SetBackgroundColour('#4f3856')
phasesList = ["preOperations", "inOperations", "postOperations"]
self.cbPhases = wx.ComboBox(panel, 500, 'Phase', (50, 150), (160,-1), phasesList, wx.CB_DROPDOWN)
self.Bind(wx.EVT_COMBOBOX, self.OnPhaseSelection, id = self.cbPhases.GetId())
这是“ OnPhaseSelection”事件的代码:
def OnPhaseSelection(self, event):
self.phaseSelection = self.cbPhases.GetValue()
我想将所选值保存在变量“ self.phaseSelection”中,并用
空字符串作为初始值,那么我想将此变量与新保存的值一起使用,但是当我运行时
程序中,该变量包含组合框的默认值! 所以请问是什么问题
我的工作 ?
我不确定这是怎么回事。 看起来应该可以使用。 我复制了其中的大部分内容,并将其放入可在Windows上运行的可运行示例中:
import wx
########################################################################
class MyForm(wx.Frame):
#----------------------------------------------------------------------
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, "Tutorial")
panel = wx.Panel(self, wx.ID_ANY)
self.ct = 0
self.phaseSelection = ""
self.opSelection = ""
self.instSelection = ""
self.orgSelection = ""
phasesList = ["preOperations", "inOperations", "postOperations"]
self.combo = wx.ComboBox(panel, choices=phasesList)
self.combo.Bind(wx.EVT_COMBOBOX, self.onCombo)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.combo)
panel.SetSizer(sizer)
#----------------------------------------------------------------------
def onCombo(self, event):
"""
"""
self.phaseSelection = self.combo.GetValue()
print self.phaseSelection
#----------------------------------------------------------------------
# Run the program
if __name__ == "__main__":
app = wx.App(False)
frame = MyForm().Show()
app.MainLoop()
