对话框中的wx.DatePickerCtrl忽略在wxGTK上点击return后输入的值

wxpython python

Frank Niessink · 技术社区 · 15 年前

我有一个带有日期选择器控件的对话框。按日期选择器中的enter键关闭对话框(如预期)。但是,日期选择器不会拾取用户在wxGTK上输入的值。运行附加的示例,单击按钮,使用键盘在日期选择器中输入新日期,然后按enter键。print语句显示日期选择器的上一个值,而不是刚刚输入的值。

在wxMSW上,它按预期工作。在这两种情况下都使用wxPython 2.8.10.1。

有什么想法吗?工作?

import wx

class Dialog(wx.Dialog):
    def __init__(self, *args, **kwargs):
        super(Dialog, self).__init__(*args, **kwargs)
        self.datepicker = wx.DatePickerCtrl(self)
        self.button = wx.Button(self, label='OK')
        self.button.SetDefault()
        self.button.Bind(wx.EVT_BUTTON, self.onButton)
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.datepicker)
        sizer.Add(self.button)
        self.SetSizerAndFit(sizer)

    def onButton(self, event):
        print self.datepicker.GetValue()
        self.Close()


class Frame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super(Frame, self).__init__(*args, **kwargs)
        self.button = wx.Button(self, label='Press me to open dialog')
        self.button.Bind(wx.EVT_BUTTON, self.onButton)

    def onButton(self, event):
        dialog = Dialog(self, size=(200,30))
        dialog.Show()   

app = wx.App()
frame = Frame(None, size=(200,50))
frame.Show()
app.MainLoop()

datepicker.Navigate() datepicker.GetValue() . 这似乎奏效了。

这似乎解决了这个问题:

import wx

class Dialog(wx.Dialog):
    def __init__(self, *args, **kwargs):
        super(Dialog, self).__init__(*args, **kwargs)
        self.datepicker = wx.DatePickerCtrl(self)

        # On wxGTK, intercept all keys:
        if wx.Platform == '__WXGTK__':
            comboCtrl = self.datepicker.GetChildren()[0]
            comboCtrl.Bind(wx.EVT_KEY_DOWN, self.onKey)

        self.button = wx.Button(self, label='OK')
        self.button.SetDefault()
        self.button.Bind(wx.EVT_BUTTON, self.onButton)
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.datepicker)
        sizer.Add(self.button)
        self.SetSizerAndFit(sizer)

    def onButton(self, event):
        print self.datepicker.GetValue()
        self.Close()

    def onKey(self, event):
        keyCode = event.GetKeyCode()
        if keyCode == wx.WXK_RETURN:
            # Move to the next field so that the contents of the text control,
            # that might be edited by the user, are updated by the datepicker:
            self.datepicker.Navigate()
            # Next, click the default button of the dialog:
            button = self.GetDefaultItem()
            click = wx.CommandEvent()
            click.SetEventType(wx.EVT_BUTTON.typeId)
            wx.PostEvent(button, click)
        elif keyCode == wx.WXK_TAB:
            self.datepicker.Navigate(not event.ShiftDown())
        else:
            event.Skip()


class Frame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super(Frame, self).__init__(*args, **kwargs)
        self.button = wx.Button(self, label='Press me to open dialog')
        self.button.Bind(wx.EVT_BUTTON, self.onButton)

    def onButton(self, event):
        dialog = Dialog(self, size=(200,30))
        dialog.Show()   

app = wx.App()
frame = Frame(None, size=(200,50))
frame.Show()
app.MainLoop()
