Datepickerctrlgeneric

[Chris_Keo]

There is a bug in datepickerctrlgeneric.

When the event wx.EVT_DATE_CHANGED is triggered, it breaks the tabbing order. So it skips over widgets when tabbing. I even used SetTabIndex ().

I know it’s a bug because when I switch to datepickerctrl and trigger the event, the tabbing goes in order of the widgets.

Anybody know why?

Hi,

Which platform and which version of wxPython are you using?

I tested the code below using Python 3.10.6 + wxPython 4.2.0 gtk3 (phoenix) wxWidgets 3.2.0 on Linux Mint 21.1

The tab order was the same, before and after a wx.EVT_DATE_CHANGED event was triggered.

import wx
import wx.adv

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwds):
        kwds["style"] = kwds.get("style", 0) | wx.DEFAULT_FRAME_STYLE
        wx.Frame.__init__(self, *args, **kwds)
        self.SetSize((400, 200))
        self.SetTitle("DatePickerCtrlGeneric")
        self.main_panel = wx.Panel(self, wx.ID_ANY)
        main_sizer = wx.BoxSizer(wx.VERTICAL)
        self.datepicker_ctrl = wx.adv.DatePickerCtrlGeneric(self.main_panel, wx.ID_ANY)
        main_sizer.Add(self.datepicker_ctrl, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.TOP, 16)
        self.text_ctrl = wx.TextCtrl(self.main_panel, wx.ID_ANY, "")
        main_sizer.Add(self.text_ctrl, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.TOP, 16)
        bottom_sizer = wx.BoxSizer(wx.HORIZONTAL)
        main_sizer.Add(bottom_sizer, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.BOTTOM | wx.TOP, 16)
        self.button_1 = wx.Button(self.main_panel, wx.ID_ANY, "button_1")
        bottom_sizer.Add(self.button_1, 0, wx.RIGHT, 32)
        self.button_2 = wx.Button(self.main_panel, wx.ID_ANY, "button_2")
        bottom_sizer.Add(self.button_2, 0, 0, 0)
        self.main_panel.SetSizer(main_sizer)
        self.Layout()
        self.Bind(wx.adv.EVT_DATE_CHANGED, self.OnDateChanged, self.datepicker_ctrl)

    def OnDateChanged(self, event):
        print(event.GetDate())


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

    app.MainLoop()

Using windows,python 3.7.4, wx 4.2 phoenix

Could it be due to python 3.7 ?

Could it be due to python 3.7 ?

It’s possible, but I would have thought that UI differences would be more likely due to Windows vs Linux/GTK. Unfortunately, I don’t have any Windows PCs on which to test.

Does explicitly setting the tab order, as shown in the code below, make any difference?

import wx
import wx.adv

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwds):
        kwds["style"] = kwds.get("style", 0) | wx.DEFAULT_FRAME_STYLE
        wx.Frame.__init__(self, *args, **kwds)
        self.SetSize((400, 200))
        self.SetTitle("DatePickerCtrlGeneric")
        self.main_panel = wx.Panel(self, wx.ID_ANY)
        main_sizer = wx.BoxSizer(wx.VERTICAL)
        self.datepicker_ctrl = wx.adv.DatePickerCtrlGeneric(self.main_panel, wx.ID_ANY)
        main_sizer.Add(self.datepicker_ctrl, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.TOP, 16)
        self.text_ctrl = wx.TextCtrl(self.main_panel, wx.ID_ANY, "")
        main_sizer.Add(self.text_ctrl, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.TOP, 16)
        bottom_sizer = wx.BoxSizer(wx.HORIZONTAL)
        main_sizer.Add(bottom_sizer, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.BOTTOM | wx.TOP, 16)
        self.button_1 = wx.Button(self.main_panel, wx.ID_ANY, "button_1")
        bottom_sizer.Add(self.button_1, 0, wx.RIGHT, 32)
        self.button_2 = wx.Button(self.main_panel, wx.ID_ANY, "button_2")
        bottom_sizer.Add(self.button_2, 0, 0, 0)
        self.main_panel.SetSizer(main_sizer)
        self.Layout()
        self.Bind(wx.adv.EVT_DATE_CHANGED, self.OnDateChanged, self.datepicker_ctrl)
        self._setTabOrder()

    def _setTabOrder(self):
        order = (self.datepicker_ctrl,
                 self.text_ctrl,
                 self.button_1,
                 self.button_2)

        for i in range(len(order) - 1):
            order[i+1].MoveAfterInTabOrder(order[i])

    def OnDateChanged(self, event):
        print(event.GetDate())


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

I’ll probably be accused of blowing my own trumpet here, but you could give my minidatepicker a whirl, with the caveat, that I don’t think it has been tested on Windows.
You can find the latest version using this link:

A wx.DatePickerCtrl with a customisable format

DatePickerCtrl is seemingly stuck with a MM/DD/YYYY format, great for our North American chums but which makes it virtually useless for the rest of us. Hopefully others will find this useful as you can decide the date format you wish to use and elect to use a calendar in your own language too. Let me know if there are errors and omissions. Apparently I’m still not permitted to upload a file, so I’ll have to paste it! """ MiniDatePicker.py A custom class that looks like the wx.DatePi…

Here I stole the code from @RichardT (sorry Richard) and replaced the date widget.
On Linux it behaves itself.

import wx
#import wx.adv
import minidatepicker as MDP

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwds):
        kwds["style"] = kwds.get("style", 0) | wx.DEFAULT_FRAME_STYLE
        wx.Frame.__init__(self, *args, **kwds)
        self.SetSize((400, 200))
        self.SetTitle("MiniDatePicker")
        self.main_panel = wx.Panel(self, wx.ID_ANY)
        main_sizer = wx.BoxSizer(wx.VERTICAL)
        format = (lambda dt: (f'{dt.Format("%A %d-%m-%Y")}'))
        #self.datepicker_ctrl = wx.adv.DatePickerCtrlGeneric(self.main_panel, wx.ID_ANY)
        self.datepicker_ctrl = MDP.MiniDatePicker(self.main_panel, -1, formatter=format)

        main_sizer.Add(self.datepicker_ctrl, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.TOP, 16)
        self.text_ctrl = wx.TextCtrl(self.main_panel, wx.ID_ANY, "")
        main_sizer.Add(self.text_ctrl, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.TOP, 16)
        bottom_sizer = wx.BoxSizer(wx.HORIZONTAL)
        main_sizer.Add(bottom_sizer, 0, wx.ALIGN_CENTER_HORIZONTAL | wx.BOTTOM | wx.TOP, 16)
        self.button_1 = wx.Button(self.main_panel, wx.ID_ANY, "button_1")
        bottom_sizer.Add(self.button_1, 0, wx.RIGHT, 32)
        self.button_2 = wx.Button(self.main_panel, wx.ID_ANY, "button_2")
        bottom_sizer.Add(self.button_2, 0, 0, 0)
        self.main_panel.SetSizer(main_sizer)
        self.Layout()
        #self.Bind(wx.adv.EVT_DATE_CHANGED, self.OnDateChanged, self.datepicker_ctrl)
        self.Bind(MDP.EVT_DATE_CHANGED, self.OnDateChanged, self.datepicker_ctrl)

    def OnDateChanged(self, event):
        print(event.GetDate())


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

Wow, so much respect for people who can build these tools.

Looks awesome, going to test it this noon! Thanks for the response.

How can I turn off the blue rectangle and “today: 6/30/2023” in the drop down calendar
