wxPython自定义对话框加载不正确

Question

I am trying to create a custom dialog to display information. It is activated on a button press, and that mechanism is working perfectly. However, the dialog itself is broken. Any help is appreciated.

import wx

class ForgotPass(wx.Dialog):

    def __init__(self, *args, **kwargs):
         super(ForgotPass, self).__init__(*args, **kwargs) 

        self.InitUI()

    def InitUI(self):
        self.panel = wx.Panel(self)
        self.sizer = wx.BoxSizer(wx.VERTICAL)

        self.title = wx.StaticText(self.panel, label='Forgotten Your Password?', style=wx.ALIGN_CENTER)
        self.title.SetFont(wx.Font(8, wx.DEFAULT, wx.NORMAL, wx.BOLD, underline=True))  # Underlined & Bold
        self.sizer.Add(self.title)

        self.text = wx.StaticText(self.panel, label="Contact 'TheHiguty' via ingame PM to have your password reset!", style=wx.ALIGN_CENTER)
        self.sizer.Add(self.text)

        self.SetSizer(self.sizer)
        self.SetSize((200, 150))
        self.SetTitle('Forgotten Your Password')
        self.Center()
        self.Show(True)

def main():
    app = wx.App(False)
    ForgotPass(None)
    app.MainLoop()

if __name__ == "__main__":
    main()

However rather than displaying the text correctly, I get this:

Any help to fix this issue is greatly appreciated!

Answer 1

Add self.sizer.Fit(self.panel) after self.SetSizer(self.sizer) to fix the problem. Although, if you do so, you'll find that the horizontal width is too small, so you might want to expand that. Complete code with fix:

import wx

class ForgotPass(wx.Dialog):

    def __init__(self, *args, **kwargs):
        super(ForgotPass, self).__init__(*args, **kwargs) 

        self.InitUI()

    def InitUI(self):
        self.panel = wx.Panel(self)
        self.sizer = wx.BoxSizer(wx.VERTICAL)

        self.title = wx.StaticText(self.panel, label='Forgotten Your Password?', style=wx.ALIGN_CENTER)
        self.title.SetFont(wx.Font(8, wx.DEFAULT, wx.NORMAL, wx.BOLD, underline=True))  # Underlined & Bold
        self.sizer.Add(self.title)

        self.text = wx.StaticText(self.panel, label="Contact 'TheHiguty' via ingame PM to have your password reset!", style=wx.ALIGN_CENTER)
        self.sizer.Add(self.text)

        self.SetSizer(self.sizer)
        self.sizer.Fit(self.panel)
        self.SetSize((400, 150))
        self.SetTitle('Forgotten Your Password')
        self.Center()
        self.Show(True)

def main():
    app = wx.App(False)
    ForgotPass(None)
    app.MainLoop()

if __name__ == "__main__":
    main()

Although, there is a way to create dialogs that look cleaner and looks more native to whatever OS the program is run on: use wx.MessageBox

Here's a simple example:

import wx

class MainWindow(wx.Frame):
    def __init__(self, parent):
        super(MainWindow, self).__init__(parent)

        self.sizer = wx.BoxSizer(wx.VERTICAL)

        self.button = wx.Button(self, wx.ID_ANY, label="Test")
        self.sizer.Add(self.button)
        self.Bind(wx.EVT_BUTTON, self.password_dialog, self.button)

        self.SetSizer(self.sizer)
        self.sizer.Fit(self)
        self.SetTitle('Test')
        self.SetSize((100, 100))
        self.Centre()
        self.Show(True)

    def password_dialog(self, event):
        wx.MessageBox(
            'Contact `TheHiguty` blah blah blah',
            'Forgotten your password?',
            wx.OK|wx.ICON_ERROR)

if __name__ == '__main__':
    app = wx.App()
    MainWindow(None)
    app.MainLoop()

Answer 2

I understand that this is an older question, but I would like to note what I use for custom dialog boxes and do not have the "noise / icon" (at least in my opinion). This is working with wxPython 2.9.5.0.

This is the code I use:

from wx.lib.pubsub import pub

def showConfirmDlg(message, caption, flag=wx.OK|wx.ICON_NONE):
    msg = wx.MessageDialog(None, message=message,
                       caption=caption, style=flag)
    msg.ShowModal()
    msg.Destroy()

pub.subscribe(showConfirmDlg, 'dialog.confirm')

As you can see in the snippet I can use this function repeatedly for various messages and eliminate the need for multiple function definitions. To show the dialog box with the text in your example I would do this:

def onButtonPress(self, event):
    pub.sendMessage('dialog.confirm',
        message="Forgot your password?\n Contact 'TheHiguty' (rest of text)",
        caption="Forgot Password?") # Could even just put caption=""

For further re-usability options you can replace the "flag=wx.OK|wx.ICON_NONE" with just "flag" and add "flag=wx.OK|(whatever style)" to your function call.

For more examples regarding Python and wxPython I highly recommend Mike Driscoll's blog site The Mouse vs The Python. I have found it amazingly informative and have learned a lot about wxPython from Mr Driscoll.

Hope this helps you and others!

--EDIT-- I should mention that I found wx.ICON_NONE by accident while trying to remove icons from my message boxes myself.
