The problem with showing wxStaticText in Python while using wxFormBuilder

Question

I'm new at the python learning, so I can't quite understand some things. So I'm trying to make a small desktop app, and I didn't want to make all the design with a code, so I have found the thing like wxFormBuilder, which is very suits me. The problem is when I have made all the "design" of the window, it looks fine in the wxFormBuilder, but when I copy all the code in PyCharm and launch the program - everything is working perfectly fine, exept no one wxStaticText is showing. I really can't understand what is the problem, because I have used Sizers and all these things, even tried to modify the most of code that relates to text labels, but still no text. I'm applying screenshots from PyCharm and wxFormBuilder of how does it look. Also there is the code:

# -*- coding: utf-8 -*-

    def __init__(self, parent):
        wx.Frame.__init__(self, parent, id=wx.ID_ANY, title=u"FinanceC", pos=wx.DefaultPosition, size=wx.Size(700, 389),

I tried to create just clear Form in wxFormBuilder with just the text on it, and open it in PyCharm - it worked. I also tried to change in my main form the style of font, size, different parameters, tried to edit different parameters in code, still nothing. I also tried to change the position of wxStaticText and size of it, it changes in PyCharm and there is more free whitespace when i make that (and this free space is right where it must be), but still no text showing. Also tried using english language in text - still the same. Remarkable, that i have tried to replace wxStaticText with wxTextCtrl, and it worked - the text was showing, but the element is not quite that I need.

Answer 1

I have figure it out what was the problem. Default color of text was white, and the background of form is white. In code for every StaticText you need to add: self.m_staticText1.SetForegroundColour('black') So it will appear.

Answer 2

The actual problem is that you have set both the foreground and background color of the entire window to be the same:

self.SetForegroundColour(wx.SystemSettings.GetColour(wx.SYS_COLOUR_WINDOW))
self.SetBackgroundColour(wx.SystemSettings.GetColour(wx.SYS_COLOUR_WINDOW))

Your call to set the foreground of StaticText would not be necessary if the main window's foreground/background were not the same.

The problem with wxFormBuilder is that if you change the fg color property in the dropdown list, you cannot change it back to the default. While it will state "Window", it still generates the SetForegroundColour() call. The same is true of the bg property -- once set, you can't remove it. The only way to fix that is to open the .fbp file it created, find the fg property for the window, and remove the wxSYS_COLOUR_WINDOW value (do the same for the bg property). Once you have done that, wxFormBuilder will no longer generate code to set the foreground/background of the window and your static text control will display correctly without the need to set it's foreground color.
