            Cross-platform file names and wxString::ToStdString()
            Asked 2021-Jun-01 at 15:40

            I want to handle files in a cross-platform application using wxWidgets 3.1. I rely on some functions that only accept the file name as an std::string.

            On Windows, I can simply use wxString::ToStdString() and everything is fine.

            On Linux (Ubuntu 20.04 LTS), the conversion fails and returns an empty string when there are "special" characters in the file name or path (e.g., the default downloads directory on a French Ubuntu "Téléchargement").

            When I specify the following converter explicitly on Linux, the conversion succeeds: std::string str = wxs.ToStdString(wxMBConvUTF8());

            But this does not work on Windows and scrambles the "special" characters.

            I guess, I could write platform-dependent code to deal with this, but that defeats the purpose of the toolkit.

            I have done quite a bit of research on this but I am utterly confused now. I thought wxString uses std::string under the hood in a Unicode wxWidgets build (which I am using)? Why is this (apparently) platform-dependent? What am I missing?

            Here is a minimal example that will pop up three messageboxes: The first one shows the wxString correctly, the second one shows no string (because the conversion fails), the third one shows the string once the conversion is done explicitly. On Windows, the first two boxes show the string correctly and the last one shows the wrong characters for the two 'é'.

            You should be using wxString::fn_str(), which returns a suitable string in a suitable type to be used as a filename.

            If you use wxString::ToStdString() on Windows, everything is no longer "fine" if you have e.g. cyrillic letters in the string and your locale is German. The conversion fails.

            wxPython migration from 4.0.7 to 4.1.0: ListCtrl error while event handling
            Asked 2021-May-12 at 11:09

            I'm currently migrating from wxPython 4.0.7 to wxPython 4.1.0. This changes the wx version from 3.0.x to 3.1.x.

            Tl;dr: Using a wx.ListCtrl I sometimes get an error when I call event.Skip() inside a wxEVT_SIZE event handler. To Skip() or not to Skip()? (i.e. whats the default event handling for a wxEVT_SIZE and do I need it?)

            Long Version:

            Using wx.ListCtrl with event.Skip inside the wxEVT_SIZE handler produces an error in some of my forms (so I think there must be more to it). Now, I couldn't strip any of the occurrences down to have a minimal example, since the error kinda disappears randomly when I remove (seemingly) unrelated parts of the code. The error even disappears (sometimes) when I replace a long label with a shorter label. However, changing the Frame or Panel size doesn't change anything.

            Here is, what I found out:

            • The error is definitely linked to the usage of the wx.ListCtrl class
            • The error only occurs, when a function is bound to the wxEVT_COMMAND_LIST_ITEM_ACTIVATED event, though an empty handler (with or without Skip()) is enough to provoke the error.
            • The error only occurs when a function is bound to the wxEVT_SIZE event
            • The error only occurs when I call event.Skip() in the wxEVT_SIZE handler

            It seems like I can simply remove the event.Skip() call inside the wxEVT_SIZE handler and be done, but the relevant C++ Code seems like there is more going on.

            Here is the error (note: the error does not crash the wxApp):

            I believe this assert can only be triggered if a handler calls Bind() from its event handler, but skips the event, i.e. pretends that the event wasn't handled at all. In an ideal world, this should be possible and I think the assert is actually over-eager and needs to be relaxed, but for now, if you really need to do it like this, you must either:

            1. Postpone calling Bind() by using CallAfter().
            2. Or avoid calling event.Skip().

            (note that the assert won't be always triggered in this case, you also need to delete a handler that was previously connected to the same object shortly before).

            But generally speaking you should call Skip() unless you have fully processed the event and don't want any other handlers, either those in the base class or the built-in ones, to run after yours. For wxEVT_SIZE it means that you've performed the re-layout of the window yourself and don't want the base class to do anything. So the solution (1) is better because it can be used even if you do want the base class handler to run.

            What bind to use to detect FlatNotebook tab page closing vis FNB_X_ON_TAB
            Asked 2021-May-07 at 08:36

            I'm using wxPython FlatNotebook widget and have enabled the FNB_X_ON_TAB style. But what bind event triggers on this action (clicking the x in the tab to close it)?

            ANSWER

            Answered 2021-May-07 at 08:36

            You are forcing the widget Id in the Bind command, to be 100.
            But nothing has been set to an Id of 100.
            You have options:

            • Set the notebooks Id to 100
            • Leave the Id out of the Bind, assuming you have only 1 FlatNotebook
            • Get the Id in the Bind
            • Bind to the widget not self

            So:

            • notebook = fnb.FlatNotebook(panel, 100)
            • self.Bind(fnb.EVT_FLATNOTEBOOK_PAGE_CLOSED, self.popup_close_tab)
            • self.Bind(fnb.EVT_FLATNOTEBOOK_PAGE_CLOSED, self.popup_close_tab, id=notebook.GetId())
            • notebook.Bind(fnb.EVT_FLATNOTEBOOK_PAGE_CLOSED, self.popup_close_tab)

            It's a pretty flexible system, however serendipity had left the building, when you made one of the few choices, that wouldn't work. :)

            I'm relatively new to both C++ and Wx, so I've been doing a lot of blundering around trying to get this to work over the past few hours, but I seem to have hit a figurative brick wall with this issue.

            This code compiles with no errors, but when run, it does nothing. It simply remains running until terminated (e.g. with Ctrl-C), but a window never opens.

            Your error is due to using DECLARE_EVENT_TABLE but not using any wxBEGIN_EVENT_TABLE/wxEND_EVENT_TABLE, i.e. you never define your event table nor connect any event handlers.

            I don't know anything about SFML, so I can't really help you with the rest, but apparently drawing is supposed to be done from your wxEVT_PAINT handler -- once you connect it -- by just calling sf::RenderWindow::Display().

            C++ Errors C2893, C2780, C2672 when using future, promise, detached thread
            Asked 2021-Jan-08 at 23:54

            I have got a class named cApp.

            I want to run CheckProcessList() in the background until the program terminates. So i thought, well, lets run it in a detached thread until ~cApp(). I made a bool to break out of the loop in CheckProcessList(). In ~cApp I set the bool true m_bTerminateThread = true to break out and wait for the promise m_barrierFuture->wait() that the thread has ended execution. After breaking out i set the promise barrier.set_value() that the thread is now ending execution. Now ~cApp can finish execution. Or at least that is my understanding of the things i want to achieve and how to do it. Well, can't be right since i get Compiler Errors.

            Why did it want to check if the thread finished in the first place? Because the program breaks at runtime when it terminates and the thread is at that moment in GetProcId(). If it is sleeping in the moment of termination the program does not break.

            I searched msdn and stackoverflow for answers but i do not get anything out of it that i can understand. I am using VS2019 and C++14. Thank you guys in advance.

            I don't know to which lines your errors pertains (you didn't show this) but I suspect at least above statement is wrong.

            If you pass an address of a thread procedure to std::thread constructor and this procedure is a non-static member function the next argument after must be an address of the object you refer to (after all a non-static member function must have an instance that it is called on behalf of). std::promise is not a type which contains such a function pointer type &cApp::CheckProcessList so this cannot work.

            There are many issues here. To answer the main question of why this hangs your program, in the OnClose method you call Destroy() and then delete the frame (which includes m_text_time). Meanwhile, your thread is sleeping and when it wakes up, it will try change the label for m_text_time which no longer exists. I'm not sure why this causes deadlock instead of a segfault, but this is the problem. So you can make this work poorly and problematically by simply changing the order to:
