wxWidgets Discussion Forum

Hello, I was wondering what to use to cast (void *) to (wxString *)! Suppose I have the following function: namespace util { size_t write_callback(char *ptr, size_t size, size_t nmemb, void *userdata) { reinterpret_cast<wxString *>(userdata)->Append(ptr, size * nmemb); // <--- Cast (1): Should I use...

Interesting std::thread simulation.
I will give it a try.

Thank you.

Thank you.

I just thought, it may exist in the toolkit and just not documented, and I am not seeing it.
Since I am using wxWidgets, why not using such a function (if it exists) as for example I am using wxString all the time instead of std::string.

Hello, I need to know if there is a way to call a function in a new thread as std::thread does using just wxWidgets as it does for wxEvtHandler::CallAfter (simple and easy and accepts lambda functions as well). I don't need to write the entire wxThread derived class declaration and implementation fr...

Hello, I have a simple application that loads Firebird database records and inserts them in a wxDataViewListCtrl . I have made a simple test to check that my application works as expected by filling that database with over 1 million records and tried again, this time the application GUI is completel...

Yes indeed I forgot to call Layout() after each AddOperateur().
And thank you for fixing the vertical scrollbar problem, "Chapeau expression".
it seems that I have to learn more about scrolled windows.

You're adding 3 items and there is enough room, so why should there be a horizontal scrollbar? Actually I am adding more than 3 (12), that's why the horizontal scrollbar should appear. If you want me to try it out, make the code compilable. Yes sure, please, and sorry about the previous code. This ...

Hi,
What is your wxWidgets version?
Can you try to add one more panel the scrolled window?

Thank you.

I already added at least four items. It is just the scrollbars are not showing.

Hello, I have sub-classed wxGenericProgressDialog to add more widgets on it using a loop. When a new item is added the dialog expands, and I have controlled it to expand no more than 3 item horizontally. The main window that holds these controls is a wxScrolledWindow inside the main dialog of course...

OK, I am gonna try it out

Hello, I have an associated wxTextValidator and wxFloatingPointValidator for some wxTextCtrl . As the validator is only invoked for keystrokes, I want to add extra control for clipboard paste events. Where to intercept the paste event and pass the validation to the associated validator for validatio...

It worked but I had to take note and store the previous settings in a member string variable on application initialization: bool MyApp::OnInit() { if (!wxApp::OnInit()) { return false; } #ifdef __WXMSW__ const int cnDataSize = GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SSHORTDATE, NULL, 0); TCHAR szL...

interesting, I'm gonna try it out.

I guess I have no other choice.
