To clarify what lowjoel was saying: "#pragma" is part of the standard. "#pragma once" is not. "#pragma" is for issuing compiler specific directives not covered by the standard. VC, for instance, supports warning disabling like this: "#pragma warning ( disable : 4101)". Also, as I said before, VC isn...

The wikipedia article is incorrect. #pragma once also works on GCC 3.4+ (it was un-deprecated) and inclusion guards and #pragma once aren't quite the same thing. The result is the same but #pragma once improves compilation speed (see this Games from Within article for details). Use both to get the s...

Nope, there is no EVT_MOUSE_IS_STILL_OUTSIDE event. wxScrolledWindow does it using a derived wxTimer that continually fires until an EVT_ENTER_WINDOW occurs.

wxScrolledWindow is scrolling single lines which is exactly what it should do. If you want it to move more than a pixel set your scroll increment to something bigger than a pixel (using SetScrollRate ). Changing this behavior is somewhat complicated but the meat of it is in scrlwing.cpp (wxAutoScrol...

Although you are extremely lacking in details, I bet you're looking for something like this: wxFile file("somefile.txt"); char buffer[1025]; file.Read(buffer, 1024); buffer[1024] = '\0'; wxString some_iso8859_1_string(buffer, wxConvISO8859_1); Also, I'm sure there is a much cleaner way (wxStringBuff...

Vadim's reply: I've just tried it here (VC7.1, HEAD) and it works as expected. I'm not in UTC-9 of course, but I'm not in UTC neither... I have really no idea why it doesn't work for two of you. I suspect you may have to break out the debugger if you want to get to the bottom of the issue. I'm a bit...

I tried tracing the differences between the two. I didn't see anything glaringly wrong but the path is slightly complicated to trace. wxDateTime uses the default copy constructor so I doubt the issue is there. The first main difference I would think would be that the first one creates a wxDateTime i...

Topic: Adding Days to wxDateTime
Replies: 2
Views: 803

Rather than using numbers I suggest using wxDateTime::Jan, wxDateTime::Feb, etc. because there is no guarantee that wxDateTime::Jan will always equal 0. You can also easily add directly to wxDateTime::Jan if you need to iterate through or specifiy arbitrary months. For example for(wxDateTime::Month ...

You need a manifest to enable XP style themes (you can get it by including wx/msw/wx.rc in your resource file).

The bytes needed depends on the encoding. Not all encodings support all codepoints. I'm unsure what encoding wxString uses internally.

You could fake motion just fine. Technically, the windowing environment just adds the mouse motion vector to the current mouse position rapidly to simulate motion and you could do the same (wxIdleEvent may be a starting point for this) although the user could "fight" you over the position which woul...

Use wxWindow::WarpPointer. Note, you can't do this on Mac because, as the documentation says: "Apple Human Interface Guidelines forbid moving the mouse cursor programmatically".

wxWidgets seems to get it defined for me by itself. Are you placing the include after the inclusion of <wx/wx.h> (you should be)? Just to be thorough, here is a list of my project wide preprocessor defines: WIN32;_DEBUG;_CONSOLE;__WXMSW__;__WXDEBUG__
