This error happens when a wxString is being implicitly cast to an integer. Make sure no argument expects an integer but is recieving a wxString.

A stack trace would certainly be helpful.

If you define a sub-object as an object with a parent which owns the object then yes, wxWidgets will almost always handle deletion for you. An object that is simply a member of another object does not fit this criteria. Generally with wxWidgets it will automatically delete objects that you've specif...

It should be OK actually. std::string and wxString are just a bunch of bytes and don't check for zeros etc. so you should be ok with any encoding as long as you remember to explicitly specify the length. And UTF-8 doesn't really contain \0's in strings, it is used for specifying the end of a string...

I don't believe wxWidgets has support to send raw printer commands directly. If you're on Windows I think WriterPrinter is what you are looking for (the Code Project also has an article that looks like it may be of at least some use). You'll have to figure out the raw printer command methods yoursel...

If the printer is actually turning off I'd suspect it was a driver issue rather than an issue with your code.

It's actually wxString::mb_str(), rather than wxString::mbstr(). Also, you should probably be specifying the target encoding like so: And std::string has no concept of UTF-8 so I'd recommend avoiding stuffing a UTF-8 string in one.

Still getting them :(. The ones I'm getting are particularly obnoxious because they aren't actually pop-up/-under windows but pseudo-windows embedded in the page itself. Certainly there has to be a better third-party monitoring service or, even better, a local monitoring solution like those suggeste...

If it has a parent or is a top-level window that lets its Close() destroy the window.

You should use Destroy() (g_pGLCanvas->Destroy()) for objects derived from wxEvtHandler (it prevents lingering events from being processed using a non-existent event handler). Also, since your wxGLCanvas is most certainly a child of another wxWindow or wxWindow derived class you can safely not do an...

I know of no way to change the alignment with the standard wxStatusBar. You'll probably need to derive a new class from wxStatusBar. In the OnSize for this new class use GetFieldRect to position and size a left/right/center aligned wxStaticText (and remember to Skip() the event). Create a new functi...

Oh, forgot to mention that is only if you want to do it after the parent window and children have been created. If you SetFont() (like vdell said) before you create the children, they will inherit the font. Someone correct me if I'm wrong on this (I've always assumed this is what the docs where tryi...

Something like this will probably do the trick: std::stack<wxWindow*> window_stack; window_stack.push(parent_window); while(!window_stack.empty()) { wxWindow* current = window_stack.top(); window_stack.pop(); current->SetFont(font); wxWindowList list = parent_window.GetChildren(); for(WindowList::No...

This has been dicussed ad nauseum on the wx-dev mailing list. See the archives if you want to know more about it.

You can get it in millimeters from wxPageSetupDialogData. I don't know of a "pixel" perfect way.
