QueueEvent, when used in wxWindow, is a protected method. Yes, but it is public in wxEvtHandler. And you are right. You may use myWindow->GetEvtHandler()->QueueEvent() The documentation for wxWindow class states: ... ProcessEvent() itself can't be called for wxWindow objects as it ignores the event...

Doublechecked the wxWidgets docs: virtual void wxEvtHandler::QueueEvent(wxEvent* event) [virtual] This method is similar to ProcessEvent() but while the latter is synchronous, i.e. the event is processed immediately, before the function returns, this one is asynchronous and returns immediately while...

Need help writing “backgroundless” widget for wxWidgets

Hi there. I asked this question on stackoverflow 3 days back, but still not received any answers, so I'm posting it here. My question is concerned with GTK2 and wxWidgets (actually wxGTK). In wxGTK all controls have grey background by default and it is impossible to remove it. I have a textured pane...

You should always use QueueEvent methods within secondary threads IMHO. Why don't you just create your evt object on heap?

SIGSEGV. How to react on event with sender destruction.

The problem is:
Object1 sends event using ProcessEvent() method;
Object2 handles the event and should delete Object1 instantly.
How to implement it? I'm trying to avoid delayed destruction schemes (callbacks, etc.).

Language is c++.

Вот спасибо! С Вашими заголовками действительно компилируется. А то в сети ходят 3 архива инклюдов GDI+, где LockBits вызывается с референсом, а не указателем в кач. первого аргумента!

Если Вы используете MinGW, откомпилировать wxWidgets с GDI+ (пока) не получится. Вы можете сделать прозрачность и без GDI+. Смотрите пример в samples/images. Код в файле image.cpp, начинающийся после комментария "// Then, draw colourful alpha-blended stripes".
