signature? I'm not quite sure what you mean. The only way I know how to pass global variables, like the Pointers class that I initiated in main.cpp, would be by pointer assigning when I call a function

If there's a better way please tell!

global is just a variable that points to the global Pointer class that is declared in main.cpp main.cpp #include "main.h" #include "wxVertigo_Frm.h" #include "Pointers.h" #include "rand.h" #include "temp.h" IMPLEMENT_APP(MainApp) bool MainApp::OnInit() { initImageHandlers(); seed(); // Seed random g...

Absolutely, thank you for your attention Simple format of the code I'm talking about: part of main.cpp Pointers *pointers = new Pointers(); pointers->ScreenResolution = ::wxGetDisplaySize(); pointers->tempAccess = new temp; Pointers.h #ifndef _POINTERS_ #define _POINTERS_ class RenderGLCanvas; class...

Allow wxThread to access global data

I'm having this bothersome problem when I create a thread and try to access global data. Basically I create the wxThread passing a pointer to a global class with a variable, and in the Entry() function I try to access that variable. The problem I get every time is "Access Violation" saying that it c...

This is what I think is happening, when the main thread calls the static IFS class it creates an IFS class for that thread, now when the worker thread calls the static IFS thread it creates ANOTHER IFS class! Am I correct? And if so how do I access the first threads static IFS class instead of creat...

At the very bottom of the IFS class a static IFS class called IFS is created: class IFS { public: int SierpinskiTriangleIter, TriAnglesIter, PentagonIter; IFS() { SierpinskiTriangleIter = 10000; TriAnglesIter = 25000; PentagonIter = 50000; }; ~IFS(){}; struct RGBquad { int r, g, b, a; }; struct Vert...

Alright, rendering from another thread: Out the window : ) It's okay though, I've been fiddling with my code and created a custom event handler for events sent from the thread. Now when the thread deems it necessary to render it sends a command to the main thread telling it to render. Now the only p...

Great! Thanks for those explanations! That really cleared my misunderstanding up. What I'm trying to accomplish with this thread is running an idleling window thread on top of the already inplace window of the main application. My idea of the loop that uses the loop test with testDestroy is as such:...
