CEGUI (Crazy Eddie's GUI) Forums

in my project,there have socket recv thread,when recv some package,then go to processPackage

DWORD WINAPI ProcessThread(LPVOID params)
{
....
ProcessPackage(...);
}


ProcessPackage(...)
{
//when in here invoke createWindow method the programe is crash!!!!
WindowManager& winMgr = WindowManager::getSingleton();

Window* frame = winMgr.getWindow("Demo/Window");

Window* button = winMgr.createWindow("OgreTray/Button","test");

button->setSize(UVector2(cegui_absdim(50),cegui_absdim(50)));
button->setPosition(
UVector2(cegui_absdim(150),cegui_absdim(150)));
button->setProperty("Text", tagList->RoomVector[i].RoomName);
frame->addChildWindow(button);
}

why is crash!!!!! cegui dosn't support mulit-thread?

CEGUI is not thread safe, you have to use synchronisation primitives and/or queues to make this work.

whatever you render platform base on DirectX or OpenGL or Opengl ES ,
these are support multi render content to make multi thread Render devices work.
I get this same problem when use cegui in IOS platform { Opengl ES 1.1 }, then to create multi render content for easy render thread to solove this problem.

sorry for my English , I'm Chinese.
