[SOLVED] Issue with Loading/Unloading Resources
Posted: Tue May 13, 2014 14:30
Here is what I am trying to do.
1) Load base resources A.
2) Load extra resources B.
3) Unload extra resources B.
4) Load extra resources C that are just different versions of resources B (same names, different pictures)
I can't find a good way to do this.
I found this thread http://cegui.org.uk/forum/viewtopic.php?f=10&t=6586 was helpful and relevant.
My suggestion is that CEGUI should have a better way to handle loading and unloading blocks of resources. I want to unload all images relevant to B, but not unload anything in A. That's really tough to do right now.
Anyway, back to my problem. My workaround is:
1) Load base resources A.
2) Load extra resources B.
3) Unload all resources.
4) Load base resources A.
5) Load base resources C.
The issue I am having with this is I get access violation reading location 0xABABABAB when attempting to reload the layout in resources A. I can reload the schemes, imagesets, and fonts without exception.
CEGUI/Window.cpp where the exception is thrown
My call stack:
My unload and reload process:
Finally my CEGUI.log
Any help or suggestions (if there is an easier way to do this) would be welcome.
Thanks.

My unload and reload process:
Code: Select all
// unload all
CEGUI::System::getSingleton().getDefaultGUIContext().setRootWindow(NULL);
WindowManager::getSingleton().destroyAllWindows();
SchemeManager::getSingleton().destroyAll();
FontManager::getSingleton().destroyAll();

// reload resources A
for (string const& s : ui.GetSchemes()) {

}
for (string const& s : ui.GetImagesets()) {

}
for (string const& s : ui.GetFonts()) {

}
root = WindowManager::getSingleton().loadLayoutFromFile(ui.GetLayout(), Path::Get().LayoutFileResourceGroupName(mod_name, ui.GetLayout())); // ** THIS LINE **
if (root == nullptr) throw runtime_error("Layout file (" + ui.GetLayout() + ") failed to load.");
Finally my CEGUI.log
