Listbox, slow problems in debug mode (no release)

[hurricane]

Hi all,

i have a performance issue with a Listbox and about 100 items into...

this is the code:

Code: Select all


   for(size_t i = 0; i < sounds.size(); i++){

      CEGUI::Listbox* list = static_cast<CEGUI::Listbox*>(wmgr.getWindow("Root/SoundSelector/FolderList"));
      CEGUI::ListboxTextItem* item = new CEGUI::ListboxTextItem(sounds.at(i));
      item->setSelectionBrushImage("Vanilla-Images", "GenericBrush");
      item->setID(i);
      list->addItem(item);

   }



This problem is only in debug mode...the window is too slow (also application loading).... in release mode is all ok.

cegui log?

only this "property" error:

ps ONLY the window with listbox is "in Matrix mode", others windows NO

thanks in advance, Martin

If you complain about the speed, having a lot of text displayed is known to be slow in debug mode. I use a listbox for chat messages, when there are like 100 (short) messages, my FPS drop very hard.

This should change with the renderer rewrite CE does right now.

For the errors, maybe there is something wrong with the looknfeel you use.

are there any patch to fix this issue (at the moment)? thx

Hi,

The thing about debug builds - especially for CEGUI, for some reason - is that they are inherently slower (this is due obviously to the fact the code is not optimised by the compiler, and also the fact that more runtime checks are performed). We have a very heavy use of STL containers, and I think in debug mode, this is what kills us the most - though it should be less pronounced from 0.7.0 onwards.

There is not, and can never be, a 'solution' whereby debug runs anywhere near the speed of an optimised build - otherwise there would be no need for optimised builds, right? What you can do is, depending upon your needs, customise the build options such that you get the level of debugging information you need, but without so much of the other baggage (so you might disable the runtime checks, as one simple example). And yes, I am fully aware that trying to debug something that runs like molasses is almost an impossible task, as is trying to debug optimised builds

are there any patch to fix this issue (at the moment)? thx

As mentioned, there is no 'fix' per-se, but work is being done on CEGUI's performance and other areas, and so we should have mitigated these adverse affects, at least a little, with the new renderer model that's being developed at the moment. Currently there is only a 99% complete implementation for the OpenGL API, which I hope to finish this weekend, then start the other renderers - and even then this will require a fair amount of testing time before a release is made. There is no 'patch' for this, since it's a somewhat fundamental change to the way the underlying rendering is done by CEGUI (though if you do want to take a look, the code is in the renderer-rewrite-devel branch of subversion, and is being discussed starting at this post: http://www.cegui.org.uk/phpBB2/viewtopi ... 7414#17414).

ok thanks CE for reply. now it's all more clear. Then i ll use some pre-compiler directives to limit "cegui's stress" in debug mode.
