QuickGui && Shoggoth

Hey,

I am currently trying to build QuickGui in order to replace RBGui with it. Now I added this line to the library

createManual("RttTex", "Default", TEX_TYPE_2D, 512, 512, 0, PF_R8G8B8, TU_RENDERTARGET)

and it compiles, though I get these warnings (havn't been there with eihort):

And a runtime assertion fails in ogresharedprt.h, expression pRep.

The program breaks in xutility.h at the end of this function

void __CLR_OR_THIS_CALL _Adopt(const _Container_base *_Parent)
{ // adopt this iterator by parent
if (_Mycont != _Parent)
{ // change parentage
_Lockit _Lock(_LOCK_DEBUG);
_Orphan_me();
if (_Parent != 0 && _Parent->_Myfirstiter != _IGNORE_MYITERLIST)
{ // switch to new parent
_Mynextiter = _Parent->_Myfirstiter;
((_Container_base *)_Parent)->_Myfirstiter = this;
}
_Mycont = _Parent;
}
}

What do I have to do in order to make QuickGui work with Shoggoth?

I remember another thread about the same issue, I think it will have the answer:

http://www.ogre3d.org/phpBB2addons/viewtopic.php?t=5824

Unfortunately not. I read the thread before and did whats described there, but the assertion fails somewhere else I think. Does the SVN version of the gui compile against eihort or shoggoth?

It works with 1.4.7, thats what I'm currently using. It looks like all your warning are not qgui related, ie vector/memory/xutility.

What is the purpose of the _Lockit object, and what does _Orphan_me do? Which line throws the exception?

Also, this is trivial, but is there really a need to make a cast here?

((_Container_base *)_Parent)->_Myfirstiter = this;

What is "this"? What type of object. What is a _Container_base and who is trying to adopt it?

The code is from xutility.h, I can't tell you anything about it, but I know the warnings are generated within QuickGUIQuadContainer.cpp. I commented out some lines and the warnings disappeared. I will have a look where the exception is thrown in ogre, til now I only know its after the scene has been loaded and startRendering() has been called.

Btw, I forgot to mention: The warnings appear when compiling the library, the assertion fails when running the demo.

I'm assuming from the silence in the thread I linked to, that some people have gotten quickgui working with Shoggoth.

In any case, I'm working on a new render system that follows RBGUI style rendering (texture cache), and QuickGUIQuadContainer.cpp will be removed when its finished.

K, since I have other things to do I'm just gonna wait this one out
Thx for your time.

Hi,

I' m using QuickGUI with Shoggoth, cvs(few weeks max...), no pblm.
maybe the demo itself is broken, not sure, but the lib works fine.

I'm also using QuickGUI with Shoggoth (CVS from a week or two ago) without problems (other than the inability to hide scrollbars - but that's probably a universal problem with all version of Ogre)...

Actually I tried the version that was said to be stable in the wiki, maybe I should try the svn version.

Yup, works fine with SVN version
One strange bug though, I get this view every time I hover over a textbox:



Seems like there is a special mouse pointer for text boxes but instead of that one it displays the whole quickgui texture.

You need to rebuild your skinset and its texture. Delete qgui.skinset and SkinSet.qgui.png and re-run the app.
