@SirShane: what do you think we can take look at the next release?

I'm looking forward it

The gui awesome great work. However, I can't seem to figure a nice was of determining whether a button has been pressed.

Skattjakt,

The only thing I can think of that might be an issue is mismatched .lib files. Make sure your directories are setup in VS2005 to point to the cvs version of ogre.

Woah!
I went through all of the libs I was linking and I saw this lib-file called user32.lib. I thought "humm, I'm not linking this one to a directory. Maybe it's linked by an environment variable?" And ofcourse it was. I found it in \Microsoft Platform SDK for Windows Server 2003 R2\Lib and I noticed its name was User32.lib and not user32.lib.

I changed to the upper case U in VS2005 and now it's working perfectly!

I didn't even know it was case sensitive!

Thanks a lot!

And the Gui totally rocks! I'm speechless!

Really? I would have sworn it isn't case sensitive.

Skattjakt · Post by **Skattjakt** » Tue Jul 24, 2007 3:40 pm

Just one thing.
While I'm exploring the Ogre Gui Sample everytime I press something in the menu i gives a message in the console window:

For example:

WARNING: Texture instance 'Gui_Target_33' was defined as manually loaded, but no
manual loader was provided. This Resource will be lost if it has to be reloaded

And the same goes for all the drop-down menues like 'Bool Value'!

Yeah, me to!
But I'm 100% positive that that was everything I changed!

I am glad you got it fixed, but that is too strange, what OS are you using?

@Skattjakt

My guess is that when you changed something in the properties of a project visual studio decides whether or not to recompile the project (if you use just "Compile" and not "Recompile" option)
and with the last change it does re-compiled whatever was wrong with your compilation. One of your previous compilation did not recompiled the stuff that cosed the problem.

I may be wrong at all ...

Skattjakt · Post by **Skattjakt** » Tue Jul 24, 2007 4:03 pm

Oh my!

Just to straight things out I changed it back to the lower case and rebuilded the solution. Still worked! So I must have done something else before after all. And now I don't even know how I fixed - That's even more annoying!

(But I'm still glad it works)

@vasil

I always rebuild!

@Skattjakt
If you always rebuild then it is really annoying!
Do not worry it happens to all of us sometimes. ;-)

I can probably put up another release this week. There aren't that many new features, since I haven't had time to work on it much. But I did fix a lot of the things the community has requested (Like mouse over highlighting for the menus and stuff).

Eldarion · Post by **Eldarion** » Tue Jul 24, 2007 7:58 pm

yeah that sounds great. i'm looking forward to use it in my application.

Now that I have built RBGui alright. Is it safe for me to switch to the latest source release of ogre instead of the latest cvs version of ogre?

Is it just the DLL's that are vital?

SirShane · Post by **SirShane** » Wed Jul 25, 2007 8:50 am

You have to use the CVS version of Ogre with the GUI. There are some interface changes (namely _setSeparateSceneBlending) that the GUI requires to work. You can't use the latest release source code, and then DLLs compiled from CVS.

Horizon · Post by **Horizon** » Wed Jul 25, 2007 10:32 am

SirShane: Will you be putting this project up on sourceforge sometime, too? There's a lot of little things that would be nice to fix, which would be easy to submit as patches.

For one thing, it would be great to have a default location for RBGUI, so we could set the build-properties right once and for all. I propose something like:

Code: Select all

-OGRE
 -ogrenew
 -ogreaddons
 -etc
-Right Brain Games
 -Mocha
 -RBGUI

Or something like that.

Okay. But do I HAVE to use the HEAD or can I use the Maintenance branch?

SirShane · Post by **SirShane** » Wed Jul 25, 2007 6:54 pm

I think you need to use HEAD. Although i'm not really sure what the maintenance branch includes, I don't think it would have the _setSeparateSceneBlending fix.

First of all, I just want to say that this GUI looks incredible!

I'm sorry if this is already included as a widget or something, but I haven't started using Ogre yet, so I can't test it. But, is it possible to render a 3D object or entire scene inside a Window? For example, when building a level editor, I would like to provide a viewport that displays the currently selected model which can be rotated and scaled. Or better yet, would it be possible to add this as a feature to the Open File dialog so that selecting a .mesh file renders the model in a pane to the right or as a thumbnail like with images?

Keep up the great work!

SirShane · Post by **SirShane** » Thu Jul 26, 2007 1:09 am

You can render a 3D view into a window by rendering a scene into a texture as usual, and then using that texture as an image in a window.

BloodyFanatic · Post by **BloodyFanatic** » Sat Jul 28, 2007 3:11 pm

SirShane, I think I found a nasty bug:

When you try this code,

Code: Select all

RBGui::OgreBrush* ogreBrush = new RBGui::OgreBrush( mSceneMgr, mViewport );
delete ogreBrush;
ogreBrush = new RBGui::OgreBrush( mSceneMgr, mViewport );

the last line will throw this exception:

Code: Select all

OGRE EXCEPTION(4:ItemIdentityException): Resource with the name __GUI_DEFAULT_TEXTURE__ already exists. in ResourceManager::add at ..\src\OgreResourceManager.cpp (line 113)

It seems that you forgot to release the '__GUI_DEFAULT_TEXTURE__' texture.

I would fix it on my own, but i don't know how...

SirShane · Post by **SirShane** » Sat Jul 28, 2007 8:21 pm

Thanks. I fixed it. Just to let you know, you should never call delete on any object that comes from the GUI. All objects from the GUI inherit from a class called Mocha::Object, which is reference counted. Use Mocha::RefPointer to work with them.

Is it possible to create a window without caption?
And can I make the background transparent? Some sort of Alpha blending?

Thnak you in advance..

SirShane · Post by **SirShane** » Mon Jul 30, 2007 3:46 am

You can create a window without a caption by making a new border that doesn't have a title bar. You can also add transparency by having a border with an alpha channel. The default theme "Monochrome Grape" uses the alpha channel to create a small shadow around the edges of the default window border.

There is also a method named 'setOpacity' on the window. This is not a good way to change the opacity of a window, however, because it is used by the window animator classes to fade in and out. It shouldn't be used manually.
