Error: window object does not exists

[saurabh]

Hi:

I am trying to load multiple layouts and switching between them on the basis of button click event. TO be specific, this is a multi page application.
I loaded all the layout and set one of them to be visible. When i click on one button of this layout then i expect some event but even though cegui.log logs that

"10/10/2009 13:43:33 (InfL1) ---- Successfully completed loading of GUI layout from 'casesScreen.layout' ---- " but when i connect button to eventHandler , my program crashes with loggin this error message...
10/10/2009 13:43:33 (Error) Exception: WindowManager::getWindow - A Window object with the name 'LogoutBtn' does not exist within the system

I am confused that what is happening. Earlier i was able to connect and run things properly in the same manner.

CEGUI.LOG:

10/10/2009 13:43:33 (InfL1) Started creation of Imageset from XML specification:

10/10/2009 13:43:33 (Error) Exception: WindowManager::getWindow - A Window object with the name 'LogoutBtn' does not exist within the system


my layout file, casesScreen.layout has following window in it.

<!-- Case/Background/ -->
<Window Type="Vanilla/Button" Name="LogoutBtn" >
<Property Name="UnifiedMaxSize" Value="{{1,0},{1,0}}" />
<Property Name="NormalTextColour" Value="FF00FF00" />
<Property Name="Text" Value="Logout Button" />
<Property Name="UnifiedAreaRect" Value="{{0.00126559,0},{0.163043,0},{0.0993667,0},{0.243479,0}}" />
<Property Name="NormalImage" Value="set:logoutbtn image:ButtonUp" />
<Property Name="HoverImage" Value="set:logoutbtn image:ButtonDisabled" />
<Property Name="PushedImage" Value="set:logoutbtn image:ButtonHighlighted" />
<Property Name="DisabledImage" Value="set:logoutbtn image:ButtonDisabled" />
<Property Name="UseStandardImagery" Value="False" />
</Window>


My code piece that crashes is as follows:

CEGUI::WindowManager *wMgr = CEGUI::WindowManager::getSingletonPtr();
CEGUI::Window *case_logoutBtn = wMgr->getWindow((CEGUI::utf8*)"LogoutBtn");
case_logoutBtn->subscribeEvent(CEGUI::PushButton::EventClicked,
CEGUI::Event::Subscriber(&ExitListener::logoutHandle, this));


This is how i set any window visible.... All the layouts are attached to mainwindow....
menu = mainWindow->getChildAtIdx(3);
menu->setVisible(true);
Mainwindow is attached to root window which in turn is attached to sheet.


Questions:
1. What might be causing this crash?
2. Is there any other and better way of writing a multipage application in CEGUI-OGRE?

Any help is highly appreciated... as i am totally stuck for last few hours...

Thanks
Saurabh

Hi,

Clearly, the window does not exist at the time when you're trying to access it. Please set the CEGUI logging level to CEGUI::Informative, re-run the application, and post the full CEGUI.log file - and also, surround the log content with code tags, like this:

[code]
<paste log content here>
[/code]

CE.

I am using this code line to set the CEGUI logging level to informative but program just crashes before logging anything.
CEGUI::Logger::getSingleton().setLoggingLevel( CEGUI::Informative );

If comment these lines then it works fine...

My CEGUI.log without informative set is pasted below and it says that all the layouts are successfully loaded...

v0.5.1 is quite old so I'm not sure if this is relevant, but to setup logging for v0.6+ you need to first create the logging class, like so:

Code: Select all

new CEGUI::DefaultLogger();
CEGUI::Logger::getSingleton().setLoggingLevel(CEGUI::Informative);

Hi:

Setting to loglevel 2 works for me... I used the same old line but no idea why it worked this time and did not worked previously...

The mistake was that i was giving a name to layout while loading so that i can retrieve that back later using that name and i did not know that i need to prefix layout name to any window in that layout in order to retrieve that.

Thanks
Saurabh

Cool, glad you have it fixed - and this was one of the issues I was going to look in the log for
