[Solved] CELayoutEditor layout to code

[pokemoen]

I can't find any ready made routines in CEGUI to load the xml layout generated by the layouteditor.. Do I need to parse the file myself or have I overlooked something?

I mean... the following code from the demo project could be generated from the xml file right?

Code: Select all

PushButton* btn = (PushButton*)WindowManager::getSingleton().createWindow((utf8*)"TaharezLook/Button", (utf8*)"QuitButton");
      sheet->addChildWindow(btn);
      btn->setText((utf8*)"Quit!");
      btn->setPosition(Point(0.035f, 0.0f));
      btn->setSize(Size(0.1f, 0.036f));

loop all the widgets in the xml file and maybe manually subscribe eventlisteners to each... I really can't imagine such a function isn't available somewhere... any place someone can point me to?

Thanks in advance,
Alex

and ofcourse just after I post in the forum I find it myself...

Code: Select all

00175 Window* WindowManager::loadWindowLayout(const String& filename, const String& name_prefix, const String& resourceGroup, PropertyCallback* callback, void* userdata)

Is that it?

Alex

Hmmm... it works in CELayoutEditor...any ideas?

Thanks,

At a glimpse this layout looks fine.
could you post your codeline that loads it ?

[pokemoen]

Sure:

Code: Select all

      SchemeManager::getSingleton().loadScheme((utf8*)"../data/schemes/TaharezLook.scheme");
      System::getSingleton().setDefaultMouseCursor((utf8*)"TaharezLook", (utf8*)"MouseArrow");

      Window* sheet;
      WindowManager::getSingletonPtr()->loadWindowLayout((utf8*)"../data/layouts/menus.xml",(utf8*)"");
      menuLayout = WindowManager::getSingleton().getWindow((utf8*)"Menus");
      gameLayout = WindowManager::getSingletonPtr()->loadWindowLayout((utf8*)"../data/layouts/game.xml");
      cardSelectLayout = WindowManager::getSingletonPtr()->loadWindowLayout((utf8*)"../data/layouts/cardselect.xml");
      sheet->addChildWindow(menuLayout);
      sheet->addChildWindow(gameLayout);      
      sheet->addChildWindow(cardSelectLayout);
      displayLayout(1);


At first all 3 layouts were loaded like 'gameLayout' and 'cardSelectLayout' above, then I did some experimenting with menuLayout... So, that's why they're different in the above code..

But anyway, the error is logged in (the first) loadWindowLayout().

Maybe it's a path issue. Is the "distance" to data and CEGUI files (schemes, images and such) the same from the editor and your own code when you load a layout?

But it might be something else, since CEGUI has some clear errors on such cases...

Good luck anyway!

[pokemoen]

Nope, that's not it..
So I turned on INSANE logging and that helps a little :/

Code: Select all

25/05/2005 09:13:15 (InfL2)   ---- Beginning loading of GUI layout from 'menus.xml' ----
25/05/2005 09:13:18 (InfL2)   Window 'Menus' of type 'DefaultWindow' has been created.
25/05/2005 09:13:18 (InfL2)   Window 'login_window__auto_titlebar__' of type 'TaharezLook/Titlebar' has been created.
25/05/2005 09:13:18 (InfL2)   Window 'login_window__auto_closebutton__' of type 'TaharezLook/CloseButton' has been created.
25/05/2005 09:13:18 (Error)   Exception: WindowManager::loadWindowLayout - An unexpected error occurred while parsing gui-layout file 'menus.xml'.


So the default window with the close_button is created and it crashes after that.. next line in the layout file is "<Property Name="AbsoluteRect" Value="l:47.000000 t:18.000000 r:527.000000 b:564.000000" />"; are those values pixels?

Okay, some code I thought was irrelevant was causing the program to crash. I removed it (it were some old eventlistener subscribers), now it runs, but the error still appears in the logfile and I only get a blue screen without a GUI...

This is my log now:

Code: Select all

Hi,

Are you using Xerces or TinyXML for the XML file parsing?

Thanks,

CE.

[pokemoen]

Xerces (2.5.0)

[CrazyEddie]

It's failing part way through construction of the FrameWindow object. I got nothing but wild guesses really, so...

Have you loaded at least one font and, if you're using anything other than CVS HEAD, set a font to be used as a default font?

CE.

[pokemoen]

Eddie... you're the KING of wild guesses
I went back to my fontloading code and it was indeed _after_ the layout loading code.. which brought me to a "Window* sheet" not being inited right, etc.
Anyway, it's working now, thanks again!
CEGUI is great!
