creating a debug window

[jchmack]

Hi im really new to CEGUI so please forgive my inexperience.

Im trying to create a debug window that will contain alot of my Debug
information. FPS, IP adress, number of poly's ETC.

Im using the ogre3d graphics engine btw.

I can initialize CEGUI fine:

Code: Select all

void game4::InitializeCEGUI()
{
   //create CEGUI
   mGUIRenderer = new CEGUI::OgreCEGUIRenderer(mWindow, Ogre::RENDER_QUEUE_OVERLAY, false, 3000, mSceneMgr);
   mGUISystem = new CEGUI::System(mGUIRenderer);

   //Set Logging
   CEGUI::Logger::getSingleton().setLoggingLevel(CEGUI::Informative);

   //CEGUI settings
   CEGUI::SchemeManager::getSingleton().loadScheme((CEGUI::utf8*)"TaharezLookSkin.scheme");
   mGUISystem->setDefaultFont((CEGUI::utf8*)"BlueHighway-12");
   mEditorGuiSheet= CEGUI::WindowManager::getSingleton().createWindow((CEGUI::utf8*)"DefaultWindow", (CEGUI::utf8*)"Sheet"); 
   mGUISystem->setGUISheet(mEditorGuiSheet);

   //Setup mouse
   mGUISystem->setDefaultMouseCursor((CEGUI::utf8*)"TaharezLook", (CEGUI::utf8*)"MouseArrow");
   CEGUI::MouseCursor::getSingleton().setImage("TaharezLook", "MouseMoveCursor");
   
   unsigned int WindowWidth   = Ogre::StringConverter::parseUnsignedInt(settings["width"].data());
   unsigned int WindowHeight   = Ogre::StringConverter::parseUnsignedInt(settings["height"].data());

   CEGUI::MouseCursor::getSingleton().setPosition(CEGUI::Point(
      (mWindow->getWidth() / 2) - 16,
      (mWindow->getHeight() / 2) - 16)
      );

   //Create button
   quitButton = (CEGUI::PushButton*)CEGUI::WindowManager::getSingleton().createWindow("TaharezLook/Button", (CEGUI::utf8*)"HP");
   mEditorGuiSheet->addChildWindow(quitButton);
   quitButton->setPosition( CEGUI::UVector2(cegui_reldim(0.1f), cegui_reldim( 0.1f)));
    quitButton->setSize( CEGUI::UVector2(cegui_reldim(0.1f), cegui_reldim( 0.1f)));
   quitButton->setText("Click Here To See Your HP");

   //Register for events
   CEGUI::WindowManager& wmgr = CEGUI::WindowManager::getSingleton();
   wmgr.getWindow((CEGUI::utf8*)"HP")->subscribeEvent(CEGUI::PushButton::EventClicked, CEGUI::Event::Subscriber(&game4::GUIButtonPressed, this));
   
}


and i can create my debug window fine:

Code: Select all

void game4::UseDebugWindow()
{
   DebugWindow = (CEGUI::Window*) CEGUI::WindowManager::getSingleton().createWindow("TaharezLook/FrameWindow", (CEGUI::utf8*)"Debug");
   mEditorGuiSheet->addChildWindow(DebugWindow);
   DebugWindow->setPosition( CEGUI::UVector2(cegui_reldim(0.25f), cegui_reldim( 0.25f)));
   DebugWindow->setSize( CEGUI::UVector2(cegui_reldim(0.5f), cegui_reldim( 0.5f)));
   DebugWindow->setText("Debug Window");
   
   DebugListBox = (CEGUI::Listbox*) CEGUI::WindowManager::getSingleton().createWindow("TaharezLook/Listbox", (CEGUI::utf8*)"Listbox");
   DebugListBox->setPosition(CEGUI::UVector2(cegui_reldim(0.1f), cegui_reldim( 0.1f)));
   DebugListBox->setSize( CEGUI::UVector2(cegui_reldim(0.8f), cegui_reldim( 0.8f)));
   DebugListBox->setText("DebugListBox setText");
   DebugListBox->setShowVertScrollbar(true);

   DebugTime = new CEGUI::ListboxTextItem("TEST TEXT");
   DebugListBox->addItem(DebugTime);

   DebugFPS = new CEGUI::ListboxTextItem("TEST TEXT2");
   DebugListBox->addItem(DebugFPS);

   DebugWindow->addChildWindow(DebugListBox);
}


the problem comes when i try to update my elements in my debug window:

Code: Select all

void game4::UpdateDebugWindow(float _time)
{
   cout << "UpdateDebugWindow is being called" << endl;

   static float time = 0;
   time+=_time;
   DebugTime->setText("Time: " + Ogre::StringConverter::toString(time));

   DebugFPS->setText("FPS: " + Ogre::StringConverter::toString( mWindow->getLastFPS() ));

   DebugWindow->update(_time);
   DebugListBox->update(_time);
}


The information only updates when i click each item individually. I believe i am injecting inputs properly.

And i have been putting these lines everywhere to try to fix my problem:

DebugWindow->update(_time);
DebugListBox->update(_time);

Why isnt my info updating? Im pretty sure that the update function is being called every frame.

I apologize for the long post. Thx to all who help in advance =)

[jchmack]

what exactly causes CEGUI to update an element... Ive been working on and off for about 2 days on this and it still doesn't make sense. Im calling the setText every frame... So im pretty sure that CEGUI is either not updating the information or just not rendering it. Sigh...

I was typing something else when i noticed the problem in your code

Listboxes require you to tell them when you change their items. For the listbox you should call 'DebugListBox->handleUpdatedItemData()' at the end of your 'UpdateDebugWindow' method.

When you click an item, this request is probably called by cegui itself. That's why you see the change on a click.

HTH.

Thank you very much Script. Works exactly the way i need it . But im also wondering something. If CEGUI doesn't automatically update the listbox im guessing it's because the listbox wasn't designed for each element to be changing alot. It seems more suited for something like a chatbox. What kind of window or CEGUI element would you reccomend for text information that is very dynamic like FPS.

[scriptkid]

Good to hear that you got it too work You are right about the reason for this: if you have very dynamic text, you might choose StaticText widgets. For example in your situation:

Code: Select all

//Create FPS stat
fpsText = CEGUI::WindowManager::getSingleton().createWindow("TaharezLook/StaticText", (CEGUI::utf8*)"FPS");
// Hide the border and background to make it look like text-only
fptText->setProperty("BackgroundEnabled", "False");
fptText->setProperty("FrameEnabled", "False");


After that just call 'setText' on it. See that i don't cast 'fpsText' to anything, since StaticText is 'just' (mapped to) a DefaultWindow.

Good luck

funny paradox sentence but it's true

[scriptkid]

LOL

I've updated WidgetGalore's Listbox section with this information; it's not an obvious solution.

[jchmack]

One more question guys is there somewhere on the wiki or in the source that i can find a list of the many properties that can be set by the setProperty() function? I cant navigate the wiki very well yet .

edit: i found this:

http://www.cegui.org.uk/wiki/index.php/ ... owsLook%29

and am satisfied. But i would be open to anymore lists.

[scriptkid]

Well that list is very complete The coloured values come from the looknfeel definitions. This is the same list for the Taharez look:
http://www.cegui.org.uk/wiki/index.php/SetProperty

HTH.

[Rackle]

I've added links to/from the TaharezLook and the WindowsLook list of properties as well as to my message board post; should make it easier to locate this information. I should have done this initially but I thought that peeps would create an executable and use PropertyFinder rather than consulting the Wiki pages.

One day I'll look into adding more information to the Property class, such as the type of data (boolean, float, integer, string), numeric bounds (maxint/minint) or string format (think of a colorect). These should prove useful to toolmakers, although I guess they could always check the effect of setProperty() to determine whether the specified value was valid.
