To1ne .. you should really buy some good c++ book or at least do some c++ tutorials about inheritance, polymorphism and encapsulation

So it's fixed. I finally got BetaGUI running (and it feels good).

hi all!
does anybody have a application sample with callbacks used??
i tried to add the betaGUI to my app (create by the wizard), the mouse pointer and the window works, but the button callback no...

thanks!

Same problem here!

In BetaGUI 015 it's like this:

Code: Select all

		mGUI_ExitButton = mGUI_ExitWindow->createButton(Vector4(4,28,100,22), "bgui.button", "Quit", BetaGUI::Callback(this));

Code: Select all

	void onButtonPress(BetaGUI::Button *ref)
	{
		if (ref == mGUI_ExitButton)
			mShutdown = true;
	}

It got it from betajaen short tutorial.

But I don't know how to do it in BetaGUI 020.
I got the some code from GlobalExplorer's example. But I do it like in BetaGUI 015, just one "onButtonPress"-function and check the "*ref" which button is pressed.
Does "BetaGUI::Callback" still exist? Or do I need to use a other method?

GlobalExplorer used a seperate class for his "on_std"-function, but I like to include the function in the "BetaGUIFrameListener"-class. How I do that:

Code: Select all

mGUI_ExitWindow = mGUI->createWindow(100,100,320,164, "betagui", BetaGUI::WFT_MOVE, "SceneNode Inspector", mBetaGUIListener);

What should be the last argument there?
If I leave it this way I get a read/write error on the "on_std"-function.

So who knows how to do it in BetaGUI 2?

The problem with the seperate class is, I can't use variables like "mShutDown" "mGUI_ExitButton"... .

Ok, after many errors works fine:
now my problem is this:

Code: Select all

	mGUI_Menu = mGUI->createWindow(0,0,640,25, "betagui", BetaGUI::WFT_NONE, "MainMenu", this);
	mGUI_Bounding = mGUI_Menu->createButton(2,2, "BoundingBox", (BetaGUI::ButtonMethodPtr) &App::Bounding ); 
	mGUI_Menu->createStaticText(300, 2, "test text");

the window & the menu works fine, but when I add the static text appears this error:

Code: Select all

Run-Time Check Failure #1 - A cast to a smaller data type has caused a loss of data.  If this was intentional, you should mask the source of the cast with the appropriate bitmask.  For example:  

	char c = (i & 0xFF);

Changing the code in this way will not affect the quality of the resulting optimized code.

at this line:

Code: Select all

text->setParameter("char_height", Ogre::StringConverter::toString(mGUI->mStyle[mStyle]->mFontSize));

thanks!

So, you use BetaGUI 2. How did you solve my problem?

Post by **betajaen** » Tue May 22, 2007 9:21 am

You guys do realise that the BetaGUI2 code I posted only covers the events with buttons? TextInputs and the other widgets prototyped there don't work.

I admire your effects trying to get it working, but you should consider using the Bullet Version of BetaGUI or even KungFooMasta's QuickGUI, until at least I actually finish the code.

and how log does approximately take?

i'm really dying to see BetaGui3

Post by **betajaen** » Tue May 22, 2007 9:40 am

A while, I'm nearly at the end of the academic year so lots of things to do that, and there are a bunch of people in the NxOgre forum who want me for other things.

To1ne · Post by **To1ne** » Tue May 22, 2007 10:42 am

Thx for the TIP mate, good point!!!

I need TextInput's too, so I'll take the Bullet (hopefully it's not much editing to my working 15version)

EDIT:
It doesn't work:

Code: Select all

error C2259: 'BetaGUIFrameListener' : cannot instantiate abstract class

"BetaGUIFrameListener" is declared like this:

Code: Select all

class BetaGUIFrameListener : public ExampleFrameListener, BetaGUI::BetaGUIListener

And it seems to be "BetaGUIListener" is abstract. (I had the same problem with BetaGUI 2).

So this is the "BetaGUIListener"-class:

Code: Select all

	class BetaGUIListener 
    {
		public:
			virtual void onButtonPress(Button*, unsigned char) = 0;
    };

Why is it abstract?
And how do I fix this problem?

My code is basic the same as betajaen sample code on page 2 of this topic.

Post by **betajaen** » Tue May 22, 2007 11:06 am

It's an extension of the original BetaGUI, so the small tutorial and sample code on the BetaGUI wiki page is applicable.

ghiboz · Post by **ghiboz** » Tue May 22, 2007 11:10 am

me too...
with the 2 the callback worked fine, now, i can't reach to manage the callbacks...

bye!

To1ne · Post by **To1ne** » Tue May 22, 2007 11:14 am

@ ghiboz
Don't get how you did it in BetaGUI 2. Because these are the errors I got in BetaGUI2 too. While BetaGUI 15 worked fine.

@ betajaen
On the Wiki-page is a "typo":

Code: Select all

class myCallbackOrMainClass : public public BetaGUI::BetaGUIListener {

2 times "public"??

Code: Select all

mGUI = new BetaGUI::GUI("??","font",16);

What should be the first argument?
Are there extra resources needed?

Post by **betajaen** » Tue May 22, 2007 11:22 am

It's a typo, and the second is the name of the Overlay.

ghiboz · Post by **ghiboz** » Tue May 22, 2007 11:22 am

www.ghiboz.com/tmp/bguires.zip
inside a font and all the materials that aren't in the default package:
with this you can do this:

Code: Select all

mGUI = new BetaGUI::GUI("testgui", "MgOpen", 16, mWindow);
mPointer = mGUI->createMousePointer(Vector2(50, 50), "bgui.pointer");
BetaGUI::Window* window = mGUI->createWindow(Vector4(1, 1, 300, 100), "bgui.window" ,BetaGUI::WFT_RESIZE_AND_MOVE, "window caption" );

@ ghiboz
So do you have a solution for our problem?

ghiboz · Post by **ghiboz** » Tue May 22, 2007 12:38 pm

To1ne wrote:@ ghiboz

no, compile, but give this error:

Code: Select all

BetaGUI::Button* bBoxes = window->createButton(Vector4(20, 10, 50, 20), "bgui.button", "button", BetaGUI::Callback( mListen ) );

the mListen is :

Code: Select all

Listen* mListen;
...
class Listen : public BetaGUI::BetaGUIListener
{
	Listen(void) {};
	~Listen(void) {};
	public:
		void onButtonPress(BetaGUI::Button *ref) 
		{
			static Ogre::uint boundtype = 0;
			boundtype += 1;	
		}
};

but the problem is that i can't initialize mListener, 'cause is abstract, so when the betaGUI uses the callback, gives error.

				break;
		}
	}
...


//where I use:
	mGUI = new BetaGUI::GUI(mWindow);
	mPointer = mGUI->createMousePointer("bgui.pointer",50,50); 

	
	BetaGUI::Window* mGUI_Menu;
	BetaGUI::Button *mGUI_Shadows;
	BetaGUI::Button *mGUI_Bounding;
    BetaGUI::Style* mBetaGUIStyle = mGUI->createStyle("betagui");
    mBetaGUIStyle->mWindow_Background = "bgui.window";
    mBetaGUIStyle->mFontFace = "MgOpen";
    mBetaGUIStyle->addStyle("button", "background: bgui.button; height: 20; text-align: center; font-size: 14; decal-size: 10;");
    mBetaGUIStyle->addStyle("titlebar", "background: bgui.titlebar; height: 20; font-size: 15;");
    mBetaGUIStyle->addStyle("textinput", "background: bgui.textinput; height: 20; font-size: 12; decal-size: 5;"); 
	
	mGUI_Menu = mGUI->createWindow(0,0,640,25, "betagui", BetaGUI::WFT_NONE, "MainMenu", this);
	mGUI_Bounding = mGUI_Menu->createButton(2,2, "BoundingBox", (BetaGUI::ButtonMethodPtr) &gApp::Bounding );

and works the window, the button!

bye!

Don't get it anymore:
I have a working solution with BetaGUI 1.5 . But I've looked up, and "BetaGUI::BetaGUIListener" seems to be abstract too. But I can compile en run. And BetaGUI 1.6 doesn't compile, because it's an abstract class.
So what should I do to fix it?

@ betajaen
Are there a lot of differences between version 15 en 16?
And what are they?

@ ghiboz
A little tip:

Code: Select all

mPointer = mGUI->createMousePointer("bgui.pointer",50,50);

Change the "50,50" to "32,32". It should look better.

@ nebukadnezzar
I found a real good online tutorial here about classes, friends, inheritance and polymorphism. I'll look in to it (when I have some time). I admit I'm not a genius in C++-programming.

ghiboz · Post by **ghiboz** » Tue May 22, 2007 2:40 pm

thanks, with the 1.5 works!
thanks for the mouse tip....

To1ne · Post by **To1ne** » Tue May 22, 2007 8:43 pm

Ok, I give up on 016.

@ betajaen
In your demo-video, how did you make the static button in the top left-corner to close the program?

Epimetheus · Post by **Epimetheus** » Wed May 30, 2007 12:51 am

I'm trying to get BetaGUI 015 working in my SpaceNav experiment program but when i try to compile it (having only added it to my code::blocks project (linux), included it from my app class and created the BetaGUI::GUI object) I get alot of ambiguous definitons of uint :O anyone else with this problem who maybe could tell me how to solve it.

Candidates are unsigned int uint in types.h and Ogre::uint

Post by **betajaen** » Wed May 30, 2007 12:53 am

Weird, Sounds like a namespace problem. You could bypass it an just do a search and replace for "uint" with "unsigned int".
