Can I update the wxOgre page?

[grizzley90]

Hey, I want to update the wxOgre page.

I know I might sound lame asking for permission to update a wiki page. But I am unsure how I should do it because in one of the threads, the guy updating the tutorials was criticized for leaving older code on the same page. AND AS THERE CURRENTLY ARE 2 wxOgre pages, one for Ogre v1.0 and one for Ogre v1.2, I am wondering about how I can do this? Should I create a new page for Ogre v1.4 and wxWidgets 2.8? Or should I update the v1.2 page?

Also, I fixed a couple of bugs in the v1.2 page. There is no need for manager.h(it was probably came from somebodies engine), wx/aui/aui.h wasn't included, wxFrameManager ----> wxAuiManager.

[REiNDEeR]

I dont see why not, the wiki has a history system. So if someone wants to take a peek at an older version they can.

[sinbad]

Yeah, go ahead. As long as articles target the current stable version it's fine.

[grizzley90]

Its all done!

http://www.ogre3d.org/wiki/index.php/Wx ... _OGRE_v1.4

Its on a seperate page, I also added a couple of notes for making it work OIS .

[jacmoe]

Thanks for doing this, but why on Earth is it on a separate page?

The wiki should only deal with the current stable Ogre. Which currently means 1.4.

That also means that old Dagon code should be removed everywhere it's to be found.
You can use the history function if you need it.

I will probably delete the page after moving the contents over.

[grizzley90]

That was my question on the first post... just nobody answered it. Everybody simply said I can do it . So I continued with the existing pattern... a new page for each release. Sorry about that.

[jacmoe]

No problems!

[jacmoe]

Blast!
Now we have tree different wxogre pages..

Grizzley90, I assume your page can be just pasted right on top of the main wxOgre page?

I will then get rid of the other two. (1.2 and 1.4 specific versions).

[JorenJoestar7]

What about covering multiple renderwindow under wxWidgets? It will be VERY appreciated by all of us...

Hi!

I'm trying to embed Ogre 1.4.4 in wxWidgets 2.8.5 using this wxOgre and it compiles well but I get an error when it executes the following line:

Code: Select all

mRenderWindow = Ogre::Root::getSingleton().initialise(false);

in void wxOgre::createOgreRenderWindow() which is called in wxOgre constructor. The debugger brings me to this function in window.cpp file:

Code: Select all

bool wxWindowMSW::HandleActivate(int state,
                              bool WXUNUSED(minimized),
                              WXHWND WXUNUSED(activate))
{
    wxActivateEvent event(wxEVT_ACTIVATE,
                          (state == WA_ACTIVE) || (state == WA_CLICKACTIVE),
                          m_windowId);
    event.SetEventObject(this);

    return GetEventHandler()->ProcessEvent(event); //THIS LINE FAILS
}

and in the last line it says *somethink like* this:

Uncaught exception at 0x00000000 in TestwxOgre.exe: 0xC0000005: Memory access violation reading at 0x00000000.

I said 'something like that' because my Visual Studio is in Spanish and I've translated the message as well as I could, so I'm sorry if you don't understand it T_T

I've used the example showed in the wiki with no changes. I'm using:
Windows XP SP2
Visual Studio 2005 Professional Edition with SP1
Ogre 1.4.4
wxWidgets 2.8.5

Can anyone help me, please?

Thank you in advance.
Bye!

did you set the compiler flags? In my #defines, I had to add these:
__GNUWIN32__
__WXMSW__
WXUSINGDLL

or I would get exactly your kind of error - maybe this helps ..

[pumpkin_zch2u]

OGRE, it's wonderful!

Hi,

I am using wxOgre 1.4 with VS2008, wx2.8.7 and the last sdk-ogre aviable, so far wxOgre compile just with warnings (always the same : warning C4245: 'initializing' : conversion from 'int' to 'const Ogre::UTFString::size_type', signed/unsigned mismatch), but when I combine wxOgre with wxFrame (as child) I get the follow errors:

I really need to make run wxOgre, so any advice is welcome!!!

[pengus]

Hi everyone, i've been trying hard to get wxMac and Ogre working together... and failed

Anyone around managed to get a RenderWindow embedded in a Carbon wxWindow ?

Seems like GetHandle() returns some weird values and the rendering appears on the window titlebar, while MacGetTopLevelWindowRef obviously returns the container ref, not the control one...

am totally stuck now after a week of trial and error... any advice is totally welcome

[pengus]

seems like posting on ogre forums brings in some luck

i managed to have some sort of ogre window embedded in wxMac, but it's badly offsetted on top and only resizing the wxWindow a lot it's possible to see something... almost there

if anyone has had this kind of problems and managed to solve it pls pls pls help me

[Kencho]

I had a similar problem at first, but was due to the sizers and how I was structuring everything. Does it work fine if you use, say, a button instead of an wxOgre widget?

[pengus]

Kinda fixed, but now the renderwindow is stuck on bottom/left corner of the main widget and the sizer doesn't automatically resize... apparently ogre renderwindow gets positioned with bottom/left corner at top/left corner of the client region, so i had to shift down the sizer by content height:

Code: Select all

wxRect rect = this->GetClientRect();
wxRect orect = wxOgre->GetRect();
sizer->SetDimension(rect.x, rect.y - orect.height, orect.width, orect.height);

In this way the ogre window is shown, but when resizing is stuck on bottom/left of the sizer... but am almost there

And yes, with buttons and stuff is all fine. Only the renderwindow is misplaced by no reasons apparently

How did you solve it ?

EDIT: removed that awful code and still trying to lock the top/left corner of the renderwindow to the top/left corner of the wxframe... coffee and cigarettes and ready for a all nigher. When i clean the code i add the mac parts to the wiki

[Kencho]

Uhh... can't remember But seems it's not the same problem. Try adding an extra button and see if it overlaps the render window. I remember I had a very bad time trying to figure why they were overlapping, and the problem was there.

[pengus]

ok i got it "almost" working ... meaning the ogre window shows correctly in the wxFrame now !

Code: Select all

sizer = new wxBoxSizer(wxHORIZONTAL);
sizer->Add(wxOgre, 1, wxALIGN_BOTTOM | wxALIGN_LEFT, 1, NULL);

This did the trick, but now each time the window is resized and the OnSize event is called i need to call Layout() to fit the sizer, but as soon as that happens the renderwindow warps on top, again aligned on TOP/LEFT and going up (overwriting the window titlebar)... gah...

EDIT: !!!!!! WORKS !!!! Got Ogre embedded in wx on mac finally ! Now let me clean the code then... can i update the wiki, or should i make a new page for it ?

[sinbad]

So long as you're not losing any information, go ahead and edit that page.

Great job and please update the wiki page -- then it would provide support for all three major operating systems.

It says in the wiki to link against wxCore/base/aui. So I did by using the following:

Code: Select all

OgreMain_d.lib
wxbase28.lib
wxmsw28_core.lib
wxmsw28_aui.lib

Am I missing anything here?

EDIT: fixed by adding

Code: Select all

#define __GNUWIN32__
#define __WXMSW__
#define WXUSINGDLL

BEFORE the call to include "wx/wx.h".

But now the application won't startup, and provides the following error:

I'm trying to implement a FrameListener where the user can interact with wxOgre Frame with the mouse or keyboard, similarly to Ogre's ExampleFrameListener.

Following the wiki page I added the pairs to OIS:

Code: Select all

	wxFrameListener( RenderWindow *renderWindow, Camera *camera, SceneNode* object )
		: mObject(object), mInputManager(0), mMouse(0), mKeyboard(0)
	{
		OIS::ParamList pl;
		size_t windowHnd = 0;
		std::ostringstream windowHndStr;

		renderWindow->getCustomAttribute("WINDOW", &windowHnd);
		windowHndStr << windowHnd;
		pl.insert(std::make_pair(std::string("WINDOW"), windowHndStr.str()));

		pl.insert(std::make_pair(std::string("w32_mouse"), std::string("DISCL_NONEXCLUSIVE")));
		pl.insert(std::make_pair(std::string("w32_mouse"), std::string("DISCL_FOREGROUND")));
		pl.insert(std::make_pair(std::string("w32_keyboard"), std::string("DISCL_NONEXCLUSIVE")));
		pl.insert(std::make_pair(std::string("w32_keyboard"), std::string("DISCL_FOREGROUND")));

		mInputManager = OIS::InputManager::createInputSystem( pl );

		mKeyboard = static_cast<OIS::Keyboard*>(mInputManager->createInputObject( OIS::OISKeyboard, false ));
		
	}

However, the program exits when it tries to create the Keyboard Input Object (last line).
It breaks in the last line of the following code from wx/window:

Code: Select all

bool wxWindowMSW::HandleActivate(int state,
                              bool WXUNUSED(minimized),
                              WXHWND WXUNUSED(activate))
{
    wxActivateEvent event(wxEVT_ACTIVATE,
                          (state == WA_ACTIVE) || (state == WA_CLICKACTIVE),
                          m_windowId);
    event.SetEventObject(this);

    return GetEventHandler()->ProcessEvent(event);
}

Do you know what I am doing wrong?
Is this the way the code snippet was supposed to be used?

thanks in advance

[sprint84]

By the way,

I managed to fix the problem.
It seems that the wiki information is a little bit simplistic, so one can easily pass by some details...

In this part:

Code: Select all

	renderWindow->getCustomAttribute("WINDOW", &windowHnd);
	windowHndStr << windowHnd;
	pl.insert(std::make_pair(std::string("WINDOW"), windowHndStr.str())); 

I was passing the renderwindow to the OIS.
However it is necessary to pass the wxFrame, like this:

Code: Select all

	size_t handle = (size_t)(parent->GetHandle());
	windowHndStr << handle;
	pl.insert(std::make_pair(std::string("WINDOW"), windowHndStr.str()));

where parent is your main frame.

see you
