Does anybody successfully embedded Urho3D into Qt?

Hey
does anybody successfully embedded SDL2 / Urho3D into Qt GUI or any other GUI system ?
or knows any examples ?

Hevedy

I have this dl.dropboxusercontent.com/u/280 … DevKit.zip created by ASTER. (changed don’t is the original)

Hey who is ASTER?
any way i compile fine BUT im getting linker erros … allot
have idea why ? same configurations as the examples in urho3d using the latest sources

You’ll need the to add the following Additional Dependencies (Project Properties -> Linker -> Input -> Additional Dependencies):

winmm.lib opengl32.lib imm32.lib

Possibly others as well.

The engine’s built-in UI seems fine but it would be interesting to see this in action just like QtOgre or other implementation…

Urho3D works with an external window handle no problem. The first version of my map editor utilized QT and worked pretty well, but I hated the extra build steps. Currently my external editor is done through wxWidgets and works no problem.

You can view my wxWidgets code here: github.com/thebluefish/Urho3D-M … r/wxUrho3D

As you can see the integration code is very minimal. Qt is actually not that much different, though I remember a few things took a little playing around with to get right. It took me maybe a day or two to get it running in QT relatively well. As long as you can find a barebone template for defining a widget/control/etc… in QT, making an Urho3D widget/control/etc… shouldn’t prove to be difficult.

does it worked well on mac and and linux as in windows ?

umen

wow and in mac its even worst
compilation said :
file compile in x86_64

lipo -info ./Lib/libUrho3D.a input file ./Lib/libUrho3D.a is not a fat file Non-fat file: ./Lib/libUrho3D.a is architecture: x86_64

and when trying to compile the Qt latest 5.2.1 with the Urho3d latest I’m getting sorry of the long output :

I think you’d better use qt4 than qt5. Qt4 is smaller and easy to configuration with cmake.

umen

qt 5 is just fine also i don’t need to configure it with cmake .
i compile the urho3d
then i link it with Qt , but somehow it complain about architecture conflict Although they both compiled the same

aster2013

It is write in Qt

umen

did you did it ?
how did you mange with to work with the Qt and SDL event loops in the same time ?

aster2013

I use a Qt timer to drive engine’s frame, and not use Qt’s event.

    QTimer timer;
    connect(&timer, SIGNAL(timeout()), this, SLOT(OnTimeout()));
    timer.start(30);

void Urho3DEditor::OnTimeout()
{
    if (engine_ && !engine_->IsExiting())
        engine_->RunFrame();
}

umen

Hey thanks ,
does it work without a problem ?
any chance to test your app ?
is it open source ?

aster2013

It is not open source now. I just write it on my local repo.

delrios

Hey @thebluefish, could you send me or upload to git your wxUrho3D code again? Thank you in advance.
