Hello,

dealing with the animation framework I've found troubles when I try to set some QParallelAnimationGroup and QSequentialAnimationGroup into anothers in a graphicsScene.

All the animations...

Yep, but what I dont understand is how profesional games, with a lot of textures and polygons having way more needs than my modest game works with good performance in a mobile device and it's not...

I was thinking about splitting the image as well. But the large image splitted will cost the same amount of memory. I mean, 100 MB is 100MB if I try one image o 100 images of 1MB.

What you say...

Hi,

I'm asking in this forum because I don't really know what to do. I'm a bit desesperate.

I'm developing a "platform videogame". Each level is a different large QGraphisScene (the bigger is...

Thanks.

On the other hand, 4.7 GraphicsView seems to be way slower than 4.6... I'm developing a game and, when the viewport is moved in order to follow the main character it's slowing down! the...

Here it says

4.7.0. It also introduces OpenGL support for Symbian.

Does it means I could be doing something wrong? or 4.7 does not support openGl for Symbian? So far I was pretty sure it was...

Is OpenGL in Symbian 4.7.3 ^1 not implemented?

I was waiting for this version in order to improve the performance of my QGraphicsView but the eternal...

Hi,

I'm developing a videogame with QGraphicsScene and some QGraphicsItem in my Nokia device. I use to have a big scene (3000x1000 pixels sometimes) with the viewport following the main character...

I agree on that. Any sort of timeline would be highly appreciated.

In my case, is more than needed. I would like to know if I can start rendering the QGraphicsView of my game with openGL or I...

I don't know if it works just executing the sis file from PC, with the mobile plugged.

What I do is to follow next steps to sign it for testing purposes and package the smart installer. After that...

I'm developing a Qt application with 4.6.3

The main widget is a QGrapphicsView and there are around 80 qgraphicspixmap items on the scene. The scene is bigger than the view, one of the...

Maybe I'm having problems with the app icon.

is this enough?

symbian {
ICON = myicon.svg

}

Hello, I've received the next message from qa review process.

Well, I'd like to apologize.

I don't know where I had my head but I tried to do so many things at the same time, and in my hurry I just forget how to read in english...

Right now I realized...

In the end I'm mixing both. A form for the normal-style forms, and QGraphicsProxyWidget if I just want few buttons or not complicated widgets. Everything under stackedwidgets.

Thanks!

QStackedWidget is a very good idea... don't know why I didn't realize :S

Anyway, I don't feel confortable having in memory three or four forms on memory while I'm running complicate scenes in the...

I had it before. But nothing changes.

Now I'm trying to manage everything with the view, using proxyItems. So my form would be a scene. But this uses to be highly unrecommended, isn't?

Switching screens is becoming a pain in the ass.

I want to have a form with some buttons as main screen. But if one is pressed the view will appear on fullscreen.

Setting the view as central...

So I guess the proper way is to let the formulars and the view in memory, just showing-hiding as I want to show them on screen.

But then, if a frame takes more than 40 msecs the program will be stopped.

Note the else is almost never launched. But I need to have that option covered, just in case. The app uses to call the...

If I were you I'd start learning Qt, not trying to understand a medium level example from the beginning.

In my opinion you should try http://doc.qt.nokia.com/qtcreator-snapshot/, step by step.

In the end the problem was the "update". The system decides to draw whenever he wants to, and the update just draws on the screen (forcing the phone to make all the graphical calculations again)...

Hi, I'm having a basic problem with QMainWindow::setCentralWidget

My ui is implemented graphically with Designer, but in some moment I want to hide it and show a QGraphicsView-Scene-Items on top...

If you are new, and QtCreator comes with Qt SDK, the easiest way is to choose QtCreator.

If you are experienced Qt developer and you are used to, for instance, Carbide... you'd prefer to spend...

I just need it in order to improve QGraphicsView performance by using


view->setViewport(new QGLWidget);
