MyGUI::Message::createMessage

Hi,

I am testing MyGUI for my project, all was works fine until i get this problem with Messages.

The problem is that i can't see the message widget but if i press in middel of screen the delegated function works.

I use the default core skin, font, etc.

i can login and change to next gamestate.
i can quit the game if i push in the middel of screen (invisible message widget).

Any idea what is the problem?

Hm, I tried your code - everything works fine. May be you have some large widgets on upper layers that can overlap your message?

Hi,

No, if i make this changes... i got a empty windows that exit when i push in the invisble message widget.

I am compiling the last svn, then i tell you if the problem continues.

Thanks.

Hi,

the problem persist....

if you can figure what is the ploblem plase tell me, i continue trying locate the problem.

thanks.

Try to run only this line in you appMyGUI::MessagePtr pGUIMsg = MyGUI::Message::createMessage(Ogre::String("aaaaa"),Ogre::String("Salir"), true,
MyGUI::Message::IconWarning | MyGUI::Message::Ok); and try to add them to void DemoKeeper::createScene() in DemoKeper.cpp in TestApp in MyGUI sln.

Does other widgets looks normal? Try to create Window.

hi,

Hi,

Well, I change all body code taking as reference baselayout code.

Now all works, but i don't know where was the error.

One comment, if in TestApp main.cpp you make a bucle creating an destroying all, the porogram crahses ¿memory leak?.


unsigned int index = 0;
while(index < 10)
{
demo::DemoKeeper * app = new demo::DemoKeeper();
app->prepare(argc, argv);
app->create();
app->run();
app->destroy();
delete app;
app = 0;

index++;
}

Gotcha, this happens because you don't callmGUI->injectFrameEntered(evt.timeSinceLastFrame);every frame, so all effects related to time (as smooth Message showing) doesn't work.
You also will have troubles with RenderBox, Progress, Edit caret and Tab widget sheets selecting as described here.

Thanks, all solved
