 Posted: Fri Feb 04, 2011 8:48 am Post subject: Qtd Painter Error |
 |
|
I set up some test code to see if I built Qtd properly. Whenever I mouse over the quit button I get the following error:
| Code: | QPaintDevice: Cannot destroy paint device that is being painted
object.Error: Access Violation |
And here is the code that I am using: | Code: | import qt.gui.QApplication;
import qt.gui.QMainWindow;
import qt.gui.QWidget;
import qt.gui.QLabel;
import qt.gui.QPushButton;
import qt.gui.QVBoxLayout;
int main(string[] args)
{
scope App = new QApplication(args);
scope label = new QLabel(tr("Hello, World!"));
scope quit = new QPushButton(tr("&Quit"));
scope widget = new QWidget;
widget.setLayout(new QVBoxLayout);
widget.layout.addWidget(label);
widget.layout.addWidget(quit);
scope window = new QMainWindow;
window.setWindowTitle(tr("Hello"));
window.setCentralWidget(widget);
QObject.connect(quit, "clicked", window, "close");
window.show();
return App.exec();
} |

Looks like some paint message is being sent to a destroyed windows.
Shouldn't you call the app's quit slot instead? |

| I always do close in case I want to do something before the window is destroyed but I doesn't matter as the error triggers when the tip of the mouse hovers over the button, not when it is clicked. |

I see this in my app too, but only on Windows.
I think it might have something to do with the Layouts. Simple examples without layouts work fine but using a layout like your code or my code seems to crash. |

FYI, my app seems to work if I use "-style cde" on the command line, so there are no mouse over effects.
Kinda sucks, but at least we've got something to work with. |

| It works but definitely not ideal. |

Yeah. I'm afraid I had to give up on QtD at this point. It worked so well on Linux, but even with the -style hack, it still had some random crashes on Windows as I used the app.
I ultimately decided to write a small dll in C++ that handles the GUI, and the main app is in D. They pass messages over a handful of simple C style functions. |

| How do you compile the c++ code? I have been unable to get it to work. |

i got this to work on windows 7 by compiling with -mstackrealign option e.g.
cmake -G"MinGW Makefiles" -DCMAKE_CXX_FLAGS=-m32 -fpermissive -mstackrealign" ../ |
