i am writing a qt4 gui application which has the following:
-a main window with a widget which will hold:
-an ogre instance (that is not important now, it is left empty)
-a dockwidget with 2 buttons: one will cause the rendering of an image and show a dialog window, the other button just shows/hides the dialog window
-a dialog window to show the image (i have read somewhere that i should just put a label and use setpixmap to assign a pixmat to it)
here are my sources: http://pastebin.com/HXkT3Jut
here are the ui files: http://pastebin.com/0TKKDziv
the segfault happens at this line:
raytracerRenderDialog->renderedImageContainer->setPixmap(QPixmap::fromImage(renderedImage));
a few notes:
-i know that the way i implemented on_actionShow_render_triggered and on_actionRender_triggered is not the correct way, it is just temporary to see how it works
-the application flow is like this: press render button -> generate raw image pixels -> show generated image in dialog
