just check QPixmap::isNull()
Pixmap is not null... Image was saved for the half and I read it... Pixmap successfully loaded but draws only first part of the image while the next one is grey...

I try to load image with next function. static inline QPixmap loadPixmap( const QString & path ) { QPixmap p; QFile imgFile( path ); if( imgFile.open( QIODevice::ReadOnly ) ) { p.loadFromData( imgFile.readAll() ); imgFile.close(); qDebug() << "is pixmap null" << p.isNull(); } else qDebug() << "Couldn't open image file for reading" << path << "error" << imgFile.errorString() << imgFile.error(); return p; } On Windows I receive errors like that file is blocked by another process. It's normal. If returned pixmap is null i'm trying to reload failed image after some timeout. But on Linux file always opens on reading even if it is incomplete yet... It's bad. I receive artifacts in view such as loaded on the half images... And I can't check it. How can I be sure that image loaded completely? -- Best Regards, Igor Mironchik. _______________________________________________ Interest mailing list Interest@qt-project.org <mailto:Interest@qt-project.org> http://lists.qt-project.org/mailman/listinfo/interest
