QClipboard/QMimeData problem with transparent images
-
Hello,
i want to display an image that is stored within the clipboard using a QGraphicsScene object. If i use the the imageData() method i get an image that has lost its alpha channel. The normally transparent background is displayed as black. I am using the following code:
@QPixmap image(mimeData->imageData().value<QPixmap>());
if (!image.isNull()) {
QGraphicsPixmapItem * imageItem = m_gfxScene.addPixmap(image);
ui->m_gfxView->show();
}@Is there a way to avoid this behavior?
Another problem occured as i tried to get access to the "plain" clipboard data. If i try to call mimeData->data() i get a segmentation fault (SIGSEGV):
@ QString mf = mimeData->formats().at(0); // contains an image format string
QByteArray arr = mimeData->data(mf); // Segmentation fault
// or
QByteArray arr(mimeData->data(mf)); // Segmentation fault@I use the Qt SDK 1.1 RC and built the code using MinGW 4.4 (Qt 4.7.3 for Desktop).
Thanks in advance!
