Can we please move the adjustment for alpha
void ListBox::startDragAndDrop (const MouseEvent& e, DragAndDropData::Ptr dragData)
{
//...
dragImage.multiplyAllAlphas (0.6f);
to the end of ListBox::createSnapshotOfSelectedRows():
const Image ListBox::createSnapshotOfSelectedRows (int& imageX, int& imageY)
{
//...
snapshot.multiplyAllAlhas (0.6f);
return snapshot;
}
I’m overriding createSnapshotOfSelectedRows() and creating my own ARGB Image and I’d like full control over the alpha channel.
