Unsolved Restrict drag and drop to current widget
-
Hello,
In my application there is a QPlainTextEdit and custom widgets that accept drops. My problem is that when I drag a part of the text to one of these widgets, the original text is deleted in QPlainTextEdit, while my goal is to leave the text unchanged.
I tried to change that by overriding dragEnterEvent to set a CopyAction as the default drop action (instead of a MoveAction) :
void ScriptTextEdit::dragEnterEvent(QDragEnterEvent *event){ QPlainTextEdit::dragEnterEvent(event); event->setDropAction(Qt::CopyAction); return; }
However, just by watching what happens in the other widget :
void otherWidget::dragEnterEvent(QDragEnterEvent *event) { qDebug() << event->dropAction(); }
I can see that the dropAction is once again a MoveAction, so it doesn't work.
Hence my questions :
- Is it possible to prevent the drag and drop from "leaving" a widget without re-implementing the dropEvent method from every widget in the app ?
- If so, how can I achieve this ?
