Хочу сделать перенос из списка в таблицу. Строка из списка должна записываться в первый столбец. Захват из QListWidget происходит, но почему-то не переносится в QTableWidget. Пробовал переносить в ворд, всё нормально. QListWidgetWithDrop.cpp | Код |
#include "qlistwidgetwithdrop.h"
#include <QtGui>
QListWidgetWithDrop::QListWidgetWithDrop(QWidget *parent) :
QListWidget(parent)
{
setDragEnabled(true);
}
//-----------------------------------------------------------------------------------------------
void QListWidgetWithDrop::mousePressEvent(QMouseEvent *event)
{
if (event->button() == Qt::LeftButton)
startPos = event->pos();
QListWidget::mousePressEvent(event);
}
//-----------------------------------------------------------------------------------------------
void QListWidgetWithDrop::mouseMoveEvent(QMouseEvent *event)
{
if (event->buttons() & Qt::LeftButton) {
int distance = (event->pos() - startPos).manhattanLength();
if (distance >= QApplication::startDragDistance())
{
performDrag();
}
}
QListWidget::mouseMoveEvent(event);
}
//-----------------------------------------------------------------------------------------------
void QListWidgetWithDrop::performDrag()
{
QListWidgetItem *item = currentItem();
if (item) {
QMimeData *mimeData = new QMimeData;
mimeData->setText(item->text());
QDrag *drag = new QDrag(this);
drag->setMimeData(mimeData);
if (drag->exec(Qt::MoveAction) == Qt::MoveAction)
delete item;
}
}
