QTableWidget fails to display column/row content correctly after MainWindow resize.

[d_stranz]

Would you mind trying your self? The entire code for QDragDropWidget is in my previous post. So just place QTableWidget in resizable layout and promote it to QDDW. I'm interested to see of anyone else has this issue.

No, because I am trying to get you to understand that the problem is not in your widget, it is how you are populating the widget with items after you have dropped something. Fine, you are populating a QStringList. You can't build the contents of a QTableWidget by passing in a QStringList, you have to create QTableWidgetItem instances and add each one to the table.

I have asked you to show how you are doing that, because that is very likely where your error lies. Especially since you now say it happens both with and without D&D. The finger isn't pointing at your widget, it is pointing at how you are using the widget.

This is the function that populates the list:

void MainWindow::DropToPlayList(QStringList list, int row)  // row is the location of the row where the files are dropped
{
 if (row < 0)
     row = 0;
 
         for (int c=0;c<list.count();c++)
             {
                 ui.tablePlaylist->insertRow(row+c);
 
                 // create all items for the row
                 uint32_t duration = 0;
                 for (int i=0;i<ui.tablePlaylist->columnCount();i++)
                     {
                      ui.tablePlaylist->setItem(row+c,i, new QTableWidgetItem("")); // create all column items for row
                     }
 
 
                  ui.tablePlaylist->item(row+c,COLUMN_START_TIME)->setText("00:00:00:00");
                  ui.tablePlaylist->item(row+c,COLUMN_DURATION)->setText("duration");
                  ui.tablePlaylist->item(row+c,COLUMN_TITLE)->setText("title");
                  ui.tablePlaylist->item(row+c,COLUMN_LOCATION)->setText("location");
                  ui.tablePlaylist->item(row+c,COLUMN_CATEGORY)->setText("category");
 
            }
 
}

void MainWindow::DropToPlayList(QStringList list, int row)  // row is the location of the row where the files are dropped
{
 if (row < 0)
     row = 0;

         for (int c=0;c<list.count();c++)
             {
                 ui.tablePlaylist->insertRow(row+c);

                 // create all items for the row
                 uint32_t duration = 0;
                 for (int i=0;i<ui.tablePlaylist->columnCount();i++)
                     {
                      ui.tablePlaylist->setItem(row+c,i, new QTableWidgetItem("")); // create all column items for row
                     }
                   

                  ui.tablePlaylist->item(row+c,COLUMN_START_TIME)->setText("00:00:00:00");
                  ui.tablePlaylist->item(row+c,COLUMN_DURATION)->setText("duration");
                  ui.tablePlaylist->item(row+c,COLUMN_TITLE)->setText("title");
                  ui.tablePlaylist->item(row+c,COLUMN_LOCATION)->setText("location");
                  ui.tablePlaylist->item(row+c,COLUMN_CATEGORY)->setText("category");

            }

}

Solution:

QTableWidget::resizeEvent(event);

instead of QWidget::resizeEvent(event);

Ah. Sometimes you don't notice the obvious things until they punch you in the nose. Thanks for posting your solution.
