Qt Qtablewidget Center Display picture __QT5

1. Problem Qtablewidget cannot directly center the picture in item

Qt's Qtablewidget control can be used to display text and pictures

It itself provides a void Qtablewidget::setitem (int row, int column, Qtablewidgetitem *item) method for displaying pictures

Cases:

Ui->tablewidget->setitem (0,1,new Qtablewidgetitem (Qicon (": img/warn.jpg"), ""));

However, Qtablewidget only provides a way to center the text void qlistwidgetitem::settextalignment (int alignment)

Such as:

Ui->tablewidget->item (0, 0)->settextalignment (qt::alignhcenter);

This method only makes the text centered but not the center of the picture

See figure

Leng on the right cannot be centered

2. Use the Qlabel control to center the shape in the Qtablewidget

The void qtablewidget::setcellwidget (int row, int column, Qwidget *widget) method provided by Qtablewidget is used here

The specific code is as follows:

Qlabel *label = new Qlabel ();
Label->setpixmap (Qpixmap (": Img/warn.png"));
Label->setalignment (Qt::alignhcenter);
Ui->tablewidget->setcellwidget (0,1,label);

Effect as shown
