add text to qtablewidget

[rashmi]

hey all,

i have application with QTableWidget of 3X4. i need to load image along with corresponding name of the icon.

i have the following code to display text

QFont fnt;
    fnt.setPointSize(30);
    fnt.setFamily("Arial");
 
 for (int r = 0; r < t.rowCount(); ++r)
     {
        for (int c = 0; c < t.columnCount(); ++c)
        {
            QTableWidgetItem* item = new QTableWidgetItem;
            item->setBackgroundColor(Qt::black);
            item->setIcon(QIcon(QString(":/images/img%1.png").arg(r * t.columnCount() + c)));
 
            item->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled);
 
            // writting icon name
 
            item->setTextColor(Qt::white);
            item->setFont(fnt);
            item->setText("help");
            item->setTextAlignment(Qt::AlignBottom|Qt::AlignLeading);
 
            t.setItem(r, c, item);
        }
     }

QFont fnt;
    fnt.setPointSize(30);
    fnt.setFamily("Arial");

 for (int r = 0; r < t.rowCount(); ++r)
     {
        for (int c = 0; c < t.columnCount(); ++c)
        {
            QTableWidgetItem* item = new QTableWidgetItem;
            item->setBackgroundColor(Qt::black);
            item->setIcon(QIcon(QString(":/images/img%1.png").arg(r * t.columnCount() + c)));

            item->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled);

            // writting icon name

            item->setTextColor(Qt::white);
            item->setFont(fnt);
            item->setText("help");
            item->setTextAlignment(Qt::AlignBottom|Qt::AlignLeading);

            t.setItem(r, c, item);
        }
     }

To copy to clipboard, switch view to plain text mode 

following code displays help in all the cell. now my question is how would i display different text in each cell based on icon i load.

hope i am clear.

[wysota]

Pass different strings to QTableWidgetItem::setText() instead of passing "help" each time.

[rashmi]

i hope you did not get what i meant.
i will explain i want to display help in cell1 ,file in cell2 , save in cell3 and exit in cell4 (this completes one row) .similarly i want to display different text in 2 more rows.

hope i am clear now.

[wysota]

So what's the problem? What is keeping you from doing that?

[rashmi]

it would be helpful if you tel me your suggestion clearly. i really cant understand what are you trying to say.

item->setText("help");

since this is inside for loop it prints help in all the cells of 3X4 table. but i want different text in each cell how do i do it.

[wysota]

So why did you place it inside that loop in the first place?

[rashmi]

i can place that only inside loop if i place it outside i get error as it is not in scope.

i hope you give me some solution for this.

hi,

if u want autonumber u can use the following code,

QFont fnt;
    fnt.setPointSize(30);
    fnt.setFamily("Arial");
 
 for (int r = 0; r < t.rowCount(); ++r)
     {
        for (int c = 0; c < t.columnCount(); ++c)
        {
            QTableWidgetItem* item = new QTableWidgetItem;
            item->setBackgroundColor(Qt::black);
            item->setIcon(QIcon(QString(":/images/img%1.png").arg(r * t.columnCount() + c)));
 
            item->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled);
 
            // writting icon name
 
            item->setTextColor(Qt::white);
            item->setFont(fnt);
 
            item->setText(QString::number(r *c));  
            item->setTextAlignment(Qt::AlignBottom|Qt::AlignLeading);
 
            t.setItem(r, c, item);
        }
     }

QFont fnt;
    fnt.setPointSize(30);
    fnt.setFamily("Arial");

 for (int r = 0; r < t.rowCount(); ++r)
     {
        for (int c = 0; c < t.columnCount(); ++c)
        {
            QTableWidgetItem* item = new QTableWidgetItem;
            item->setBackgroundColor(Qt::black);
            item->setIcon(QIcon(QString(":/images/img%1.png").arg(r * t.columnCount() + c)));

            item->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled);

            // writting icon name

            item->setTextColor(Qt::white);
            item->setFont(fnt);

            item->setText(QString::number(r *c));  
            item->setTextAlignment(Qt::AlignBottom|Qt::AlignLeading);

            t.setItem(r, c, item);
        }
     }

To copy to clipboard, switch view to plain text mode 

if u want to give a specific name to each item.
then u can use a stringlist to store the name.
and inside the loop u can use that in setText.
ex : setText(myImageName.at(i)); something like tat.

hope it helps

i can place that only inside loop if i place it outside i get error as it is not in scope.

So ask the table widget for the item again outside the inner loop and set the text there.
