QTableWidgetItem Text

[pytro]

hi, i am having some issues, by reading values from tableWidget.

GuiApp.h

//..
private:
    Ui::GuiAppClass ui;	
private slots: 					
    void getTableItemSelected(int,int);

//..
private:
    Ui::GuiAppClass ui;	
private slots: 					
    void getTableItemSelected(int,int);

To copy to clipboard, switch view to plain text mode 

GuiApp.cpp

GuiApp::GuiApp(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
//..
     ui.setupUi(this);
     connect(ui.tableWidget, SIGNAL(cellClicked(int,int)),
	     this, SLOT (getTableItemSelected(int,int)));
}
 
//..
void GuiApp::getTableItemSelected(int row, int col)
{
	QTableWidgetItem *locale = ui.tableWidget->item(row, col);
	QString text = locale->text();
	qDebug("Row %i Col %i Value: %s", row, col, text);
}

GuiApp::GuiApp(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
//..
     ui.setupUi(this);
     connect(ui.tableWidget, SIGNAL(cellClicked(int,int)),
	     this, SLOT (getTableItemSelected(int,int)));
}

//..
void GuiApp::getTableItemSelected(int row, int col)
{
	QTableWidgetItem *locale = ui.tableWidget->item(row, col);
	QString text = locale->text();
	qDebug("Row %i Col %i Value: %s", row, col, text);
}

The table "prints" the values like 3 23 45. But i read this symbols..
Output:
Row 0 Col 0 Value: ♦
Row 0 Col 1 Value: ♥
Row 0 Col 2 Value: ♦

What's the problem?

Thanks in advance.

The problem is that you are trying to print a directly a QString.
You have to get a reference to it's internal buffer first.

QByteArray ascii = text.toAscii();
qDebug("Row %i Col %i Value: %s", row, col, ascii.constData());

QByteArray ascii = text.toAscii();
qDebug("Row %i Col %i Value: %s", row, col, ascii.constData());

One could also include <QtDebug> and use more convenient syntax with built-in support for basic Qt data types, including QString:

#include <QtDebug>
...
qDebug() << locale->text();

#include <QtDebug>
...
qDebug() << locale->text();
