SOLVED: Table Widget crashes Application

Qatto

Hello,
I have been struggling with a table widget that crashes the application when I call any function that removes a row. The purpose of the table is to display users' photos and names with a checkbox which when checked removes them from the table. Please look through the code below and assist me. ROW is a global array that determines if a row or user is to be shown. FIRST_NAME, LAST_NAME and PHOTO are _QVarLengthArray_s that are accessed by the respective variables.

@void MainWindow::display_table()
{
//Reset Table....................................................
ui->tableWidget->setRowCount(0);
ui->tableWidget->setColumnCount(0);

//Number of Rows Needed............................
int rows = 0;
for(int a=0;a<10; a++)
{
if(ROW[a]==1){rows++;}
}
if(rows==0){
return;
}

QString *accessFirst = FIRST_NAME.data();
QString *accessLast = LAST_NAME.data();
QString *accessPhoto = PHOTO.data();

//Table Properties............................
ui->tableWidget->setRowCount(rows);
ui->tableWidget->setColumnCount(3);
ui->tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers);
ui->tableWidget->setColumnWidth(0, 20);
ui->tableWidget->setColumnWidth(1, 50);
ui->tableWidget->setColumnWidth(2, 150);

for(int r=0; r<10; r++)
{
    if(ROW[r]==1)
    {
        ui->tableWidget->setRowHeight(r, 50);

//CheckBox............................
QWidget* wdgt = new QWidget;
QHBoxLayout *layout = new QHBoxLayout(wdgt);

        if(r==0) layout->addWidget(&CheckBox0);
        else if(r==1) layout->addWidget(&CheckBox1);
        else if(r==2) layout->addWidget(&CheckBox2);
        else if(r==3) layout->addWidget(&CheckBox3);
        else if(r==4) layout->addWidget(&CheckBox4);
        else if(r==5) layout->addWidget(&CheckBox5);
        else if(r==6) layout->addWidget(&CheckBox6);
        else if(r==7) layout->addWidget(&CheckBox7);
        else if(r==8) layout->addWidget(&CheckBox8);
        else layout->addWidget(&CheckBox9);

        layout->setMargin(0);
        layout->setAlignment( Qt::AlignCenter );
        wdgt->setLayout(layout);
        ui->tableWidget->setCellWidget(r, 0, wdgt);

//Photo............................
QLabel *imageLabel = new QLabel;
QPixmap *image = new QPixmap(accessPhoto[r]);
QPixmap Image = image;
imageLabel->setPixmap(Image.scaledToHeight(50));
QWidget wdg = new QWidget;
QHBoxLayout *Layout = new QHBoxLayout(wdg);
Layout->addWidget(imageLabel);
Layout->setMargin(0);
Layout->setAlignment( Qt::AlignCenter );
wdg->setLayout(Layout);
ui->tableWidget->setCellWidget(r, 1, wdg);

//Names............................
QTableWidgetItem *names = new QTableWidgetItem(accessFirst[r]+" "+accessLast[r]);
names->setTextAlignment(Qt::AlignCenter);
ui->tableWidget->setItem(r, 2, names);
}
}
}@

After some checkboxes are checked, a function remove_checked() is called by a button
@void MainWindow::remove_checked()
{
if(CheckBox0.isChecked()==true) ROW[0]=0;
if(CheckBox1.isChecked()==true) ROW[1]=0;
if(CheckBox2.isChecked()==true) ROW[2]=0;
if(CheckBox3.isChecked()==true) ROW[3]=0;
if(CheckBox4.isChecked()==true) ROW[4]=0;
if(CheckBox5.isChecked()==true) ROW[5]=0;
if(CheckBox6.isChecked()==true) ROW[6]=0;
if(CheckBox7.isChecked()==true) ROW[7]=0;
if(CheckBox8.isChecked()==true) ROW[8]=0;
if(CheckBox9.isChecked()==true) ROW[9]=0;

//Refresh Table.....................................
display_table();
}@

The application crashes when a row is removed e.g. ui->tableWidget->removeRow(0);

What does your debugger tell you?

Qatto

Everything builds fine, just the crashing after removing a row

andre

I asked about your debugger, not your compiler

thats the compiler then not the debugger ;)

show us at least some code of the call were it crashes. The setup of the table seems ok so far on the first glance.

I guess I just have to opt for a tableWiget created at runtime
