Grid Problem

Hi All

I m working on QT4.2 on my Intel MAC ,

I had made a grid of 16x16 i.e. 16 rows and 16 columns on a widget with the help of Qt Programing.
And also used QPushbutton.
and
On click Event of the button Grid fills with the colour say RED.

But what I want is this when I clicks on the button the whole grid fills with the colour but slowly ,

that is It should be viewed that how whole grid is filled

i.e first it completes first row then second and so on...

for this I also used sleep and QTimerEvent but both doesnt works.

If anybody understands my Problem Then Pls help.

Thanx

I am not sure whether this works properly but here is what came to my mind. I assume Grid is a widget since you didn't furnish these details.

Code:

---

class Grid : public QWidget
{
Q_OBJECT
        public:
                Grid(QWidget *par) : QWidget(par)
                {
                        curRow = 0;
                        curCol = 0;
                        timer = new QTimer(this);
                        timer.setSingleShot(true);
                        connect(timer,SIGNAL(timeout()),this,SLOT(fillGrid()));
                 }
 
        public slots:
                // This slot connected to push button's clicked signal
                void fillGrids()
                {
                        timer.start(100);
                }
 
                void fillGrid()
                {
                        grid[curRow][curCol].fill(); // This is just pseudo code
                        curRow++,curCol++;
                        if(curRow >= MAX_ROWS || curCol >= MAX_COLS)
                                return;
                        timer.start(100);
                }
...
}

I may be wrong since I cant test this at the moment. Please do correct me if anything is wrong.

Thanx for the help

But with the use of QTimer, It works the same as it works before. On a single click of the button It fills the whole grid with the colour but with the difference , that after clicking on the button it wont displays anything until a mouse points over the widget.
