QTable - paintCell() - how to do with it?

[mp33919]

Hi, hopefully, someone can help me out about the "paintCell()" issues.

All I wanted to do is paint a few selected cells in a relatively large table.

I have done all the seraches in the internet. All I saw were "re-implement" the paintCell(). OK I did it.

1. I created a form - mainForm and drag a table into the form.
2. So, in my project, I have mainform.ui mainform.ui.h and main.cpp
3. So, how can I re-implement paintCell()? I create a class coded in the mainform.ui.h named Table which is inheriated from QTable. And re-write the paintCell() function, sounds right?
4. Then, I pass the compiler. But, I did not pass the linker. The error message is: undefined refernce to mainform:aintCell(... ...) So, what went wrong?

Then, I am thinking, I can pass the linker, how I can invoke this paintCell()? My table was dragged into the form and its the object of the QTable.

I will be really appreciated if anyone can give me a clue.

Best Regards,

Here is the structure of my code:

// filename: mainform.ui.h

class Table::public QTable
{
Q_OBJECT
public:
    void paintCell(QPainter *painter, int row, in col, const QRect &rc, bool selected, const QColorGroup &cg);
};
 
void Table::paintCell( ... ... )
{
... ...
}

class Table::public QTable
{
Q_OBJECT
public:
    void paintCell(QPainter *painter, int row, in col, const QRect &rc, bool selected, const QColorGroup &cg);
};

void Table::paintCell( ... ... )
{
... ...
}
