[RESOLVED] Problems chaning background color of QTableWidgetItem

[Sarol]

Good Day Everyone,

I just upgraded to QT 4 this week, and still learning some of the features.

Currently my problem is changing the background color of a QTalbeWidgetItem

Here is what I am doing:

dataTable->itemat( row , col ) -> setBackground ( QBrush( Qt::cyan) ) ;

(where dataTable is a QTableWidget)

The good news is a cell does appear in cyan, however it is the wrong cell, and it's always the cell at 0 , 0 no matter what row , col I use.

If somebody could help me figure out what I'm doing wrong it would be greatly appreciated.

Let me know if more info is needed on this problem.

Thank you,

Sarol

I figured out how to do what I needed but still not sure why the above method does not work. Here is I changed:

Original Code:
dataTable->itemat( row , col ) -> setBackground ( QBrush( Qt::cyan) ) ;

New Code:
dataTable->item( row , col ) ->setData( Qt::BackgroundRole , QBrush( Qt::cyan ) ) ;

And now its all working...

The error must have been elsewhere since this is the implementation of setBackground:

inline void setBackground(const QBrush &brush) { setData(Qt::BackgroundRole, brush); }

inline void setBackground(const QBrush &brush) { setData(Qt::BackgroundRole, brush); }

Your row and col must have had wrong values.

well after looking at my original code I found what I was doing wrong.

I was doing:
dataTable->itemat( row , col ) -> setBackground ( QBrush( Qt::cyan) ) ;

When I should have been doing:
dataTable->item( row , col ) -> setBackground ( QBrush( Qt::cyan) ) ;

Now on to other issues.
