row colors

Im using a reimplemented QAbstractTableModel and a QTableView. What Im doing is getting information about how the model/view should look from an xml file (background color, foreground color etc.)
This is from my view...

Code:

---

void WTrackTableView::setup(QDomNode node)
{
	// Position
	if (!WWidget::selectNode(node, "Pos").isNull())
    {
		QString pos = WWidget::selectNodeQString(node, "Pos");
		int x = pos.left(pos.find(",")).toInt();
		int y = pos.mid(pos.find(",")+1).toInt();
		move(x,y);
	}
 
    // Size
	if (!WWidget::selectNode(node, "Size").isNull())
    {
		QString size = WWidget::selectNodeQString(node, "Size");
		int x = size.left(size.find(",")).toInt();
		int y = size.mid(size.find(",")+1).toInt();
		setFixedSize(x,y);
    }
 
    // Background color
	QColor bgc(255,255,255);
    if (!WWidget::selectNode(node, "BgColor").isNull())
    {
        bgc.setNamedColor(WWidget::selectNodeQString(node, "BgColor"));
    }
	m_pTable->setBackgroundColor(bgc);
 
    // Foreground color
	QColor fgc(0,0,0);
    if (!WWidget::selectNode(node, "FgColor").isNull())
    {
        fgc.setNamedColor(WWidget::selectNodeQString(node, "FgColor"));
    }
	m_pTable->setForegroundColor(bgc);
     /*
    // Row colors
    if (!WWidget::selectNode(node, "BgColorRowEven").isNull())
    {
        QColor r1;
        r1.setNamedColor(WWidget::selectNodeQString(node, "BgColorRowEven"));
        QColor r2;
        r2.setNamedColor(WWidget::selectNodeQString(node, "BgColorRowUneven"));
		setAlternatingRowColors ( true );
		m_pTable->setRowColor(r1, r2);
    }
 
    // BPM confidence colors
    if (!WWidget::selectNode(node, "BgColorBpmNoConfirm").isNull())
    {
        QColor c1;
        c1.setNamedColor(WWidget::selectNodeQString(node, "BgColorBpmNoConfirm"));
        QColor c2;
        c2.setNamedColor(WWidget::selectNodeQString(node, "BgColorBpmConfirm"));
		WTrackTableItem::setBpmBgColors(WSkinColor::getCorrectColor(c1),
			WSkinColor::getCorrectColor(c2));
    }
*/
}

Here are the functions in the model:

Code:

---

void WTrackTableModel::setBackgroundColor(QColor bgColor)
{
	backgroundColor = bgColor;
}
void WTrackTableModel::setForegroundColor(QColor fgColor)
{
	foregroundColor = fgColor;
}
void WTrackTableModel::setRowColor(QColor evenColor, QColor unevenColor)
{
	rowEvenColor = evenColor;
	rowUnevenColor = unevenColor;
}
void WTrackTableModel::setBpmColor(QColor confirmColor, QColor noConfirmColor)
{
	bpmNoConfirmColor = noConfirmColor;
	bpmConfirmColor = confirmColor;
}

---

And Finally, the data function:

Code:

---

QVariant WTrackTableModel :: data(const QModelIndex &index, int role) const
{
	TrackInfoObject *m_pTrackInfo = m_pTrackCollection->getTrack(index.row()+1);
	if (!index.isValid())
		return QVariant();
 
    if (index.row() >= m_pTrackCollection->getSize())
        return QVariant();
 
	if (role == Qt::BackgroundRole)
	{
		return backgroundColor;
	}
	if (role == Qt::ForegroundRole )
	{
		return foregroundColor;
	}
	else if (role == Qt::DisplayRole )
	{
		switch(index.column())
		{
		case 0: return m_pTrackInfo->getScoreStr();
		case 1: return m_pTrackInfo->getTitle();
		case 2: return m_pTrackInfo->getArtist();
		case 3: return m_pTrackInfo->getType();
		case 4: return m_pTrackInfo->getDurationStr();
		case 5: return m_pTrackInfo->getBitrateStr();
		case 6: return m_pTrackInfo->getBpmStr();
		case 7: return m_pTrackInfo->getComment();
		}
	}
 
    else
        return QVariant();
}

Now my problem is that the foreground color does not come out as I want it to. It compiles fine, but when I go to look at my model/view at first glance it appears to be an empty table. but when I click around, the Items in the model show up fine when they're highlighted. What could be causing this?

Also, I'm having some trouble figuring out how to set up alternating colors in my model. as you can see setAlternatingRowColors(true) is used but i dont feel that it is working. What do I need to do to these functions to get them to set the row coloring?

Thanks!

Perhaps "m_pTable->setForegroundColor(bgc)"?

Take a look at QAbstractItemView::alternatingRowColors docs. QPalette::Base and QPalette::AlternateBase are used for alternating row colors. Now, providing other color for Qt::BackgroundRole overwrites alternating row colors.

Thanks for the help on the foregroundcolor issue! Sometimes I guess you just need another pair of eyes :p.

However, I did have a question regarding the QPalette::Base and AlternateBase. How would you set it up so that when they are needed, they return the correct values? For example:

Code:

---

QVariant WTrackTableModel :: data(const QModelIndex &index, int role) const
{
	TrackInfoObject *m_pTrackInfo = m_pTrackCollection->getTrack(index.row()+1);
	if (!index.isValid())
		return QVariant();
 
    if (index.row() >= m_pTrackCollection->getSize())
        return QVariant();
 
	/*if (role == Qt::BackgroundRole)
	{
		return backgroundColor;
	}*/
	if(role == QPalette::Base)
		return backgroundColor;
 
	if (role == Qt::ForegroundRole )
	{
		return foregroundColor;
	}
	else if (role == Qt::DisplayRole )
	{
		switch(index.column())
		{
		case 0: return m_pTrackInfo->getScoreStr();
		case 1: return m_pTrackInfo->getTitle();
		case 2: return m_pTrackInfo->getArtist();
		case 3: return m_pTrackInfo->getType();
		case 4: return m_pTrackInfo->getDurationStr();
		case 5: return m_pTrackInfo->getBitrateStr();
		case 6: return m_pTrackInfo->getBpmStr();
		case 7: return m_pTrackInfo->getComment();
		}
	}
 
    else
        return QVariant();
}

"if(role == QPalette::Base)" does not work nor does "if(role == Qt::Base)". How then should I fix this for Base and AlternatingBase?

Palette is a property of widget, see QWidget::palette for more details.

Code:

---

QPalette palette = view->palette();
palette.setColor(QPalette::Base, Qt::red);
palette.setColor(QPalette::AltgernateBase, Qt::green);
view->setPalette(palette);
