Color ComboBox

[wysota]

I don't modify the model I didn't say my code was better than yours, I have only shown how to make my color combobox display colors in a different way. Many ways may lead to the same result, there is no point in discussing the differences.

but any way you have to get colors from model
ok, agree with this "Many ways may lead to the same result".

Hi,

I tried the spirit's idea. It works fine for the menu but the selected option does not display the background color.
How can I put the color in the background of the actual index?

Thank you very much!

When the index changes I need to set the base with the color of the current index:

QColor color = qvariant_cast<QColor>(model()->index(index, 0).data(Qt::BackgroundColorRole));
 
QPalette pal = palette();
pal.setColor(QPalette::Base, color);
setPalette(pal);

QColor color = qvariant_cast<QColor>(model()->index(index, 0).data(Qt::BackgroundColorRole));

QPalette pal = palette();
pal.setColor(QPalette::Base, color);
setPalette(pal);

To copy to clipboard, switch view to plain text mode 

This works very well, I have the correct color in the right place... but, the highlight mess it up. I don't need the highlight since I'm working with colors.
Is there a way to simple remove the highlight?

I had tried this:

pal.setColor(QPalette::Highlight, Qt::transparent);

pal.setColor(QPalette::Highlight, Qt::transparent);

To copy to clipboard, switch view to plain text mode 

but it's not transparent, it's white.

I did a workaround. The idea was make the highlight with the same color of the item.

Connect the highlighted signal from QComboBox:

ComboBoxColor( QWidget *parent = 0 ) : QComboBox( parent )
{
    connect( this, SIGNAL(highlighted(int)), this, SLOT(slotHighlight(int)) );
}

ComboBoxColor( QWidget *parent = 0 ) : QComboBox( parent )
{
    connect( this, SIGNAL(highlighted(int)), this, SLOT(slotHighlight(int)) );
}

To copy to clipboard, switch view to plain text mode 

The slot will set the correct color for the current item:

void ComboBoxColor::slotHighlight(int index)
{
    const QStringList colorNames = QColor::colorNames();
    QColor color(colorNames.at(index));
 
    QPalette palette = this->palette();
    palette.setColor(QPalette::Highlight, color);
    setPalette(palette);
}

void ComboBoxColor::slotHighlight(int index)
{
    const QStringList colorNames = QColor::colorNames();
    QColor color(colorNames.at(index));

    QPalette palette = this->palette();
    palette.setColor(QPalette::Highlight, color);
    setPalette(palette);
}
