Initialization of QPalette.

ankit thakar

Hello team,

I was going through demo code of QPalette. Below is the code.
QColor color = QColorDialog::getColor(QColor(m_label->text()),this,"Select color",QColorDialog::ShowAlphaChannel);
if(color.isValid())
{
QPalette palette = m_label->palette();
palette.setColor(QPalette::Window,color);
m_label->setPalette(palette);
m_label->setText(color.name());
}

Now instead of initializing QPalette like this QPalette palette = m_label->palette();
if I do like this,
QPalette palette;
palette.setColor(QPalette::Window,color);
m_label->setPalette(palette);
m_label->setText(color.name());

What is the difference in both initialization?

The first one grabs the current palette from m_label , sets the color to color and sets the edited palette to the label again.
Everything else will be the same as m_labels palette.

The second one creates a new palette with default parameters and color color (No additional brush, shadow or anything else)
