qCheckbox back ground color

[ggrinder]

The QPalette::Base role is responsible for the color of the box.

The following snippet would set it do blue.

QCheckBox cb ( "A CheckBox" );
 
QPalette p = cb.palette( );
QColor blue( 0, 0, 255 );
p.setColor( QPalette::Active, QPalette::Base, blue );
cb.setPalette( p );

QCheckBox cb ( "A CheckBox" );

QPalette p = cb.palette( );
QColor blue( 0, 0, 255 );
p.setColor( QPalette::Active, QPalette::Base, blue );
cb.setPalette( p );
