## Member Function Documentation

void KGradientSelector::setColors | ( | const QColor & | col1,
|  | const QColor & | col2
| ) | `[inline]`

| Sets the two colors which span the gradient. Definition at line 311 of file kselect.h. References QWidget::update().

void KGradientSelector::setFirstColor | ( | const QColor & | col | ) | `[inline]`

| Set each color on its own. Definition at line 319 of file kselect.h. References QWidget::update().

void KGradientSelector::setFirstText | ( | const QString & | t | ) | `[inline]`

void KGradientSelector::drawContents | ( | QPainter * |  | ) | `[protected, virtual]`

Override this function to draw the contents of the control.

The default implementation does nothing.

Draw only within contentsRect().

Reimplemented from KSelector.
