Member Enumeration Documentation

enum KexiGradientWidget::DisplayMode
 

Modes for displaying the gradient.

Enumerator:
NoGradient  No gradient at all. Will behave just like a QWidget.
FadedGradient  Gradient will be faded with the widgets background.
SimpleGradient  Gradient will replace the usual widget background.

Definition at line 51 of file kexigradientwidget.h.

enum KexiGradientWidget::GradientType
 

Gradient type specification. See GradientType for more details (part of the KDEFX library)

Member Function Documentation

DisplayMode KexiGradientWidget::displayMode  )  const [inline]
 

Get the current displaymode.

Definition at line 96 of file kexigradientwidget.h.

bool KexiGradientWidget::eventFilter QObject *  object,
QEvent *  event
[protected, virtual]
 

Manage list of child-widgets.

Add the new child-widget to our list of known widgets.

... and install 'this' as the child's event-filter.

Remove the child-widget from the list of known widgets.

Manage custombackground-list.

p_currentChild will be == 0L, when the user sets it's palette manually. In this case, it has to be added to the customBackground-list.

Check if the widget whose PaletteChange-event we handle isn't the widget we set the background in rebuildCache().

Add the new child to the list of widgets, we don't set the background ourselves if it isn't in the list.

If the palette is now the default-palette again, remove it from the "don't set background in rebuildCache()"-list and rebuild the cache, so it again will get the gradient background.

QColor KexiGradientWidget::gradientColor1  )  const [inline]
 

Returns:
the color #1 used for the gradient.

Definition at line 142 of file kexigradientwidget.h.

QColor KexiGradientWidget::gradientColor2  )  const [inline]
 

Returns:
the color #2 used for the gradient.

Definition at line 145 of file kexigradientwidget.h.

GradientType KexiGradientWidget::gradientType  )  const [inline]
 

Get the current gradient-type.

Definition at line 112 of file kexigradientwidget.h.

void KexiGradientWidget::paintEvent QPaintEvent *  e  )  [protected, virtual]
 

Rebuild the background-pixmap if necessary.

Draw the widget as usual

Definition at line 205 of file kexigradientwidget.cpp.

virtual void KexiGradientWidget::polish  )  [inline, virtual, slot]
 

The cache needs to be rebuild once the widget is set up completely.

Definition at line 236 of file kexigradientwidget.h.

void KexiGradientWidget::setBlendOpacity double  opacity  )  [inline]
 

Sets the opacity of the gradient when fading with background. opacity has to be between 0.0 and 1.0.

Definition at line 151 of file kexigradientwidget.h.

void KexiGradientWidget::setDisplayMode DisplayMode  mode  )  [inline]
 

Set the displaymode mode. The widget will be updated automatically.

Definition at line 87 of file kexigradientwidget.h.

void KexiGradientWidget::setGradientColor1 const QColor &  color  )  [inline]
 

Set color #1 for the gradient-effect. color is the new color.

Definition at line 118 of file kexigradientwidget.h.

void KexiGradientWidget::setGradientColor2 const QColor &  color  )  [inline]
 

Set color #2 for the gradient-effect. color is the new color.

Definition at line 125 of file kexigradientwidget.h.

void KexiGradientWidget::setGradientColors const QColor &  color1,
const QColor &  color2
[inline]
