Member Enumeration Documentation

◆ DisplayMode

enum KexiGradientWidget::DisplayMode

Modes for displaying the gradient.

Enumerator
NoGradient 

No gradient at all. Will behave just like a TQWidget.

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.

◆ GradientType

enum KexiGradientWidget::GradientType

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

Definition at line 61 of file kexigradientwidget.h.

◆ eventFilter()

bool KexiGradientWidget::eventFilter ( TQObject * object,
TQEvent * event )
protectedvirtual

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.
