Constructor & Destructor Documentation

Digikam::AbstractWidgetDelegateOverlay::AbstractWidgetDelegateOverlay

(

QObject *

parent

)

This class provides functionality for using a widget in an overlay.

You must reimplement at least createWidget to return your widget. Per default it will be shown when the cursor enters an index and hidden when left. Reimplement slotEntered() and mouseMove() for more fine grained control.

Member Function Documentation

virtual QWidget* Digikam::AbstractWidgetDelegateOverlay::createWidget

(

)

[protected, pure virtual]

Create your widget here.

When creating the object, pass parentWidget() as parent widget. Ownership of the object is passed. It will be deleted in setActive(false).

Implemented in Digikam::HoverButtonDelegateOverlay, and Digikam::ImageRatingOverlay.

bool Digikam::AbstractWidgetDelegateOverlay::eventFilter	(	QObject *	obj,
		QEvent *	event
	)			[protected]

Definition at line 197 of file imagedelegateoverlay.cpp.

void Digikam::AbstractWidgetDelegateOverlay::hide

(

)

[protected, virtual]

Called when the widget shall be hidden (mouse cursor left index, viewport, uninstalled etc.

). Default implementation hide()s m_widget.

Reimplemented in Digikam::ImageRatingOverlay.

Definition at line 159 of file imagedelegateoverlay.cpp.

QWidget * Digikam::AbstractWidgetDelegateOverlay::parentWidget

(

)

const [protected]

Returns the widget to be used as parent for your widget created in createWidget().

Definition at line 165 of file imagedelegateoverlay.cpp.

void Digikam::AbstractWidgetDelegateOverlay::setActive

(

bool

active

)

[virtual]

If active is true, this will call createWidget(), initialize the widget for use, and setup connections for the virtual slots.

If active is false, this will delete the widget and disconnect all signal from model and view to this object (!)

Reimplemented from Digikam::ImageDelegateOverlay.

Reimplemented in Digikam::HoverButtonDelegateOverlay, Digikam::ImageRatingOverlay, Digikam::ImageRotateLeftOverlay, Digikam::ImageRotateRightOverlay, and Digikam::ImageSelectionOverlay.

Definition at line 120 of file imagedelegateoverlay.cpp.

void Digikam::AbstractWidgetDelegateOverlay::slotEntered

(

const QModelIndex &

index

)

[protected, virtual, slot]

Default implementation shows or hides the widget if index is valid or not valid.

Reimplemented in Digikam::HoverButtonDelegateOverlay, and Digikam::ImageRatingOverlay.

Definition at line 175 of file imagedelegateoverlay.cpp.

void Digikam::AbstractWidgetDelegateOverlay::slotLayoutChanged

(

)

[protected, virtual, slot]

Definition at line 192 of file imagedelegateoverlay.cpp.

void Digikam::AbstractWidgetDelegateOverlay::slotReset

(

)

[protected, virtual, slot]

Default implementations of these three slots call hide().

Reimplemented in Digikam::HoverButtonDelegateOverlay.

Definition at line 170 of file imagedelegateoverlay.cpp.

void Digikam::AbstractWidgetDelegateOverlay::slotRowsRemoved	(	const QModelIndex &	parent,
		int	start,
		int	end
	)			[protected, virtual, slot]

Definition at line 187 of file imagedelegateoverlay.cpp.

void Digikam::AbstractWidgetDelegateOverlay::slotViewportEntered

(

)

[protected, virtual, slot]

Definition at line 182 of file imagedelegateoverlay.cpp.
