Member Function Documentation

◆ activate()

void KisToolPan::activate ( const QSet< KoShape * > & shapes )

overridevirtual

This method is called when this tool instance is activated. For any main window there is only one tool active at a time, which then gets all user input. Switching between tools will call deactivate on one and activate on the new tool allowing the tool to flush items (like a selection) when it is not in use.

Parameters

shapes the set of shapes that are selected or suggested for editing by a selected shape for the tool to work on. Not all shapes will be meant for this tool.

See also: deactivate()

Reimplemented from KoToolBase.

Definition at line 30 of file kis_tool_pan.cpp.

    Q_UNUSED(shapes);
 
    m_actionConnections.addConnection(action("movetool-move-up"),
        &QAction::triggered, this, [this] () {
            canvas()->canvasController()->panUp();
        });
 
    m_actionConnections.addConnection(action("movetool-move-down"),
        &QAction::triggered, this, [this] () {
            canvas()->canvasController()->panDown();
        });
 
    m_actionConnections.addConnection(action("movetool-move-left"),
        &QAction::triggered, this, [this] () {
            canvas()->canvasController()->panLeft();
        });
 
    m_actionConnections.addConnection(action("movetool-move-right"),
        &QAction::triggered, this, [this] () {
            canvas()->canvasController()->panRight();
        });
}

◆ beginPrimaryAction()

void KisToolPan::beginPrimaryAction ( KoPointerEvent * event )

overridevirtual

Called by KisToolProxy when a primary action for the tool is started. The event stores the original event that started the stroke. The event is accepted by default. If the tool decides to ignore this particular action (e.g. when the node is not editable), it should call event->ignore(). Then no further continuePrimaryAction() or endPrimaryAction() will be called until the next user action.

Reimplemented from KisTool.

Definition at line 61 of file kis_tool_pan.cpp.

{
    m_lastPosition = event->pos();
    useCursor(KisCursor::closedHandCursor());
}

References KisCursor::closedHandCursor(), m_lastPosition, and KoToolBase::useCursor().

◆ continuePrimaryAction()

void KisToolPan::continuePrimaryAction ( KoPointerEvent * event )

overridevirtual

Called by KisToolProxy when the primary action is in progress of pointer movement. If the tool has ignored the event in beginPrimaryAction(), this method will not be called.

Reimplemented from KisTool.

Definition at line 67 of file kis_tool_pan.cpp.

{
    QPoint pos = event->pos();
    QPoint delta = m_lastPosition - pos;
    canvas()->canvasController()->pan(delta);
    m_lastPosition = pos;
}

References Private::canvas, KoCanvasBase::canvasController(), m_lastPosition, and KoCanvasController::pan().

◆ deactivate()

void KisToolPan::deactivate ( )

overridevirtual

This method is called whenever this tool is no longer the active tool

See also: activate()

Reimplemented from KoToolBase.

Definition at line 55 of file kis_tool_pan.cpp.

{
    m_actionConnections.clear();
    KisTool::deactivate();
}

References KisSignalAutoConnectionsStore::clear(), KisTool::deactivate(), and m_actionConnections.

◆ endPrimaryAction()

void KisToolPan::endPrimaryAction ( KoPointerEvent * event )

overridevirtual

Called by KisToolProxy when the primary action is being finished, that is while mouseRelease or tabletRelease event. If the tool has ignored the event in beginPrimaryAction(), this method will not be called.

Reimplemented from KisTool.

Definition at line 75 of file kis_tool_pan.cpp.

{
    Q_UNUSED(event);
    useCursor(KisCursor::openHandCursor());
}

References KisCursor::openHandCursor(), and KoToolBase::useCursor().

◆ paint()

void KisToolPan::paint	(	QPainter &	painter,
		const KoViewConverter &	converter )

overridevirtual

Called by the canvas to paint any decorations that the tool deems needed. The painter has the top left of the canvas as its origin.

Parameters

painter	used for painting the shape
converter	to convert between internal and view coordinates.

Implements KoToolBase.

Definition at line 81 of file kis_tool_pan.cpp.

{
    Q_UNUSED(painter);
    Q_UNUSED(converter);
}

◆ wantsAutoScroll()

bool KisToolPan::wantsAutoScroll ( ) const

overridevirtual

Return if dragging (moving with the mouse down) to the edge of a canvas should scroll the canvas (default is true).

Returns: if this tool wants mouse events to cause scrolling of canvas.

Reimplemented from KoToolBase.

Definition at line 87 of file kis_tool_pan.cpp.

{
    return false;
}
