Detailed Description

An axis rect subclass for use in a QCPColorScale.

This is a private class and not part of the public QCustomPlot interface.

It provides the axis rect functionality for the QCPColorScale class.

Definition at line 5356 of file qcustomplot.h.

Constructor & Destructor Documentation

◆ QCPColorScaleAxisRectPrivate()

QCPColorScaleAxisRectPrivate::QCPColorScaleAxisRectPrivate ( QCPColorScale * parentColorScale )

explicit

Creates a new instance, as a child of parentColorScale.

Definition at line 20571 of file qcustomplot.cpp.

Member Function Documentation

◆ axisSelectableChanged()

void QCPColorScaleAxisRectPrivate::axisSelectableChanged ( QCPAxis::SelectableParts selectableParts )

protected

This slot is connected to the selectableChanged signals of the four axes in the constructor. It synchronizes the selectability of the axes.

Definition at line 20701 of file qcustomplot.cpp.

◆ axisSelectionChanged()

void QCPColorScaleAxisRectPrivate::axisSelectionChanged ( QCPAxis::SelectableParts selectedParts )

protected

This slot is connected to the selectionChanged signals of the four axes in the constructor. It synchronizes the selection state of the axes.

Definition at line 20676 of file qcustomplot.cpp.

◆ calculateAutoMargin()

int QCPAxisRect::calculateAutoMargin ( QCP::MarginSide side )

overrideprotectedvirtual

Returns the margin size for this side. It is used if automatic margins is enabled for this side (see setAutoMargins). If a minimum margin was set with setMinimumMargins, the returned value will not be smaller than the specified minimum margin.

The default implementation just returns the respective manual margin (setMargins) or the minimum margin, whichever is larger.

Reimplemented from QCPAxisRect.

Definition at line 5025 of file qcustomplot.cpp.

◆ draw()

void QCPColorScaleAxisRectPrivate::draw ( QCPPainter * painter )

overrideprotectedvirtual

Updates the color gradient image if necessary, by calling updateGradientImage, then draws it. Then the axes are drawn by calling the QCPAxisRect::draw base class implementation.

\seebaseclassmethod

Reimplemented from QCPAxisRect.

Definition at line 20611 of file qcustomplot.cpp.

◆ mouseMoveEvent()

void QCPAxisRect::mouseMoveEvent	(	QMouseEvent *	event,
		const QPointF &	startPos )

overrideprotectedvirtual

Event handler for when the mouse is moved on the axis rect. If range dragging was activated in a preceding mousePressEvent, the range is moved accordingly.

See also: mousePressEvent, mouseReleaseEvent

Reimplemented from QCPAxisRect.

Definition at line 5029 of file qcustomplot.cpp.

◆ mousePressEvent()

void QCPAxisRect::mousePressEvent	(	QMouseEvent *	event,
		const QVariant &	details )

overrideprotectedvirtual

Event handler for when a mouse button is pressed on the axis rect. If the left mouse button is pressed, the range dragging interaction is initialized (the actual range manipulation happens in the mouseMoveEvent).

The mDragging flag is set to true and some anchor points are set that are needed to determine the distance the mouse was dragged in the mouse move/release events later.

See also: mouseMoveEvent, mouseReleaseEvent

Reimplemented from QCPAxisRect.

Definition at line 5028 of file qcustomplot.cpp.

◆ mouseReleaseEvent()

void QCPAxisRect::mouseReleaseEvent	(	QMouseEvent *	event,
		const QPointF &	startPos )

overrideprotectedvirtual

This event gets called when the user releases the mouse button, after this layerable has become the mouse grabber by accepting the preceding mousePressEvent.

The current pixel position of the cursor on the QCustomPlot widget is accessible via event->pos(). The parameter startPos indicates the position where the initial mousePressEvent occurred, that started the mouse interaction.

The default implementation does nothing.

See also: mousePressEvent, mouseMoveEvent, mouseDoubleClickEvent, wheelEvent

Reimplemented from QCPAxisRect.

Definition at line 5030 of file qcustomplot.cpp.

◆ update()

void QCPAxisRect::update ( UpdatePhase phase )

overrideprotectedvirtual

This method is called automatically upon replot and doesn't need to be called by users of QCPAxisRect.

Calls the base class implementation to update the margins (see QCPLayoutElement::update), and finally passes the rect to the inset layout (insetLayout) and calls its QCPInsetLayout::update function.

\seebaseclassmethod

Reimplemented from QCPAxisRect.

Definition at line 5000 of file qcustomplot.cpp.

◆ updateGradientImage()

void QCPColorScaleAxisRectPrivate::updateGradientImage ( )

protected

Uses the current gradient of the parent QCPColorScale (specified in the constructor) to generate a gradient image. This gradient image will be used in the draw method.

Definition at line 20633 of file qcustomplot.cpp.

◆ wheelEvent()

void QCPAxisRect::wheelEvent ( QWheelEvent * event )

overrideprotectedvirtual

Event handler for mouse wheel events. If rangeZoom is Qt::Horizontal, Qt::Vertical or both, the ranges of the axes defined as rangeZoomHorzAxis and rangeZoomVertAxis are scaled. The center of the scaling operation is the current cursor position inside the axis rect. The scaling factor is dependent on the mouse wheel delta (which direction the wheel was rotated) to provide a natural zooming feel. The Strength of the zoom can be controlled via setRangeZoomFactor.

Note, that event->angleDelta() is usually +/-120 for single rotation steps. However, if the mouse wheel is turned rapidly, many steps may bunch up to one event, so the delta may then be multiples of 120. This is taken into account here, by calculating wheelSteps and using it as exponent of the range zoom factor. This takes care of the wheel direction automatically, by inverting the factor, when the wheel step is negative (f^-1 = 1/f).
