Detailed Description

A layout element displaying a text.

The text may be specified with setText, the formatting can be controlled with setFont, setTextColor, and setTextFlags.

A text element can be added as follows:

Constructor & Destructor Documentation

◆ QCPTextElement() [1/5]

QCPTextElement::QCPTextElement ( QCustomPlot * parentPlot)
explicit

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ QCPTextElement() [2/5]

QCPTextElement::QCPTextElement ( QCustomPlot * parentPlot,
const QString & text )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Creates a new QCPTextElement instance and sets default values.

The initial text is set to text.

◆ QCPTextElement() [3/5]

QCPTextElement::QCPTextElement ( QCustomPlot * parentPlot,
const QString & text,
double pointSize )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Creates a new QCPTextElement instance and sets default values.

The initial text is set to text with pointSize.

◆ QCPTextElement() [4/5]

QCPTextElement::QCPTextElement ( QCustomPlot * parentPlot,
const QString & text,
const QString & fontFamily,
double pointSize )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Creates a new QCPTextElement instance and sets default values.

The initial text is set to text with pointSize and the specified fontFamily.

◆ QCPTextElement() [5/5]

QCPTextElement::QCPTextElement ( QCustomPlot * parentPlot,
const QString & text,
const QFont & font )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Creates a new QCPTextElement instance and sets default values.

The initial text is set to text with the specified font.

Member Function Documentation

◆ applyDefaultAntialiasingHint()

void QCPTextElement::applyDefaultAntialiasingHint ( QCPPainter * painter) const
protectedvirtual

Reimplemented from QCPLayoutElement.

◆ clicked

void QCPTextElement::clicked ( QMouseEvent * event)
signal

This signal is emitted when the text element is clicked.

See also
doubleClicked, selectTest

◆ deselectEvent()

void QCPTextElement::deselectEvent ( bool * selectionStateChanged)
protectedvirtual

Reimplemented from QCPLayerable.

◆ doubleClicked

void QCPTextElement::doubleClicked ( QMouseEvent * event)
signal

This signal is emitted when the text element is double clicked.

See also
clicked, selectTest

◆ draw()

void QCPTextElement::draw ( QCPPainter * painter)
protectedvirtual

Reimplemented from QCPLayoutElement.

◆ maximumOuterSizeHint()

QSize QCPTextElement::maximumOuterSizeHint ( ) const
protectedvirtual

Returns the suggested maximum size this layout element (the outerRect) may be expanded to, if no manual maximum size is set.

if a maximum size (setMaximumSize) was not set manually, parent layouts use the returned size (usually indirectly through QCPLayout::getFinalMaximumOuterSize) to determine the maximum allowed size of this layout element.

A manual maximum size is considered set if it is smaller than Qt's QWIDGETSIZE_MAX.

The default implementation simply returns QWIDGETSIZE_MAX for both width and height, implying no suggested maximum size. Reimplementations may use their detailed knowledge about the layout element's content to provide size hints.

Reimplemented from QCPLayoutElement.

◆ minimumOuterSizeHint()

QSize QCPTextElement::minimumOuterSizeHint ( ) const
protectedvirtual

Returns the suggested minimum size this layout element (the outerRect) may be compressed to, if no manual minimum size is set.

if a minimum size (setMinimumSize) was not set manually, parent layouts use the returned size (usually indirectly through QCPLayout::getFinalMinimumOuterSize) to determine the minimum allowed size of this layout element.

A manual minimum size is considered set if it is non-zero.

The default implementation simply returns the sum of the horizontal margins for the width and the sum of the vertical margins for the height. Reimplementations may use their detailed knowledge about the layout element's content to provide size hints.

Reimplemented from QCPLayoutElement.

◆ mouseDoubleClickEvent()

void QCPTextElement::mouseDoubleClickEvent ( QMouseEvent * event,
const QVariant & details )
virtual

Emits the doubleClicked signal.

\seebaseclassmethod

Reimplemented from QCPLayerable.

◆ mousePressEvent()

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

Accepts the mouse event in order to emit the according click signal in the mouseReleaseEvent.

\seebaseclassmethod

Reimplemented from QCPLayerable.

◆ mouseReleaseEvent()

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

Emits the clicked signal if the cursor hasn't moved by more than a few pixels since the mousePressEvent.

\seebaseclassmethod

Reimplemented from QCPLayerable.

◆ selectEvent()

void QCPTextElement::selectEvent ( QMouseEvent * event,
bool additive,
const QVariant & details,
bool * selectionStateChanged )
protectedvirtual

Reimplemented from QCPLayerable.

◆ selectionChanged

void QCPTextElement::selectionChanged ( bool selected)
signal

This signal is emitted when the selection state has changed to selected, either by user interaction or by a direct call to setSelected.

See also
setSelected, setSelectable

◆ selectTest()

double QCPTextElement::selectTest ( const QPointF & pos,
bool onlySelectable,
QVariant * details = nullptr ) const
virtual

Returns 0.99*selectionTolerance (see QCustomPlot::setSelectionTolerance) when pos is within the bounding box of the text element's text. Note that this bounding box is updated in the draw call.

If pos is outside the text's bounding box or if onlySelectable is true and this text element is not selectable (setSelectable), returns -1.

\seebaseclassmethod

Reimplemented from QCPLayoutElement.

◆ setFont()

void QCPTextElement::setFont ( const QFont & font)

Sets the font of the text.

See also
setTextColor, setSelectedFont

◆ setSelectable()

void QCPTextElement::setSelectable ( bool selectable)

Sets whether the user may select this text element.

Note that even when selectable is set to false, the selection state may be changed programmatically via setSelected.

◆ setSelected()

void QCPTextElement::setSelected ( bool selected)

Sets the selection state of this text element to selected. If the selection has changed, selectionChanged is emitted.

Note that this function can change the selection state independently of the current setSelectable state.

◆ setSelectedFont()

void QCPTextElement::setSelectedFont ( const QFont & font)

Sets the font of the text that will be used if the text element is selected (setSelected).

See also
setFont

◆ setSelectedTextColor()

void QCPTextElement::setSelectedTextColor ( const QColor & color)

Sets the color of the text that will be used if the text element is selected (setSelected).

See also
setTextColor

◆ setText()

void QCPTextElement::setText ( const QString & text)

Sets the text that will be displayed to text. Multiple lines can be created by insertion of "\n".

See also
setFont, setTextColor, setTextFlags

◆ setTextColor()

void QCPTextElement::setTextColor ( const QColor & color)

Sets the color of the text.

See also
setFont, setSelectedTextColor

◆ setTextFlags()

void QCPTextElement::setTextFlags ( int flags)

Sets options for text alignment and wrapping behaviour. flags is a bitwise OR-combination of Qt::AlignmentFlag and Qt::TextFlag enums.

Possible enums are:

  • Qt::AlignLeft
  • Qt::AlignRight
  • Qt::AlignHCenter
  • Qt::AlignJustify
  • Qt::AlignTop
  • Qt::AlignBottom
  • Qt::AlignVCenter
  • Qt::AlignCenter
  • Qt::TextDontClip
  • Qt::TextSingleLine
  • Qt::TextExpandTabs
  • Qt::TextShowMnemonic
  • Qt::TextWordWrap
  • Qt::TextIncludeTrailingSpaces
