Member Function Documentation

QPainter::CompositionMode QgsTextBufferSettings::blendMode ( ) const

Returns the blending mode used for drawing the buffer.

See also: setBlendMode()

Definition at line 167 of file qgstextrenderer.cpp.

QColor QgsTextBufferSettings::color ( ) const

Returns the color of the buffer.

See also: setColor()

Definition at line 127 of file qgstextrenderer.cpp.

bool QgsTextBufferSettings::enabled ( ) const

Returns whether the buffer is enabled.

See also: setEnabled()

Definition at line 87 of file qgstextrenderer.cpp.

bool QgsTextBufferSettings::fillBufferInterior ( ) const

Returns whether the interior of the buffer will be filled in.

If false, only the stroke of the text will be drawn as the buffer. The effect of this setting is only visible for semi-transparent text.

See also: setFillBufferInterior()

Definition at line 137 of file qgstextrenderer.cpp.

Qt::PenJoinStyle QgsTextBufferSettings::joinStyle ( ) const

Returns the buffer join style.

See also: setJoinStyle

Definition at line 157 of file qgstextrenderer.cpp.

double QgsTextBufferSettings::opacity ( ) const

Returns the buffer opacity.

The opacity is a double value between 0 (fully transparent) and 1 (totally opaque).

See also: setOpacity()

Definition at line 147 of file qgstextrenderer.cpp.

QgsTextBufferSettings & QgsTextBufferSettings::operator= ( const QgsTextBufferSettings & other )

Copy constructor.

Parameters

other source QgsTextBufferSettings

Definition at line 76 of file qgstextrenderer.cpp.

QgsPaintEffect * QgsTextBufferSettings::paintEffect ( ) const

Returns the current paint effect for the buffer.

Returns: paint effect

See also: setPaintEffect()

Definition at line 177 of file qgstextrenderer.cpp.

void QgsTextBufferSettings::readFromLayer ( QgsVectorLayer * layer )

Reads settings from a layer's custom properties (for QGIS 2.x projects).

Parameters

layer source vector layer

Definition at line 188 of file qgstextrenderer.cpp.

void QgsTextBufferSettings::readXml ( const QDomElement & elem )

Read settings from a DOM element.

See also: writeXml()

Definition at line 259 of file qgstextrenderer.cpp.

void QgsTextBufferSettings::setBlendMode ( QPainter::CompositionMode mode )

Sets the blending mode used for drawing the buffer.

Parameters

mode	blending mode

See also: blendMode()

Definition at line 172 of file qgstextrenderer.cpp.

void QgsTextBufferSettings::setColor ( const QColor & color )

Sets the color for the buffer.

Parameters

color buffer color

See also: color()

Definition at line 132 of file qgstextrenderer.cpp.

void QgsTextBufferSettings::setEnabled ( bool enabled )

Sets whether the text buffer will be drawn.

Parameters

enabled set to true to draw buffer

See also: enabled()

Definition at line 92 of file qgstextrenderer.cpp.

void QgsTextBufferSettings::setFillBufferInterior ( bool fill )

Sets whether the interior of the buffer will be filled in.

Parameters

fill	set to false to drawn only the stroke of the text as the buffer, or true to also shade the area inside the text. The effect of this setting is only visible for semi-transparent text.
