Detailed Description

Provides an SVG with borders.

When using SVG images for a background of an object that may change its aspect ratio, such as a dialog, simply scaling a single image may not be enough.

FrameSvg allows SVGs to provide several elements for borders as well as a central element, each of which are scaled individually. These elements should be named

center - the central element, which will be scaled in both directions
top - the top border; the height is fixed, but it will be scaled horizontally to the same width as center
bottom - the bottom border; scaled in the same way as top
left - the left border; the width is fixed, but it will be scaled vertically to the same height as center
right - the right border; scaled in the same way as left
topleft - fixed size; must be the same height as top and the same width as left
bottomleft, topright, bottomright - similar to topleft

center must exist, but all the others are optional. topleft and topright will be ignored if top does not exist, and similarly for bottomleft and bottomright.

Returns: the size of the frame

Definition at line 196 of file framesvg.cpp.

void Plasma::FrameSvg::getFixedMargins	(	qreal &	left,
		qreal &	top,
		qreal &	right,
		qreal &	bottom
	)		const

Convenience method that extracts the size of the four margins in the four output parameters Compared to getMargins(), this doesn't depend whether the margins are enabled or not.

Parameters

left	left margin size
top	top margin size
right	right margin size
bottom	bottom margin size

Definition at line 270 of file framesvg.cpp.

void Plasma::FrameSvg::getMargins	(	qreal &	left,
		qreal &	top,
		qreal &	right,
		qreal &	bottom
	)		const

Convenience method that extracts the size of the four margins in the four output parameters The disabled margins will be 0.

If you don't care about the margins being on or off, use getFixedMargins()

Parameters

left	left margin size
top	top margin size
right	right margin size
bottom	bottom margin size

Definition at line 257 of file framesvg.cpp.

bool Plasma::FrameSvg::hasElementPrefix ( const QString & prefix ) const

Returns: true if the svg has the necessary elements with the given prefix to draw a frame

Parameters

prefix the given prefix we want to check if drawable

Definition at line 141 of file framesvg.cpp.

bool Plasma::FrameSvg::hasElementPrefix ( Plasma::Types::Location location ) const

This is an overloaded method provided for convenience equivalent to hasElementPrefix("north"), hasElementPrefix("south") hasElementPrefix("west") and hasElementPrefix("east")

Returns: true if the svg has the necessary elements with the given prefix to draw a frame.

Parameters

location the given prefix we want to check if drawable

Definition at line 152 of file framesvg.cpp.

bool Plasma::FrameSvg::isRepaintBlocked ( ) const

Returns: true if we are in a transaction of many changes at once and we don't want to rebuild the generated graphics for each change yet

Since: 5.31

Definition at line 870 of file framesvg.cpp.

qreal Plasma::FrameSvg::marginSize ( const Plasma::Types::MarginEdge edge ) const

Returns the margin size given the margin edge we want If the given margin is disabled, it will return 0.

If you don't care about the margin being on or off, use fixedMarginSize()

Parameters

edge	the margin edge we want, top, bottom, left or right

Returns: the margin size

Definition at line 205 of file framesvg.cpp.

QRegion Plasma::FrameSvg::mask ( ) const

Returns a mask that tightly contains the fully opaque areas of the svg.

Returns: a region of opaque areas

Definition at line 299 of file framesvg.cpp.

void Plasma::FrameSvg::paintFrame	(	QPainter *	painter,
		const QRectF &	target,
		const QRectF &	source = `QRectF()`
	)

Paints the loaded SVG with the elements that represents the border.

Parameters

painter	the QPainter to use
target	the target rectangle on the paint device
source	the portion rectangle of the source image

Definition at line 350 of file framesvg.cpp.

void Plasma::FrameSvg::paintFrame	(	QPainter *	painter,
		const QPointF &	pos = `QPointF(0, 0)`
	)

Paints the loaded SVG with the elements that represents the border This is an overloaded member provided for convenience.

Parameters

painter	the QPainter to use
pos	where to paint the svg

Definition at line 362 of file framesvg.cpp.

QString Plasma::FrameSvg::prefix ( )

Returns the prefix for SVG elements of the FrameSvg.

Returns: the prefix

Definition at line 168 of file framesvg.cpp.

void Plasma::FrameSvg::resizeFrame ( const QSizeF & size )

Resize the frame maintaining the same border size.

Parameters

size	the new size of the frame

Definition at line 173 of file framesvg.cpp.

void Plasma::FrameSvg::setCacheAllRenderedFrames ( bool cache )

Sets whether saving all the rendered prefixes in a cache or not.

Parameters

cache if use the cache or not

Definition at line 317 of file framesvg.cpp.

void Plasma::FrameSvg::setElementPrefix ( Plasma::Types::Location location )

Sets the prefix (.

See also: setElementPrefix) to 'north', 'south', 'west' and 'east' when the location is TopEdge, BottomEdge, LeftEdge and RightEdge, respectively. Clears the prefix in other cases.

The prefix must exist in the SVG document, which means that this can only be called successfully after setImagePath is called.

Parameters

location location in the UI this frame will be drawn

Definition at line 99 of file framesvg.cpp.

void Plasma::FrameSvg::setElementPrefix ( const QString & prefix )

Sets the prefix for the SVG elements to be used for painting.

For example, if prefix is 'active', then instead of using the 'top' element of the SVG file to paint the top border, 'active-top' element will be used. The same goes for other SVG elements.

If the elements with prefixes are not present, the default ones are used. (for the sake of speed, the test is present only for the 'center' element)

Setting the prefix manually resets the location to Floating.

The prefix must exist in the SVG document, which means that this can only be called successfully after setImagePath is called.

Parameters

prefix prefix for the SVG elements that make up the frame

Definition at line 122 of file framesvg.cpp.

void Plasma::FrameSvg::setEnabledBorders ( const EnabledBorders borders )

Sets what borders should be painted.

Parameters

flags borders we want to paint

Definition at line 81 of file framesvg.cpp.

void Plasma::FrameSvg::setImagePath ( const QString & path )

overridevirtual

Loads a new Svg.

Parameters

imagePath the new file

Reimplemented from Plasma::Svg.

Definition at line 66 of file framesvg.cpp.

void Plasma::FrameSvg::setRepaintBlocked ( bool blocked )

If we will do several changes at once in the frame properties, such as prefix, enabled borders and size, in order to not regenerate the graphics for each change, set this property to true, and set it to false again after applying all the changes needed.

Note that any change will not be visible in the painted frame while this property is set to true.

Since: 5.31

Definition at line 875 of file framesvg.cpp.
