Detailed Description

Loading an SVG text is somewhat intricate, so we use a KoSvgTextLoader to keep track of where we are in the tree.

enterNodeSubtree()

void KoSvgTextLoader::enterNodeSubtree

(

)

Set the current node to its first child, entering the subtree.

        nextNode();
    }

leaveNodeSubtree()

void KoSvgTextLoader::leaveNodeSubtree

(

)

Set the current node to its parent, leaving the subtree.

Definition at line 52 of file KoSvgTextLoader.cpp.

{
    d->currentNode = KisForestDetail::parent(d->currentNode);
}

References d, and KisForestDetail::parent().

loadSvg()

bool KoSvgTextLoader::loadSvg	(	const QDomElement &	element,
		SvgLoadingContext &	context,
		bool	root = false )

Create a new text node.

Definition at line 62 of file KoSvgTextLoader.cpp.

        nextNode();
    }
    return d->currentNode->loadSvg(element, context, root);
}

References d, KisForestDetail::isEnd(), and nextNode().

loadSvgText()

bool KoSvgTextLoader::loadSvgText	(	const QDomText &	text,
		SvgLoadingContext &	context )

Loads the textt into the current node.

Definition at line 70 of file KoSvgTextLoader.cpp.

{
    if (KisForestDetail::isEnd(d->currentNode)) {
        nextNode();
    }
    return d->currentNode->loadSvgTextNode(text, context);
}

References d, KisForestDetail::isEnd(), and nextNode().

nextNode()

void KoSvgTextLoader::nextNode

(

)

Switch to next node.

Definition at line 57 of file KoSvgTextLoader.cpp.

{
    d->currentNode = d->shape->d->textData.insert(KisForestDetail::siblingEnd(d->currentNode), KoSvgTextContentElement());
}

References d, and KisForestDetail::siblingEnd().

setStyleInfo()

void KoSvgTextLoader::setStyleInfo

(

KoShape *

s

)

Set the style info from the shape. This is necessary because SVGParser only understands loading the basic style into a KoShape.
