C++ (Cpp) SVGTextQuery Examples

Example #1

File: SVGTextContentElement.cpp Project: kodybrown/webkit

float SVGTextContentElement::getSubStringLength(unsigned charnum, unsigned nchars, ExceptionCode& ec)
{
    document().updateLayoutIgnorePendingStylesheets();

    unsigned numberOfChars = getNumberOfChars();
    if (charnum >= numberOfChars) {
        ec = INDEX_SIZE_ERR;
        return 0.0f;
    }

    return SVGTextQuery(renderer()).subStringLength(charnum, nchars);
}

Example #2

File: SVGTextContentElement.cpp Project: junmin-zhu/blink-crosswalk

float SVGTextContentElement::getSubStringLength(unsigned charnum, unsigned nchars, ExceptionState& es)
{
    document().updateLayoutIgnorePendingStylesheets();

    unsigned numberOfChars = getNumberOfChars();
    if (charnum >= numberOfChars) {
        es.throwUninformativeAndGenericDOMException(IndexSizeError);
        return 0.0f;
    }

    if (nchars > numberOfChars - charnum)
        nchars = numberOfChars - charnum;

    return SVGTextQuery(renderer()).subStringLength(charnum, nchars);
}

Example #3

int SVGTextContentElement::getCharNumAtPosition(const FloatPoint& point)
{
    document()->updateLayoutIgnorePendingStylesheets();
    return SVGTextQuery(renderer()).characterNumberAtPosition(point);
}

Example #4

float SVGTextContentElement::getComputedTextLength()
{
    document()->updateLayoutIgnorePendingStylesheets();
    return SVGTextQuery(renderer()).textLength();
}

Example #5

unsigned SVGTextContentElement::getNumberOfChars()
{
    document()->updateLayoutIgnorePendingStylesheets();
    return SVGTextQuery(renderer()).numberOfCharacters();
}
