yesterday I hit upon a problem when trying to get the computed text length by calling SVGOMTextElement.getComputedTextLength() - a NullPointerException occured, which, as close scrutiny revealed, had it's origin in the missing SVGContext of the element.
Now, I am somewhat at a loss - I thought an elements context was implicitly set upon creation, no need for me to tamper with it, so I have no idea how to solve the problem. Do I need to set the svgContext manually?
The exception occurs in method breakText(SVGOMTextElement), which is called by afterLoad() - see code below.
Can you give me a pointer how to solve the problem?
Thanks a lot -Urs
Code Excerpt:
private void breakText(SVGOMTextElement text) {
float textLength=text.getComputedTextLength(); //This is where things go
haywire
if textLength<120{...}
else if textLength>120 {...}
...}protected void afterLoad() {
SVGOMTextElement currentNode;
this.graphic=canvas.getSVGDocument();
NodeList textNodes = graphic.getElementsByTagName("text");
int number=textNodes.getLength();
for(int i = 0; i < number; i++) {
currentNode=(SVGOMTextElement) textNodes.item(i);
//Check whether the Text Element is in the right group.
if
(((SVGOMGElement)currentNode.getParentNode().getParentNode().getParentNode()).getAttribute("id").matches("cascade"))
{
addOnClick(currentNode); //adds an EventListener to handle "OnClick" events.
breakText(currentNode); //breaks the text if it is to long
}
}
}
