Hi,
I have the following structure:
<flowText xml:space="preserve"
xmlns="http://xml.apache.org/batik/ext";>
<flowRegion>
<rect x="109" width="365" y="172" height="100"/>
</flowRegion>
<flowDiv>
<flowPara>My first flow text</flowPara>
</flowDiv>
</flowText>
This starts fine. But I then want to change the X,Y co-ordinates so I I
have this bit of code, where element points to the 'rect' object in
flowRegion tag:
UpdateManager um = this.getCanvas().getUpdateManager();
if (um != null && um.isRunning() &&
um.getUpdateRunnableQueue().getThread() != Thread.currentThread()) {
um.getUpdateRunnableQueue().invokeLater(new Runnable() {
public void run() {
System.out.println("SVGFlowText::propertyChange :
update manager available");
element.setAttributeNS(getNamespace(), SVGConstants.SVG_X_ATTRIBUTE,
val)
}
});
} else {
System.out.println("SVGFlowText::propertyChange : no update
manager available");
element.setAttributeNS(getNamespace(),
SVGConstants.SVG_X_ATTRIBUTE, val)
}
The actual values which show up in the SVG print out have changed but the
canvas has not updated. I know I could use a group element and transform
that but I don't see why this way does not work either.
Is there anything in the way the canvas updates which means that it would
not see the 'rect' attribute change to get it to redraw the flowPara
object?
Any clues and help gratefully received.
Tom
