[Qt-interest] Change Svg attribute

[Jason H]

I don't know if is yahoo, or the listserv but sometimes messages are delayed for a while.

The QtSvg should be changed to be read-write. (However Qt has a problem with that)
The QtAnimation API should be extended to take an Xpath as a QProperty for animation purposes.

That's what I meant when I wrote "What you can do is a simple search and replace". :-)

It is still ugly and the performance is terrible. However, for simple colour changes of buttons it is fine. Text changes can be acceptable when the change frequency is not too high. In all other cases some sort of caching mechanism is advisable, since permanent rerendering of a svg file has very quickly a tremendous performance impact.
