Qt Svg Module

[onurozcelik]

Hi guys

I want to use QGraphicsSvgItems when modelling a visual object. So I inherit from QGraphicsSvgItem and reimplement paint.
I want my visual object to have different behavior when IO interaction like mouse click occurs.

For example lets assume I have a svg graphic that contains a red rectangle. When a mouse click occurs I want my rectangle to have flashing effect.(maybe animation or something like that)

1- Can it be achieved in one svg file or multiple svg files.
2- If it can be only achievd with multiple svg files will it be a poor choice because of loading svg files needs to access to disk again and again.

Can someone help me about these issues?

Can what be achieved with one svg file? So far I don't see the use for multiple files here - you have an svg item and you wish to do something with it.

yes I have svg items I wish to do something with them when a user interaction occurs. For instance when I click on svg item i want to change its background color. Is it possible with one svg file? How?

Looks like you need to identify two sub-drawings in your SVG file and then use QGraphicsSvgItem::setElementId() to select the one you wish to have the item draw.

Paint the background and then render the svg.

I created sub-drawings and then use setElementId to select one it is working perfectly on static svg drawings. But when I use svg animation elements in svg drawing and then I use setElementId function to select animated drawing the animation does not work, the animation is working if it do not use setElementId

Interesting idea it will give a try
