Issue in setting the canvas size( Mouse click not active in whole
area of the applet)
Hi Batik experts,
I am using Batik in visualizing my application images.
I have a functionality of highlighting/unhighlighting objects ,which
is when I click on a particular object(image) , it gets highlighted
and if I click anywhere else on the frame(applet) it should get
unhighlighted.
The issue is when an object is highlighted then only between a fix
area only the unhighlighting is working.
Even when i try to track the mouse click action then also it is not
able to sense the click event beside that particular area..
Is it the problem of canvas size?
How can I enable my mouse click event all over the applet?
Thanks & regards,
Shekhar

Hi Jonathan,
Thanks for reply.
Our case is little different.We are not using actual SVG files, we
have jsp pages with embedded svg tags in that.
We have a frame in our application which has these images and this
ungighlighting only works only within some specific area of that
frame.
I will try to implement your suggestion in some way into my framewoek
and get back to you.
Thanks again.

Corrections...
use a <rect> instead of a <g> for the glasspane and ensure it covers the
entire svg/viewBox
sorry for the confusion

Hi Shekhar,
If I understand correctly, you have 1 (or more) elements on the canvas and
you would like to highlight the clicked one and unhighlight when the
background is clicked. The below assumes that...
One method is to add a "glass pane" to the canvas in order to capture the
"off" events.
Add a <g> behind all other elements.
ensure that the <g> tag pointer-events="all" or other (see
http://www.w3.org/TR/SVG/interact.html#PointerEventsProperty)
Add a listener for the <g>
you'll have to manage the event bubbling with this method, but it is pretty
easy to implement
Hope this helps,
Jonathan
