clicking on a class always causes its selection status changed in the navigation panel

[GoogleCodeExporter]

What steps will reproduce the problem?
1. open an eHOST project.
2. go to the Navigation Panel.
3. Check/Uncheck the class item by clicking places that are out of the 
"checkbox".

What is the expected output? What do you see instead?
Result: 
The checkbox is selected/unselected unexpectedly. Sometimes, we just want to 
select this class in the Navigation Panel.

What version of eHOST are you using? On what operating system?

Please provide any additional information below.

Which data batch are you using to test eHOST?

Added a function to locate where the user clicked, and now, there are two ways 
to select/unselect a checkbox:
1. directly click the check **"box"**.
2. double click the component.

Difference:
Any single click, which is out of the 25*25 rectangle from the top-left corner 
of this component, will **NOT** change its selection status.
