When I use the region checkpoints, and use the drag tool to capture the region, I am unable to preview that image , it just appears as blank white square shape. Is there any modifications i need to do take care in TC setting? If yes then what is it?
Please Help!
Well I can't be certain, but my guess would be that you are using the drag tool across multiple windows/objects in your application. The Regions checkpoint will only match the image of a single window/object OR a single distinct area within a single window/object.
You are probably dragging across multiple objects that the object browser recognizes, and so it probably picks out just one of the objects you dragged across and returns the image of it. In this case it seems to be some Rectangle object that doesn't actually have any image to it (maybe it's not visible).
I am aware of the fact how region checkpoint works. My problem is not able to get the object preview. So just wondering what might be the cause. Tried re-installing TC and checked, faced the same problem.
Is this issue specific to this object or are you getting no previews ever? There shouldn't be any settings you need to change that I know of. If you're never getting a preview of any object then you should put in a support ticket to SmartBear as that sounds like a bug or configuration issue.
But not every object that TestComplete can recognize is going to have an image. Some objects are not visible or are simply empty containers. I'm guessing that specific Rectangle object isn't going to have an image to preview for one of those reasons. In fact that blank white box probably is the Rectangle object, and if there is any image at all it's likely a child object which is contained within the Rectangle object.
