Hi Ford, Perhaps you can provide us with an example of the perl code you've already written in attempting to solve this problem ? It sounds like you're trying to extract text from An X or GTK window app in some way, but perhaps you can explain more about that, give a sample application name or something ? Basically, I want to help, but need more details to be able to start. Thanks	[reply]

Hi deorth, Actually it is a Java application and we have to click on specific areas of the window by identifying the text i.e we have to click on dates, numbers, etc. and also extract the text which is displayed on another area of the window. And this application is run on UNIX OS. I hope I have cleared your doubts. In case it is still not clear, please let me know. Thanks in advance. Ford.	[reply]

I found this in response to another node, and it has a blurb about getting text. Maybe you can capture an image and OCR it?	[reply]

hi, The application is a java application which runs on UNIX OS. The win32::guitest module that you are referring to does not install in UNIX platform. Can you suggest some other modules which works on UNIX?	[reply]

It really depends where the text you want to extract is located. If the text is in the window title, then you need to call XGetWMName and/or XGetProperty(NET_WM_NAME) ( the latter is available in X11::Protocol , possibly the former also). If the text is in some selectable text areas, selecting these with mouse will get the text copied in the X clipboard, which can then be accessed again by X11 core calls (XConvertSelection/XGetWindowProperty). Note that X clipboard is more complicated than win32 clipboard because you also need to track X11 events. Finally, if none of these, I don't know if there's any generic way to query text from arbitrary application, and your best bet would be indeed, as suggested, to use OCR. Take a look at OCR::Naive that does exactly this.	[reply]
