Text from dialog box can't be selected and copied. in the question: How can I copy text from dialog boxes and menus? I find a suggestion to make a screenshot and read the result with an OCR. The above question is related to Japanese text, but I have the problem with plain english text. Can You suggest a less complicated way to extract text from dialog boxes? Or may be this problem comes from a bug? Note:If I create a dialog box from terminal using zenity the text in the box can be selected and copied.

    I am afraid it is very hard to use a generic procedure to intercept the content of a dialogue box, if possible at all. It depends on the application, the (programming) language etc. There is not one general way to generate dialogue boxes. – Jacob Vlijm Oct 26 '16 at 12:46

    My problem is not with a dialog box from an application but with dialog boxes generated by Ubuntu system, for example now I have on the screen a crash report with Title: update-manager crashed with liblibclient0 in_show_transaction ... and would be very useful if I can cut this text to use it for a search on Google... – Corrado Venturini Oct 26 '16 at 15:20

    This should be standard in every OS. – Moilleadóir Oct 08 '17 at 04:30
