i have been trying to look the answer actually by googling and so, but unfortunatelly since i have no background at all about GUI programming, i dont know even the keyword for that
i want to generate a pop up window from my program (written in C) which show a message and an OK button. in my opinion, maybe i should use directly the Xlib library and not the GTK or QT library for example so the program can work almost on every linux system.
can anybody give me a code snippet/hint for the pop-up window then?
thanks for any answer
