Hello, the admonition of Prof. Ripley to search the documentation to solve my problem helped, today I read a lot more on Tcl/Tk than before ;-) But now I'm stuck again. With the help of my script some functions are plotted on the display, then I ask if the user wants to save it as pdf. In windows I use winDialog and it works. But I can't succeed in Linux. In short: ---------------------------------------------------- X11() ... res <- tkmessageBox(title="Beenden?", message="Vor dem Beenden als PDF speichern?", icon="question", type="okcancel") if (tclvalue(res) == "ok") ... ----------------------------------------------------- So far every thing is OK. Now I want a box the user should fill in the choosen filename (with a default) and then -------------------- pdf(filename) ... -------------------- I experimented with tkgetSaveFile(). But in the moment the user gives the filename the file is not yet generated! And I can't generate it in advance, because the filename is not yet specified. So I looked for a dialog box. [Some boxes are called "dialog boxes" though they only talk _to_ the user (besides the user's "yes" or "no")]. Just a simple box with a text field the user can type in and the value of this field given back. One option was the "modal dialog", but I was not able to pick the essentials out of it. I did not want to press several buttons until the necessary window appears. Also the "editable text window" was not really a solution. Perhaps a small hint again? Richard
