Re: [Update REQ 6867]: `Pause until key is pressed'
Tamara, Thank you for your reply to my earlier question. I would not wish to unecessarily take up your time... But I have added a bit of background to the question. The set up is that I am giving the talk with `Magicpoint'. Magicpoint is a line based presentation package. At the relevant points in the talk, there is a line in the magicpoint file: %system "geomview -ogl -nopanels <gcl file>" This behaves just as one would expect. I have added `window <position> commands at the beginning of the gcl files to position the camera in the right place on the screen. ----------- Your `freeze' suggestion has the problem (as you say) that execution continues. The soluution with loading in the files would seem to work. I guess my objections to this, are 1) the file panel takes up a lot of space on the screen, 2) I have no doubt I will feel nervous giving my talk, and pressing various buttons etc, surely multiplies the possibilities for errors, and 3) the process of loading up files will interrupt the flow of the talk. I have had three ideas for possible solutions. 1) Just break up the gcl files into the relevant sections, and having in the magicpoint file: %system "geomview ... filePart 1" %pause (which is a command to magicpoint to stop until a key is pressed) %system "geomview ... filePart 2" The disadvantage of this is the nasty flicker caused by opening and closing the geomview camera windows. This is particularly pronounced because geomview, by default, opens the camera window in the `wrong' place. (I can not get the -wpos option working.) 2) I thought I could add a `shell (read n)' command to the gcl file at the point where I want a pause. This, I imagined, would mean execution gcl file would stop until something was typed in. But in fact the camera window goes grey and everthing grinds to a halt! -I dont much (anything?!) about command shells etc. I dont know what going on here... 3) In the man pages for geomview I noticed the geomview -M option and the `togeo mview' command. This, it seems, might give a better version to solution 1). -I should have lines: %system "geomview -M filePart 1" (loads the objects and does something) %Pause (wait until key presses) %system "togeomview filePart 2" (send geomview more gcl commands to the object s already in the camera window) in my magicpoint file. This would be better, because there would be no need too pen and close windows, and to reload the objects. --But I cant sort this out! All this stuff about pipes... ho hum. I will try to track down our `local expert' tomorrow. But if you do have any suggestions, I would be most grateful to hear them. With thanks! Paul.
