    Problem Description

    Hi, firstly very much impressed with your work which is very heipful to begginers and thanks a lot.heart

    I want to draw a real time 2D image which is done let it be polygon. But now I want to draw a line connecting the two sides of polygon where the connecting line end points will be given by mouse button. Difficulty is that when I click a mouse button (press), line has to start and it should end when the button releases as same as selecting a line option in power point. your tutorial on cursor functions is almost near but I could not make use of it beceause I am a begginer. This may be easy task for you. Please help me. Thank you sir.

    Do you want the line to only be drawn after the second click or to be dragged in real time after the first click?

    actually I am plotting data of 2D room. now I have to connect the wall with mouse. so that when I first clicks the mouse button line should start at that point and keeps on drawing the path of cursor. when I release the mouse button the line should be fixed. where pressing and relesing button should be end points. and also I want to give a name to the line or to display the distance. How to do that?

    As of now I able to draw the line but how to display some text near line on that glut window?

    thank you
