Hi people, I am a beginner with SmallTalks. At the moment I understand the basics about the language but very little about the graphical interface... Can you recommend me docs and tutorials on how to do something like this in Pharo? http://angg.twu.net/eev-videos/2022dragABC.mp4 The link above is to a video that is 20 seconds long. In the first 15 seconds (suggestion: ignore them!) I use weird Emacs tricks to draw three objects in a Tcl/Tk canvas - the letters A, B, and C - and to bind "mousebutton1 motion" to different actions in each of them... ...and in the last 5 seconds of the video I draw the letters A, B and C with the mouse to show what are these actions. In short: the letter A moves freely, the letter B moves in the same horizontal line as A, and when I drag C around it moves B horizontally to force B to be in the same horizontal line as C. Thanks in advance! =) Eduardo Ochs http://angg.twu.net/#eev
