- Apr 2 6:45 AMAbouy the simplest I can go is the following. Are you looking at the
Help files? Have you tried the supplied lessons?
Do you know how to 'single step' through a program with the 'bug' icon
next to the 'run' arrow icon?
If so, try the following and try modifying it.
Don't expect to do everything immediately!
' We don't need the text-only 'mainwin' but it may help debugging
' by allowing us to see values.
' But we DO need a graphicbox #w.g in a 'Window' called #w.
' Choose size and position on your screen of this window (allow for
' Measurements all are referred to the top left.
' For the big window #w, it will be started 10 below & 10 to right of
' Its size will be 530 wide by 560 vertically, but this includes
' 10 dsideways & 10 down form this window top left corner we put a 500
by 500 drawing area.
WindowWidth = 530
WindowHeight = 580
' Fit a 500 by 500 box to draw graphics with a nice border gap.
' The graphic area is 'addressed' (referred to) as #w.g, called its
' The whole window has handle #w. #w.g is a 'child' of the main #w.
graphicbox #w.g, 10, 10, 500, 500
' Open the window showing this empty graphicbox
open "Example for Kurt of Simple Graph" for window as #w
' From here on, commands starting '#w, ....' or #w.g, ....' send
' the full window, or to its graphic subwindow.
' Make sure clicking 'close' icon at top RH of #w exits cleanly.
#w, "trapclose [quit]"
' Tell LB to put printing 'pen' down on page.
' Pen at this stage will be at ( 0, 0), at top LH of graphic area.
' Move to a position 100 sideways and 200 down, leaving a line.
#w.g, "goto 100 200"
' Change color and size
#w.g, "color red"
#w.g, "size 4"
' Move to 200 sideways and 100 down, leaving no line.
#w.g, "up ; goto 200 250 ; down"
' Lift pen, move to center-screen at 250, 250 and draw a colored circle.
#w.g, "goto 250 250"
#w.g, "color red ; backcolor cyan ; circlefilled 80"
' Come to here only if 'close' icon clicked.
' Shut the window
' Tell LB the program has ended!
