You're creating the icons with negative y co-ordinates, and then setting the window y extent from 0 to a positive number. This means the icons will be positioned outside the viewable area of the window. shouldn't the window's vertical size be
min -(3*44)+(2*8 )
max 0 ???? However I reserve the right for all that I have said above to be utter tosh.

Dig out your AUCD1 and look through the Acorn Computing Coverdisks. There was an article by Ben Summers about using files, and there was a neat little example which did exactly what you want. It might have been in a directory called 'UsingFiles'.... |

Hi, /me hangs head in shame and asks the following: How do you create new icons in BASIC, and then resize the window around them? I can do one or the other, but both together seems to disappear the icons  I've knocked up a small test program which loads a shell desktop app; it loads a template file with a blank window and I can create some icons on it using Wimp_CreateIcon, and when I click on these icons they report back icon 0,1,2... etc. has been clicked on. Using Wimp_SetExtent resizes the window to the correct size, but the icons aren't there, whether I create them before or after the resize. I'm guessing the window can't tell how many icons are on it, so it's falling back to 0; but poking the number of icons to windowhandle%!84 results in Very Bad Things happening A bit more info is at http://www.houseofmabel.com/rich_is_thick/ - there's a small image of a working version of what I want the code to do, but that's using a cheating pre-defined template. I need to create a menu-like window that can grow or shrink depending on how many items are on it, but can display 24bit colour icons under RISC OS 3.x |

[BTW, anyone got any nice, easy code for recursive directory searches while we're here?  ] |

Okay, tried that but no joy. (Especially as the CD is in such bad shape it crashes CDFS, so I have to use a PC and LanMan... ) Anyone got a copy of said file? |

I've got one, but unfortunately it's written in C.  |

Already done - see here Edit: Doh, I didn't read your message properly, I thought you meant the icon thing. Although I have already got some recursive directory code too in the desktop themes prog. |

Do you know when that'll be finished? |

Erm, RSN...  Look, I took the weekend off to go see my Mum, that's more important than programming! |
