How can I access the ITEM SELECTOR from M68000 ? Is it a 'C' only thing ?
I cant seem to find it in any of the GEM books I have .
Thanks in advance ,

I have some questions about GEM: 1/ How do I put the mouse at a specified location on the screen ? 2/ How do I bound the mouse to a box xmin-xmax,ymin-ymax ? 3/ What does the GEM function CELLARAY and how do I use it ? Eric

Every program I've had with it drove me crazy because invariably my mouse would run out of room, and having to pick it up and put it back down closer to me is bothersome. >2/ How do I bound the mouse to a box xmin-xmax,ymin-ymax ? I imagine it could be done by checking mouse position, and calling initmous if you exceeded the limits, but ther is probably a better way. >3/ What does the GEM function CELLARAY and how do I use it ? I've never seen it used. Apparently, it divides the screen up into rectangles, each of which has an associated color. When a graphic operaion would draw, the color drawn would be the color of the rectangle in which the pixel lies. I wonder if this function takes over the screen, making it difficult to use other colors? To get around that, if needed another virtual workstation could be used, I suppose. > Eric +-----------------------------------------------------------------------+ | Kitakaze Tatsu Raito Neil Gilmore internet:gilmore@macc.wisc.edu | | Jararvellir, MACC, UW-Madison bitnet: gilmore@wiscmac3 | | Middle Kingdom Madison, Wi | +-----------------------------------------------------------------------+

domen@wiener.crin.fr (Eric Domenjoud) asks: | 1/ How do I put the mouse at a specified location on the screen ? You need to intercept the mouse cursor change vector, which is an interrupt routine, and feed the coordinates you want to the AES. Check the vex_motv() function documentation in whatever books you're using. | 2/ How do I bound the mouse to a box xmin-xmax,ymin-ymax ? With your own mouse interrupt handler installed, you can effectively limit the motion to whatever you want by discarding any mouse movement that causes the cursor to go outside of your bounding box. | 3/ What does the GEM function CELLARAY and how do I use it ? The cellarray VDI function is not supported in TOS. -- ||| Ken Badertscher (ames!atari!kbad) ||| Atari R&D System Software Engine / | \ #include <disclaimer>

I wrote a little program to pop-up a menu whereever the left mouse button is clicked. The menu consists of a hand-built object tree, basically pretty simple stuff. The problem I am having is with the mouse pointer!! I know that the AES records the # of times you GRAF_MOUSE(M_OFF, 0L), and that you must issue an equal # of M_ON's to restore the mouse. My question: Is there anyway to over-ride this mechanism? If not, is there a way to find out how many times the mouse has been hidden (not counting mousehidden in msh!). I am using MWC 3.0.5, a .5meg ST, and the tos 1.0. Any help would be greatly appreciated! thanks, -Daren daren@umbc5.umbc.edu

I believe that the VDI routine show_mouse(vdihandle, 0) will accomplish the task. -Joe Gilray
