which is best way get mouse cordinates for one speffic window. way where 0,0 is top point of window way where area which is in window borders first point in left and top is 0,0. and way where code or operating system cares different border sizes itself. is related doing "Painting" window. or is this way for AmigaOS4.1 what which cares such a thing:
http://wiki.amigaos.net/wiki/Intuition_Mouse

Thing what is i need seems GZZ mouse coordinates what i get how? if i understand correctly. But now must think how i can read such values only when window what i want this info is active i think there is maybe intuimessage which tells window is active ? at least older amigaoses if quickly look have such thing. and then window isactive i read coordinates when all is fine... only thing is this kind mousecordinates available?

GimmeZeroZero changes how the window is handled in terms of drawing - and I will always recommend against using it. To get 0,0 based coords, simply substract window->Left/Top edges from the coords you get in the IDCMP.

@Vanhapolle

Well... are you trying to obtain infos about a window that you do not control?

If not, yes, there's IDCMP_ACTIVEWINDOW or so.

Perhaps if you've explained what you're trying to achieve, it'd be easier to help you.

@jacadcaps

you mean window->Left i subtract such value form x coordinate and window->Top foem y coordinate?
and there window is stuff what window opening functions gives me when window is opened ? fine if wokrs this way.

If i understand you correctly my one my program window when is active i want coordinates for just this window is going painting window of graphics program.
Other windows are fpr example selecting brush etc.

@Vanhapolle

It would be lot easier if you were not using such low level APIs.

First of all, if you use default window open options, each window has its own UserPort, so when a IDCMP arrives you know the window by the port - there's also a window pointer in the IntuiMessage itself so you can use that and figure out if your window is active by checking for the WLFG_ACTIVE or so flag in window->Flags field.

@itix

How you then solve window in MOS where i have bitmap which i can update after opening window? and get mouse place which i can use to paint tools whicjh modify this bitmap. And i say MOS becouse i understading you mainly know current MOS coding.
ps. btw very likely my project is going AOS4.1 becouse i dont have maybe skills maintain all platforms and some tools work poorer (Photogenics 1.2a at least yester day worked oddly i look soon again) wtih MOS3.7 than MOS1.4.5 which i also need.:(
ps. my project is still trying need these old Photoenics form software what i need. But verylikely i cannot remove all points use of it.

If you use low leve API then you just substract window LeftEdge/TopEdge and bitmap drawing location from mouse coordinates. But Jaca already explained this stuff to you and he knows Intuition better than anyone else here.

In MUI it is easier but since you are not using it I am not going to explain it.

Who knows what i going use? i am not sure yet. When i have time and AmigaOS4.1 i can compare is Reaction or MUI easier for me.
ps. MOS native coding is thing what i maybe also test soon. and to Mos i bet i going use MUI.

Even is hard get info how MUI differens different platforms. and what else often important (all differencies is hard know) differencies are than memory allocation.

@Vanhapolle

Get them from the Window structure. Then adjust the coordinates by the offset of the gadget you are drawing into.

You need to transpose those coordinates in to "project space" too if you support and scrolling or zooing in your image processing program.

Don't use a GMMIZEROZERO window unl;ess you got a very good reason.

Is VERY hard wait AmigaOS4.1 Final edition.
ps. of course i can code classic AmigaOS and Morphos but becouse they work so different way i think coding them not help learn AOS4.1 coding not at least things what i now want mainly check. At least when Reaction coding is different and i understanded even mui have differencies beetween all these systems.
And what i quickly looked MOS MUI docs bitmap/image classes are unsuitable for this special use. hard describe better. Maybe reaction Image element works.

@Vanhapolle

MUI bitmap and image classes are meant to display images but are not designed for use for image drawing. You need a custom class for that where you render graphics to display area using your own code.

Well, in light of today's announcement, hopefully not *too* much longer now.

I'm hoping to take more of a dabble in Amiga programming when I get 4.1 too.
I tried to get into it with 4.0 but found the tools/resources available quite limited and my interest petered out.

The resources for 4.1 seem a bit more comprehensive so I'll take another look and see if I can learn something.
