Quote: I don't see how it can be considered a commodity as I cannot remove it from the system nor that I can disable it. 
I thought this was the meaning of a commodity in the first place.
Newstring.mcc adds itself as a commodity broker only to be able to catch certain events from the input stream for its handling of i.e. RAmiga+C or RAmiga+V. Being a commodity makes this stuff really easy. But it does not react on the usual stuff like being killed or switched inactive, because there is only one single broker for all instances of Newstring.mcc no matter which application uses it.

This cannot really work, because you are passing the result of a MUI_NewObject() call (inserted by the BitmapObject macro) as single tag without data to your own NewObject() call. If your "mcc" variable is a subclass of Bitmap.mui, then the correct call must look like this:
Child, Im_Data_full_bmp = NewObject(mcc->mcc_Class, NULL,
MUIA_Bitmap_Width, width,
...
TAG_DONE),
The same applies to a subclass of Dtpic.mui. You can pass all attributes directly to the NewObject() call. Please note that the OM_NEW method of your own class must pass all attributes it receives to the DoSuperMethod() call via TAG_MORE. For reference take a look at YAM's source of its Shutdown window. It is a very simple class which consists of a constructor only. The inittags() macro looks like this:
#define inittags(msg) (((struct opSet *)msg)->ops_AttrList)
Quote:
1) why the scrollers failed to operate with my Bitmap (it fails with or without mcc_class) ?
This most probably fails because of the wrong object creation. Quote:
2) if it possible to create a NewObject DtpicObject like that ?
No, see my explanation above.

Take the Virtual demo source as reference. The upper left virtual group does exactly what you want, except that it is showing a simple text instead of a bitmap.

This should work in principle. I did not test this code, but wrote it just from memory right now.

Re: IFACE for devices in a library

Quote: Question is: why for timer IFACE is not necessary, but necessary for console.device. Obtaining an interface is only necessary if you are calling one of the library functions of a device later. RawKeyConvert() is one of console.device's library functions. If you are using device IO only then obtaining the interface is not necessary. As a thumb rule you must obtain the interface if there is something like this in the code (for m68k): Quote:
// Get device base pointer
ConsoleDevice=console_req.io_Device;
For m68k the device base is the same as a library base to be able to call these functions. If you need to call timer.device functions like AddTime() or GetSysTime() then you must obtain the interface for timer.device, too. Quote:
clipboard.device
trackdisk.device
diskspare.device
floppy.device
mfm.device
None of these devices offers any directly callable functions, only regular device IO via DoIO/SendIO/BeginIO is possible.

Quote: I create the MUI_Bitmap by passing to it a Bitmap struct created by Datatype. What happens to the DT object after you obtained the bitmap from it? Of course it must stay alive as long as the bitmap is used by your Bitmap object, because DisposeDTObject() will free all stuff belonging to the object, including the bitmap you obtained before. If you implemented things really this way, the you must clone the obtained bitmap before you dispose the DT object and use the cloned bitmap for your Bitmap object.

Quote: Thank you by advance if you have a clue (even if you don't have...) Well, there is nothing special in the log except that the crash is finally happening in rtg.library. How do you create the bitmap? Is it possible that it might become invalid when the application is iconified and hence invalid pointers will be accessed upon uniconification?

set(object, MUIA_Bitmap_Bitmap, newBitmap)
Most probably you didn't use MUIA_Bitmap_SourceColors then (or any other attribute which might cause the bitmap to be remapped). In this case setting a new bitmap will correctly redraw the new one. Otherwise you will also trigger a redraw event, but still with the old bitmap. Quote: For AROS's Zune I did have to kludge it to refresh, but I assumed this was a bug since MorphOS as well as OS4 when I do it. Here was my kludge (don't do this at home!) :
set(object, MUIA_ShowMe, MUI_FALSE)
set(object, MUIA_ShowMe, MUI_TRUE) This is almost the same as removing and readding the bitmap object, but a little bit worse as this will effectively cause two refresh cycles instead of just one. Quote: @tboeckel
Any idea why it works for me? And why doesn't MUI act intelligently & refresh the bitmap when it is changed (in some circumstances anyway)? I cannot really tell why stunzi implemented it this way. I guess it was done this way because usually people use the set() macro instead of SetAttrs() directly. The macro allows to modify one attribute with each call only. The point is that modifying the bitmap might require more than one attribute to be changed (mask, colors, etc). Setting all these attributes with single set() calls instead of one SetAttrs() call would have resulted in a redraw action for each set() call. And even worse it even might cause graphical garbage if the old mask is applied to the new bitmap.

Quote: #ifdef __amigaos4__
#define INTUITION_PRE_V36_NAMES
#include <intuition/iobsolete.h>
#endif intuition/iobsolete.h is already included by several other include files, i.e. intuition/screens.h. Hence most probably it has been included already at the time you do it explicitly and therefore your own definition of INTUITION_PRE_V36_NAMES comes a bit too late. Better add -DINTUITION_PRE_V36_NAMES to the CFLAGS definition in your Makefile to make sure that the symbol is always defined.

Is there another switch or the only way is to copy+paste defines to code ? The symbol must be named "INTUITION_PRE_V36_NAMES" and not "__INTUITION_PRE_V36_NAMES__". And you must define it before including intuition/iobsoletes.h.

You will have to take a little detour to enforce the necessary relayout of the bitmap object. Take this object definition for example:
grp = HGroup,
Child, bm = BitmapObject,
MUIA_Bitmap_Bitmap, initialbitmap,
...
End,
End;
To set a new bitmap do this:
if(DoMethod(grp, MUIM_Group_InitChange))
{
DoMethod(grp, OM_REMMEMBER, bm);
SetAttrs(bm, MUIA_Bitmap_Bitmap, newbitmap, ..., TAG_DONE);
DoMethod(grp, OM_ADDMEMBER, bm);
DoMethod(grp, MUIM_Group_ExitChange);
}
The relayout is enforced by removing and readding the bitmap object.

Re: MUI : How to update image filename of a DTPic when running ?

Quote: If this is true, then DTPic might internally keep the pointer to the file name and if you set the same pointer a second time, it thinks the image didn't change and thus doesn't update the display. That's true. Dtpic.mui just remembers the string pointer passed to MUIA_Dtpic_Name and does NOT copy the string. Second, during OM_SET it will check if the pointer changes first. Third, NULL is no valid value for MUIA_Dtpic_Name. Since the string pointer is remembered you must use a different buffer to change the image. Something like this will NOT work: char buffer[64]; snprintf(buffer, sizeof(buffer), "%s/foo.png", path); set(dtobj, MUIA_Dtpic_Name, buffer); snprintf(buffer, sizeof(buffer), "%s/bar.png", path); set(dtobj, MUIA_Dtpic_Name, buffer); However, this will work: char buffer1[64]; char buffer2[64]; snprintf(buffer1, sizeof(buffer1), "%s/foo.png", path); set(dtobj, MUIA_Dtpic_Name, buffer1); snprintf(buffer2, sizeof(buffer2), "%s/bar.png", path); set(dtobj, MUIA_Dtpic_Name, buffer2); I will add an appropriate comment to the attribute's Autodocs for the next release.

Quote: The link you provided already proves that this stuff is implemented since 2 years now. Changing the image of a Dtpic object definitely works, I just checked it myself with both MUI 3.9 and MUI 4.0. I took the Class1 demo source and just added these few lines: within the window creation:Quote:
Child, img=DtpicObject, MUIA_Dtpic_Name, "ram:img1.png", End,
Child, b1=KeyButton("Image 1", '1'),
Child, b2=KeyButton("Image 2", '2'),
after the window creation:Quote:
DoMethod(b1, MUIM_Notify, MUIA_Pressed, FALSE, img, 3, MUIM_Set, MUIA_Dtpic_Name, "ram:img1.png");
DoMethod(b2, MUIM_Notify, MUIA_Pressed, FALSE, img, 3, MUIM_Set, MUIA_Dtpic_Name, "ram:img2.png");
