32-bit Intuition Images

I'm trying to initialize a DiskObject structure by hand. I have called NewDiskObject to get an empty object, which is fine, and now I want to set up the Gadget structure with two images, for which data I have somewhere else in memory (that is the reason for doing it by hand: My Image data is in memory and not on disk).

Problem is, when I specify an Image Depth of more than 8, AmiDock just shows some random default image instead of my image in ram. I have tested with GetIconTags, and here the Depth values are all 8, but that doesn't make sense, since the icon shown is 32-bit (at least that's what I think it is).

Comments?

@alfkil The Gadget structure

@alfkil

The Gadget structure and it's associated struct Image pointers is only for legacy planar icon gfx. For 8-bit CLUT or 32-bit ARGB icon gfx you should use IconControl():

IIcon->IconControl(icon,
    ICONCTRLA_SetImageDataFormat, IDFMT_DIRECTMAPPED,
    ICONCTRLA_SetWidth,           width,
    ICONCTRLA_SetHeight,          height,
    ICONCTRLA_SetImageData1,      argb_normal,
    ICONCTRLA_SetImageData2,      argb_selected,
    TAG_END);

@salass00 Thanks for the

@salass00

Thanks for the tip. I can't get it working, though. AmiDock still just shows some default image.
Here's ma code:

	void createAppIconInfo(QIcon &icon)
	{
		info = (struct ApplicationIconInfo *)IExec->AllocVecTags(sizeof(struct ApplicationIconInfo),
				AVT_ClearWithValue, 0,
				TAG_DONE);
		info->iconType = APPICONT_CustomIcon;
		struct DiskObject *obj = IIcon->NewDiskObject(WBTOOL);
		printf("obj: 0x%x\n", obj);
		info->info.customIcon = obj;
 
		QImage imoff = QImage(icon.pixmap(64, 64));
		QImage imon = QImage(icon.pixmap(64, 64, QIcon::Normal, QIcon::On));
 
		UWORD *data1 = (UWORD*)IExec->AllocVecTags(
										64*4*64, TAG_DONE);
		memcpy(data1, imoff.bits(), 64*4*64);
		UWORD *data2 = (UWORD*)IExec->AllocVecTags(
										64*4*64, TAG_DONE);
		memcpy(data2, imon.bits(), 64*4*64);
 
	    ULONG processed = IIcon->IconControl(obj,
		    ICONCTRLA_SetImageDataFormat, IDFMT_DIRECTMAPPED,
		    ICONCTRLA_SetWidth, 64,
		    ICONCTRLA_SetHeight, 64,
		    ICONCTRLA_SetImageData1, data1,
		    ICONCTRLA_SetImageData2, data2,
		    TAG_END);
		printf("processed: %d\n", processed);
	}

And this:

	sys->appID = IApplication->RegisterApplication(name,
										REGAPP_URLIdentifier, version,
										REGAPP_AppIconInfo,	sys->info,
										//REGAPP_FileName, "Work:code/medium/screengrab-0.9.90/build/screengrab",
										REGAPP_AppNotifications, TRUE,
										REGAPP_Description, "Qt app has started...",
										TAG_DONE);

IconControl returns 5, so everything should be in order...

Apparently one needs to call

Apparently one needs to call LayoutIcon to make the changes happen. Strange, because the autodoc says:

"Useful only for palette mapped icons"

...and I am using direct mapped icons. Well...

"palette mapped" in this

"palette mapped" in this context refers to all images that are stored seperately to those in do_Gadget->GadgetRender and do_Gadget->SelectRender. In OS 3.5 (when this autodoc was written) there existed only normal images and palette mapped images.

Ok, so far so good, icons are

Ok, so far so good, icons are working. But now I need to supply a struct Image to the AppDocky context menu. Do I really need to create a DiskObject for that, or is there some smart method to create a 32-bit struct Image??

Well a struct Image stands

Well a struct Image stands alone in memory for display images so no is not part of a DiskObject. Even if a DiskObject makes use of an Image.

What funtion is it? Can the bitmap class help?

Well, I have made the code,

Well, I have made the code, so that IconControl() creates the struct Image for me in full 32--bit. It works, but it is a hell of a detour for such a simple purpose...

I need the struct Image to supply to NewObject("popmenuitem.class"..... PMIA_Icon, ... TAG_DONE); There doesn't seem to be a tag for a bitmap class, and there doesn't seem to be any references to struct Image in the bitmap class.

The BOOPSI/ReAction BitMap class is a sub-class of imageclass, so a bitmap object in fact points to a struct Image. If you create the bitmap image object

Object *bitMapImage = NewObject(...);

you'll then probably need to typecast

PMIA_Icon, (struct Image *)bitMapImage, ...
