Is it possible to use a fuelgauge inside a listbrowser using reaction?

I *think* a listbrowser can only contain either text or boopsi objects based on the image class (as set by LBN_Text and LBN_Image, respectively).
I guess fuelgauge doesn't extend image?

If you find a solution I'd be all ears, though.

Use a rendering hook and draw the gauge "yourself".

uint32 RenderMyGaugeFunc(register struct Hook *hook, register struct Node *node, register struct LBDrawMsg *msg)

{
 if (msg->lbdm_MethodID!=LV_DRAW) return(LBCB_UNKNOWN);

 IGraphics->SetAPen(msg->lbdm_RastPort,3);
 IGraphics->RectFill(msg->lbdm_RastPort,msg->lbdm_Bounds.MinX,msg->lbdm_Bounds.MinY,msg->lbdm_Bounds.MaxX,msg->lbdm_Bounds.MaxY);

 return(LVCB_OK);

}


IExec->AddTail(MyLBContent,IListBrowser->AllocListBrowserNode(1,
                                              LBNA_Column,0,
                                              LBNCA_RenderHook,MyGaugeHook,TAG_DONE);

struct Hook *MyGaugeHook=IExec->AllocSysObjectTags(ASOT_HOOK,ASOHOOK_Entry,RenderMyGaugeFunc,TAG_DONE);

I couldn't find gauge.h from the SDK/images.

Correct. It's a built-in class. Ad-libbing a bit here, but something like this should work:

struct Image *gauge = (struct Image *)NewObject(NULL, "gaugeiclass", IA_Label, "Gauge label", GAUGEIA_Level, 50, TAG_DONE);

blah, blah, blah, whatever your creation function is, with LBN_Image, gauge,


The available tags are documented in the gaugeiclass Autodoc.

Thanks ! I was trying to use NewObject(NULL, "gauge.image", ... With "gaugeiclass" it works. I was wondering what "being built-in class" means.

Do you know how table.image works ?

It couldn't have worked because the public class ID is "gaugeiclass", not "gauge.image".

It means that the class is part of the Intuition module and does not reside in SYS:Classes/ just like most other BOOPSI classes.

No, because we haven't had an SDK update since it was released, so there's no documentation.
