Hello,
I like to exchange the icon of a commanddata plugin. For objects it's working fine with the MSG_GETCUSTOMICON message and set it in GetCustomIconData. But not for a commanddata.
I recieve this message also, but it's not updated the icon.
How does it works for commanddata plugins?
regards
Marky

Well, very hacky one, but you could blit on the bitmap returned by GetIcon();.

oh, sorry, I don't understand. In the commanddata I don't have a GetIcon() function.
Do you have a short exmaple?

There's a GetIcon function in the SDK, lib_customicon or sth like that. Not at home atm.

Something like this, not tested, but should give you the gist of it:
#include <lib_iconcollection.h>
IconData* ico = GetIcon(PLUGIN_ID);
if (ico && ico->bmp) {
BaseBitmap* bmp = ico->bmp;
for (LONG i=ico->x; i < ico->x + ico->w; i++) {
for (LONG j=ico->y; j < ico->y + ico->h; i++) {
Real lower = static_cast<Real>((i - ico->x) * (j - ico->y));
Real upper = static_cast<Real>(ico->w * ico->h);
LONG x = (lower / upper) * 255;
bmp->SetPixel(i, j, x, x, x);
}
}
}
