Hi folks,

I'm wondering how to invoke an update of the object description in the attributes manager in r12. To be precise, when I change something in the object's description e.g. a combobox value, I have to update an ImageButton to display another thumbnail. The button settings are being updated (the bitmap gets redrawn) but the gui does not refresh. In r13 or later I can use node- >SetDirty(DIRTYFLAGS_DESCRIPTION) which I call in SetDParameter(GeListNode *node, ...) , but I couldn't find a corresponding flag or function in the r12 sdk.

Thanks in advance!
