how to shift colors of proxy entities ?
hi,
i developed a function that is intended to recursively change the color of all entities in a block.
it works well for single entities and for block references, but whatever i try on proxies and their dependencies, the color remains unchanged.
i attached a example; if the function is called from the modelspace block, the whole drawing should turn to the color whose index is given as parameter. but as you can see, proxy objects do not change (precisely the washbasin (handle 537e), which is the object i studied and worked on).
is there something i don't understand about proxies? is it possible to change their colors ?
thank you for your help
regards
guillaume

{
// for the current block, search in all entities
oddbobjectiteratorptr pentityiter;
pentityiter=pblk->newiterator();

{
oddbentityptr pentity=pentityiter->entity();
// if the entity is a proxy go through the dependencies to update them as well

attached files
hi,
to display a proxy entity ddt uses the entity's graphics metafile, which contains data derived from the entity's worlddraw() function when the drawing was last saved. the proxy's graphics data saved in attached file contains it's own color setting. so color changes will be applied to proxy (aecdbmvblockref) only when you open the file in a native application (adt).
also note that proxy uses flag to define the types of edits that can be made to the proxy (e.g. kcolorchangeallowed).
