[求助]：打开实体返回eWasOpenForRead(急)

wowolwj

通过acednetsel获得实体.然后acdbOpenAcDbEntity(pEntity,ObjId,AcDb::kForWrite);返回eWasOpenForRead(82).
无法以写的方式打开实体进行编辑,怎么办?

cyr

因为pEntity实体以作为AcDb::kForRead打开,所以出现eWasOpenForRead的错误你可以用pEntity->upgradeOpen()

wowolwj

非常感谢.我试了下用pEntity->upgradeOpen() 后只能获得实体的属性了,但是不能修改呀!

肯定能修改的，但是记得修改完属性后调用downgradeOpen();函数，否则可能出错。

cyr

downgradeOpen()这个可能不一定用,我是没有用过,upgradeOpen()函数本身就是有Read改为Write的意思,你肯定还有别的地方有问题

在打开实体对象后，调用这个函数试一试看能不能解决问题
void recordGraphicsModified(

Adesk::Boolean autoUndo = true);

autoUndo Input Boolean value to indicate if the entity's graphics should be updated on screen when the object is closed

This method sets the entity's state to indicate whether or not the entity should be updated on screen when it is closed. If the entity is set not to update, then any changes made will appear the next time the entity is regenerated.

If setModified == Adesk::kFalse and the entity is currently set to update its graphics on close (which is its default state), then this function sets the entity so that it will not update on screen when it is closed and objectModified notification is sent to all entity type reactors attached to the entity. If setModified == Adesk::kFalse and the entity is already set not to update its graphics on close, then this function simply returns.

If setModified == Adesk::kTrue, then the entity is set to update on screen when it is closed

可以44以write的方式打开......
如果不可以再看看楼上的,好好改改.
