[求助]：修改后的实体怎么能立即更新 急 ！！！

zhoufs_1205

我做了一个DockControlBar，在上面修改实体后，实体不立即更新，只有当鼠标离开DockControlBar后才更新.
        acDocManager->lockDocument(curDoc());
        acdbOpenAcDbEntity(pEntity,objId,AcDb::kForWrite);
        if(pEntity)
        {
                pEntity->setColorIndex(256);
                pEntity->close();
                pEntity=NULL;
                acedUpdateDisplay();
                acedRedraw(name,1);
        }
        acDocManager->unlockDocument(curDoc());

我用了acedUpdateDispaly()和acedRedraw()都没用，是否有其他函数，请给位帮忙

我上传了一个图片，我想实现在“特性”对话框中修改了实体后，实体能立即更新，但我现在是修改后只有当鼠标离开对话框后才更新，（我自己做了一个“特性”对话框）

在acedUpdateDisplay()之前，试试如下函数：actrTransactionManager->flushGraphics();如果管用请说一下。

//此法有效
acDocManager->lockDocument(curDoc());
acdbOpenAcDbEntity(pEntity,objId,AcDb::kForWrite);
if(pEntity)
{
pEntity->upgradeOpen();///!!!!!!!!!!!!!!!!!!!!!!!
pEntity->setColorIndex(256);
pEntity->downgradeOpen();///!!!!!!!!!!!!!!!!!!!!!!!
pEntity->draw(); //更新实体
pEntity->close();
}
acDocManager->unlockDocument(curDoc());

你就差那么一点就会找到答案。

准确的说法应该是当 [B]Acad编辑窗口 获得输入焦点[/B] 才更新
既然如此那么就让鼠标“进入” Acad编辑窗口吧。
...
acDocManager->lockDocument(curDoc());
acdbOpenAcDbEntity(pEntity,objId,AcDb::kForWrite);
if(pEntity)
{
pEntity->setColorIndex(256);
pEntity->close();
}
acDocManager->unlockDocument(curDoc());
//让Acad编辑窗口 获得输入焦点
[B]acedGetAcadDwgView()->SetFocus();[/B]
...

用Modeless对话框也会碰到类似问题，DialogBar实际上就是一个无模式对话框.

对实体用AcDbEntity::recordGraphicsModified方法，使用Adesk::kTrue参数，实体关闭后，将UPDATE。你使用的acedUpdateDisplay(); 仅仅是刷新屏幕，而实体不重新生成，对实体设置了上面的位后，实体关闭后，将重新生成。

void
recordGraphicsModified(

    Adesk::Boolean setModified = Adesk::kTrue);

setModified        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.

我也是这么做的，为什么在AutoCAD中运行时出现 eWasOpenForWrite 的错误呢？

又学到了一点东西,嘻嘻

/刷新显示
void refreshDisplay()
{
        actrTransactionManager->queueForGraphicsFlush();
        actrTransactionManager->flushGraphics();
        acedUpdateDisplay();
}
