[Yahor Radtsevich (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBIDE-5042?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12527866#action_12527866 ] 

Yahor Radtsevich commented on JBIDE-5042:
-----------------------------------------

> It is worked in 3.1.0.GA for images at least and I've just verified that.
For me it does not work (see old-dnd-in-tools-3.1.0.swf ). And it should not work according to the source code, where DRAGGESTUREEVENT is just ignored [1].

> Would be good to have a list of "certain problems", wouldn't it? Are they listed somewhere?
Not bad idea. We will create a page in the Wiki for them.

> What about DnD for selected text?
It is not supported now. I have just created a feature request for it:  JBIDE-6229 .

> What cases are supported for marking drop location?
There are 4 cases (drop targets) for marking an element:
 - at the BEGINNING of the element;
 - at the END of the element;
 - BEFORE the element;
 - AFTER the element.
The method VpeTemplate.canInnerDrop is used to know if a drop target is available. If the element under cursor does not support any of these targets, then its closest ancestor that supports them is marked.
