<i>ol/interaction/UndoRedo</i> is an interaction to handle undo/redo on a map.
|
|
</p>
|
|
<p>
|
|
<span class="experimental">Experimental</span>
|
|
this feature is still in progress and may be buggy.
|
|
</p>
|
|
<p>
|
|
Just add the interaction to the map to get it working.
|
|
It will watch all vector sources and all interactions in the map.
|
|
Use the <i>undo</i> and <i>redo</i> method to undo the last recorded operations.
|
|
<br/>
|
|
Undo can be stacked in a block to make them undoing at a time.
|
|
Just enclose the operation between a <i>blockStart()</i> and <i>blockEnd()</i>.
|
|
<br/>
|
|
You can stack operation on a map by enclosing operations beetween
|
|
<i>undoblockstart</i> and <i>undoblockend</i> events
|
|
(<i>map.dispatchEvent('undoblockstart')</i> and <i>map.dispatchEvent('undoblockend')</i>).
|
|
</p>
|
|
Cancelable operations:
|
|
<ul>
|
|
<li>
|
|
<b>ol/source/Vector</b>
|
|
<i>addFeature</i> / <i>removeFeature</i> / <i>clear</i>
|
|
<br/>
|
|
The core <i>clear</i> function has been overwritten to fires
|
|
a <i>clearstart</i> and <i>clearend</i> event
|
|
</li>
|
|
</ul>
|
|
<br/>
|
|
Cancelable interactions:
|
|
<ul>
|
|
<li>
|
|
<b>ol/interaction/Draw</b> (ol core interaction)
|
|
</li>

<a href="../interaction/map.interaction.modifyfeature.html">
|
|
<b>ol/interaction/ModifyFeature</b>
|
|
</a>
|
|
The core <i>ol/interaction/Modify</i> has been rewritten to handle modification
|
|
start / end events
