Here's a version set to the PanQuery widget right now:

http://209.20.81.81/fusion/templates/mapserver/panquery

<Item xsi:type="WidgetItemType">

<Function>Widget</Function>

<Widget>PanTool</Widget>

</Item>

And

<Widget xsi:type="UiWidgetType">

<Name>PanTool</Name>

<Type>PanQuery</Type>

<StatusItem>Drag the map to pan.</StatusItem>

<ImageUrl>images/icons/pan.png</ImageUrl>

<ImageClass/>

<Tooltip>Pan mode</Tooltip>

<Label/>

<Disabled/>

</Widget>

I need the maptips to be always be on, and it seems to break every UI
convention of a tooltip to have it only work some of the time.

So in order to fix this, is it possible to query information without
changing the selection? Alternately, could one store the current
selection, and have maptips revert back to that selection after it does
its query/selection thing?

I'm using the hacked version of pan because when I try to use panquery,
I get two of the pan icons, one disabled and one enabled but not
selectable. However if I just drop the onmouseup select method and event
binding from panquery.js into pan.js, then it works as it is supposed
to.

You should not have this issue if you were to revert it to the the
panquery widget i can tell you why this is happening.

	Well shoot. That's going to be a problem. I suppose I could make
a clone of selection.php just for maptips that returns the same thing
but doesn't trigger a selection event?

The other thing to note is the maptip is actually triggering a "QUERY /
SELECTION" to get the maptip and thus the selection has changed. You can
see the correct behavior if you quickly drag pan it does not get a
chance to fire maptips and then change the selection. 

What you need to do is basically disable the maptips widget when the pan
widget is active. 

Essentially in looking into this further it is the maptip div itself
that is the losing focus issue. when you mouse moves over that div you
loose focus on the map Window causing the pan to fire.

	Thanks for your help,

	Marc

	I would be willing to assist you on getting the panquery widget
to work. 
	Why are you using a hacked version of pan? when panquery is
there?

	heres an example for panquery in appDef

	<!-- CONTAINER-->
	      <Container>
	          <Name>toolbar</Name>
	          <Type>Toolbar</Type>
	          <Position>left</Position>
	          <Item>
	              <Function>Widget</Function>
	              <Widget>FitToWindow</Widget>
	          </Item>
	          <Item>
	              <Function>Widget</Function>
	              <Widget>ZoomIn</Widget>
	          </Item>
	          <Item>
	              <Function>Widget</Function>
	              <Widget>ZoomOut</Widget>
	          </Item>
	          <Item>
	              <Function>Widget</Function>
	              <Widget>PanQuery</Widget>
	          </Item>
	      </Container>

	    <Widget>
	        <Name>PanQuery</Name>
	        <Type>PanQuery</Type>
	        <Description>Click or click and drag to select
features</Description>
	      <Extension>
	            <SelectionType>INTERSECTS</SelectionType>
	            <Tolerance>25</Tolerance>
	            <QueryActiveLayer>false</QueryActiveLayer>
	      </Extension>
	      <ImageUrl>images/icons/pan.png</ImageUrl>
	      <Tooltip>Click or click and drag to select
features</Tooltip>
	    </Widget>

	also if you do not want it to have a "button" for it at all you
can add this to your fusion initialized function and set it active

	function onInitialize() {

	    var map = Fusion.getMapById('mapArea');

	    // activate PanQuery
	    var panWidget = Fusion.getWidgetById('PanQuery');
	    map.activateWidget(panWidget);

	}

	If you want a clue on the "wierd behaviour" it is your map tips
fired event that causes the focus to be lost.  That is causing the
selection to be triggered when you pan.

	Also, there's some weird behavior I just noticed with PanQuery -
when the map redraws, it draws a new querymap based off of a query on
location where you started your click and drag, even though it does not
make the selection there.

	Note that my PanQuery is a modified pan.js, not panquery.js.

	And, is it just me or is the selection highlight not drawn with
the antialiased renderer?

	I'm using 1.1.0 RC1.

	I would like to assist you on this: 

	1. Can we see your application? if not can you post your appdef.
template and supporting js code?
	2. What revision are you using?

	Cheers

	I noticed a few things and now have it working.

	1. PanQuery.js requires Pan.js
	2. I end up with 2 icons. Hmmmmm....
	3. I set PanQuery.js and Pan.js to output a message to console
when
	initializing.
	4. I have a map that only has PanQuery in its
ApplicationDefinition.xml
	5. When it starts, I get messages that both Pan and PanQuery
have
	initialized.
	6. Perhaps it's adding a new OpenLayers control twice, once for
each
	initialization.
	7. Try commenting out the creation and adding of the control in
either
	JS. No dice.
	8. OK, try taking the event binding and the mouseup event method
and
	adding into pan.js
	9. Use query-fied pan.js
	10. Success!

	So I'm not sure why exactly I couldn't get PanQuery.js to work,
but it
	seems to have something to do with the require.
