Hi all,
I need to create a button that get the coodenadas a point. Unfortunately is
the first time that I use the mapbuilder and I have trouble to create this
button.
I wish that you say step by step how to create this button.
I tried to create, but unfortunately the button does not appear in the
button bar.
I shall step by step what I tried to do:
1) Get a file (CoordsPopup.js) with the following javascript content below
and put in the directory mapbuilder/lib/widget
/*
License: LGPL as per: http://www.gnu.org/copyleft/lesser.html
Dependancies: Context
$Id: WfsGetFeature.js 1779 2005-11-01 13:28:05Z cappelaere $
*/
// Ensure this object's dependancies are loaded.
mapbuilder.loadScript(baseDir+"/tool/ButtonBase.js");
/**
* Builds then sends a WFS GetFeature GET request based on the WMC
* coordinates and click point.
* @constructor
* @base ButtonBase
* @author Cameron Shorter
* @param widgetNode The XML node in the Config file referencing this
object.
* @param model The Context object which this tool is associated with.
*/
function CoordsPopup(widgetNode, model) {
// Extend ButtonBase
ButtonBase.apply(this, new Array(widgetNode, model));
// override default cursor by user
// cursor can be changed by spefying a new cursor in config file
this.cursor = "crosshair";
/**
* Open window with query info.
* This function is called when user clicks map with Query tool.
* @param objRef Pointer to this GetFeatureInfo object.
* @param targetNode The node for the enclosing HTML tag for this widget.
*/
this.doAction = function(objRef,targetNode) {
if (objRef.enabled) {
extent=objRef.targetModel.extent;
point=extent.getXY(targetNode.evpl) + "";
pointx = point.substring(0,point.indexOf(","));
pointy = point.substring(point.indexOf(",") + 1, point.length);
pointx = pointx.substring(0,pointx.indexOf("."));
pointy = pointy.substring(0,pointy.indexOf("."));
popup = window.open
("","pointLocation","height=120,width=300,dialog=yes,modal=yes,top=200,left=200");
popup.document.open();
popup.document.write('<html><head><title>Point
Location</title></head><body><table size="100%" border="0"><tr><td>The
selected point\'s coordinates are:<br/><br/>X:' + pointx + "<br/>Y:" +
pointy);
popup.document.write("</td></tr></table></body></html>");
popup.document.close();
}
}
/**
* Register for mouseUp events.
* @param objRef Pointer to this object.
*/
this.setMouseListener = function(objRef) {
if (objRef.mouseHandler) {
objRef.mouseHandler.model.addListener('mouseup',objRef.doAction
,objRef);
}
}
config.addListener( "loadModel", this.setMouseListener, this );
}
2) Added the code in config.xml
<widgets>
...
<CoordsPopup id="coords">
<buttonBar>mainButtonBar</buttonBar>
<targetModel>mainMap</targetModel>
<mouseHandler>mainMouseClick</mouseHandler>
<class>RadioButton</class>
<selected>true</selected>
<enabledSrc>/images/QueryEnable.png</enabledSrc>
<disabledSrc>/images/QueryDisable.png</disabledSrc>
</CoordsPopup>
...
</widgets>
3)Added the code in mapbuilder/lib/schemas/config.xsd
<xs:complexType name="CoordsPopupType"> <!--adicionado-->
<xs:annotation>
<xs:documentation>Geting coodenates</xs:documentation>
</xs:annotation>
<xs:complexContent>
<xs:extension base="mb:AbstractButtonType" />
</xs:complexContent>
</xs:complexType>
......
<xs:complexType name="widgetsType">
<xs:choice maxOccurs="unbounded">
....
<xs:element name="CoordsPopup" type="mb:CoordsPopupType"/>
....
</xs:choice>
</xs:complexType>
4) In widgetText.xml added
...
<CoordsPopup>
<title>Geting coodinates</title>
</CoordsPopup>
...
====================================================
