[flexcoders] CHART + CONTEXTMENU : Create a ContextMenu according to a chart

Tue, 02 Aug 2005 07:44:17 -0700

Hi,
 
I try to implement a ContextMenu for different charts I generate thanks to a Repeater.
For this I face with 2 problems :
- Generate the right menu
- Get the relative data on which I click into the chart
Thanks for your ideas about this problem.
 
I have also 1 question:
- Is there any method allowing me to open the ContextMenu but not only with a right-click?

MXML File
 
<mx:ColumnChart  id="ccChartOneColumn"
               styleName="chart"
               height="160"
               width="100%"
               minWidth="500"
               dataProvider="{ arrCharts[rpCharts.currentIndex].chartData }"
               mouseOverData="{ setDispatchingOptions( event ) }"                    // Method which must create the right Menu, but only with a left-click on the chart before a right_click
               showDataTips="true">

METHOD
 
public function setDispatchingOptions( event )
{
    
 // Alert.show("typeof(event.target) : " + typeof(event.target), "______Message__", Alert.OK);
 // typeof(event.target) = movieclip so event.target.menu should run, shouldn't?
 
 var index:Number = event.target.instanceIndex;
 var itemArray:Array = new Array();
 var boolArray:Array = new Array();
  
 switch (index)
 {
    according to the case I define both arraies' values : itemArray and boolArray
 }
 
 var chartMenu = new ContextMenu();
 chartMenu.hideBuiltInItems();
 chartMenu.builtInItems.forward_back = false; // and so on
 chartMenu.builtInItems.loop = false;
 chartMenu.builtInItems.print = false;
 chartMenu.builtInItems.quality = false;
 chartMenu.builtInItems.rewind = false;
 chartMenu.builtInItems.save = false;
 chartMenu.builtInItems.zoom = false;
 
 Alert.show("chartMenu.builtInItems.loop : " + chartMenu.builtInItems.loop, "______Message__", Alert.OK);
  
 for (var i:Number=0; i<itemArray.length; i++)
 {
  var item:ContextMenuItem = new ContextMenuItem(itemArray[i], openTheDetailsPanel, boolArray[i]);
  chartMenu.customItems.push(item);
 }
 
 mx.core.Application.application.menu = chartMenu;   // I get a Menu but I logically need to click on the graph to update the items. 
 // event.target.menu = chartMenu;   // It doesn't work
}
Thank you so much for all replies on my mails!
