[flexcoders] Print datagrid with picture in Flex2 alhpha

Mon, 14 Nov 2005 22:09:50 -0800

Hi, All,

does the Flexprintdatagrid support printing pictures?
when I use the browser's print, it works correctly, while when i use my own funciton of printing, something seems wrong.
and My codes are like this:
PicForm.mxml:

<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml" xmlns:local="*">
   
    <mx:Script>
        <![CDATA[
            // Data includes URL to album cover.
            import mx.print.FlexPrintJob;
               import mx.collections.ArrayCollection;
            [Bindable]
            public var initDG:Array = [
                { Artist:'Pavement', Album:'Slanted and Enchanted', Price:11.99,
                    Cover:'robot.jpg'},
                { Artist:'Pavement', Album:'Brighten the Corners', Price:11.99,
                    Cover:'rover.jpg'}
            ];        
           
            public function dgprint():Void{
                var pj:FlexPrintJob = new FlexPrintJob();
                if(pj.start())
                {
                    var numRows:uint = myGrid.dataProvider ? myGrid.dataProvider.length : 0;
                    trace("!!!ZF, numRows = " + numRows );
                   // var view:FormView = new FormView();
                     var ptl:PrintTL = new PrintTL();
                    ptl.width=pj.pageWidth;
                    ptl.height=pj.pageHeight;
                    addChild(ptl);
                    var length:int = myGrid.columnCount;
                var array:Array = new Array();
                var i:int;
                for(i = 0; i < length; i ++){
                    array.push(myGrid.getColumnAt(i).columnName);
                }
             
                ptl.columns = array;
                ptl.ini();               
                    ptl.pdg.dataProvider = this.myGrid.dataProvider;
                    var headerShift:int = ptl.pdg.showHeaders ? 1 : 0;
                    trace("!!! ptl.pdg.showHeaders ?" +  ptl.pdg.showHeaders);
                    trace("      ptl.pdg.columnCount:" + ptl.pdg.columnCount);
                    if((ptl.pdg.vPosition + (ptl.pdg.rowCount - headerShift)) >= numRows)
                    {
                        pj.addObject(ptl);
                    }
                    else
                    {           
                        pj.addObject(ptl);
                       
                        while(true)
                        {
                           ptl.pdg.nextPage();    
                            if((ptl.pdg.vPosition + (ptl.pdg.rowCount - headerShift)) >= numRows)
                            {
                                if(ptl.pdg.vPosition >= numRows)
                                {
                                    ptl.pdg.height = 0;
                                    ptl.pdg.visible = false;
                                }
   
                                pj.addObject(ptl);
                                break;
                            }
                            else
                            {
                                pj.addObject(ptl);
                            }
                        }
                    }
                    pj.send();
                    removeChild(ptl);
                }
                delete pj;
            }
        ]]>
    </mx:Script>

    <mx:DataGrid id="myGrid" dataProvider="{initDG}"
            variableRowHeight="true">   
        <mx:columns>
                <mx:DataGridColumn columnName="Artist"/>
                <mx:DataGridColumn columnName="Album"/>
                <mx:DataGridColumn columnName="Cover"

        </mx:columns>       
    </mx:DataGrid>       
    <mx:Button id="btn" label="print form" click="dgprint()"/>
</mx:Application>

and the PrintTL.mxml:

<?xml version="1.0" encoding="utf-8"?>

<mx:Script>
    <![CDATA[
        public var columns:Array = new Array();
        public function ini():Void{
            var name:String = "";
            var i:int;
            for(i = 0; i < columns.length; i ++){
                name = columns[i].toString();
                pdg.addColumn(name);
            }
        }
    ]]>
</mx:Script>   
<mx:PrintDataGrid id="pdg">
</mx:PrintDataGrid>
</mx:VBox>
