flex分页打印操作实现代码
Flex #flexprintjob #分页打印2014-04-10 09:51
1.使用FlexPrintJob进行打印操作
1.如果没有分页和下拉框的时候
public function doPrint() : void {
var printer: FlexPrintJob = new FlexPrintJob();
if (printer.start()) {
printer.addObject(body);
printer.send();
}
}这个方法即可下面的可以使用,由于我使用的是Flex3,
Flex3里面没有标签“PrintDataGrid”,只有“PrintAdvancedDataGrid”。所以下面就使用(“PrintAdvancedDataGrid”,“AdvancedDataGrid”,“DataGrid”)这三种方式,切记上面的方式只适合于单个页面(数据较少)且没有下拉框
< mx: PrintAdvancedDataGrid id = "body"x = "188"y = "232" > <mx: columns > <mx: AdvancedDataGridColumn dataField = "username" / ><mx: AdvancedDataGridColumn dataField = "password" / ></mx:columns>
</mx: PrintAdvancedDataGrid >
--------------------------------------------------------------------------------------
<mx: AdvancedDataGrid id = "body"x = "188"y = "232" > <mx: columns > <mx: AdvancedDataGridColumn dataField = "username" / ><mx: AdvancedDataGridColumn dataField = "password" / ></mx:columns>
</mx: AdvancedDataGrid >
-----------------------------------------------------------------------------------------
<mx: DataGrid id = "body"x = "188"y = "232" > <mx: columns > <mx: DataGridColumn dataField = "username" / ><mx: DataGridColumn dataField = "password" / ></mx:columns>
</mx: DataGrid >
----------------------------------------------------------------------------------------------------------------------------------------------------------
如果要使用分页效果,则必须使用标签"PrintAdvancedDataGrid" (Flex3中的标签)才能够实现分页效果
private
function doPrint() : void {
var PrintJob: FlexPrintJob = new FlexPrintJob();
if (PrintJob.start()) {
addChild(body);
//设置的打印视图属性
while (true) {
PrintJob.addObject(body);
if (body.validNextPage) {
body.nextPage();
} else {
break;
}
}
}
PrintJob.send();
}
这个方法,所对应的标签是:
< mx: PrintAdvancedDataGrid id = "body"x = "188"y = "232" > <mx: columns > <mx: AdvancedDataGridColumn dataField = "username" / ><mx: AdvancedDataGridColumn dataField = "password" / ></mx:columns>
</mx: PrintAdvancedDataGrid >
