Question

我想使用网格窗格打印多个页面。数据来自CSV文件有人建议解决方案吗？这是我用来打印它的代码有一个Grid Pane，它包含在Pane中，因为它写入的过程显示要打印的信息然后通过单击PRINT按钮将信息发送到打印机 final Printer selectedPrinter = Printer.getDefaultPrinter（）; int R = 0; @FXML private void onBuildRpt（ActionEvent e）抛出IOException {

pane.setVisible(false);
paneRpt.setVisible(true);
gpRpt.setVisible(true);
gpRpt.getChildren().clear();
//gpRpt.gridLinesVisibleProperty().set(true);
gpRpt.setLayoutX(5);
gpRpt.setLayoutY(10);

R = 2;

Text txtH1 = new Text("Hospital Number");
GridPane.setHalignment(txtH1, HPos.CENTER);
txtH1.setFont(Font.font("Times New Roman", FontWeight.BLACK, FontPosture.REGULAR, 14));
gpRpt.add(txtH1, 0, 0);

Text txtH2 = new Text("First Name");
GridPane.setHalignment(txtH2, HPos.LEFT);
txtH2.setFont(Font.font("Times New Roman", FontWeight.BLACK,
FontPosture.REGULAR, 14));    
gpRpt.add(txtH2, 1, 0);

Text txtH3 = new Text("Last Name");
GridPane.setHalignment(txtH3, HPos.LEFT);
txtH3.setFont(Font.font("Times New Roman", FontWeight.BLACK,
FontPosture.REGULAR, 14));     
gpRpt.add(txtH3, 2, 0);

Text txtH4 = new Text("Room");
GridPane.setHalignment(txtH4, HPos.LEFT);
txtH4.setFont(Font.font("Times New Roman", FontWeight.BLACK, FontPosture.REGULAR, 14));
gpRpt.add(txtH4, 3, 0);

@FXML

double lMargin = 0.25;
double rMargin = 0.25;
double tMargin = 0.25;
double bMargin = 0.25;
PageLayout pageLayout =
printer.createPageLayout(Paper.NA_LETTER,PageOrientation.PORTRAIT

，lMargin，rMargin，tmargin的，bMargin）;

JobSettings jobSettings = job.getJobSettings();
jobSettings.setPageLayout(pageLayout);

//System.out.println(jobSettings);
//boolean proceed = job.showPageSetupDialog(null);
boolean printed = job.printPage(node);
if (printed) {
// End the printer job
job.endJob();
}
pane.setVisible(true);
paneRpt.setVisible(false);

}

Answer 1

您可以尝试这样的事情：

// Get the print page size:
final double  prnW = pageLayout.getPrintableWidth();
final double  prnH = pageLayout.getPrintableHeight();

// Work out how many pages across and down are needed (This code may not work?):
final int  pagesAcross = (int) Math.ceil( gridPane.getWidth() / prnW );
final int  pagesDown = (int) Math.ceil( gridPane.getHeight() / prnH );

/* Print pages down and then across like so:
   1    3
   2    4
   Swop the for loops around if you want to print pages across first and then down.
*/
for ( int pgCol = 0; pgCol < pagesAcross; pgCol++ )
{
    for ( int pgRow = 0; pgRow < pagesDown; pgRow++ )
    {
        gridPane.setTranslateX( -(prnW * pgCol) );
        gridPane.setTranslateY( -(prnH * pgRow) );
        job.printPage( pageLayout, gridPane );
    }
}

job.endJob();

Answer 2

@James_Duh将两个TextField添加到第二个窗格（paneRpt）。然后在Scene Builder中将GridPane（gpRpt）包装在ScrollPane中，并将新列添加到GridPane列零，只需要PerfWidth 25.我重写了onBuildRpt方法，以便GridPane反映CSV文件中的所有数据。 GridPane现在可以滚动，每个记录都有一个行号。以下是有趣的开始，您现在可以选择打印的起始行号和结束行号。我无法发出换页，因此打印仍然是一个多步骤的过程。实际的打印设计由printRpt调用的新方法printRpt管理。我在下面发布了相关代码。

@FXML
private void onBuildRpt(ActionEvent e) throws IOException {

if(list.size()==0) {
Alert alert = new Alert(Alert.AlertType.WARNING);
alert.setTitle("Information");
alert.setHeaderText("");
alert.setContentText("No Data for Report\n"+
"Select File then Alt + A to Add New Data");
alert.showAndWait();
return;
}

int row = 0;
togp = new ArrayList<>();
pane.setVisible(false);
paneRpt.setVisible(true);
gpRpt.setVisible(true);
gpRpt.getChildren().clear();
//gpRpt.gridLinesVisibleProperty().set(true);
//gpRpt.setLayoutX(20);
//gpRpt.setLayoutY(10);

int R = 2;

File file = new File("C:/A_Hospital/Patients.csv");
Path dirP = Paths.get(String.valueOf(file));
InputStream in = Files.newInputStream(dirP);
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
scan = new Scanner(reader);
scan.useDelimiter("\\s*,\\s*");


while (scan.hasNext()){
String hospnum = scan.next();
String fname = scan.next();
String lname = scan.next();
String roomnum = scan.next();

togp.add(hospnum);
togp.add(fname);
togp.add(lname);
togp.add(roomnum);
}

scan.close();

for(int p = 0; p < togp.size(); p++){

row = row + 1;

Text txt0 = new Text(""+row);
//row number
GridPane.setHalignment(txt0, HPos.CENTER);
txt0.setFont(Font.font("Times New Roman", FontWeight.BLACK,
