JavaFX在多个页面上打印tableview

所以，我的问题是我需要打印我的tableview的内容，但我有很多项目，它只打印其中的前23个。 我已经在这里找到了一些解决方案，遗憾的是它们并没有多大帮助。

这是我的打印方法：

@FXML private void printIt() { Printer printer = Printer.getDefaultPrinter(); PageLayout pageLayout = printer.createPageLayout(Paper.A4, PageOrientation.LANDSCAPE, Printer.MarginType.DEFAULT); double scaleX = pageLayout.getPrintableWidth() / logBookTable.getBoundsInParent().getWidth(); double scaleY = pageLayout.getPrintableHeight() / logBookTable.getBoundsInParent().getHeight(); logBookTable.getTransforms().add(new Scale(scaleX, scaleY)); PrinterJob job = PrinterJob.createPrinterJob(); if (job != null) { boolean successPrintDialog = job.showPrintDialog(dialogStage); if(successPrintDialog){ boolean success = job.printPage(pageLayout,logBookTable); if (success) { job.endJob(); } } } }

在我能够得出答案之前，我浏览了很多post。 关键是扩展tableview的高度以显示，而无需在屏幕右侧滚动。 （有一些方法可以做到这一点而不会扭曲你的程序布局。我没有在这个问题中解决那个部分。关于如何完成这个任务有很好的答案。）一旦你将tableview的高度扩展到show all all它的行不需要滚动条。 然后只需要从零高度开始一次打印一页到一页的负高度。（在这种情况下：接近11英寸向下。边框在这里起作用。）下一页应该在最后一页找到页面结束并打印到近11英寸。 （从大约-11英寸到大约-22英寸。）这种模式一直持续到遍历了tableview的整个高度。

  Printer printer = Printer.getDefaultPrinter(); //get the default printer javafx.print.PageLayout pageLayout = printer.createPageLayout(Paper.NA_LETTER, PageOrientation.PORTRAIT, Printer.MarginType.DEFAULT); //create a pagelayout. I used Paper.NA_LETTER for a standard 8.5 x 11 in page. PrinterJob job = PrinterJob.createPrinterJob();//create a printer job if(job.showPrintDialog(taMain.getScene().getWindow()))// this is very useful it allows you to save the file as a pdf instead using all of your printer's paper. A dialog box pops up, allowing you to change the "name" option from your default printer to Adobe pdf. { double pagePrintableWidth = pageLayout.getPrintableWidth(); //this should be 8.5 inches for this page layout. double pagePrintableHeight = pageLayout.getPrintableHeight();// this should be 11 inches for this page layout. tblvMain.prefHeightProperty().bind(Bindings.size(tblvMain.getItems()).multiply(35));// If your cells' rows are variable size you add the .multiply and play with the input value until your output is close to what you want. If your cells' rows are the same height, I think you can use .multiply(1). This changes the height of your tableView to show all rows in the table. tblvMain.minHeightProperty().bind(tblvMain.prefHeightProperty());//You can probably play with this to see if it's really needed. Comment it out to find out. tblvMain.maxHeightProperty().bind(tblvMain.prefHeightProperty());//You can probably play with this to see if it' really needed. Comment it out to find out. double scaleX = pagePrintableWidth / tblvMain.getBoundsInParent().getWidth();//scaling down so that the printing width fits within the paper's width bound. double scaleY = scaleX; //scaling the height using the same scale as the width. This allows the writing and the images to maintain their scale, or not look skewed. double localScale = scaleX; //not really needed since everything is scaled down at the same ratio. scaleX is used thoughout the program to scale the print out. double numberOfPages = Math.ceil((tblvMain.getPrefHeight() * localScale) / pagePrintableHeight);//used to figure out the number of pages that will be printed. //System.out.println("pref Height: " + tblvMain.getPrefHeight()); //System.out.println("number of pages: " + numberOfPages); tblvMain.getTransforms().add(new Scale(scaleX, (scaleY)));//scales the printing. Allowing the width to say within the papers width, and scales the height to do away with skewed letters and images. tblvMain.getTransforms().add(new Translate(0, 0));// starts the first print at the top left corner of the image that needs to be printed //Since the height of what needs to be printed is longer than the paper's heights we use gridTransfrom to only select the part to be printed for a given page. Translate gridTransform = new Translate(); tblvMain.getTransforms().add(gridTransform); //now we loop though the image that needs to be printed and we only print a subimage of the full image. //for example: In the first loop we only pint the printable image from the top down to the height of a standard piece of paper. Then we print starting from were the last printed page ended down to the height of the next page. This happens until all of the pages are printed. // first page prints from 0 height to -11 inches height, Second page prints from -11 inches height to -22 inches height, etc. for(int i = 0; i < numberOfPages; i++) { gridTransform.setY(-i * (pagePrintableHeight / localScale)); job.printPage(pageLayout, tblvMain); } job.endJob();//finally end the printing job.

自己找到了解决方案

1）创建for循环

2）创建新表并插入未打印的项目

3）打印
