JavaFX: optimal width of TextFlow with word-wrap

由 无人久伴 提交于 2019-12-06 06:15:17
With Textflow.setMaxWidth(double) I can achieve text wrapping. But how can I adjust the width of TextFlow afterwards so that it is based on the actual wrapping position? In other words, how to let the TextFlow bounds snap to all of its children Text bounds to get rid of the empty space on the right: **Edit** I have made some progress on this issue. My class derived from TextFlow now contains: double maxChildWidth = 0; for (Node child : getManagedChildren()) { double childWidth = child.getLayoutBounds().getWidth(); maxChildWidth = Math.max(maxChildWidth, childWidth); } double insetWidth =

How to detect location and size of tab header in JavaFX

由 北慕城南 提交于 2019-12-06 06:05:59
I am still new to javaFX. In my code I need to get location and size of tab header, but I can't find any property or function which return its size or location.

由 僤鯓⒐⒋嵵緔 提交于 2019-12-06 05:48:45
问题 I have a TreeTableView where every node has an icon. Everything works perfectly when I expand the tree, but when I collapse the tree, the icons of the no longer visible items are left behind. The rows and the text are removed, but the icons remain "free-floating". In the screenshot you can see the TreeTableView twice, once expanded with the correct text, and once collapsed with only the remaining icons. The screenshot above was created from the following minimal example (you just need to add

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-06 04:14:29
问题 after having spent the last few hours searching the web for this issue I decided that I need your help. The issue is similar to this topic: Javafx: Tableview header is not aligned with rows No answer has been provided there and also, I think, my case is slightly different: I have a properly setup TableView with reused CellFactories and CellValueFactories. Data-wise, everything works 100% the way I intended. However once I populated my table with more rows than my view can show it naturally
