阅读更多关于 Showing texts over the face of a Box based on the visible area on zooming in/out

问题 I have a sample 3D application (built by taking reference from the Javafx sample 3DViewer) which has a table created by laying out Boxes and Panes: The table is centered wrt (0,0,0) coordinates and camera is at -z position initially. It has the zoom-in/out based on the camera z position from the object. On zooming in/out the object's boundsInParent increases/decreases i.e. area of the face increases/decreases. So the idea is to put more text when we have more area (always confining within the

阅读更多关于 javafx-TableView as combobox popup (Tried and able to achieve partially. need help further)

JavaFX popup hidden when stage is in fullscreen mode

阅读更多关于 JavaFX popup hidden when stage is in fullscreen mode

I am trying to popup a dialog over my fullscreen primary stage in javafx. When I create my popup, it is unexpectedly hidden behind my fullscreen primary stage until the stage is removed from fullscreen mode (via ESC ). If I make my primary stage maximized and undecorated instead of fullscreen, then my popup will appear on top of the primary stage as expected. Am I missing something about how fullscreen mode is different than maximized and undecorated mode? Am I using fullscreen mode improperly? I am using java version 1.8.0_20 on CentOS 6.5 with Gnome. Here is my SSCCE: import javafx

阅读更多关于 Create a framework type column header for select all in JavaFX 8

问题 I am looking to create a custom TableColumn which is a CheckBox control which represents if the row is selected or not. We don't want to use the standard SHIFT or CONTROL + CLICK to handle this as users tend to click inadvertantly and lose their selection. What I would like to do is the following: In this case the column should not be part of the underlying data model, and simply represent what is selected or not. It shouldn't be dependent on the data model in any way. If the user selects the
