A little example there: tableView.setRowFactory(new Callback<TableView<Data_type>, TableRow<Data_type>>(){ //There can define some colors. int

问题 Goodevening everyone, I stumbled on a rather strange problem today and I have no clue what I'm doing wrong. It's about binding table columns with a PropertyValueFactory. I created the table view and table columns in FXML and set the appropriate fx:id's with Scene Builder. Now the problem is that some columns are showing the expected data and other columns are just empty. I add the items to the table view with following code when a user presses a button: ObservableList<User> olUsers = DA_User

问题 I'm replacing the javafx context menus of a table's columns. The context menu will give the user access to excel like filtering of the table view. Everything is working, but i now wan't to open the context menu on any mouse click event on the column header. Not just the standard right click. The problem hereby is, that you can only get the header node by a lookupAll() inside the parent tableview. Due to the fact, that a lookup is only possible after the table view has been rendered, i call

问题 These are my table columns Course and Description . If one clicks on a row (the row becomes 'active'/highlighted), and they press the Delete button it should remove that row, how do I do this? The code for my Course column: (and what event listener do I add to my delete button?) @SuppressWarnings("rawtypes") TableColumn courseCol = new TableColumn("Course"); courseCol.setMinWidth(300); courseCol.setCellValueFactory(new PropertyValueFactory<Courses, String>("firstName")); final Button

问题 I am trying to get the table cells to show the string when i create new rows. But all the rows are just empty. Do anyone know what i am doing wrong?

问题 Assume that we have a simple Tableview with 3 columns (A, B, C). Each Column contains some data which is not important at the moment. I wondered if it would be possible to make only a whole column selectable (no matter where the user clicks in the column) and retrieve the ID and/or index of that column selected by the user? For example, the user clicks somewhere in the area of column B. In that case the whole column should be marked and index 2 should be returned. Any help would be

问题 I have 2 tables 'A' and 'B'. Both have a common column 'name' and linked with each other by a column 'id'. The column 'name' in the table A is empty whereas it has data in table B. My task is to fill all the data in that column from table B to table A with corresponding ids. I'm using the following query: UPDATE A SET A.name = (SELECT B.name from B WHERE A.id = B.id) WHERE EXISTS (SELECT B.name from B) As soon as I run the query in SQL developer, it just freezes and i have to force close it.

问题 I have a TableView with a number of columns that exceeds the screen width. When it's loaded the first time, all columns have the same width but, as soon as I move one of these, all of them are resized to a width equals to the maximum width of data inside the cells of the column. My question is: is it possible to disable this behavior or to make it works till the first load of the TableView? PS: the TableView is loaded empty, then pressing a button it is filled with data, because you have some
