tableview

问题 I am getting a strange error with iOS13 when performing a Segue and I can't figure out what it means, nor can I find any documentation for this error. The problem is that this seems to cause a lot of lag (a few seconds) until the segue is performed. 2019-09-11 22:45:38.861982+0100 Thrive[2324:414597] [TableView] Warning once only: UITableView was told to layout its visible cells and other contents without being in the view hierarchy (the table view or one of its superviews has not been added

问题 TableColumn tc = new TableColumn(); tc.getStyleClass.add(".style in css file") I set up the TableColumn with a CSS file, and I want to give each cell different background colors.

问题 I've searched all over and have been trying for a few weeks now (and even bought a few books.. unheard of) to have a segmented control work which allows for switching between the mapview and a tableview. Basically I'm using parsed data from xml to get the locations of stores (say trader joes) and I'm able to get the locations to come onto the mapview successfully. But I've no idea how to pass the parsed data to a tableview. I'm quite frustrated as this seems to be a relatively popular design

问题 After messing around with Netbeans and Scenebuilder for a while I'm stuck at a problem I can't quite understand. I use a custom cellfactory to bind a doubleclick event to the cells in my tableview. But when I set the cellfactory and a cellValueFactory only the custom cellFactory has an effect. I'm trying to populate a tableview with data from a number of objects and bind a double click event to the cells of the first column. Populating is not the problem, I just used idNumber

问题 I'd like to run the code [tableView reloadData], except I want to call it from a seperate class to the view controller I want to reload the data in. (Note. If there is something more effective to reload a tableview than reloadData, chime in). Say the view I want to reload is 'RootViewController', and I am currently in 'DetailViewController', what do i need to do to make it work. My best attempt right now is [RootViewController.tableView reloadData], but its not right. (I get error: expected '

问题 I've been debugging my iphone app and found something interesting. I have a UIViewControllers with TabBarcontroller( 6 tabs). Each tab is a UIViewController and it has a UITtableview. The viewDidLoad works and brings the initial data. On of the UITableView has a search bar. After the user touchs presses search some magic happens and I get an array with data. I cant see the new data in the tableview and the [tableView reloadData] has no effect outside viewDidLoad (first time). I can see the

问题 I tried to populate a tableView , I followed the tutorial given in docs.oracle, but in my table there are Integer fields, so I do the same thing to add them. The code in the information class (like Person class): private SimpleIntegerProperty gel; public int getGel() { return gel.get(); } public void setGel(int pop) { gel.set(pop); } The code in the Main class: TableColumn gel = new TableColumn("Gel"); gel.setMinWidth(100); gel.setCellValueFactory(new PropertyValueFactory<Information, Integer

问题 I have a SQLite 3 database with 4 columns and QML code with TableView that displays it: TableView { id: table ...
