Here’s another way you could do it: Objective-C [tableView setContentOffset:CGPointZero animated:YES]; Swift 3 and higher tableView.setContentOffset(.zero, animated: true) Probably the easiest and most straight forward way to do it.
Try this: override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { let indexPath = tableView.indexPathForSelectedRow() //optional, to get from any UIButton for example let currentCell = tableView.cellForRowAtIndexPath(indexPath) as UITableViewCell print(currentCell.textLabel!.text)
The selectedItem in the selection model is an observable property, so you should be able to achieve this with: tableview1.getSelectionModel().selectedItemProperty().addListener((obs, oldSelection, newSelection) -> { if (newSelection != null) { tableview2.getSelectionModel().clearSelection(); } }); tableview2.getSelectionModel().selectedItemProperty().addListener((obs, oldSelection, newSelection) -> { if (newSelection != null) { tableview1.getSelectionModel().clearSelection(); } });
This question is probably opinion based, so take my answer with a grain of salt, but I wouldn’t say that force downcast is always bad; you just need to consider the semantics and how that applies in a given situation. as! SomeClass is a contract, it basically says “I guarantee that this thing is an … Read more
Alignment of all table columns: Starting from JavaFX-8, you can use newly defined CSS selector table-column, #my-table .table-column { -fx-alignment: CENTER-RIGHT; } For JavaFX-2, To achieve this define a CSS selector: #my-table .table-cell { -fx-alignment: CENTER-RIGHT; /* The rest is from caspian.css */ -fx-skin: “com.sun.javafx.scene.control.skin.TableCellSkin”; -fx-padding: 0.166667em; /* 2px, plus border adds 1px */ -fx-background-color: … Read more
Changing the property selectedBackgroundView is correct and the simplest way. I use the following code to change the selection color: // set selection color UIView *myBackView = [[UIView alloc] initWithFrame:cell.frame]; myBackView.backgroundColor = [UIColor colorWithRed:1 green:1 blue:0.75 alpha:1]; cell.selectedBackgroundView = myBackView; [myBackView release];
You get this for free, but you should check that the scrollsToTop attribute of your UITableView is YES. When this does NOT work is when you have a UIScrollView (or descendant class like UITextView) object embedded inside another UIScrollView class (like UITableView). In this case, set scrollsToTop on the embedded UIScrollView class to NO. Then … Read more
First, don’t forget to extends from UICollectionViewDelegateFlowLayout delegate. For single collectionview display logic : func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { let width = ((collectionView.frame.width – 15) / 2) // 15 because of paddings print(“cell width : \(width)”) return CGSize(width: width, height: 200) } And important point in storyboard … Read more
TableView<MyType> table = new TableView<>(); //… table.setRowFactory( tv -> { TableRow<MyType> row = new TableRow<>(); row.setOnMouseClicked(event -> { if (event.getClickCount() == 2 && (! row.isEmpty()) ) { MyType rowData = row.getItem(); System.out.println(rowData); } }); return row ; }); Here is a complete working example: import java.util.Random; import java.util.function.Function; import javafx.application.Application; import javafx.beans.property.IntegerProperty; import javafx.beans.property.SimpleIntegerProperty; import … Read more
Since JavaFX 8u60 you can use(assuming tableView is an instance of TableView class): tableView.refresh(); From the documentation: Calling refresh() forces the TableView control to recreate and repopulate the cells necessary to populate the visual bounds of the control. In other words, this forces the TableView to update what it is showing to the user. This … Read more
