我將TreeView放置爲ScrollPane的內容。 ScrollPane放置在SplitPane中。 當我拖動SplitPane的分隔線,使其變得比TreeView大小更大時,我會看到TreeView的邊框。 我希望TreeView能夠在拖動SplitPane的分隔符後調整空間大小。我的代碼:如何使TreeView的調整大小與父ScrollPane一樣多?
SplitPane splitPane = new SplitPane();
splitPane.getItems().addAll(createTreeOfConnections());
private ScrollPane createTreeOfConnections() {
ScrollPane scrollPane = new ScrollPane();
scrollPane.setMinSize(100, 300);
scrollPane.setPrefSize(200, 500);
scrollPane.setMaxSize(Double.MAX_VALUE, Double.MAX_VALUE);
scrollPane.setVbarPolicy(ScrollBarPolicy.AS_NEEDED);
scrollPane.setHbarPolicy(ScrollBarPolicy.AS_NEEDED);
scrollPane.setContent(new ConnectionsTree(this));
return scrollPane;
類ConnectionsTree擴展TreeView和它的構造是:
public ConnectionsTree(MainStage mainStage) {
// here we set the root of ConnectionsTree which is not visible
super();
this.mainStage = mainStage;
root = new ConnectionTreeItem();
root.setExpanded(true);
super.setRoot(root);
super.setShowRoot(false);
super.setEditable(false);
super.getSelectionModel().setSelectionMode(SelectionMode.SINGLE);
super.setMaxSize(Double.MAX_VALUE, Double.MAX_VALUE);
retrieveExistentConnectionsNodes();
ContextMenu contextMenu = new ContextMenu(createNewConnectionMenuItem(
"New Connection", KeyCombination.valueOf("Ctrl+N")));
super.setContextMenu(contextMenu); }
如何判斷TreeView控件(我TreeConnections),它應該採取SplitPane的左邊部分的所有可用空間?
謝謝!
問題是,我把樹視圖到滾動窗格。但是TreeView在內部有scrollPane,在需要時顯示。將TreeView放入SplitPane後,它工作正常。 –
@VolodymyrLevytskyi謝謝!我也解決了它。 –
