问题 I have a JScrollPane containing a JPanel. I fill this JPanel with many buttons. Is there any possibility to get the currently shown buttons? I know I can access the children of a JPanel via jpanel.getComponents() but those are all components in this pane; I want only the ones that are currently on screen. 回答1: I assume that this container is already visible on the screen, then I suggest 1) to extract JViewPort from JScrollPane, 2) addChangeListener to JViewPort 3) each visible JComponent(s)

JavaFX - Zoom relative to mouse position

I can't get working zoom relative to mouse position in JavaFX. I've read and tried rewrite this and this , but it's not working. Can't scroll viewport using scrollPane.setViewportBounds() . I must use scrollPane.setHvalue() and scrollPane.setVvalue() , but can't get right recalculation to keep the same pixels under the mouse cursor. Current code keeps scrollbars positions: ZoomHandler.java import javafx.event.EventHandler; import javafx.scene.control.ScrollPane; import javafx.scene.input.ScrollEvent; import javafx.scene.layout.Pane; public class ZoomHandler implements EventHandler<ScrollEvent>

JavaFX 2: Making a ScrollPane automatically scroll to the edge after adding content

由 纵然是瞬间 提交于 2019-12-04 13:59:58
问题 Using JavaFX 2, I have a basic example of a ScrollPane that contains an HBox of Label s. I want to be able to add a Label to the HBox , and simultaneously scroll to the right edge of the ScrollPane so that the newly added Label is visible. My current method uses the setHvalue() to set the scroll position and getHmax() to get the maximum scrolling distance allowed. The problem is that when I set the scroll position using getHmax() , it is as if the just-added Label is not computed in the

问题 So I am creating a map in JavaFX and I would like to have the whole map visible at times.

Below is the code that I have written. package gameaspects; import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import javafx.application.Application; import javafx.scene.Scene; import javafx

Sizing a JScrollPane in a JTabbedPane in a JFrame

I understand from this post Don't Set sizes on a JComponent that you dont set preferred sizes on any component and instead let the layout manager do this for you. My question is, I have a JPanel that I put into a JTabbedPane into a JFrame like this JFrame frame=new JFrame(); JTabbedPane pane=new JTabbedPane(); pane.addTab("Tab 1",new JScrollPane(getJPanel1())); pane.addTab("Tab 2",new JScrollPane(getJPanel2())); frame.setContentPane(pane); Now in this case the JTabbedPane will take the size of the maximum sized component you add to it. Because of this my JScrollPane does not show up at all. I
