Panneaux coulissants en Java
+--+-------+-------------+ +-------+-------+--------+ | | | | | | | | | | Zone | | | | Zone | | | | | | -> | | | | | | show | | | | show | | | | | | | | | | +--+-------+-------------+ +-------+-------+--------+
J'ai obtenu un UserControl en C#, basé sur ce post. Lorsqu'un utilisateur clique sur l'un des boutons, j'ai changé le Panneau.Propriété Left, de sorte que la zone a montré des changements, en le calculant avec le bord gauche. Je veux cette fonctionnalité en java. C'est le code que j'ai fait en c#:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using TimeSheets.DataModels;
using System.Diagnostics;
namespace TimeSheets.UserControls
{
public partial class Tab : UserControl, TabItemClickListener
{
public TabListener Listener { get; set; }
private TabItem selectedItem;
private DateTime startTime;
public int ItemHeight { get; set; }
public int ItemWidth { get; set; }
public TabItem SelectedItem
{
get { return selectedItem; }
set
{
if (value != null)
{
selectedItem = value;
selectedIndex = panel.Controls.GetChildIndex(value, false);
CambiarSeleccion(selectedIndex);
}
}
}
private int selectedIndex;
public int SelectedIndex
{
get { return selectedIndex; }
set
{
selectedIndex = value;
if (selectedIndex >= 0 && selectedIndex <= panel.Controls.Count && panel.Controls.Count != 0)
CambiarSeleccion(selectedIndex);
}
}
public Tab()
{
InitializeComponent();
panel.Height = this.Height;
}
public void AddTabItem(TabItem item)
{
item.SetWidth(ItemWidth);
item.SetHeight(ItemHeight);
item.handler = this;
panel.Width += ItemWidth;
panel.Width += 6;
panel.Controls.Add(item);
}
public void LimpiarPaneles()
{
panel.Controls.Clear();
}
public TabItem GetTabItem(int position)
{
return (TabItem)panel.Controls[position];
}
public Object GetValueAt(int position)
{
if (selectedIndex >= 0 && selectedIndex <= panel.Controls.Count && panel.Controls.Count != 0)
return ((TabItem)panel.Controls[position]).Value;
else
return null;
}
private void tLeft_Tick(object sender, EventArgs e)
{
if (panel.Left < 0)
{
panel.Left = panel.Left + 5;
}
}
private void tRight_Tick(object sender, EventArgs e)
{
//Debug.WriteLine(panel.Width + "panel.Right" + panel.Right + "this.Left" + panel.Left + "panel1.Width" + panel1.Width);
if (panel.Width >= Math.Abs(panel.Left) + panel1.Width)
{
panel.Left = panel.Left - 5;
}
}
private void bRight_MouseUp(object sender, MouseEventArgs e)
{
tRight.Stop();
}
private void bRight_MouseDown(object sender, MouseEventArgs e)
{
startTime = DateTime.Now;
tRight.Start();
}
private void bLeft_MouseUp(object sender, MouseEventArgs e)
{
tLeft.Stop();
}
private void bLeft_MouseDown(object sender, MouseEventArgs e)
{
startTime = DateTime.Now;
tLeft.Start();
}
public new void Click(TabItem item)
{
selectedIndex = panel.Controls.GetChildIndex(item, false);
panel.Left = -selectedIndex * (ItemWidth + 6);
CambiarSeleccion(selectedIndex);
}
private void CallListener()
{
if (Listener != null)
Listener.OnItemSelected(selectedIndex);
}
private void bRight_Click(object sender, EventArgs e)
{
if ((DateTime.Now - startTime).Milliseconds <= 150)
{
if (selectedIndex < panel.Controls.Count - 1)
selectedIndex++;
CambiarSeleccion(selectedIndex);
}
}
private void bLeft_Click(object sender, EventArgs e)
{
if ((DateTime.Now - startTime).Milliseconds <= 150)
{
if (selectedIndex > 0)
selectedIndex--;
CambiarSeleccion(selectedIndex);
}
}
private void CambiarSeleccion(int newIndex)
{
if (selectedIndex >= 0 && selectedIndex <= panel.Controls.Count || panel.Controls.Count != 0)
{
if (selectedItem != null)
selectedItem.Deseleccionar();
CallListener();
selectedItem = GetTabItem(selectedIndex);
selectedItem.Seleccionar();
panel.Left = -selectedIndex * (ItemWidth + 6) - 2;
}
}
public void SetActivado(bool activo)
{
bLeft.Enabled = activo;
bRight.Enabled = activo;
}
}
public interface TabListener
{
void OnItemSelected(int selected);
}
}
Maintenant, je veux le traduire en Java. J'ai tout fait, mais je ne trouve pas quelque chose comme la propriété Left pour l'utiliser. Est-il quelque chose que j'ai raté?

Swing utilise des gestionnaires de mise en page pour placer un JPanel dans son composant contenant. Bien que découragé , vous pouvez désactiver l'utilisation des gestionnaires de mise en page dans un composant en le définissant sur null. Si vous le faites, vous pouvez définir manuellement les limites du JPanels.
JPanel movingPanel, containingPanel;
/* initialize movingPanel and containingPanel
... */
containingPanel.setLayout(null);
movingPanel.setBounds(yourPanelDotLeft, up, width, heigth);
Exemple avec quelques panneaux arbitraires:
import javax.swing.*;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class SlidingControl {
Frame frame = new Frame("Sliding Control");
JPanel left = new JPanel(), right = new JPanel(), middle = new JPanel();
public static void main(String[] args) {
SlidingControl application = new SlidingControl();
application.movePanels();
}
public SlidingControl() {
frame.setSize(600, 200);
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
frame.setResizable(false);
frame.setVisible(true);
initializePanels();
}
private void initializePanels(){
frame.setLayout(null);
frame.add(left);
frame.add(middle);
frame.add(right);
left.setBackground(new Color(1f, 0f, 0f));
middle.setBackground(new Color(0f, 1f, 0f));
right.setBackground(new Color(0f, 0f, 1f));
left.setBounds(10, 10, 50, 100);
middle.setBounds(400, 50, 50, 200);
right.setBounds(500, 50, 50, 200);
}
public void movePanels(){
while(true){
left.setBounds(left.getBounds().x - 5, left.getBounds().y, left.getBounds().width, left.getBounds().height);
middle.setBounds(middle.getBounds().x - 5, middle.getBounds().y, middle.getBounds().width, middle.getBounds().height);
right.setBounds(right.getBounds().x - 5, right.getBounds().y, right.getBounds().width, right.getBounds().height);
try{
Thread.sleep(600);
}catch (InterruptedException e){
e.printStackTrace();
}
}
}
}

Enfin, je l'ai fait fonctionner, mon Jpanel personnalisé a deux boutons à l'ouest et à l'est, un panneau de disposition null au centre et un panneau de disposition de flux à l'intérieur du premier panneau. Lorsque j'appuie sur la souris, il démarre la diapositive, pour afficher les DataTabItems (Juste un autre panneau avec un bouton). L'objectif de cette classe est de sélectionner un élément dans la liste et d'afficher quelque chose n'importe où.
Ceci est le code de DataTab:
/*

public class DataTab extends javax.swing.JPanel {
private final Timer tLeft = new Timer(6, (e) -> {
if (DataTab.this.tabContainer.getX() < 0)
left(5);
System.out.println("left" + DataTab.this.tabContainer.getX());
});
private final Timer tRight = new Timer(6, (e) -> {
if (DataTab.this.tabContainer.getWidth() >= Math.abs(DataTab.this.tabContainer.getX()) + DataTab.this.panel.getWidth())
left(-5);
System.out.println("right" + DataTab.this.tabContainer.getX());
});
private Data[] data;
/**

public DataTab() {

}
public void setData(Data[] data) {
this.data = data;

}
private void generateTabItems() {

for (Data d : data) {
DataTabItem item = new DataTabItem(d, 275, 275);
tabContainer.add(item);
tabContainer.setSize(tabContainer.getWidth() + item.getPreferredSize().width + 10, tabContainer.getHeight());
System.out.println(tabContainer.getComponentCount() + " " + item.getSize());
}
this.updateUI();
}
