问题
As I am sure some of you are aware, I am attempting to make an alernative tool to Tiled that is open source. I asked before what layout I should use and I was suggest the MiGLayout which I really do love, but don't understand that well at all. I also hope to learn something from this as well. What I would like is someone to explain to me what I did wrong, obviously, and what I need to do to correct this.
Let me first state what works perfect in my eyes, but may not really.
- JFrame
- Menu & Menu Items
Now let me state what I don't like and is not bending to my will.
- JToolBar (There are gaps I don't want, they are circled in red)
- Both JPanels (The width it prefect, but they are not filling to the height)
My question is what can I do to fix this and how can I make the miglayout adjust so that when the toolbar is moved it doesn't make the layout fall to pieces?
Here is my code:
package main;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JPanel;
import javax.swing.JToolBar;
import javax.swing.KeyStroke;
import net.miginfocom.swing.MigLayout;
public class GUI extends JFrame {
// Window Vars //
String title;
int width;
int height;
// Mid Level componets //
JMenuBar menuBar;
JMenu file;
JToolBar toolBar;
JPanel map;
JPanel sideBar;
// Low Level componets //
JMenuItem exit;
JButton select;
public GUI(String title, int width, int height) {
this.title = title;
this.width = width;
this.height = height;
this.makeInterface();
}
public void makeInterface() {
// Setup JFrame
this.setTitle(title);
this.setSize(width, height);
this.setLocationRelativeTo(null);
this.setMinimumSize(new Dimension(700, 500));
this.setVisible(true);
this.setLayout(new MigLayout(
"debug, fillx, gap unrel rel", // Layout
"[grow, fill][fill]", // Column
"[fill][fill]")); // Row
this.makeMenu();
this.addToolBars();
this.makePanels();
this.setupActionListeners();
}
public void makeMenu() {
this.menuBar = new JMenuBar();
this.file = new JMenu("File");
this.file.setMnemonic(KeyEvent.VK_F);
this.menuBar.add(file);
this.exit = new JMenuItem("Exit", KeyEvent.VK_E);
this.exit.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_E, ActionEvent.ALT_MASK));
this.file.add(exit);
this.setJMenuBar(this.menuBar);
}
public void addToolBars() {
this.toolBar = new JToolBar("Draggable");
this.addToolBarButtons();
this.add(toolBar, "span, height 20:35:50, wrap");
}
public void addToolBarButtons() {
this.select = new JButton("Select");
this.toolBar.add(select);
}
public void makePanels() {
this.map = new JPanel();
this.sideBar = new JPanel();
this.add(map, "width 400:600:, flowy, growy");
this.add(sideBar, "width 250:300:350, flowy, growy");
}
public void setupActionListeners() {
this.exit.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
}
}
回答1:
Needed to set the sidebar and map area in the area by using the docking feature.
For example I did as follows:
this.setLayout(new MigLayout(
"fill", // Layout
"", // Column
"")); // Row
this.add(map, "width 400:600:, dock center, growy");
this.add(sideBar, "width 250:300:350, dock east, growy");
This got rid of gaps and expanded everything as needed.
