[英]Waiting for a button to be pressed in Java Swing before moving on?
所以我有這個GUI
public ChangePokemonView(Controller c)
{
this.controller = c;
this.currentBattleEnvironment = currentBattleEnvironment.getInstance();
populateInactivePokemon(); //REMOVE LATER REMOVE LATER REMOVE LATER REMOVE LATER REMOVE LATER
this.pokemonList = new JList(inactivePlayerPokemon);
pokemonList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); //Only one thing can be selected at a time.
this.pokemonLabel = new JLabel("Choose your Pokemon!");
this.confirmSelection = new JButton("Confirm Selection");
this.confirmSelection.addActionListener(this);
setLayout(new BorderLayout());
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Closes GUI window when close, may need to change later
JPanel centerPanel = new JPanel(new GridLayout(3, 1));
centerPanel.add(pokemonLabel);
centerPanel.add(pokemonList);
centerPanel.add(confirmSelection);
add("Center", centerPanel);
pack();
setVisible(true);
}
這只是創建一個項目列表和一個按鈕。 單擊該按鈕時,它將獲取所選項目並將其返回到控制器然后進行處理(對於我們的項目,它會更改玩家口袋妖怪)。
*/
@Override
public void actionPerformed(ActionEvent event)
{
if (event.getSource() == confirmSelection)
{
this.pokemonSelected = (String) pokemonList.getSelectedValue();
this.controller.setCurrentPokemon(this.pokemonSelected);
//JOptionPane.showConfirmDialog(null, "You pressed: "+output); //USED FOR TESTING, THIS WILL OUPUT JUST THE NAME THAT WAS SELECTED
}
}
setCurrentPokemon與控制器沒有任何關系。 我只是想確保它現在能夠得到選擇。 但是我在等待選擇的其余代碼時遇到問題。
我認為Swing和Java的輸入應該暫停並等待輸入,然后繼續使用其余的代碼。 但是,現在它運行打開選擇菜單,但然后在控制器中將選定的寵物小貓設置為null。 我想添加一個while循環來等待並解決這個問題,但我覺得有一個更容易的方法來構建Swing。
有沒有辦法,所以我可以讓我的其余代碼等到選擇按鈕並處理操作?
提前致謝。
