[英]Java's SWT: How to properly set GUI components?
I'm trying to create a gui for chess game and could use some help. 我正在尝试为国际象棋游戏创建GUI,可以使用一些帮助。
I set up two panels: left panel, and right panel (both seats on a main panel). 我设置了两个面板:左面板和右面板(两个都位于主面板上)。 the left panel will contain the chess board itself, and the right panel will contain some more widgets.
左侧面板将包含棋盘本身,右侧面板将包含更多小部件。
The problem is, I just can get the right panel to be positioned at the right side of the window. 问题是,我只需要将正确的面板放在窗口的右侧即可。
So to give you first some more background, here's how I want it to look: 因此,首先给您一些背景知识,这就是我希望它看起来的样子:
and here's how it looks: 外观如下:
I tried to set the main panel (the one that holds both the left and the right panels) with FormLayout() object and then to set: 我尝试使用FormLayout()对象设置主面板(同时包含左右面板的面板),然后进行设置:
FormData form_data=new FormData();
form_data.left=new FormAttachment(left_panel);
right_panel.setLayoutData(form_data);
but that didn't do anything. 但这什么也没做。
Here's the relevant code: 以下是相关代码:
shell=new Shell(display,SWT.DIALOG_TRIM);
shell.setText("Chess");
/*********************
* setting main panel
*********************/
Composite main_panel=new Composite(shell, SWT.NONE);
main_panel.setBackgroundImage(background); //size of this image is 800x650, which means it should encompass the left and right panels exactly
main_panel.setBackgroundMode(SWT.INHERIT_DEFAULT);
main_panel.setBounds(background.getBounds());
main_panel.setLayout(new GridLayout(2,false);
/*********************
* setting left panel
*********************/
left_panel=new Composite(main_panel, SWT.NONE);
GridData data=new GridData(SWT.FILL, SWT.FILL, false, true);
data.widthHint = 650;
left_panel.setLayoutData(data);
board_panel=new Composite(left_panel,SWT.NONE);
board_panel.setBackgroundImage(game_board); //size of this image is 520x520
board_panel.setLocation(65, 65); //board size is 520x520, so this centralizes it in left panel
/*********************
* setting right panel
*********************/
right_panel=new Composite(main_panel, SWT.NONE);
right_panel.setBackgroundImage(panel); //size of this image is 150x650
right_panel.setLayoutData(new GridData(SWT.END, SWT.FILL, true, true));
shell.pack();
BTW, what style should I set the Composite to, if I don't anything special in it? 顺便说一句,如果我没有什么特别的建议,应该将Composite设置为哪种样式?
(as you can see I set it to SWT.NO_RADIO_GROUP because I didn't know what to put there...) (如您所见,我将其设置为SWT.NO_RADIO_GROUP,因为我不知道该放在那里...)
Any help would greatly appreciated. 任何帮助将不胜感激。

Never ever use setBounds
unless absolutely necessary. 除非绝对必要,否则切勿使用
setBounds
。 Use a Layout
instead. 请改用
Layout
。
Here is an excellent tutorial about layouts. 这是有关布局的出色教程。
Here is some example code that should give you a starting point: 这是一些示例代码,应该为您提供一个起点:
public static void main(String[] args)
{
final Display display = new Display();
Shell shell = new Shell(display);
shell.setText("StackOverflow");
shell.setLayout(new GridLayout(2, false));
Composite chessBoard = new Composite(shell, SWT.BORDER);
chessBoard.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
Composite settings = new Composite(shell, SWT.BORDER);
GridData data = new GridData(SWT.END, SWT.FILL, false, true);
data.widthHint = 100;
settings.setLayoutData(data);
shell.pack();
shell.open();
shell.setSize(400, 200);
while (!shell.isDisposed())
{
if (!display.readAndDispatch())
display.sleep();
}
}
