设置gui元素的大小和位置

Question

我已经编写了一些代码来在swi-prolog中创建GUI，但是我的主窗口对于我的所有按钮和文本字段都太小了。例如，我可以在＆＃34;第二列＆＃34;中绘制第六个函数结果，就在第一个结果的右侧？

showForm :-
    new(W,  window('Test', size(800, 800))),
    new(D, dialog('Main window', size(800, 800))),

    /* 6) serach if country is in Europe */
    new(Etiq, text_item('1) Enter country here:')),
    send(D, append, Etiq),
    new(Result, label),
    send(D, append, Result),
    send(D, append, button(search, message(@prolog, memberCountry, Etiq, Result))),


    /* 7) Path form-to (serach in deep) */
    new(Path1, text('6) Path form-to (serach in deep)')),
    new(From1, text_item('Enter country FROM here:')),
    new(To1, text_item('Enter country TO here:')),
    send(D, append, Path1),
    send(D, append, From1),
    send(D, append, To1),

    send(Path1, right, Etiq),

    new(Path1Res, label),
    send(D, append, button(path, message(@prolog, dfs, From1, To1, [], Path1Res))),
    send(D, append, Path1Res),

% .....

send(D, below, W),
    send(D, open),
    !.
