把一個標籤放在python gtk文本條目旁邊

所以我試圖用python GTK構建一個非常基本的GUI，但我很快就感到沮喪。如何將我的標籤放在我的文字輸入旁邊？我怎樣才能讓這個項目更小？按鈕更小？我將不得不添加更多條目，並一次性全部處理這些信息，而且我不一定需要它們填滿窗口......謝謝。把一個標籤放在python gtk文本條目旁邊

嘗試使用Table，並使用表添加到窗口：

table=Gtk.Table(1,4,True) 
table.attach(label,0,1,0,1) 
table.attach(entry,1,3,0,1) 
table.attach(button,3,4,0,1) 
window.add(table) 
window.show_all()

這顯示文本框旁邊的標籤，與按鈕旁邊它

「這顯示了文本旁邊的標籤bo [x]」所以它確實......但它將它垂直和水平居中（不需要），而我的按鈕不在哪裏可以找到......數字是多少相當於？我可以拿到我的按鈕，但它佔據了整個窗口的一面，再次，不想要。 –

這會在文本框旁邊顯示標籤，旁邊有按鈕，並且該按鈕與整個窗口一樣高。這些數字對應什麼？ –

所有這三個對象的大小將與窗口大小相同。如果要減少它，請增加行數和列數。至於數字，請參閱我發佈的鏈接 –

您可以設置hexpand和vexpand屬性爲False，halign和valign屬性爲Gtk.Align.FILL以外的其他屬性，以便這些小部件不佔用最大值空間。
