Add()的第一個(gè)參數(shù)顯然是要添加的wxWindow或wxSizer。第二個(gè)選項(xiàng)在文檔中以“option”的形式出現(xiàn)，但是用“proportion”可能更好。這個(gè)參數(shù)定義了sizer的子元素之間的大小關(guān)系。在一個(gè)垂直大小，這改變高度;在水平sizer中，這會(huì)改變寬度。

wxBoxSizer *sizer = new wxBoxSizer(wxVERTICAL); // Second button is three times as tall as first button sizer->Add(new wxButton(this, -1, "A Really Really Big Button"), 1, 0, 0); sizer->Add(new wxButton(this, -1, "Tiny Button"), 3, 0, 0); sizer->SetSizeHints(this); SetSizer(sizer);

button高度為6:3:12
