gtk - 使 GTK 输入框更小

Question

我正在尝试使用 Gtk 在 Julia 中制作一个 GUI 程序。我的程序包括大量的 GtkEntry 框。但是，我遇到了空间问题，因为条目框在实际字符周围有很多内部填充。我想至少减少顶部和底部的空白。我曾尝试使用 setproperty!()函数更改 height-request值(value)，但这似乎只能使盒子更大，而不是更小。此外，margin , margin-top等字段默认都设置为0。同样，我可以使它们变大但不能变小。

这有可能解决吗？我在下面包含了一个最小的工作示例、一个屏幕截图和一个显示可用属性的 Julia REPL 输出。

编辑:
我也尝试使用带有内容的 css 文件 (test.css)

entry {
  margin-top: 0;
  margin-bottom: 0;
  padding-top: 0;
  padding-bottom: 0;
}

Julia 0.6.0 代码:

using Gtk

win = GtkWindow("Example")

sb = GtkGrid()
function sb_entry(label)
    frame = GtkFrame(label)
    entry = GtkEntry()
    setproperty!(entry, :input_purpose, 2)
    push!(frame, entry)
    return frame
end
sb_rows = sb_entry("rows")
sb_cols = sb_entry("cols")
sb_row_off = sb_entry("row off")
sb_col_off = sb_entry("col off")
sb[1,1] = sb_rows
sb[2,1] = sb_cols
sb[1,2] = sb_row_off
sb[2,2] = sb_col_off
setproperty!(sb, :column_homogeneous, true)
setproperty!(sb, :column_spacing, 5)
setproperty!(sb, :row_spacing, 5)

push!(win, sb)

### begin edit (css)

screen   = Gtk.GAccessor.screen(win)
provider = GtkCssProviderLeaf(filename="/path/to/test.css")

ccall((:gtk_style_context_add_provider_for_screen, Gtk.libgtk), Void,
        (Ptr{Void}, Ptr{GObject}, Cuint),
        screen, provider, 1)

### end edit (css)

showall(win)

if !isinteractive()
    c = Condition()
    signal_connect(win, :destroy) do widget
        notify(c)
    end
    wait(c)
end

Answer 1

entry { min-height: 0px; }允许它尽可能小。根据需要调整大小。
