Xubuntu 面板中的透明按钮

Question

我想删除 XFCE 面板内按钮后面的颜色。

我尝试修改文件/usr/share/themes/Greybird/gtk-2.0/apps/xfce-panel.rc，但按钮后面出现了奇怪的白色。我想让它透明。

我想我只需要处理这部分代码：

   style "window-buttons" = "theme-panel"
   {
        xthickness      = 3
        ythickness      = 3

        bg[ACTIVE]      = @bg_color_dark
        bg[PRELIGHT]    = @bg_color_dark
        bg[SELECTED]    = @bg_color_dark

        fg[NORMAL]      = @bg_color_dark
        fg[ACTIVE]      = @bg_color_dark
        fg[PRELIGHT]    = @bg_color_dark

        engine "murrine" {
                contrast = 0.0
                gradient_shades = { 1.0, 0.9, 0.8, 0.7 }
                roundness       = 0.5
                reliefstyle     = 0
                textstyle       = 1
                text_shade      = 0.2
        }
    }

我应该修改什么？

Answer 1

无需编辑文件。

首先，确保在设置中启用了合成器（主菜单 >> 设置 >> 窗口管理器调整 >> 合成器）。

然后，右键单击面板，打开面板的首选项，打开选项卡外貌，将不透明度设置为 0。

最后，打开窗口按钮插件设置，然后取消选中显示扁平按钮。

欲了解更多信息，请阅读面板首选项对话框。

操作系统 UbuntuStudio 15.10 x386

这对我有用。创建一个文件~/.gtkrc-2.0并保存以下内容：

style "xfcepanel"
{
xthickness = 0 # from here until "Modd 10" is not relevant for this forum thread...
ythickness = 0
GtkButton::inner-border = {3,1,1,1}
#XfcePanelWindow::autohide-size = 1
font_name = "Modd 10" # ...but i left it here to show how these things work.
engine "pixmap" {
        image {
            function    = BOX
            recolorable    = TRUE
            state        = NORMAL
            }
        image {
            function    = BOX
            recolorable    = TRUE
            state        = PRELIGHT
            file        = "Panel/panel-button-hover.png"
            border        = { 3, 1, 1, 1 }
            stretch        = TRUE
            }
        image {
            function    = BOX
            recolorable    = TRUE
            state        = ACTIVE
            file        = "Panel/panel-button-active.png"
            border        = { 3, 1, 1, 1 }
            stretch        = TRUE
            }
        image {
            function    = BOX
            recolorable    = TRUE
            state        = SELECTED
            file        = "Panel/panel-button-active.png"
            border        = { 3, 1, 1, 1 }
            stretch        = TRUE
            }
        image {
            function    = BOX
            recolorable    = TRUE
            state        = INSENSITIVE
            }
        image {
            function    = ARROW
            recolorable    = TRUE
            arrow_direction    = DOWN
            }
        }
}
widget_class "XfcePanelWindow*" style "xfcepanel"

在面板 1（我添加的）中，我禁用了标签按钮：

您需要向左拖动至 Alpha 0：
