Question

我正在尝试让Guake终端在Unity中正常工作。它的窗口宽度等于屏幕宽度。但由于Unity左侧酒吧窗口的右边界变得无形。所以，我想为窗口设置合适的宽度。它必须小于实际窗口大小。无论是否使用Unity，代码都必须正常工作。

这就是Guake如何确定其窗口的位置和大小：

def get_final_window_rect(self):

    """Gets the final size of the main window of guake. The height
    is the window_height property, width is window_width and the
    horizontal alignment is given by window_alignment.
    """
    screen = self.window.get_screen()
    height = self.client.get_int(KEY('/general/window_height'))
    width = 100
    halignment = self.client.get_int(KEY('/general/window_halignment'))

    # get the rectangle just from the first/default monitor in the
    # future we might create a field to select which monitor you
    # wanna use
    window_rect = screen.get_monitor_geometry(0)
    total_width = window_rect.width
    window_rect.height = window_rect.height * height / 100
    window_rect.width = window_rect.width * width / 100

    if width < total_width:
        if halignment == ALIGN_CENTER:
            window_rect.x = (total_width - window_rect.width) / 2
        elif halignment == ALIGN_LEFT:
            window_rect.x = 0
        elif halignment == ALIGN_RIGHT:
            window_rect.x = total_width - window_rect.width
    window_rect.y = 0
    window_rect.width = 250
    return window_rect

所以你想从你的total_width中减去unity启动器的宽度。可以使用gconf确定此大小以获取启动器图标的值：

self.client.get_int('/apps/compiz-1/plugins/unityshell/screen0/options/icon_size')

当然你也想知道当前正在运行的会话是否确实是统一的：

os.environ.get('DESKTOP_SESSION')  == 'ubuntu'

似乎是一个很好的解决方案。（http://stackoverflow.com/questions/2035657/what-is-my-current-desktop-environment）
