我无法在 wibox.container.scroll 内的小部件上捕获鼠标信号
I cannot catch mouse signals on widgets within a wibox.container.scroll
我正在根据 iw dev interface scan 的输出动态构建小部件，然后将它们添加到 wibox 中的滚动框。我发现的问题是 mouse::enter 和 mouse::leave 信号我连接的小部件在 wibox.container.scroll 内部时不捕获鼠标信号。如果我省略 wibox.container.scroll 包装器，所有其余代码都按预期工作并且信号按预期捕获。
要添加到滚动容器的小部件模板：
function wifitbox.new(ssid, screen, interface)
tbox = wibox.widget{
{
{
wibox.widget.textbox(ssid[2] .. " " .. ssid[3]),
{
wibox.widget.textbox(ssid[4]),
halign = "right",
widget = wibox.container.place
},
layout = wibox.layout.ratio.horizontal
},
margins = beautiful.xresources.apply_dpi(10, screen),
widget = wibox.container.margin
},
id = "tbox",
bg = beautiful.wifi_tbox_bg or "#928374",
shape = function(cr, width, height)
gears.shape.rounded_rect(cr, width, height, 5)
end,
widget = wibox.container.background
}
awful.spawn.easy_async('bash -c "sudo iw dev ' .. interface .. ' station dump | awk \'FNR == 1 {print()}\'"', function(stdout)
if(gears.string.split(stdout, "\n")[1] == ssid[1]) then
tbox.bg = "#b16286"
end
end)
tbox:connect_signal("mouse::enter", function()
tbox.bg_cache = tbox.bg
tbox.bg = "#689d6a"
end)
tbox:connect_signal("mouse::leave", function()
tbox.bg = tbox.bg_cache
end)
return tbox
end
两个 :signal_connect() 语句是问题中的语句。
小部件添加到滚动容器如下：
awful.spawn.with_line_callback(cmd, {
stdout = function(line)
local ssid = gears.string.split(line, "\t")
wifitbox_table:get_children_by_id("tbox_list")[1]:add(wifitbox(ssid, screen, interface))
end,
output_done = function()
self:set_widget(wifitbox_table)
end
})
包含滚动容器的widget如下：
local wifitbox_table = wibox.widget{
scrollbtn,
{
id = "scroll_box",
speed = 100,
extra_space = beautiful.xresources.apply_dpi(5, screen),
layout = wibox.container.scroll.vertical,
step_function = wibox.container.scroll.step_functions.linear_increase,
{
id= "tbox_list",
spacing = beautiful.xresources.apply_dpi(5, screen),
layout = wibox.layout.fixed.vertical()
}
},
spacing = beautiful.xresources.apply_dpi(5, screen),
layout = wibox.layout.fixed.vertical,
}
正如我之前提到的，如果我删除 "tbox_list" 周围的 "scroll_box" 小部件小部件信号连接没有问题。但显然我没有滚动。

The problem I find is that the mouse::enter and mouse::leave signals I connect the widgets to do not catch the mouse signals when inside the wibox.container.scroll
https://awesomewm.org/doc/api/classes/wibox.container.scroll.html上的第三句是：
Please note that mouse events do not propagate to widgets inside of the scroll container.
所以，这是“按预期工作”。
