Creates and manages a modal progress bar. This is intended to be used with coroutines, where a main UI thread controls the progress bar dialog while a background coroutine (worker thread) yields to the main thread between steps. The main thread checks the status of the button and if it’s not set, returns control to the coroutine.
The legacy (GTK+) user interface displayed this as a separate dialog, hence the “Dlg” suffix. The Qt user interface shows a progress bar inside the main status bar.
Creates and displays a new ProgDlg progress bar with a button and optional title.
It is highly recommended that you wrap code that uses a ProgDlg instance because it does not automatically close itself upon encountering an error.
Requires a GUI.
if not gui_enabled() then return end
local p = ProgDlg.new("Constructing", "tacos")
-- We have to wrap the ProgDlg code in a pcall in case some unexpected
-- error occurs.
local ok, errmsg = pcall(function()
local co = coroutine.create(
function()
local limit = 100000
for i=1,limit do
print("co", i)
coroutine.yield(i/limit, "step "..i.." of "..limit)
end
end
)
-- Whenever coroutine yields, check the status of the cancel button to determine
-- when to break. Wait up to 20 sec for coroutine to finish.
local start_time = os.time()
while coroutine.status(co) ~= 'dead' do
local elapsed = os.time() - start_time
-- Quit if cancel button pressed or 20 seconds elapsed
if p:stopped() or elapsed > 20 then
break
end
local res, val, val2 = coroutine.resume(co)
if not res or res == false then
if val then
debug(val)
end
print('coroutine error')
break
end
-- show progress in progress dialog
p:update(val, val2)
end
end)
p:close()
if not ok and errmsg then
report_failure(errmsg)
end
Arguments
- title (optional)
- Title of the progress bar. Defaults to "Progress".
- task (optional)
- Optional task name, which will be appended to the title. Defaults to the empty string ("").
Returns
The newly created ProgDlg object.

Arguments

- Progress value out of range (must be between 0.0 and 1.0)
Creates and manages a text window. The text can be read-only or editable, and buttons can be added below the text.
Creates a new TextWindow text window and displays it.
Requires a GUI.
if not gui_enabled() then return end
-- create new text window and initialize its text
local win = TextWindow.new("Log")
win:set("Hello world!")

win:add_button("Clear", function() win:clear() end)
win:add_button("Enable edit", function() win:set_editable(true) end)
-- add button to change text to uppercase
win:add_button("Uppercase", function()
local text = win:get_text()
if text ~= "" then
win:set(string.upper(text))
end
end)
-- print "closing" to stdout when the user closes the text windw
win:set_atclose(function() print("closing") end)

The color list can be set from the command line using two unofficial preferences: gui.colorized_frame.bg and gui.colorized_frame.fg, which require 10 hex RGB codes (6 hex digits each), e.g.
wireshark -o gui.colorized_frame.bg:${RGB0},${RGB1},${RGB2},${RGB3},${RGB4},${RGB5},${RGB6},${RGB7},${RGB8},${RGB9}
For example, this command yields the same results as the table above (and with all foregrounds set to black):
wireshark -o gui.colorized_frame.bg:ffc0c0,ffc0ff,e0c0e0,c0c0ff,c0e0e0,c0ffff,c0ffc0,ffffc0,e0e0c0,e0e0e0 -o gui.colorized_frame.fg:000000,000000,000000,000000,000000,000000,000000,000000
