-- Helper functions for miniwindows
--
-- Author: Nick Gammon - 8th September 2008
--[[
Exposed functions are:
mw.colourtext - show a string with imbedded colour codes
mw.colour_conversion - table with colour codes in it - add more if you want
mw.strip_colours - remove colour codes from a string
mw.popup - make a popup window
mw.tooltip - make a tooltip window
EXAMPLE OF MAKING A POPUP WINDOW:
require "mw"
-- SET UP FOR POPUP WINDOWS - define colours, add fonts, make window id
-- (DO THIS ONCE ONLY, eg. in OnPluginInstall)
-- our window frame/background colours
border_colour = 0xCCD148
background_colour = 0x222222
-- a unique ID
infowin = GetPluginID () .. ":info"
-- font IDs
font_id = "popup_font"
heading_font_id = "popup_heading_font"
font_size = 8
-- use 8 pt Dina or 10 pt Courier
local fonts = utils.getfontfamilies ()
-- choose a font that exists
if fonts.Dina then
font_name = "Dina"
elseif fonts ["Lucida Sans Unicode"] then
font_name = "Lucida Sans Unicode"
else
font_size = 10
font_name = "Courier"
end -- if
-- load fonts
WindowCreate (infowin, 0, 0, 0, 0, 0, 0, 0) -- make initial window
-- install the fonts
WindowFont (infowin, font_id, font_name, font_size, false, false, false, false,
miniwin.font_charset_ansi,
miniwin.font_family_modern + miniwin.font_pitch_fixed)
WindowFont (infowin, heading_font_id, font_name, font_size + 2, false, false, false, false,
miniwin.font_charset_ansi,
miniwin.font_family_modern + miniwin.font_pitch_fixed)
-- NOW DISPLAY A WINDOW
-- what to say - one line per table entry, with imbedded colour codes
info = { "@Ctesting 1 2 3",
"@GThis is a heading",
"Line @Mwith @Bmultiple @Rcolours",
}
heading = "@MHello, @Yworld"
left, top = 40, 50
align_right = false
align_bottom = false
capitalize = true
-- show it
mw.popup (infowin, -- window name to use
heading_font_id, -- font to use for the heading
font_id, -- font to use for each line
heading, -- heading text
info, -- table of lines to show (with colour codes)
left, top, -- where to put it
border_colour, -- colour for round rectangle line
background_colour, -- colour for background
capitalize, -- if true, force the first letter to upper case
align_right, -- if true, align right side on "Left" parameter
align_bottom) -- if true, align bottom side on "Top" parameter
EXAMPLE OF MAKING A TOOLTIP WINDOW:
-- SET UP FOR TOOLTIP WINDOWS - define colours, add fonts, make window id
-- (DO THIS ONCE ONLY, eg. in OnPluginInstall)
-- Example setup code:
require "mw"
-- get ready for tooltips
win_tooltip = GetPluginID () .. "_tooltip"
font_tooltip = "tf"
bold_font_tooltip = "tfb"
-- make the window
WindowCreate (win_tooltip, 0, 0, 0, 0, 0, 0, 0)
-- load some fonts into it
WindowFont (win_tooltip, font_tooltip, "Tahoma", 8)
WindowFont (win_tooltip, bold_font_tooltip, "Tahoma", 8, true)
-- NOW DISPLAY A tooltip (Put bold lines inside asterisks)
mw.tooltip (win_tooltip, -- window name to use
font_tooltip, -- font to use for each line
bold_font_tooltip, -- bold font
"*Info*\nHello, world!\nHave fun.", -- tooltip text
45, 75, -- where to put it (x, y)
0, -- colour for text (black)
0, -- colour for border (black)
ColourNameToRGB ("#FFFFE1")) -- colour for background
