Since MaxiJavi introduced murgaLua to these forums, and since John Murga himself was kind enough to build a version which works great in DSL with no additional dependencies, I thought it'd be a crime not to dive into it. So....as I struggle to learn the differences between this application and Lua-FLTK, I'll be posting what I learn here.
The first bit is a demonstration of standard buttons. Comparing murgaLua to FLTK, there seem to be only 3 button types that are not supported: shadow, rounded, and diamond. Those three are, in my opinion, fairly useless anyway =o)
| Code Sample | ww=360 --window width
wh=420 --window height
presses = 0 -- used for the repeat button
function button_press(self)
if self == butts[10] or self == butts[11] or self == butts[12] then
if self:value() == 1 then status="activated" else status="deactivated" end
out:value("\""..self:label().."\" was "..status)
presses = 0
elseif self == butts[9] then
presses = presses+1
out:value("\""..self:label().."\" was pressed "..presses.." times")
else
out:value("\""..self:label().."\" was pressed")
presses = 0
end
end
w=fltk:Fl_Window(ww,wh,"murgaLua Button Demo")
butts={}

---- Here are two methods of laying out an array of similar widgets
-- Method 1
--butts[1]=fltk:Fl_Button(10,10,ww-20,25,"Fl_Button default")
--butts[2]=fltk:Fl_Button(10,40,ww-20,25,"Fl_Button down")
--butts[3]=fltk:Fl_Button(10,70,ww-20,25,"Fl_Button thin")
--butts[4]=fltk:Fl_Button(10,100,ww-20,25,"Fl_Button thin down")
--butts[5]=fltk:Fl_Button(10,130,ww-20,25,"Fl_Button engraved")
--butts[6]=fltk:Fl_Button(10,160,ww-20,25,"Fl_Button embossed")
--butts[7]=fltk:Fl_Button(10,190,ww-20,25,"Fl_Button border")
-- Method 2
labels={"default","down","thin","thin down","engraved","embossed","border"}
for i = 1,7 do butts[i]=fltk:Fl_Button(10,30*i-20,ww-20,25,"Fl_Button "..labels[i]) end
----------
butts[2]:box(fltk.FL_DOWN_BOX)
butts[3]:box(fltk.FL_THIN_UP_BOX)
butts[4]:box(fltk.FL_THIN_DOWN_BOX)
butts[5]:box(fltk.FL_ENGRAVED_BOX)
butts[6]:box(fltk.FL_EMBOSSED_BOX)
butts[7]:box(fltk.FL_BORDER_BOX)
butts[8]=fltk:Fl_Return_Button(10,220,ww-20,25,"Fl_Return_Button")
butts[9]=fltk:Fl_Repeat_Button(10,250,ww-20,25,"Fl_Repeat_Button")
butts[10]=fltk:Fl_Light_Button(10,280,ww-20,25,"Fl_Light_Button")
butts[11]=fltk:Fl_Round_Button(10,310,ww-20,25,"Fl_Round_Button")
butts[12]=fltk:Fl_Check_Button(10,340,ww-20,25,"Fl_Check_Button")
for i = 1,12 do
butts[i]:callback(button_press)
end
out=fltk:Fl_Output(10,370,ww-20,25)
w:show()
Fl:run()

The second one is just a clock widget...nothing special or interactive added to it, but i thought it was kind of an interesting widget to include in such a small toolbox.
| Code Sample | ww=180 --window width
wh=200 --window height
w=fltk:Fl_Window(ww,wh,"murgaLua Clock Demo")
clock=fltk:Fl_Clock(5,5,ww-10,ww-10,"a clock")
clock:box(fltk.FL_DOWN_BOX)
w:show()
Fl:run() |
