Callback typecast removal

Hi,

It's possible to set the callbacks of the GUI elements already in fluid, however when the resulting .cxx file is converted to .lua, the C++ typecast (Fl_Callback*) is also copied to the lua file. See this:

Code:

Fl_Button* o = new Fl_Button(145, 5, 70, 25, "Quit");

o->callback((Fl_Callback*)quitter);

becomes

Code:

do local object = fltk:Fl_Button(145, 5, 70, 25, "Quit");

object:callback((Fl_Callback*)quitter);

I've looked at the converter script and it claims to remove the typecasts, for some reason it doesn't work though. Line 100 in convertFluidToMurgaLua.lua:

Code:

-- Remove casts as they are not required in LUA

currentLine = string.gsub(currentLine, "%(Fl_%w*%)", "")

Keep up the good work! Smile

Tobi

OK, this is the solution:

In the convertFluidToMurgaLua.lua file in line 101 the pattern in the gsub method has an error.
Here's the corrected version:

Code:

currentLine = string.gsub(currentLine, "%(Fl_%w*%*%)", "")

Thanks, I'll test it and put it in the next build ...

I have been traveling for a few days, so I have to catch up on a few things.
