Creating

<ib> = new gmib(style_struct=undefined)
Basic:
ib1 = new gmib();
Using a struct to define style:
ib1 = new gmib({ w: 450, h: 90, text: "Hi there", c_text_unfocused: { c: white, a: 1 } });
Focus right away:
ib1 = new gmib().focus();

Drawing

<ib>.draw(x, y, gui_ev=true)
Draw GUI event:
ib1.draw(50, 60);
Draw event
ib1.draw(50, 60, false);

Focus

There can be just one focused inputbox
An inputbox focuses when you click inside
It's also possible to force focus ib using <ib>.focus()

Style variables

w - (real) text field width, default: 300
h - (real) text field height, default: 110
lh - (real) line height, default: 24
padding - (struct) text offset from borders, default: { top: 4, bottom: 4, left: 4, right: 4 }
char_limit - (real) maximum amount characters, default: infinity
font - (font) font, default: -1 (no font set)
text - (string) set text, default: "" (no text)
letter_case - (GMTF enum) transform every character to upper or lower case, default: GMTF.DEFAULT
min_chw - (real) minimal width of each character, default: 0 (WARNING: values other than 0 will make the text render character by character instead of line by line)
stoppers - (string) characters which stop the cursor while moving using ctrl, default: " .,()[]{}<>?|:\\+-*/=" + chr(29)

Colors

c_bkg_unfocused - (struct) unfocused background color and alpha, default: { c: c_gray, a: 1 }
c_bkg_focused - (struct) focused background color and alpha, default: { c: c_ltgray, a: 1 }
c_text_unfocused - (struct) unfocused text color and alpha, default: { c: c_black, a: 1 }
c_text_focused - (struct) focused text color and alpha, default: { c: c_black, a: 1 }
c_selection - (struct) mouse selection color and alpha, default: { c: c_blue, a: 0.275 }

Style can be changed later by calling tf1.set_style(<style_struct>)
WARNING: Do not run style changes (except colors) every step since it has to update every single character and line which will cause lag

Text field switching

ib1.set_next(ib2);
ib2.set_next(ib3);
ib3.set_next(ib1);
ib1.set_previous(ib3);
ib3.set_previous(ib2);
ib2.set_previous(ib1);

After these are set you can switch inputboxes using Tab (next) and Shift+Tab (previous)

Get/Set text

<ib>.get_text(keep_enters=false);
keep_enters:
false (default): replace enter characters chr(29) with regular \n characters
true: keep original enter characters chr(29), useful when copying between inputboxes

<ib>.set_text(text);
Replace whatever is inside with a new text
