A Quick Question, Please

[The Artful Dodger]

Hello:

Is there a way to substitute a color name, (like "green" or "blue"), or a hex value (like #FF8000 or #DDA0DD) with a variable name? For instance:

Code: Select all

ARB_35_HAC_VAC   = "font: Arimo-Bold.ttf;  size: 35px; color: MySpecialGreen; halign: center; valign: center; weight: bold;"

For that matter, the same would go for the size:

Code: Select all

ARB_35_HAC_VAC   = "font: Arimo-Bold.ttf;  size: MyTextSizepx; color: #008000; halign: center; valign: center; weight: bold;"

This would allow me to change these parameters much more easily.

Thanks in advance.

Yes you can.

Code: Select all

perenmoes = "font:roboto_bold.ttf;"
appelmoes = "size:60;"
mytext1 = txt_add("hello world", perenmoes .. appelmoes .. "color: red; halign:left;", 0, 0, 200, 200)

Hi, Ralph:

WOW - it would probably have been well into the next century before I would have figured that one out! Thanks!!

You can use the standard colour code hash as well ......

Code: Select all

perenmoes = "font:roboto_bold.ttf;"
appelmoes = "size:60;"
maxverstappen = "color:#FE6D26;"
 mytext1 = txt_add("hello world", perenmoes .. appelmoes .. maxverstappen.. "halign:left;", 0, 0, 250, 200)

Hi, Guys:

It isn't the language I don't understand; I know concatenation very well. It's just that it never occurred to me to use it. Plus, FYI, I have a copy of the fourth edition of that book. But, if I didn't think of concatenation in the first place, I never would have found it. As soon as I saw the "..", the light bulb clicked on!

Thanks to both of you.

It is indeed difficult to get this from a book. You would at least have to know the term 'concatenate'.

It makes you go blind......
