Obtaining values from a table

[pecaN]

Hi, I¨ve quite a silly problem. I want to find out bitmap font's sizes but GetAvailableFonts() returns something like "Table: 0x25F136" or so... and the same goes for the TextExtent() command...please how can i get values from this? I have never come across this so far...thanx pecaN

I pecaN,
generally you can obtain values from a table depending on the table index, for example if you have a table indexed by numeric values:

Code: Select all

Local mytable = { "alpha", "beta", "gamma" }

(*Note)
You can obtain the first item with:

Code: Select all

Print(mytable[0])

the secondo item with

Code: Select all

Print(mytable[1])

and so on...

You can also have tables indexed by strings, for example:

Code: Select all

Local mytable = { item1 = "alpha", itembeta = "beta", gamma = "gamma" }

This time you can obtain values with:

Code: Select all

Print(mytable["item1"])

or even better

Code: Select all

Print(mytable.item1)
Print(mytable.itembeta)
Print(mytable.gamma)

For your specific question you have to look at the documentation of GetAvailableFonts() and see what fields it returns, so you can do something like:

Code: Select all

Local af = GetAvailableFonts()
Print(af.returned_field)

I don't have near me the Hollywood doc so I have used returned_field as a placeholder for the real field returned by this function

(*Note)
note that you can write the table assignment with:

Code: Select all

Local mytable = { [0] = "alpha", [1] = "beta", [2] = "gamma" }

too
