Hello,
me, I am a very beginner. I build a GUI with Glade containing an input- and an output table as well as two buttons. My target is to take the user-input from the input table, process it and put the result to the output table. My first problem is to display the content from the input table for control. With " onClicked inButton (putStr "Hello, World!") " haskell works fine without errors. With " onClicked inButton (??? inTable) " I do not find the right command to display within Prelude.
Thanks for help, Guenter
inButton <- builderGetObject builder castToButton "button1"; outButton <- builderGetObject builder castToButton "button2"; inTable <- builderGetObject builder castToTable "table1";
--onClicked inButton (putStr "Hello, World!"); --0nly for testing onClicked inButton (??? inTable);
Hello. If you can can up with the type of the function, you can try to find it with http://www.haskell.org/hoogle/ .
I actually have a comment regarding your code style. You should know that you can replace
do {x <- foo; y <- bar; z <- baz;}
With do x <- foo y <- bar z <- baz
The second form is far nicer to look at. The first form is pretty much only useful when you want multiple expressions on a single line.
Apologies, my settings got messed up and the message went off encrypted.
