Here is an commented example of a procedure I use in one of my scripts to
build a listbox from the contents of a particular directory. I hope it
helps.
proc msb_buildListbox () //Builds my effects listbox from contents of a
directory
{
//I need to use these globals
global string $SOE_EFFECTPATH;
//Put my files into an array
string $effectList[] = sort(`getFileList -fld $SOE_EFFECTPATH -fs
"*.eft"`);
//Begin building textScrollList command for eval later
string $appendList = "textScrollList";
//Loop on contents of my directory and append each onto my command
for ($effect in $effectList)
{
$appendList = $appendList + " -a \"" + $effect + "\"";
}
//Finish off command with other flags
$appendList = $appendList + " -sc \"msb_getEffectInfo\"
effectListbox";
//DEBUG - this is here so I can check that the command gets created
properly
print ($appendList +"\n");
//Eval the command to create the actual control
eval ($appendList);
} //end msb_buildListBox

Hi,
I�m a student of Alias Maya and I just started with MEL Scripting.
I have a question about how can i do some things... but one is making me
specially crazy!
I have a "textScrollList" and i don�t wanna to put flags manually. Before to
enter to the definition of this control, i define a string and I assign the
text of the flag like this:
---
string $texto = "-append \"1a\" -append \"1b\" -append \"1c\"";
---
So later, i dunno how to put inside of the control. I tried this but script
editor says me that the flag is invalid (I have a layout and a window but I
will don�t show the code here):
---
textScrollList -numberOfRows 8 -allowMultiSelection true
-p estBaseVentana
($texto);
---
My question is... how can i put this string and not recibe an error ? I
tried to put the same text manually and it works perfectly. I need this
because i will make a "while" to determine all the elements to put on this
list.
The other question is how can i do a loop like a "While" inside a control ?
it�s making me crazy! The control thinks that i�m putting flags and always
give me error
any help will be appreciated
Sorry for my english, it�s a little difficult for me. Hope u understand me!
:P
