popupMenu with dynamic menuItems

[goleafsgo]

I think all you need to change is this:
menuItem -parent test -label $tkLightTrans[$i];
to this:
menuItem -parent test -label $tkLightTrans[0];
That should fix your problem with the menu names.

Not sure what you meant by "...how to pass the list of lights back to my window procedure."?

Hi goleafsgo,


thanks for your reply. I guess the reason why I initially had ...

menuItem -parent test -label $tkLightTrans[$i];

...was to increment $i through the loop and therefore add multiple lights if there were any. If I were to keep it at $tkLightTrans[0], then it would only add the first light in the array. I'm trying to add all of the lights in the scene to the popupMenu.

And what I meant by ..."...how to pass the list of lights back to my window procedure."...is that I have myWin procedure and also bf_lightLister procedure. I wasn't sure of the best working method of getting a list of lights from my bf_lightLister procedure and passing them back as menuItems to the popupMenu in myWin procedure.

Sorry if it's still as clear as mud. :)

i think you are confusing $tkLightTrans and $tkLightShapes...

I wasn't sure of the best working method of getting a list of lights from my bf_lightLister procedure and passing them back as menuItems to the popupMenu in myWin procedure.

your myWin proc builds your UI, within which you build and instruct a popupMenu named 'test' to call bf_lightLister each time it is posted... it is this hard-baked name that allows bf_lightLister to know about the popupMenu and repopulate it with the light list each post (myWin need never be called again after construction...).

Hi Wrend,

thanks for the comments.


I think I have it working. Here is the code for any other beginners looking to learn. Any comments are welcome.

global proc myWin(){

if ((`window -ex exampleWindow`)==1)
deleteUI exampleWindow;

window -title "bf" exampleWindow ;

columnLayout;
button;
string $tkLightPop = `popupMenu -button 1 -pmc bf_lightLister test`;
print $tkLightPop;
showWindow exampleWindow;
}

myWin;

global proc bf_lightLister(){

popupMenu -e -dai test;
string $tkLightShapes[] = `ls -type "light"`;
int $numLights = `size($tkLightShapes)`;
int $i;
string $tkLightTrans[];

for ($i=0;$i<$numLights;$i++){

string $tkLightTrans[] = `listRelatives -p $tkLightShapes[$i]`;
menuItem -parent test -label $tkLightTrans -c ("select "+$tkLightTrans[0]) ;
print $tkLightTrans;

}
}
