Length of string

[Lode 19]

Hi,

 

I "stole" a piece of code from @jgab and i'm trying to make a label where you can put in a timevalue like "12:50"

So far so good.

I need to determine the length of a string but that doesn't seem to work.

When i debug "lengte" i get a nil value.

Your fibaro.debug is  the problem - it needs a  tag as the first argument. 

fibaro.debug(__TAG,lengte)

Now it takes your length argument as the tag and it will not show....

__TAG is usually bound to  "QUICKAPP"..self.id

 

Because you are passing self to add you can also use the QuickApp  method debug that doesn't use a tag.

 

self:debug(lengte)

 

If you do a lot of   coding I would recommend that you use my offline HC3 emulator where you can debug the code properly on your PC/Mac

Another tip.

When you exit the QuickApp:onInit() function , the global lua variable 'quickApp' is  assigned the QuickApp object (aka 'self')

This means that you can do

The only reason to pass  around self is if you have a lot of QuickApp objects (ex. if you have QuickAppChild objects).
