Hi Fabio,

is it possible to give a parameter to a function, that I call on the OnPushed (respectively OnChanged ...) event? Sth like
Code:
...
{ OnPushed = myFunc("My Text") }

or
Code:
...
{ OnPushed = myFunc(myVar$) }

If yes - how do I do that? :-)

Thanks a lot! ... and dig out your soul! :-)

Micha

Hi Micha,
if I've understood what you mean, you want to assign to an event a function with a variable parameter... well, actually it's not supported but is easy to implement this feature.
Actually the function you assign is called with only one parameter, a table containing the member <id> and <event>, respectively the numeric id of the activated gadget and the event that has generated the function call, I can add another parameter that can be a custom table with your personal parameters.
In the meantime you can handle your functions using global variables and/or switching the right value checking the <id> of the activated gadget.

Supposing you have planned something like:
Gadget "ButtonA"
Code:
{ OnPushed = fPrintSomething("Something") }

Gadget "ButtonB"
Code:
{ OnPushed = fPrintSomething("Something else...") }


You can use this code:
Gadget "ButtonA"
Code:
{ OnPushed = fPrintSomething() }

Gadget "ButtonB"
Code:
{ OnPushed = fPrintSomething() }

Code:
function fPrintSomething(msg)
   Local ButtonA_id = scui.GetIFOID("ButtonA")
   Local ButtonB_id = scui.GetIFOID("ButtonB")
   Local MyString = ""
   Switch msg.id
      Case ButtonA_id
         MyString = "Something"
      Case ButtonB_id
         MyString = "Something else..."
   EndSwitch

   Print(MyString)
EndFunction


This is just an example, hope it can helps :D

Good coding :wink:
Fabio

Thank you Micha, I'm happy to help in any way and even more happy to see that you like my work :)

btw I'm not sure if I can include this feature in the 0.6, I'd like to close the next version with Menus, Image and Virtual Area classes, some example to show their use and updated documentation.

cya around mate :)

Yep, not necessary to include it to 0.6. Would be better to publish it soon. :-) Any concrete dates available? :-) Or just "when it's done"? ;-)

Cheers

Well, all depends on my RL work I've estimated 2/3 weeks, if I cannot be able to update the documentation (this is the last work I will do) I will publish the new version without it, but I will include for sure some examples showing the new function in action.

Ok, I just want to correct the following code:
Allanon wrote:
Code:
function fPrintSomething(msg)
   Local ButtonA_id = scui.GetIFOID("ButtonA")
   Local ButtonB_id = scui.GetIFOID("ButtonB")
   Local MyString = ""
   Switch msg.id
      Case ButtonA_id
         MyString = "Something"
      Case ButtonB_id
         MyString = "Something else..."
   EndSwitch

   Print(MyString)
EndFunction


This does not work, because the case branch always as to be a constant value, not a varible in Hollywood ... :-(

So, in order to get it work you have to write the following:
Code:
If msg.id = Case ButtonA_id
         MyString = "Something"
      ElseIf msg.id = ButtonB_id
         MyString = "Something else..."
EndIf

Hope, that helps other people around here ...

Greetings,
Micha
