CEGUI (Crazy Eddie's GUI) Forums

Hi Guys

okidoki thanks to ScriptKid who pointed me in the right direction for my last problem

i know have files from a folder being displayed in the combobox list

my problem is whats the correct way of seeing an EventSelectionChanged

as this will be needed to set up other things in the window according to which file is loaded

ie how to ->subscribeEvent

I thought it would be simmiler to the way listbox works

I tried a few ways but cant seem to get this to work one way was



where setFile is a function for changing and refreshing the window

TIA

Hi,

you're welcome

For a combo box you need:


which is only called when the user actually closed the list by clicking an item.

HTH.

hi ya


Thanks again ScriptKid

could you just confirm this will only work if pointing to a bool function
what i mean is the function SetFile is a int i get this error when compiling

int (__cdecl *)(const _TCHAR *,CEGUI::Combobox *)' : too few arguments for call

should i change this in function to a bool

sry if that sounds a dumb question

TIA

Hi,

i am not sure about the int/bool thing, but your error doesn't talk about the return type. It looks like the format of the function is wrong, it should be something like:



Good luck!

hi ScriptKid


i've tried as above and various other ways but i keep getting

term does not evaluate to a function taking 1 arguments

i also tried


which gives me this

global functions do not have 'this' pointers
'CEGUI::SubscriberSlot::SubscriberSlot' : no overloaded function takes 2 arguments

which from how i understand it is the expected errors from the searches i have done but i'am unable to fix this issue could you point me in the right direction please

TIA

you need to show how you are declaring and defining MyUI::SetFile. It sounds like you did not define the function correctly.

hiya

if i understand you correctly

in my h file i have



then in the cpp i have

Hello,

The error

global functions do not have 'this' pointers

implies that you are calling



from within a global function - in which case it is quite accurate... there is no 'this' pointer from within a global function.

Therefore, you need to call subscribeEvent(...) as above from within a function inside the MyUI class - such as the constructor.

Yeah, I went off in the wrong direction there. Kevin is right - if you are not calling subscribeEvent() from a method within MyUI you cannot use the 'this' pointer. You can move the subscribeEvent() call into a MyUI method like the constructior, as Kevin mentioned. You can also just pass the actual pointer to the object instead of trying to pass 'this' in the global function you are using. Ex:

Thanks guys

thats got it to compile

just get an out of range error now on the string file ?

TIA
