understanding the Func WM_NOTIFY

7 posts in this topic

hello again

this time, I’m trying to use treeviews with the click detection, 

after a couple of days of  search on the help file, the forums and example files, i found the best way is use the WM_NOTIFY function, but i cant make it work how i want

but for what i see this function it's pre-processed before the click, and it mark the last item instead the actual one

 

 

I had to seek for info because I started to  make a similar thing:

        EndSwitch
    WEnd
EndFunc

but the problem was that when i hit a button they not only do the button “case”, it do both, checking/unchecking the selected item on the tree

 

well i dont have any ideas left so i come here to beg for some help XD

sirWimelef,

This seems to be what you want.  Changed the notification to SELCHANGEDW.  Have not looked at the checkbox problem as this may lead you to a solution for that.

from where you get that variable? it isn’t on the help files,  there is somewhere where i can get all the valid triggers?

 

DatMCEyeBall i reader it, and non of theme work for what i want, also with that function i cant hook the treeview to the tab and it hover over theme

 

another question thas bugging me with this, there a way to use this function without using global variables?

sirWimelef,

 

from where you get that variable? it isn’t on the help files, there is somewhere where i can get all the valid triggers?

 

These variables are call "notifications" and are documented in MSDN for each control. 

another

question thas bugging me with this, there a way to use this function without using global variables?

 

That depends on what you want to do.  The notification function operates like all other funcitons with regard to variable scope.  If you want to use a value from the notification funciton then you need to set a "global" variable to that value or pass it as a parameter.

Lastly, the Help file covers definition and syntax, often with an accompanying example.  It is not meant to cover all possible uses of the definition.  I agree, however, that pointing you back at the Help file was useless as you had obviously been there and your issue was beyond it's scope.

Good Luck,

kylomas

thx for all

 

now i have another "help file" to check before seek here XD 

if someone read this and don’t want too seek on msdn here is the link

http://msdn.microsoft.com/en-us/library/windows/desktop/bb773169(v=vs.85).aspx

 

 

for the second part, i hate global variables, they are "patches" on the code to make things work 

when i call the function with 

GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")

in the help file say explicit that u can only call it with a max 4 predefined parameters so i cand send the 3 treeviews variables to it

 

 

but well this work and I’m hapy with it XD

sirWimelef,

Don't confuse parameters required with "global" vars.  The "message" routines (notiification, command, etc) have a strict calling convention.  This does not mean that you cannot set a global var while in the function for use outside of the funciton.  In fact, it is advised to exit these functions as soon as possible so as not to block script execution.  Therefore you will often use a "switch" to indicate some sort of processing in the main part of the code (message loop, generally). 

they are "patches" on the code to make things work

 

I'm not sure that I agree with this, this is simply a matter of variable scoping (my opinion only).
