#1233 — how do I find a window handle?

I am trying to write an application using AppBasic and am having a
bit of trouble working out how much I have to code myself and how much 
I can leave to the builtin facilities.

For example my app has three windows which are opened by clicking on 
iconbar menu entries.

I would like to change a display field when the mouse pointer enters
one of the windows. In order to do this I need to know
the window id of the window concerned.

At the moment the system creates the windows
with ToolBoxAutocreated, so don't know the handles.

Is there a way to determine a window handle
for a window that has been auto-created or do I have to
create the windows myself?

I do not know if AppBasic implements it in itself, but I would use SWI 
Window_GetPointerInfo, which you could use just as it is.

Yes - PROCWindow_GetPointerInfo(object,component,x,y,buttons) gives 
the window handle and winame$=FNUtils_Object(object) returns the name 
of the window as it appears in the Res file.

Thanks for pointing me in the right direction:-)

ToolBoxAutocreated Objects should produce an Toolbox Event wich is sent 
back to the Application to inform it about the automatically created 
object (Toolbox_ObjectAutoCreated). This can be checked to get the 
correct handles.

After that the now known handles can be used to check them against 
WimpPoll Event No. 5 wich occurs when the pointer enters a new window.
(Keep in mind, that there is a Pollmask, wich is able to switch this 
function on/off. In AppBasic FNUtils_GetPollMask should be checked if 
PollEvents dosn't work.)

Here is an interesting link for You:
