#1815 — Wimp report error oddity

Hi,

Getting something I don't understand and would appreciate enlightenment.

My Wimp application waits for an icon click within the program and then
tries to load a file. If the file doesn't load or contains no data I call
wimp_report_error with the flags set to 1.
After return from the swi I simply go back to the main loop and wimp_poll.

All seems well, the error box pops up with the correct text and if you
press return or escape the window closes perfectly. However, if you click
the OK button in the error window, the window closes and opens again. A
second click of the OK button closes the window properly.

It looks to me as though the previous mouse click is being picked up a
second time. I made sure my mouse click code checks the window handle and
unless it is from MY main window it cannot call the file load a second
time.  

Got me going this one. Anyone care to point out my no doubt obvious
mistake?


Cheers,

Bob.

No idea, but if you run !reporter you'll be able to see the flow of control
through the program, and issue diagnostic messages to yourself.

Really, really stumped by this, I don't understand what is happening or
why. I've spent hours and hours on it.

Having put test points in my code I can confirm that the original mouse
click does get resent to my application after a Wimp_ReportEerror *if* I
close the error window with a mouse click, use the escape key and no
problems.

Is this expected behaviour? 

Do I have to flush some buffer or something?

Can anyone give me a clue please?

TIA

Bob.

Very odd. I presume the window handle in that message is the one of 
the original window? Check the button type of the icon in question. It 
could be of a type that notifies both on click and on release.

Spot on! You're a genius.

Somehow the icon had got set to Click/Drag and all the other icons were
just Click. It would never have occurred to me to check this, convinced as
I was that I'd done something stupid in my code. It's funny (now) but that
button must have been set wrong for months if not years and it never gave
a problem until I started to add error messages.

Thank you Martin, much appreciated.


Cheers,

Bob.
