Using event handlers - (EasyVENT version 3.2)

DoubleDutch · Post by **DoubleDutch** » Fri Oct 12, 2007 11:38 pm

On NT4 if you EasyVent the #OnDragItemStart message on a tree (it may happen on other gadgets I haven't checked) then the scroll bars (both H & V) for the gadget don't work unless double-clicked.

I've checked and when you click on the scrollbar the #OnDragItemStart message is called.

The #OnDragItemStart message performs as it should in all other respects on NT4.

Any ideas on how to fix this?

Bloody NT 4!!!

Sounds like either a mouse capture issue or one stemming from the fact that, at certain points related to the #OnDragItemStart process, default window's processing is not called.

Try this first :

change the line

Code: Select all

If GetProp_(hwnd,"EVENT_"+Str(#OnDragItemStart))

to

Code: Select all

If GetProp_(hwnd,"EVENT_"+Str(#OnDragItemStart)) And uMsg = #WM_LBUTTONDOWN

Looks like it's to do with themes, not just NT4 - it happens on anything where themes are disabled.

But....

Your fixed worked!!!

Which confirms the mouse capture theory!

The problem then is in my extending the mouse messages to include their non-client counterparts.

Can you double check the fix if you don't mind.

I don't want to release a fix if there's still a chance that things are still amis!

Thanks.

I've checked it on NT4, XP (with & without themes), 98 SE, 95, Me, 2K & Vista!

I didn't just check that the gadget scrollbar worked fine, I also did a check that the drag/drop was also working ok. I only checked trees.

Looks fixed.

You should do what I do: I have a machine with virtual PC and all the different types of windows setup (xp with & without themes). It's pretty easy to check things out then. The latest Virtual PC is free from Microsoft.

Yes, but that would then mean I'd have no excuse for not performing all the checks myself! This way I can get others do do all the leg work (but mum's the word!)

Thanks, I'll upload the fix right now.

Slightly inaccurate: The problem occured on ALL systems when themes were disabled (which is the default on pre-XP because there are no such things as themes on pre-XP).
