I started out using ArrayCtrl because I didn't see GridCtrl right off. It works good, but since it stores Value objects I wondered if it might not be faster if it was just string objects.

I found GridCtrl and got it to work. I put both next to each other and just flipped the names between them in the layout and compared the behavior on a large set.

My notes:
- ArrayCtrl has the Accel function, which filters keystrokes and scans ahead to the first matching grid item. I'll steal the code, clone GridCtrl and add it Smile because its a nifty feature for me. I'll probably try to make it multi-character, too.
- ArrayCtrl works with dynamically created windows, but GridCtrl blows chunks in the destructor somewhere. I shouldn't have been using dynamic construction anyway, but it's nice to know for when I do.

- GridCtrl has:
Viewable row count
Interactive row resize (I think)
3-state sort marker, ArrayCtrl is 2 state
Loads faster
Lets user size header height, which is nice
Doesn't flicker when multithreaded (GREAT!)
"live" mouse hover highlight works great
Default context menu is prettier, better icons
Has clipboard built in
Has alternating row coloring with single setting
Sorts much faster than ArrayCtrl for smaller sets
No memory leaks on either with MT (except with dynamic window)

I'm going with GridCtrl because of the no flicker. I use threads to populate the grid and let the user interact with it on the main thread, so flicker is considerable.

Anyone else try both? I'm curious what other differences there are when stacked up against each other.

If you want to avoid flickering for arrayctrl just do:
ArrayCtrl arr;
arr.BackPaint();

You can use the same in GridCtrl but in most cases it's not necessary.

I agree with many of your experiences.

I would add two pros for ArrayCtrl that are that it handles Drag & Drop and it is very easy to set a full control inside a simple cell.

What do you mean by "full control"?

Performance difference would be negligible, but you would loose a lot of functionality. What about images in cells? Smile

As I see it, ArrayCtrl is headed more to be used as building block (in fact, it is used even for such things like DropList), whereas GridCtrl is geared towards a lot of prebuild functions.

As for flickering, it is very easy to make U++ app completely flicker-free. Use:

Ctrl::GlobalBackPaint();

or

Ctrl::GlobalBackPaintHint();

(second one makes U++ flicker free only if windows is >=XP and machine has more than 512MB - heurestic indication that the machine is OK).

The reason why this is not default is that on many machines in the past (2 years back), there was visible speed difference between modes.

Well, I guess, today we could make at least GlobalBackPaintHint default... Smile

Hello Alendar,

I'm using GridCtrl for dynamically created windows. I don't noticed such problem. Any details? Just need to know, I want to avoid the problems with GridCtrl in future.

Best regards,
Anton

If it does, it is not a designed feature Smile It is a bug - you shold try to create a "testcase" and post it to the GridCtrl forum.

No bugs are to be tolerated...

I mean you can design a full StaticCtrl with other controls inside and put it easily into an ArrayCtrl cell.

Smile, yeh, I 50% guessed so. But I had just started worrying where could it be a possibility to lose "full control" in GridCtrl... Laughing
Anyway, if you or anyone else wants this feature (Set external Ctrl) (and some other features, eg. column selection...) you can freely borrow some or all of the tweaks from the files below.

In fact, I'm so in love with GridCtrl (fantastic job uno!) that I started to "gridizice" my version of theide.

Wow! That should be me first with "gridiziced" ide Smile. I see you know GridCtrl quite deep. Sorry for getting the knowledge without documentation.. I must finally finish it (to avoid this repeated question about difference to arrayctrl and to reveal all grid features)

Thank you for your appreciation!

Documentation is not a big problem if one can have the sources in nicely programmed u++ Smile.

Also, please have in mind that if, one wants to use the files from the zip above, he/she must merge/copy the relevant changes. This is because I use GridCtrl intgrated into CtrlLib due to (my?) inability to use it for CtrlLib (AKeys esp).

Thanks! I'll try both. I hate to not support things before XP. I have a soft heart for NT.

I'll try to do a test case, but since I use Windows 7 with VC 10.0 (2010) it might not be a very relevant test to most people's envs. I tried various MinGW versions and had other problems with my code. I'll try VC 9.0 (2008) which is probably fairly standard.

Well, I can't duplicate it now. Boy is my face red!
