[TC10.52rc1 x64] Double click in separate tree, wrong folder selected

[white]

• Enable one or two Separate Trees (Ctrl+Shift+F8)
• Double-click a folder located in the lower part of the separate tree panel

The tree scrolls up (normal) and the wrong folder is selected (64-bit only).

Tested using Windows 11 (22H2).
Problem occurs since first 64-bit version of Total Commander.

[Horst.Epp]

Can not confirm
Tested with one seperate tree under Windows 11 22H2
Why do you make a double click ?
A single click is enough.

[white]

Why do you make a double click ?

With default options, double click opens the folder and expands/collapses that folder in the tree.

Not confirmed - tested under Windows 7 and 10

Did the tree scroll? This is a requirement.
Did you do exactly the same tests using 32-bit and 64-bit and compared the difference?

Did the tree scroll? This is a requirement.

Now I see it - I can confirm it for both 32bit and 64bit TC. It is not new, it also occurs in TC 10.51

It is timing dependent - on my slow Windows 10 PC I don't always see it, if it takes longer for TC to start the unfolding (big dirs) than the time between the two clicks.

[ghisler(Author)]

Not confirmed. The tree did scroll.

Try with some large folder like C:\windows\system32 and make sure that system32 is the very last visible folder in the tree panel before you double-click on it

[white]

I have created 2 videos. Steps I did in the videos:

1. Double click folder A to collapse it
2. Double click folder A to expand it again
3. Scroll the tree a bit
4. Repeat step 1 and 2

When using TC 32-bit, folder A is always selected: animated gif
When using TC 64-bit, folder 3 is selected at the end: animated gif

It looks like races (in navigating conflict). In some cases line cursor is moved to mouse cursor and stabilized before scrolling, in other cases line cursor is moved to mouse cursor and stabilized after scrolling (these are races). Note that mouse cursor isn't moved and the line selected is under the mouse cursor (this is navigating conflict).

You might probably see similar actions when navigating on some list with keyboard, but finally the line under mouse cursor was selected. In TC you can press Ctrl+D and navigate with keyboard, then move (accidentally hit) mouse over the directory hotlist and line cursor will follow the mouse movement. That's why I try too keep mouse outside of TC window when unused.

It looks like races (in navigating conflict).

So far I could not reproduce it, it probably only happens when the PC shows the results too slowly.

So far I could not reproduce it..

Perhaps if you use my test folders and do exactly as I did.

Save the file contents below to a file named "Test folders.b64". Execute this file in TC to create the zip file. Extract the zip file to create a bunch of empty folders.

Start TC 64-bit, expand all the folders in the separate tree, scroll the separate tree until the folder "7" above folder "A" is at the top, resize the TC window until the separate tree shows a bit more than the "B" folder.

In the separate tree: double click "A", double click "A" (results OK), scroll down a bit so folder "4" is at the top, double click "A", double click "A" (folder 3 is selected).

Thanks, now I can reproduce it. It looks like Lazarus sends too many events for a double click:
single click down, single click up, double click, another single click down, single click up.
Delphi (TC 32-bit) does not send this second single click down event. Ignoring it seems to fix the problem.

09.10.22 Fixed: Separate tree: double clicking on a folder which causes it to expand and the list to scroll could place cursor on wrong folder (64)

Confirmed fixed in TC 10.52rc2 as far as I can see

Sonfrimed fixed in TC 10.52rc2 as far as I can see

If you mean confirmed then confirmed
