[9.0ß6-x64] Tab key does not work

[jvh]

Sorry, I open it again but now, after deep investigation, I have found a trigger. It's related to this topic but maybe it has an impact on other similar issues...

Steps to reproduce:
1. Add to wincmd.ini / [Configuration] parameter MinLineHeight=0
2. Make sure that you use some Aero theme (e.g. Windows 7)
3. Run TC 9.0b6 x64
4. Switch windows theme to Classic
5. Try Tab key in file panels
- TC 9.0b6 x64 - Tab key does not respond

- MinLineHeight value can be 0 or greater. If it's less than 0 Tab key works normally.
- Switching back to Aero theme doesn't help, TC's restart is necessary.
- Repetable on Win 7 64-bit and TC 9.0b6 x64.
- TC 9.0b6 x86 works as expected.

Can confirm someone else?

[Dalai]

Confirmed. It's even worse: If any tabs were open, you can switch between them but there's no content in the file lists after doing so! Ctrl+R doesn't help either. Furthermore, only the left panel is active, I haven't found a way to switch to the right panel.

So it's an issue different from the non-working TAB key in some of the dialogs, and it seems to be triggered by disabling themes and the non-functional TAB key is just one of the errors.

[ADD]
Changing MinLineHeight in Configuration dialog is able to "revive" TC, so directory contents are shown and TAB key works again.
[/ADD]

[ADD2]
The trigger is disabling OR enabling themes. So it can be triggered by using Classic theme, launching TC and then enabling themes while TC is running.

Not fully fixed in TC 9.0b7 x64.

Repetable if you don't press tab key before changing theme.
(Same steps as in post #1) but:
3. Run TC 9.0b7 x64 + don't press Tab key neither Alt+Tab. (Use Winkey+D for invoking Screen properties and change theme from Desktop or open Individual setting before step 3).

- There is a little difference against Beta 6 - cursor (dotted rectangle on the file) is visible now.
- If you press Tab key before changing theme, TC works without problem.
- TC can be "revived" with using Alt+Tab from TC window to Individual setting window and change theme, but in this case is current file/folder selected for some reasons.

I can't reproduce it anymore in beta7. I don't press TAB or Alt+Tab before switching themes, I have the settings window always open and switch to/from it with the mouse via the Windows taskbar.

Thanks for testing. I tried it again and if I use only Windows taskbar with mouse, this bug happened just occasionally. Strange, but if I use Winkey+D it happens always.

Please try in step 3:
- Run TC 9.0b7 x64
- press Winkey+D to go to Desktop
- right mouse click + invoking Screen properties/Individual setting
- change theme from some Aero to Classic
- then try Tab key in TC (you can use mouse on Windows taskbar or Alt+Tab key now)

I don't have a Windows key on my keyboard so I can't try that. Yes, I use really old keyboards on purpose; I don't need any Windows key or context menu stuff, I just need a keyboard that's good to type and use.

Windows+D indeed causes a difference here: When I click on the TC icon after changing the theme, there are no filelists. But when I press Tab, they both appear. I cannot reproduce the problem that Tab itself doesn't work. But maybe my fix about the disappearing windows will help with your problem too...

[ghisler(Author)]

Please let me know what you get with beta 8 now.

Btw, how do you restore TC after changing the theme? You minimized TC with Winkey+D.

[jvh]

No change in TC 9.0b8 x64 and TC 9.0b9 x64.

When I click on the TC icon after changing the theme, there are no filelists.

Strange, I see filelists in both panels. The focus is in left panel and I can use all keys except Tab and left panel reacts as expected. I cannot focus right panel with Tab key or single mouse click. Right panel can get focus with mouse double click, but cursor isn't visible in filelist. If I use now Down/Up key the cursor appears and after several keystrokes (Up/Down key, Enter etc.) I got this:

I tried restore TC with Alt+Tab key or with mouse click on Taskbar. The bug persists in both cases


Please let me know if you want some additional information...


P.S.: Sorry for late answer, holiday time...

Sorry, I cannot reproduce your problems any longer.

Since users normally don't change themes all the time, I think it can be demanded that users just restart TC when they get this problem. I have already spent hours on this sh*t and don't want to lose any more time, sorry.

OK, no problem for me, I usually don't change themes, just found this bug while testing another one in previous TC's version.

Please note that trigger for this bug is still MinLineHeight=0.

[ghisler(Author)]

Yes, I'm aware of that. However, I still can't reproduce it.

One thing which isn't clear: How do you restore TC after changing the theme? As I understand it, you minimize all programs with Windows+D. Then you change the theme. Now you somehow return to the minimized TC and press Tab.

I tried the following methods to return to TC:
1. Click on its icon in the task bar with the mouse
2. Press Alt+Tab until TC is restored
3. TC in system tray, click on its icon to restore
4. TC in system tray, press Alt+Tab, then Enter to restore

I also tried
- with tabs
- without tabs
- with separate tree panel
- without separate tree panel

Tab worked in ALL these cases. I tried this on Windows 7 x64 and Windows 10 x64, with fresh settings (with added MinLineHeight=0) and my own settings. I really don't know what else I should try, I spent so many hours on this that I couldn't add many new functions this week.

Strange but fixed in TC 9.0b10 x64!

Just for the record:

Perfectionism is state of mind, maybe therefore so much time... Thank you for your effort.

[ghisler(Author)]

Strange, I'm not aware of any changes between beta 9 and 10 which would fix that. It should have been fixed already in beta 9...

Yes, strange. Perhaps this change had an effect on this error:

Code: Select all

14.08.16 Added: Re-added horizontal border between listbox and footer when using themes, using top line of tab control (32/64)

I don't know if you want to spent another time on this, but I recorded how to get this error with Licecap (gif file, IrfanView handles it correctly).
You can find it here: https://en.webshare.cz/#/file/4a538n1dp1/tc9-b9-tab-error-zip

Keystrokes are visible in virtual keyboard. Not all mouse clicks are recorded, but important is that right panel can get focus with mouse double click and pressing Down, Up, Down, Right crashes TC. With clean ini (with MinLineHeight=0) Tab key doesn't work too, but crash isn't so quick.

I tried it with my config on 3 different PC's (all Win7 64-bit) and error was 100 % repeatable with TC9 b9 64-bit.
So here is my wincmd.ini with relevant sections (MIME encoded):
