TC window lost focus -> deselection in virtual folders

[DrShark]

To reproduce:
1. Select some items in virtual \\Desktop (cm_OpenDesktop) or \\Computer folder.
2. Make TC window to lost focus, and then restore it (Alt+Tab -> Alt+Esc, Minimize->Restore, Start/Close Search in separate process etc...):
selection lost even if virtual folder with selected items is in inactive panel.

Reproduced both with default settings and with colon (:) in the "No refresh for these drives:" option on Configuration->Refresh settings page.

Note: it's possible to restore selection lost in such case by activation of panel with virtual folder and using Mark->Restore Selection (cm_RestoreSelection) there.

This happens because TC re-reads the virtual folder. There is no easy way to determine whether it was unchanged or not, because internal virtual folder data can change.

This happens because TC re-reads the virtual folder.

The refresh happens even after a return of a focus to TC with TC option Configuration->Refresh->Auto-refresh when activating the program->No refresh for these drives: set to : (means TC shouldn't refresh virtual folders after window activation.) Maybe there is a bug in this function?

OK, but maybe it won't be a bad solution at least to auto-restore the selection (using cm_RestoreSelection method) after refresh+selection loss happens in a virtual folder if virtual folder was opened at least in one panel but no active action was done by user before refresh happened?

Why this topic moved to "Behaviour which will not be changed" subforum? TC option Configuration->Refresh->Auto-refresh when activating the program->No refresh for these drives: set to : should tell TC not to refresh virtual folders, yet still in described case TC re-reads and refreshes it. If it is not a bug, than what it is?

Because it's not possible to reliably detect whether a virtual folder was changed or not. I can't just compare the ID lists because their content can change although the item itself doesn't.

The option Configuration->Refresh->Auto-refresh when activating the program->No refresh for these drives: set to : (colon) is telling Total Commander NOT to refresh the virtual folders on TC window activation, no matter whether they was changed or not. But TC still refreshes virtual folder in such a case.

It shouldn't do this with noreread=: - I will check it.

07.05.18 Fixed: Configuration - Options - Refresh - "No refresh for these drives" didn't work correctly for virtual folders: ':' should disable refresh, but instead, '\' was used (32/64)

It works now on \\Desktop\, but doesn't seem to work on \\Computer\: open \\Computer\, minimize TC [to tray]->connect usb drive->restore TC: \\Computer\ will be refreshed, new drive letter will appear.

07.05.18 Fixed: Selection was always lost in virtual folders like the Desktop when switching away from TC and back, even when nothing changed (32/64)

On this change, which fixes not only deselection, but also a cursor jump issue, I wrote a feedback here: viewtopic.php?p=340824#340824

"Computer" is handled separately.
