cm_rereadsource & Selected files

[Galizza]

 
Hi, if i use cm_rereadsource on a panel with several files selected Tc don't
unmark them, but when i use cm_rereadsource 1 then selected files are
unmarked, may you consider a new option like cm_rereadsource 4
that force a refresh but without unmarking any file ?, thanks

What is important, the selection is not only reset, but also not restored. A bug?

Code: Select all

cm_RereadSource 1,cm_RestoreSelection

You can do this: cm_SaveSelection,cm_RereadSource 1,cm_RestoreSelection.

You can do this: cm_SaveSelection,cm_RereadSource 1,cm_RestoreSelection.

Thank you

Hi, if i use cm_rereadsource on a panel with several files selected Tc don't unmark them..

Then TC detected nothing had changed in that folder and didn't do a refresh.

..but when i use cm_rereadsource 1 then selected files are unmarked

In this case you forced a refresh and the selected files are unmarked.

What is important, the selection is not only reset, but also not restored. A bug?

Code: Select all

cm_RereadSource 1,cm_RestoreSelection

Yes, I believe there is one.
Apparently Auto-Refresh when activating the program does save the selection, but a manual refresh doesn't save the selection.

• Mark files 1, 2 and 3
• Press CTRL+NUM - (deselect all) (selection is stored implicitly)
• Mark files 4, 5 and 6
• Execute cm_RereadSource 1
• Press NUM / (restore selection)

Now files 1, 2 and 3 are marked.
If you can't restore the last selection after a refresh, it's weird for the user that an earlier selection is restored instead.

Auto-Refresh when the file system changes - Selection is not lost.
Auto-Refresh when activating the program - Selection is lost but saved.
Manual Refresh - Selection is lost and not saved.

Press CTRL+NUM - (deselect all) (selection is stored implicitly)

This is a false assumption, the selection is only saved if some sort of action takes place that clears the list. Such an action could be pressing Ctrl+NUM - (but not pressing NUM- -> * -> Enter (cm_ShrinkSelection) for some reason).

Try and replace Execute cm_RereadSource 1 in your example above with: cm_ShrinkSelection - same outcome.

What is the reason for moving the topic? It would be logical to fix it.

[ghisler(Author)]

cm_rereadsource does nothing if it detects that the folder wasn't changed. Therefore the selection is preserved. However, if something changes, or you force a refresh via cm_rereadsource 1, then the current file list is removed and replaced by the new one read by cm_rereadsource. This also removes the current selection.

[Fla$her]

then the current file list is removed and replaced by the new one read by cm_rereadsource.

Where does he get this new list from? And why did you need to do this? What's the point of deleting a list from memory?

[ghisler(Author)]

cm_rereadsource reads the file list of the current directory, then checks if its checksum is the same as that of the currently displayed list. If they are the same, the displayed list isn't refreshed to avoid flickering. If they not the same, the old list is discarded and the new one is shown.

Please read the thread again. From second post onwards it's about not being able to restore the selection.

Apparently Auto-Refresh when activating the program does save the selection, but a manual refresh doesn't save the selection.

• Mark files 1, 2 and 3
• Press CTRL+NUM - (deselect all) (selection is stored implicitly)
• Mark files 4, 5 and 6
• Execute cm_RereadSource 1
• Press NUM / (restore selection)

Now files 1, 2 and 3 are marked.
If you can't restore the last selection after a refresh, it's weird for the user that an earlier selection is restored instead.

Auto-Refresh when the file system changes - Selection is not lost.
Auto-Refresh when activating the program - Selection is lost but saved.
Manual Refresh - Selection is lost and not saved.

Yes, yes. It's not about resetting the list, but about what I wrote:

What is important, the selection is not only reset, but also not restored.

[ghisler(Author)]

cm_RestoreSelection only works when the previous selection was stored, which only happens in file operations, e.g. when you copy something and the selection gets removed. That's why you have to call
cm_SaveSelection,cm_RereadSource 1,cm_RestoreSelection

[Fla$her]

When we execute cm_RereadSource, the panel is redrawn, this can be seen by tabs. The selection is not lost.
If we remove the selection by Ctrl + [-], then we can easily return it by pressing [/].
Why does resetting the allocation by hotkey not delete the allocation list from memory, but the one called by cm_RereadSource 1 does? Why can't you get rid of it?

cm_RestoreSelection only works when the previous selection was stored, which only happens in file operations, e.g. when you copy something and the selection gets removed.

Not true, as I just mentioned above:

Press CTRL+NUM - (deselect all) (selection is stored implicitly)

Auto-Refresh when activating the program - Selection is lost but saved.

It's like petermad says:

.. the selection is only saved if some sort of action takes place that clears the list. Such an action could be pressing Ctrl+NUM -

Manual refresh is an exception causing confusing behavior:

If you can't restore the last selection after a refresh, it's weird for the user that an earlier selection is restored instead.
