[video attached] Wrong activity when selected folder/file and pressing Shift/Ctrl with Left/Right/PgUp/PgDn/Home/End

Post by forklab »

XnView MP Windows 0.98.2 x64 and all versions last year.
This bug was all the time I'm using XnView MP. Win7 x64, Win10 x64 - no matter.

It's very strange activity of the program when:
1) Find a folder where are so much files/folders that last row will be not fully filled.
2) Select any of the file or folder at the column where are last row has a picture. If select a file under free space at last row it will work another way.
3) Press Ctrl-PgUp/Ctrl-PgDn (Ctrl-Left/Ctrl-Right).
at this moment something happens - backgroung picture of selected file/folder changes (if css-stylesheets for that element different enough to see)
4) we can press 1-2-3 and more times Ctrl-PgUp/Ctrl-PgDn (Ctrl-Left/Ctrl-Right) then press Left/Right after that -

If we pressed Ctrl-PgUp/Ctrl-PgDn before Left/Right then our cursor will inadequately jump to the first/last line of files/folders and to the left or right of the column of our previously selected file. If we pressed Ctrl-Left/Ctrl-Right n-times and then Left/Right then we will jump with selection to the file/folder that was n-times left/right to our selected file.

Correct behavior would be and must be like that:
1) If we presses Ctrl-PgUp/Ctrl-PgDn then selection is not changed but our view jumps 1 page upper or 1 page lower. And after pressing Left/Right we must jump to view where we see our previously selected file/folder but our selection must be 1 file/folder to the left or to the right depending on which button we pressed.
2) If we presses Ctrl-Left/Ctrl-Right then selection is not changed and our view not changed because we have no horisontal scroll. Pressing Left/Right must be as at 1)

PS: when we edit filename of selected file and press Ctrl-PgUp/Ctrl-PgDn then editing is cancelled (it's not correct, I must continue to edit filename) and all everything the same as before.

By using Ctrl+Left/right/up/down, you change the current focus but not the current selection

Lot of the programs (most I've used for 30+ years) uses Ctrl-Left/Right/Up/Down/PgUp/PgDown to leave selection where it is but scroll visible area to according number of lines/pages.

Using XnView with keyboard is always a pain.
Please, fix this bugs.
Just enter to the directory with pics (morethan one screen - better) and try to use keys Left/Right/Up/Down/Home/End/Backspace and use modificator keys - Shift/Ctrl/Alt. There is no need to write a long description of what will happen. Just try any keys and combinations, try to select with Shift/Ctrl to the left-right-up-down-end-start etc, and see with your own eyes. Sometimes there is a strong desire to break something or kill someone.

PS: it's not for that topic, but I don't want to create new topic for this (too small problem):
.zip and .exe contents at downloads page always differs from each other, few years as I watch. And between XnConvert and XnViewMP too.
For example - "plugins\qml" dir contents & and "qml\QtQuick\Controls", "AddOn\ICCProfiles", "languages", "plugins\imageformats" etc.

PPS: ontopic. Seems like you fixed this (don't know all or not, will use some time and if something will be wrong - I'll reply here), but in the WhatsNew.txt I think you write wrong text - #1420, Bug, "Selection... is inconsistent" and topic #34297. But reading that topic shows that reported there are not full report and bugtracker shows that it was fixed in 2018... So maybe WhatsNew.txt #1420 link must be corrected to this topic?

Thanks for everything.

Is there any progress?
Just tested it now in 1.5.3:
1) entered dir with almost full one row of pictures, 6 jpegs & 1 png
2) Shift-End - seems like all files selected, Shift-Home, Shift-End, Shift-Home few times - seems ok
3) End (png selected), Shift-Home, Shift-End, Shift-Home, Shift-End - seems ok
4) Home, Shift-End - oops, selection is broken, selection jumped to the last png without selecting all files
5) Home, Shift-Right - crazy selection - selected all files except first
And so on...

I cannot reproduce in 188

however, there is issue with Shift+PgUp/PgDn
1. prerequisites
- open folder with 25 files in Browser
- resize app window to show 9 thumbnails in 3x3 grid
2. select 2nd file in the 1st row (or 2/3 row)
3. hold Shift and press PgUp/PgDn multiple times until you reach the end
last file will not be selected

expected behviour
holding Shift and pressing PgUp/PgDn multiple times should select all files till the beginning/end of the folder

Yes, 1.8.8 - still an issue, nothing changed (every version every installation every machine)

I recorded it to a video.
It makes no difference whether XnView MP is installed directly via setup, as a portable or via winget. On any PC I've installed it on, in any version, there is always this bug (for me - always, from the first version I got acquainted with, and that was a looong time ago)

I've tried to make:
- left click to remove selection
- Home
- End
- Home
- Shift + End, and here all files are selected. If i understand your video, you have not the same thing?

Try to reproduce on clean version with default settings (it does look like you customized something).
Try to resize app window and reproduce as it affects result in my case.
Make sure your desired behaviour is the same as in windows file explorer.
