Thumbnails are not automatically generated.

Post by FKCapitalism2 »

Related to this bug report, perhaps also this one.

Right now in 1.4.5 i like how XnView MP started to automatically generate thumbnails for folders that got created by script (ExifTool) while XnView MP interface is open, also XnView MP recognizes folders created inside windows explorer when XnView MP interface is closed and upon opening generates thumbnails for newly created folder, fantastic finally it works.

1st issue. When inside XnView MP thumbnails view inside folder c:\images\ i create folder "car" (c:\images\car) (F7 key) then paste/move images into c:\images\car and navigate one folder up, thumbnails for folder "cars" are not generated.

If i navigate to c:\images\ create folder "car" (F7 key) while still staying inside folder c:\images\ i drag and drop images info folder "car" trough XnView MP interface - thumbnails also are not generated.

Even if i restart XnView MP thumbnails not generated for folder c:\images\car, only if i turn off XnView MP and then rename folder c:\images\car to "c:\images\car2" in windows explorer and start XnView MP then thumbnails for folder "car2" are getting automatically generated.


2nd issue, when using XnView MP interface i move ALL images out of the folder c:\images\car2 (Ctrl+X) into one folder up c:\images\ (Ctrl+V) folder c:\images\car2 is still showing thumbnail icons as if images are there, however folder is empty.

i have no way to know that a folder content has changed, so you need to use 'Rebuild thumbnail' on the folder

After each copy/move action you can query the folder where files were copied and see IF no thumbnails exist THEN generate thumbnails for that folder.

Same for moving files out of the folder after move command or Ctrl+X Ctrl+V query path where the files moved from and check IF no files left inside that folder THEN clear thumbnails.
