Columns won't keep size in 5.39 - Page 2

chaley · 03-19-2022, 08:36 AM

@kovid: the problem happens because gui2.library.views.restrict_column_width() is called before the main window is resized. At startup the (undisplayed) main window appears to be 100px wide so the calculation of the maximum space available for a column is incorrect. The sizes don't become correct until all the various events are processed, which is at the end of initialization.

I have a fix but I worry that it is not optimal or even correct. I changed restrict_column_width() to do nothing until all of the events to repaint the screen are processed (the same as quickview initialization). This required added an "initialization_complete" boolean to ui.py that restrict_column_width() checks. I can push a PR with these changes if you want to see them.

Edit: restrict_column_width() appeared with pin views.

Edit 2: my guess is that Qt changed how and when some resize and repaint events are processed.

EDIT: see post 19 below

??? Is this only happening if you resize a column in a session?
5.39 win10 x64

because the existing size ( set from 5.38) is being maintained

It is resized, made smaller, if the existing size is larger than somewhere around 260 pixels. The view manager plugin fixes the sizing.

@kovid: Never mind post 16. It is caused by my change to library.views.apply_state(). I am testing a fix that maintains the improved performance.

EDIT: PR pushed.

So it's either back to 5.38 or jump to beta?
5.39 on Windows 10 only remembers column size on one library and forgets it for my other 3.
No, the libraries are not on a network drive, only on second HDD.
No, I don't use view manager.

It is back to 5.38. The latest beta contains the regression. [It doesn't, but that is irrelevant now that 5.39.1 is released. I accidentally tested running from source.]

The regression causes columns above a certain size to be reduced when calibre starts. They aren't reduced when you use switch library.

Is there going to be a 5.39.1 with the fix?

I will gladly stick with 5.39 anyway. Not having the Saved Search window blow up on me every time I fidget with it surely compensates for modifying that Title column in the book list back to normal.

The view manager plugin works around the problem by applying column sizes after calibre initializes. If you set up a default 'apply on start up' view then the sizes in that view will win.

Or wait ...

This plus the title case problem might be enough for Kovid to decide to do a 5.39.1 point release.

EDIT: @JSWolf: there will be a point release if Kovid thinks it is worth it.

What is the title case problem?

See the 7th post in the calibre forum..
