Description aslam karachiwala 2019-03-23 20:08:37 UTC 
SUMMARY
With the 'Hide sidebars' setting checked under Views->Full-Screen, the sidebars revert to their respective default widths if one switches to full-screen, after changing the sidebar width(s), then switches back to window view. If 'Hide sidebars' is unchecked then the sidebars do retain their widths after switching back from full-screen to window view.

STEPS TO REPRODUCE
1. Menu selection Settings->Configure digiKam...
2. In Configuration window, go to Views->Full-Screen tab.
3. In Views->Full-Screen tab, enable 'Hide sidebars'.
4. Click OK button at the bottom; this will close the Configuration window.
5. Alter the widths of the left and right sidebars by dragging their respective boundaries.
6. Switch to full-screen view.
7. Leave the full-screen view.

OBSERVED RESULT
The sidebars have their respective default widths.

EXPECTED RESULT
The sidebar widths are those set in #5 above.
