Description illumilore 2011-08-05 20:10:20 UTC

Version:           unspecified (using KDE 4.7.0) 
OS:                Linux

When resizing a panel, it is possible to drag the panel resize arrows and move them to the arrows on the other side of the panel, making the panel zero size and making it disappear with no way to reopen it and losing all changes made to that panel and the panel itself.

Reproducible: Always

Steps to Reproduce:
see above

Actual Results:  
see above

Expected Results:  
see above

Can't confirm that on KDE 4.7.2. There is small but adequate minimal size even with empty panel

Comment 2 Reza 2011-11-25 09:51:34 UTC

Just tried with latest master.

It happened when the panel was resized using the most left slider dragged to the right side of screen.
And this problem didnot appear when the panel resized using the most right slider dragged to the left side of screen.

so we don't lose this bit of information:

[11:29] <rshah> aseigo: regarding this bug 279482, the broken file was plasma-desktop-appletsrc
[11:30] <rshah> the value at containment for panel was geometry=0,-34,0,28

Comment 4 Pieter Vande Wyngaerde 2011-12-03 13:52:28 UTC

(From irc #plasma) pingupingu: a very very quick look at the panelcontroller.cpp. there seems to be a static const int MINIMUM_HEIGHT = 10; line 79, shoudlnt there be one like this for the width too? so you cant get the width down to 0?
