Created attachment 4464 xfce4-diskperf-plugin-border.patch The defined "BORDER" is used for various widgets, even in the configuration dialog, and I think it's cleaner to rework this a little. Why should someone expect the plugin border of a configuration dialog widget or the sizes of the progress bars be influenced when trying to change the border of the main plugin box or vice-versa? Therefore define the plugin border, label border and progress bar size separately and optimize the label border to be consistent with other plugins (label spacing 2px), and not making the label look 'stuck' to the progress bars. Note: The some_BORDER variables now represent the real values of the border, you don't have to calculate them by dividing the value or do other calculations.
I think this has been mostly implemented in http://git.xfce.org/panel-plugins/xfce4-diskperf-plugin/commit/?id=c155f4c6c9822c087dabe71e454fc0243454d504 .. harald, maybe we can close this bug ? Or there are more tweaks to apply ?
Yes, I think so. Looks fine to me.
Closing.
