Bug ID: 384408
Summary: PanelView::setBackgroundHints doesn't update
enabledBorders (which means it doesn't toggle the
shadows)
Product: plasmashell
Version: 5.10.5
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: minor
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: zrenf...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
While fussing with /usr/share/plasma/shells/.../contents/views/Panel.qml, I
tried dynamically disabling the blur+shadows on the panel (using a repeating
timer). I noticed that while the blur effect went away, the shadows did not.
QML:
panel.backgroundHints = Plasma.Types.NoBackground
C++: https://github.com/KDE/plasma-workspace/blame/master/shell/panelview.cpp
setBackgroundHints(Plasma::Types::NoBackground)
emit backgroundHintsChanged()
connect(this, SIGNAL(backgroundHintsChanged()), this, SLOT(themeChanged()));
themeChanged() calls updateMask() but doesn't call updateEnabledBorders().
updateEnabledBorders() is what disables the panel shadow.
PanelView::resizeEvent and PanelView::moveEvent call both "update" functions,
so
You can test this by editing Panel.qml. Note that "panel" == PanelView.cpp.

I did try resizing the panel, and the shadow did dissappear. However it did not
reappear when I resized it again.
