Summary: Kirigami.Icon in custom compactRepresentation absorbs mouse events,
preventing parent Item MouseArea from receiving clicks over the icon area
Description:
When implementing a custom compactRepresentation that contains a Kirigami.Icon
alongside other items (e.g. a PlasmaComponents.Label), the Kirigami.Icon
silently absorbs mouse events. This prevents the parent Item's MouseArea (with
anchors.fill: parent) from toggling the plasmoid's expanded state when clicking
over the icon area.
The KDE documentation states: "If you modify the compact representation, you
must use a MouseArea QML Item to toggle the plasmoid.expanded property."
However, even with a correctly placed MouseArea on the root Item, clicks on the
Kirigami.Icon area are absorbed and do not reach the MouseArea.
Steps to reproduce:
Create a plasmoid with a custom compactRepresentation containing a
Kirigami.Icon and a PlasmaComponents.Label inside a RowLayout
Place a MouseArea with anchors.fill: parent on the root Item
Click on the icon portion of the compact representation — the popup does not
toggle
Click on the label portion — the popup toggles correctly
Expected behaviour:
Clicking anywhere within the compact representation should toggle the plasmoid
popup, consistent with the documented MouseArea approach.
Actual behaviour:
Only the area not covered by Kirigami.Icon registers clicks. The icon area
absorbs mouse events without forwarding them.
Workaround:
Add a second MouseArea directly inside the Kirigami.Icon element in addition to
the root Item's MouseArea:
compactRepresentation: Item {
implicitWidth: compactRow.implicitWidth + 12
implicitHeight: compactRow.implicitHeight
MouseArea {
anchors.fill: parent
onClicked: root.expanded = !root.expanded
}
RowLayout {
id: compactRow
anchors.centerIn: parent
Kirigami.Icon {
source: Qt.resolvedUrl("../icons/mywidget.svg")
implicitWidth: 22
implicitHeight: 22
MouseArea {
anchors.fill: parent
onClicked: root.expanded = !root.expanded
}
}
PlasmaComponents.Label {
text: "some text"
}
}
}
See also bug 416311 (CompactRepresentation's MouseArea intercepts hover
event) — related MouseArea/Kirigami.Icon interaction issue in the same
code area, marked RESOLVED FIXED. Click event absorption appears to be
a separate unresolved regression from the same root cause.
