Bug ID: 447365
Summary: Side menu buttons disappear and stay invisible after
switching globalToolBar.style from None to any other
value and back to None
Product: frameworks-kirigami
Version: 5.86.0
Platform: Compiled Sources
OS: All
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: notm...@gmail.com
Reporter: javiercorderope...@gmail.com
Target Milestone: Not decided
SUMMARY
Side menu buttons, used to access global and context menus, disappear and stay
invisible after switching globalToolBar.style from None to any other valid
value and back to None.
STEPS TO REPRODUCE
1. Assign `pageStack.globalToolBar.style` to a condition where
`Kirigami.ApplicationHeaderStyle.None` is the initial value.
> property bool toggleMeValue: false
> pageStack.globalToolBar.style: toggleMeValue ?
> Kirigami.ApplicationHeaderStyle.Titles : Kirigami.ApplicationHeaderStyle.None
2. Provide a way to change the previous condition, so that any other style is
used.
> MouseArea {
> anchors.fill: parent
> onClicked: toggleMeValue = !toggleMeValue
> }
3. Run the program. Toggle from None to alternate style, see menu buttons
disappear as intended.
4. Toggle from alternate style back to None, buttons will be re-instantiated
but they will not be visible.
OBSERVED RESULT
Kirigami menu buttons disappear and return as intended, but will remain
invisible upon returning.
EXPECTED RESULT
Kirigami menu buttons should be visible upon being re-instantiated.
SOFTWARE/OS VERSIONS
Windows: Windows 10 Craft with MSVC compiler
macOS: macOS Monterey Craft with Clang x86 compiler
Linux/KDE Plasma: KDE Neon Craft with both GCC and Clang compilers
Android: Android 12, with GCC compiler
KDE Plasma Version: 5.23.4 (testing branches, host Linux system)
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.2 and 5.15.3
ADDITIONAL INFORMATION
When using Qt's Material theme, a shadow is visible where the buttons are
placed, but the buttons themselves remain invisible. Under Plasma Mobile there
are no shadows surrounding the buttons, therefore when the buttons return,
there is no way to tell they've been re-instantiated.
