Bug ID: 523088
Summary: Language key always opens a selection dialog; with
only two enabled languages it should toggle directly
Classification: Plasma
Product: Plasma Keyboard
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
STEPS TO REPRODUCE
1. System Settings -> On-Screen Keyboard -> enable exactly two languages (e.g.
German + Russian)
2. On a convertible, detach the keyboard (tablet mode) and focus a text field
so the on-screen keyboard appears
3. Tap the language (globe/earth) key
OBSERVED RESULT
A language selection dialog opens and you have to tap the wanted language.
Every single language switch costs two taps, even though there is only one
other
language to switch to.
EXPECTED RESULT
With exactly two enabled languages, a tap on the language key should switch
straight
to the other language, without a dialog. The dialog only adds value with three
or more
languages (and could stay there, or move to a long-press).
ADDITIONAL INFORMATION
plasma-keyboard sets externalLanguageSwitchEnabled: true on the InputPanel and
always
routes the key press to the dialog:
externalLanguageSwitchEnabled: true
onExternalLanguageSwitch: (localeList, currentIndex) => {
languageDialog.show(inputPanel.keyboard.activeKey, localeList,
currentIndex)
}
Without that flag, Qt Virtual Keyboard's built-in handler cycles to the next
enabled
language on a single tap - which is exactly the desired behaviour for two
languages.
Suggested fix (any of):
- Set externalLanguageSwitchEnabled: false when
PlasmaKeyboardSettings.enabledLocales.length <= 2
- Or in onExternalLanguageSwitch: if localeList.length === 2, switch directly
instead of showing the dialog
- Or generally: tap = cycle to next language, long-press = show the dialog
There is no user-facing setting for this - plasma-keyboard only knows
enabledLocales and
panelFillScreenWidth; the KCM offers just "Languages" and "Key press feedback".
