Description
I've QML code like this:
onClicked: {
if (panelGrid.currentPageIndex === 0) {
panelGrid.currentPageIndex = panelGrid.pages - 1
} else {
panelGrid.currentPageIndex -= 1
}
}
The first branch of the "if" is generated to:
// generate_Decrement
{
auto converted = QJSPrimitiveValue(r2_4);
r2_2 = --converted.toInteger();
}
Which turns to:
src/app/com/foo/ui/.rcc/qmlcache/foo_ui_pages/panel/PanelArea_qml.cpp: In lambda function:
src/app/com/foo/ui/.rcc/qmlcache/foo_ui_pages/panel/PanelArea_qml.cpp:4246:29: error: lvalue required as decrement operand
4246 | r2_2 = --converted.toInteger();
| ~~~~~~~~~~~~~~~~~~~^~
~~~~~~~~~~~~~~~~~~^~
There's a similar one with:
if (panelGrid.currentPageIndex === panelGrid.pages - 1) { panelGrid.currentPageIndex = 0 } else { panelGrid.currentPageIndex += 1 }
but the comparison turns to:
src/app/com/foo/ui/.rcc/qmlcache/foo_ui_pages/panel/PanelArea_qml.cpp: In lambda function:
src/app/com/foo/ui/.rcc/qmlcache/foo_ui_pages/panel/PanelArea_qml.cpp:4473:28: error: lvalue required as decrement operand
4473 | r2_2 = --converted.toDouble();
| ~~~~~~~~~~~~~~~~~~^~
PanelGrid is a qml component where pages is
property alias pages: gridRepeater.model
and gridRepeater.model is a number
Repeater {
id: gridRepeater
model: 4
