Basic qml label update with cpp

[MaxBec]

Hey guys,

i have a pretty simple question but i dont find a solution:

I want to update this qml component when the property ACSQmlTool.linkTool.isConnected changes:

Label {
	id:                      connectionLost
	text:		         ACSQmlTool.linkTool.isConnected ? qsTr("Link connected!") : qsTr("Link disconnected")
	font.pointSize:		 ScreenTools.defaultFontPointSize
	font.family:		 ScreenTools.normalFontFamily
	font.weight:		 Font.Normal
	color:			 ACSQmlTool.linkTool.isConnected ? ACSPalette.lightblueLight : ACSPalette.orange
	visible:		 ACSQmlTool.linkTool.isConnected
}

Unfortunately it doesn't change even if the property changes.

@MaxBec hi
what is that ACSQmlTool ? how it is exposed to qml ?

@MaxBec said in Basic qml label update with cpp:

even if the property changes.

how do you check that ?

LinkTool:

class ACSLinkTool : public ACSAbstractTool
{
		Q_OBJECT

	public:
		ACSLinkTool(ACSApplication* app, ACSToolbox* toolbox);
		~ACSLinkTool();

		Q_PROPERTY(bool						isBluetoothAvailable		READ isBluetoothAvailable		CONSTANT)
		Q_PROPERTY(ACSQmlListModel*				linkConfigurations			READ _qmlLinkConfigurations		NOTIFY linkConfigurationsChanged)
		Q_PROPERTY(QStringList					linkTypeStrings			READ linkTypeStrings			CONSTANT)
		Q_PROPERTY(QStringList					serialBaudRates			READ serialBaudRates			CONSTANT)
		Q_PROPERTY(QStringList					serialPortStrings			READ serialPortStrings			NOTIFY commPortStringsChanged)
		Q_PROPERTY(QStringList					serialPorts				READ serialPorts				NOTIFY commPortsChanged)
		Q_PROPERTY(bool						isConnected				READ isConnected				NOTIFY isConnectedChanged)

QmlTool:

qmlRegisterSingletonType		<ACSQmlTool>				("ACSCpp.Qml",				1, 0, "ACSQmlTool",				qmlToolSingletonFactory);

isConnected is directly changed in the code for debug purposes.

did you emit isConnectedChanged() signal when you write the new value?
