Hi Jia, The error you are getting is that the HAL component signature does not match the remote version of the HAL remote component. In your case this probably means that the HalLeds are created after the HalApplicationWindow component searches for HalPins in its child items.
In this case it might be necessary to use a ServiceWindow instead. The HalApplicationWindow is convenience Component that combines a HalRemoteComponent and a ServiceWindow. You cannot control when the HalRemoteComponent looks for pins in this case. So the way to do this would be to create a ServiceWindow (see BasicQtQuickVcp for an example) and a HalRemoteComponent (you can take a look at the HalRemoteComponentWindow implementations itself for a reference: https://github.com/machinekoder/QtQuickVcp/blob/master/src/halremotecontrols/HalApplicationWindow.qml#L296) and then set ready property of the HalRemoteComponet with Component.onComplete of the top level ServiceWindow. This ensures that the HalRemoteComponent is started after the Repeater does its work. -- Alexander maxh...@araisrobo.com writes: > Hi Alexander , > > Yishin and I are the same team. > The question now, HAL can not correct link. > The following source code: > Tab { > id: signaltab > anchors.top:parent.top > title: qsTr("Signals") > active: true > > HalApplicationWindow{ > id: main > title: "My HAL application" > name: "signals" > > Repeater { > model: 8 > HalLed { > name: "gpio.in." + index > } > } > } > } > > > Jia li > > Alexander Rössler於 2015年9月9日星期三 UTC+8上午9時46分41秒寫道： >> >> Actually Machineface uses a Repeater to create some user interface >> elements: >> >> https://github.com/strahlex/Machineface/blob/master/Machineface/DisplayPanel.qml >> >> >> The key is that the Repeater needs to be loaded at start-up.
