How can I read property values set in QtDesigner for a custom widget?
I am trying to create a new custom widget that can be used from QtDesigner. My new widget has its own properties declared in the class header...
Q_PROPERTY(QString nodeId READ nodeId WRITE setNodeId)
I added the property to the domXml() string...
... " <property name=\"nodeId\">\n" " <string>ns=4;s=device.sensor.value</string>\n" " </property>\n" ...
I then created an application that uses the widget. I drag the widget onto the main window. I set the property values using the property editor in QtDesigner.
I can see that when the widget is instantiated that the property values are not set to those I configured in QtDesigner. Therefore I suppose I have to read the values from the application UI XML document and set them by myself in the constructor. Is this correct? Can anyone explain how I can read these values in the constructor?
I see in the Ui_MainWindow.h that my widget is instantiated and then the properties are set in the setupUi() method. I can now see my properties are being set with values configured in QtDesigner. This is good. No further help required. Thanks.
