Hi all,

I am new to QML and I am currently working at a reusable QML component.
It is a ListView with a model class attached.
The model is derived from QStandardItemModel with custom roles defined.
Furthermore, the ListView uses a delegate component to render the data attached to the role.
As I have got several model sub classes I would like to reuse my ListView with different models which in the end all define different roles.
So far, everything works fine except re-use.

In order to reuse my ListView I think I have to assign roles more dynamically e.g. configure the role the delegate should use for rendering from outside of my ListView component.

Here is a short example of what I would like to achieve:

main.qml:

Qt Code: 
  1. Rectangle
  2. {
  3. 	MyListView
  4. 	{
  5. 		id: taskList
  6.  
  7. 		model: taskModel //QStandardItemModel
  8. 		role: CustomDisplayText//<-role assignment does not work this way
  9. 	}
  10. }

MyListView.qml:
Qt Code: 
  1. MyListView
  2. {
  3.         id: myListView
  4.         objectName: "myListView"
  5.         property variant role
  6.  
  7.  
  8.         delegate:   Rectangle
  9.                     {
  10.                         id: itemDelegate
  11.                         objectName: "itemDelegate"
  12.  
  13.                         color: itemDelegate.focus? highlightColor : backgroundColor
  14.  
  15.                         Text
  16.                         {
  17.                             id: itemTextField
  18.                             objectName: "itemTextField"
  19.  
  20.                             anchors.verticalCenter: itemDelegate.verticalCenter
  21.  
  22.                             text: role
  23.                         }
  24.  
  25.                         MouseArea
  26.                         {
  27.                             id: itemDelegateMouseArea
  28.                             objectName: "itemDelegateMouseArea"
  29.                             anchors.fill: parent
  30.                             onClicked:
  31.                             {
  32.                                 itemDelegate.forceActiveFocus();
  33.                                 itemSelected(model.index)
  34.                             }
  35.                         }
  36.                     }
  37. }

In fact, the role assignment does not work this way.

Can anyone help me solving my problem?

Thanks in advance!
