[Solved] Java: how to set data in a TreeControl?

[milek_pl]

Hi all,

I'm trying to set data for a TreeControl in a saved dialog. I have absolutely no idea how to link XTreeControl and the tree data. I see no methods for doing this, so probably there is something obvious I'm overlooking. This is the code I have:

Code: Select all

     Object xTreeData = xMCF.createInstanceWithContext(
           "com.sun.star.awt.tree.MutableTreeDataModel", xContext);
     XMutableTreeDataModel mxTreeDataModel = (XMutableTreeDataModel) 
       UnoRuntime.queryInterface(XMutableTreeDataModel.class, xTreeData); 
     XMutableTreeNode xNode = mxTreeDataModel.createNode("test1", false);
     xNode.setDataValue("test2");
     xNode.setExpandedGraphicURL(sPackageURL + "triangle_down.png");
     xNode.setCollapsedGraphicURL(sPackageURL + "triangle_right.png");
     mxTreeDataModel.setRoot(xNode);
     XTreeControl mxTreeControl = (XTreeControl) 
     UnoRuntime.queryInterface(XTreeControl.class, xDlgContainer.getControl("Rules"));
     Object xTreeConM = xMCF.createInstanceWithContext(
         "com.sun.star.awt.tree.TreeControlModel", xContext);
     XControlModel xTreeControlModel = (XControlModel)
       UnoRuntime.queryInterface(XControlModel.class, xTreeConM);
     XPropertySet xTreeControlModelSet = (XPropertySet) UnoRuntime.queryInterface(XPropertySet.class, xTreeControlModel);
     xTreeControlModelSet.setPropertyValue("DataModel", mxTreeDataModel);

So I created data for the TreeDataModel etc., but there is no setting method for XTreeControl that I got from the dialog. My code throws no null exception so it seems to work fine but of course nothing displays. Any idea what I'm doing wrong?

Hi,

You don't need to make a new control model and get it from the control taken by the getControl method if it is created by the dialog editor.

Code: Select all

		// get the XControlModel of the tree control
		XControl xControlTree = xDlgContainer.getControl("Rules");
		XControlModel xTreeModel = xControlTree.getModel();

		Object xTreeData = xMCF.createInstanceWithContext(
          		 "com.sun.star.awt.tree.MutableTreeDataModel", xContext);
		XMutableTreeDataModel mxTreeDataModel = (XMutableTreeDataModel) UnoRuntime.queryInterface(
				XMutableTreeDataModel.class, xTreeData);

		XMutableTreeNode xNode = xDataModel.createNode("Root", false);

		xDataModel.setRoot(xNode);

		XPropertySet xTreeModelProperty = (XPropertySet) UnoRuntime.queryInterface(
				XPropertySet.class, xTreeModel);
		xTreeModelProperty.setPropertyValue("DataModel", xDataModel);

Thanks! This made it work. I tried using XTreeControl but it has no getModel() method...
