Figure 5-4. The model shown in a tree view, with the second row opened to show the child items Before the small example application shows the model, you must tell the views what model to use by using the setModel(QAbstractItemModel*) method, as shown in Listing 5-3. Listing 5-3. Setting the model for all views tree->setModel( &model ); list->setModel( &model ); table->setModel( &model ); Although setting the model is all that s required to get things up and running, I want to demonstrate the differences between the models using the selection model, so there is one more step to perform before you continue. The selection model manages selections in a model. Each view has a selection model of its own, but it is possible to assign a model using the setSelectionModel(QItemSelectionModel*) method. By setting the tree s model in the list and the table, as shown in Listing 5-4, selections will be shared. This means that if you select something in one view, the same item will be selected in the other two as well. Listing 5-4. Sharing the selection model list->setSelectionModel( tree->selectionModel() ); table->setSelectionModel( tree->selectionModel() ); Wrapping all this in a main function along with a QApplication object gives you a working application that can be built with QMake. Figures 5-3 and 5-4 show the running application. There are a number of things for you to try out in the application that can teach you something about how the models and views work in Qt:

Try picking one item at a time in any one of the views and study where the selection is shown in the other views. Notice that the list shows only the first column, and the child items only affect the tree view. Try picking items with the Ctrl or Shift keys pressed (and then try it with both). Try picking a row from each view. When you select a row in the list, only the first column is selected. Try picking columns in the table (click the header) and see what happens in the other views. Make sure to pick the second column and watch the list view. Double-click any item and alter the text. QStandardItem objects are by default editable. Don t forget to experiment with the spacer bars.

<button targetElement="enabledButton"> <click> <invokeMethod target="setEnabled" method="evaluateIn" /> </click> </button>

this activity, and add a message box with ParallelLeft in it. Add two Code activities ParallelRight1 and ParallelRight2 to the right side of the Sequence activity within the Parallel activity. Generate Handlers for these two Code activities, and add a message box with the activity name in it. The code for these subs follows: Private Sub ParallelRight1_ExecuteCode(ByVal sender As System.Object, ByVal e As System.EventArgs) MsgBox("Parallel Right 1") End Sub Private Sub ParallelRight2_ExecuteCode(ByVal sender As System.Object, ByVal e As System.EventArgs) MsgBox("Parallel Right 2") End Sub Your completed StateInitialization activity for the LastState activity is shown in Figure 4-10.

The views and the standard model are flexible. You might not like some details in the application, so let s start looking at these details. You can start by setting some descriptive text in the headers: insert QStandardItems into the model by using setHorizontalHeaderItem(int, QStandardItem*) and setVerticalHeaderItem(int, QStandardItem*). Listing 5-5 shows the lines added to the main function to add horizontal headers. Listing 5-5. Adding headers to the standard item model model.setHorizontalHeaderItem( 0, new QStandardItem( "Name" ) ); model.setHorizontalHeaderItem( 1, new QStandardItem( "Phone number" ) );

Then there is the issue of the items being editable by the user. The editable property is controlled at the item level. By using the setEditable(bool) method on each child item shown in the tree view, you make them read-only (see the inner loop for it in Listing 5-6). Listing 5-6. Creating read-only items in a standard item model if( c == 0 ) for( int i=0; i<3; i++ ) { QStandardItem *child = new QStandardItem( QString("Item %1").arg(i) ); child->setEditable( false ); item->appendRow( child ); }

In this example, you will look at converting the data from one format to another, as well as at a two-way binding, where the binding maps in both directions. It isn t a case of changing one control to update another, as you saw earlier with the selection box updating the panel, but of either bound control updating the other. The page looks like Figure 5-5.

Sometimes it is helpful to limit the ways in which selections can be made. For example, you might want to limit the user to selecting only one item at a time (or to select only entire rows).

Figure 4-10. Completed StateInitialization activity for the LastState activity Again, add a breakpoint to the InitialState activity and debug the workflow. You ll see the workflow operations, much like you did with the Sequential workflow. The Sequence activity is executed first because it s part of the InitialState activity. Then, the control is given to the LastState activity, and the Parallel activity takes place. Notice how all activities within the Sequence and Parallel activity complete before moving to the next activity.

This limitation is controlled with the selectionBehavior and selectionMode properties of each view.
