Select the wxFrame1 tab in the Editor to ensure that we are editing the
Frame.
Start the Designer, by selecting the designer button from the Editor toolbar.
The Frame will be displayed as a drawing area. A new pane will be displayed
in the Editor called the 'Data' pane.
The Inspector Window will display the 'Constructor pane'. This pane edits
the size, position, style, variable name and title of a component. Edit
the field called 'Title'. Give the frame the name 'Notebook'.
The changes must be saved into the application source code. You save the
changes using the 'Post' button. Press the 'Post' button on the Inspector
toolbar. The Designer Windows will close.
You will notice that the source code has been updated to reflect the title.
The Editor shows that the Source Code is changed by asterix on the notebook
tabs.
