The default object palette contains a very minimal set of types provided by the QtQuick module. To access a richer set of controls, we need to add an import directive to our document. To do this, locate the Library pane in the top-left corner of the window and go to its Imports tab. Next, click on Add Import and select QtQuick.Controls 2.2 in the drop-down list. The selected import will appear in the tab. You can click on the × button to the left of the import to remove it. Note that you cannot remove the default import.
