Chapter 24  UI Assistant Parts Toolbar 
The Parts page gives you quick and easy access to all of the parts found on the Composition Editor’s palette. As a result, you may hide the palette in order to conserve screen real estate. As all of the common visual parts are directly accessible from this page, you may find this page to be a more convenient mechanism for choosing part types (e.g., you don’t need to switch between categories to access labels, buttons and lists).
The ability to automatically invoke sticky mode via Alt-clicking on any of the buttons means that you can avoid frequent trips to the Sticky checkbox. If the Auto Sticky property is set (via the Setup Page), then all part adding functions will use sticky mode.
In addition to the most common visual parts that are directly accessible from this page, quite a few others are available by resizing the UI Assistant window (in floating mode only).
Selection Tool
 

	Selection Tool. Use this button to set the Composition Editor back to selection mode. This will turn off sticky mode if it is on.

Parts ComboBoxes
 
The combobox on the right is a list of all of the parts categories in use by the Composition Editor. The default category is “** All **”. The combobox on the right is used to select a part from the selected category. The button on the right loads the cursor with an instance of the selected part. Alt-clicking the button automatically invokes sticky mode.
Right-click on the right-hand combobox for a list of available parts in the selected category.
