The image above shows the Single Row Mask Editor and it contains two tabs.

Single Row Mask Editor tabs

Layout Tree View

The Layout Tree View, displaying the hierarchical structure of the single row view, makes it easy to select layout items, especially those that are hidden by other items or that are small enough to grip them with the mouse. Selecting a tree element highlights the corresponding item in the single row view, and vice versa, and displays its properties in the Property Grid. For tree elements, you can invoke the context menu with common customization commands. Pressing the DELETE key deletes the selected layout item. Items can be dragged-and-dropped within the tree, and between the single row view and the tree.

Hidden Items

This pane displays hidden items, and supports drag-and-drop of the items to/from the single row view. Dragging an item from the single row view to the Hidden Items list hides this item, and dragging a hidden item to the single row view makes this item visible. When a hidden item is clicked, its properties are displayed, and can be modified in the Property Grid. In addition to hidden items, the Hidden Items list provides access to fixed items (the Empty Space Item, Label, Separator and Splitter), which appear first, and are painted bold. Actually these are not instances, but rather types of items.

Editor Features

The Single Row Mask Editor allows you to:

• Hide specific items and restore hidden items using drag-and-drop.
• Add Empty Space Items, labels, separators and splitters to the layout using drag-and-drop.
• Modify items' properties via the Property Grid.
• Access the hierarchical structure of the single row view, and modify it using drag-and-drop operations within the Layout Tree View.
