New objects are added to drawings by dragging symbols from the palette onto the canvas. Figure 6 shows a Symbol tile being dragged into a drawing. When you drop the tile onto the canvas, PocketDraw copies the symbol into the drawing at the point where it was dropped.

Objects added to drawings are automatically aligned with the grid. The alignment occurs such that the upper left corner of the new object is snapped to the grid intersection closest to the upper left corner of the tile that was being dragged.

Palettes contain collections of symbols,usually grouped by functionality or purpose. While PocketDraw displays only one palette at a time, it supports the simultaneous use of many palettes.

Tapping the palette chooser pops up a list of available palettes. Tapping an item in the list selects it as the current working palette, replacing the previous selection. The name of the current working palette is always displayed in the palette chooser.

The limited size of the Pocket PC screen restricts the number of symbols displayed in the palette to five. However, the palette scroll bar can be used to move the view to any portion of a larger palette.

Palettes usually include popup tips that describe each symbol and its use. To see the popup for a symbol, tap-and-hold (but do not drag) the symbol in the palette. A small window describing the item will appear within a short time.
