The ltpal Button: Layer Palette

\epsfbox{ltpal.eps}

The Layer Palette is an adjunct to the layer table which provides a means for quick access to a few ``important'' layers, and prints information about layers. This is particularly useful when working with layouts containing a large number of layers.

The Layer Palette is brought up by pressing the small button marked with a blue square to the left of the scroll bar under the layer table.

The Layer Palette consists of three logical sections. The top section is a text area that displays some information about the layer currently or was last under the mouse pointer. The user can move the pointer over the layer icons in the layer table or the palette, and the palette will display the information. The information printed includes the long name a description of the layer, and the GDSII mapping layer/datatype numbers.

Below the text area is a dark area large enough for two rows of layer icons. The top row will contain the last few layers which were selected as the ``current'' layer. This row is automatically updated whenever the user selects a current layer by any means. The icons in this row can be dragged and clicked on in the same manner and same functionality as layers in the layer table.

The second row of layer icons will remain empty without user intervention. Layers can be dragged from the layer table or the first row, and dropped in this area, where they will remain. Thus, the user can drag their favorite layers to this area, and always have them close at hand. Again, these layers can be dragged and clicked on just as layers in the layer table.
