GUI Options

Embedding GUI Option Settings in Diagram Files

You may embed option settings, such as viewing modes, into your diagram files. A convenient usage is to override the default settings of your gui_setups file for specific diagrams.

For example, if your default has show-link-attributes off (which is a convenient setting for hardware files), you can turn link-attributes on for a DFG file by placing the following directive in your DFG file:

<OPTION> show_link_attr on </OPTION>

(Note the case of the <OPTION> / </OPTION> tags is important, and there must be white space after the <OPTION> tag.)

Most of the same settings available in the gui_setups file are also available for setting on a specific file basis. Specifically, the following are controllable:

	window_size_x     {#pixels}

	window_size_y     {#pixels}

	grid_size         {decimal-size}

	snap_to_grid      {yes/no}

	show_grid         {yes/no}

	show_node_names   {on/off}

	show_node_types   {on/off}

	show_node_attr    {on/off}

	show_port_names   {on/off}

	show_link_attr    {on/off}

	background_color  {black/dark-gray/medium-gray/light-gray/white}

	box_display_style {solid-box/plain-skeleton/3D-border/3D-solid/3D-shadow}

	nonsticky

Example:

<OPTION> grid_size = 0.05 </OPTION>
<OPTION> show_node_types off </OPTION>
<OPTION> show_node_attr on </OPTION>
<OPTION> show_port_names off </OPTION>
<OPTION> show_link_attr on </OPTION>
<OPTION> background_color = medium-gray </OPTION>
<OPTION> box_display_style = 3D-shadow </OPTION>

The options must be placed outside other blocks, one per line, in .sim or .dfg files.

Additional Options:

<NO_NET_EXTRACT/> - Prevents creating netinfo file when building simulation.
<WELD_PORT/> - Controls link-box attachment policy. Namely, under this mode, link attachment preserves to precise-point on box.
<FIXED_SCALE/> - Prevents ability to zoom in- and -out.
<SCALE_TEXT/> - Causes text to scale with zoom level.
<ARROW_SIZE sz="xx"/> - Sets arrow size to xx.
