AHELP for CIAO 4.6 ChIPS v1

display_region

Context: regions

Synopsis

Display the specified region.

Syntax

display_region()
display_region(id)

Description

The function arguments.

Argument Description
id A ChipsId structure identifying the item, or a string containing the name of the object.

If no argument is given then the current region is shown, otherwise the argument determines what to show.

Example 1

chips> add_region(3, .7, .7, .2, "id=tri")
chips> hide_region("tri")
chips> display_region()

Create a region and hide it, then display the current region.

Example 2

chips> add_region(4, .5, .5, .4, "id=square")
chips> set_region("square", ["edge.color", "white", "fill.color",
"blue", "fill.style", "1"])
chips> hide_region("square")
chips> add_region(6, .5, .5, .1, "id=hex")
chips> set_region("hex", ["edge.color", "white", "edge.thickness", 2])
chips> id = ChipsId()
chips> id.region = "square"
chips> display_region(id)

Two regions are created; the second region is current after it is created. The id.region command sets the region value of the ChipsId structure to the first region. That region is then displayed.

Example 3

chips> add_region(4, .5, .5, .4, "id=square")
chips> add_region(6, .5, .5, .1, "id=hex")
chips> hide_region("all")
chips> display_region("all")

Two regions are created and hidden, then the display_region command displays them both.
