set_window

Context: windows

Synopsis

Modifies the attributes of an existing window.

Syntax

set_window(attributes)
set_window(id, attributes)

Description

The function arguments.

Argument	Description
id	A ChipsId structure identifying the item, or a string containing the name of the object.
attributes	Configure object properties by giving an attribute string (a space-separated list of key=value pairs), list, dictionary, or a ChIPS object.

The set_window command sets the specified attributes to the provided values. The modified window becomes current. Multiple windows may be modified with a single command by setting the currency to "all".

Customizing the Window

There are several attributes that control the characteristics of windows. The set_window command may be used to modify the attribute values of an existing window at any time during a ChIPS session. See "ahelp attributes" and "ahelp setget" for more general information.

If multiple attributes are being set simultaneously and one of them fails, the entire command will fail and the window will not be modified.

Please see the section "Window Preferences and Attributes" below the examples for a list of the window attributes.

Note that the window title is not included in the attributes. To set the title, use the set_window_title command.

Certain window properties, such as height and width, can not be modified after the window is created. See "ahelp add_window" for more details on setting these properties when the window is created.

Advanced Functions

The module of advanced ChIPS functions contains other commands for setting attribute values (refer to "ahelp chips" for information on loading the module):

set_window_bgcolor
set_window_redraw

set_window_redraw is a boolean (see the Booleans section of "ahelp chipsopt") that determines whether the window is updated as each command is executed. The default value is True.

Examples

Example 1

chips> clear()
chips> add_curve(x, y, ["window.display", False, "symbol.style",
"none"])
chips> set_plot_xlabel(r"Wavelength (\AA)")
chips> set_plot_ylabel("Flux (erg cm^{-2} s^{-1})")
chips> log_scale()
chips> set_window(["display", True])

The add_curve call creates a window, due to the call to clear, ands sets its display attribute to False, which means that no window will be visible on screen. Several changes are made to the plot - axis labels added and both axes set to use a logarithmic scale - before the final set_window call changes the display setting back to True. At this point the window and its contents become visible, and any future changes to the visualization will be immediately reflected on screen.

Example 2

chips> add_window()
chips> set_window(["bgcolor", "blue"])

Using an attribute/value pair, set the window background color to blue.

Example 3

chips> set_window({"bgcolor": "blue"})

Use a dictionary, rather than a list, to change the bgcolor attribute of the window.

Example 4

chips> add_window()
chips> ws = ChipsWindow()
chips> ws.bgcolor = "blue"
chips> set_window (ws)

Using a ChIPS window attribute object, set the window background color to blue.

Example 5

chips> add_window(5, 8, "inches", ["bgcolor", "navy"])
chips> set_window("bgcolor=green")

Add a window with a navy background, then use a list to change it to green.

Window Preferences and Attributes

The attributes associated with windows are given in the following table, where the "Set?" column refers to whether the attribute can be changed using the set_window() command. To change the window preference settings prepend "window." to the attribute name.

Attribute	Description	Options	Default	Set?
bgcolor	Background Color of the window	name or hex; see the Color section of "ahelp chipsopt"	default: white in the ChIPS window, black on printout	Yes
display	Flag indicating whether the window should be rendered	see the Booleans section of "ahelp chipsopt"	true	Yes
geom	A geometry hint to the window manager to say where the ChIPS window should be created (this setting may be ignored, depending on the window manager in use). The format is either a blank string or a string containing two signed integers such as "+100+50", "+0+20", or "+0+0".			No
grid.color	The color to draw the grid lines.	name or hex; see the Color section of "ahelp chipsopt"	default	No
grid.scale	Where should the grid lines be drawn?	One of quarterinch, halfinch, cm, or normalized (spacing of a tenth of the window width/height). These can also be specified as default (for quarterinch) or the enumerations 0, 1, 2, 3, 4 for default, quarterinch, halfinch, cm, normalized respectively.	quarterinch	No
grid.style	The style used to draw the grid lines.	see the Line Style section of "ahelp chipsopt"	longdash	No
grid.thickness	The thickness used to draw the grid lines.	0.5 to 10.0; see the Thickness section of "ahelp chipsopt"	1	No
grid.visible	Should the grid be visible or not.	see the Booleans section of "ahelp chipsopt"	false	No
height	window height	Numerical value expressed in either inches, centimeters, millimeters or pixels	360 pixels	No
scaleheight	factor to scale window to display at approximate height	positive floating point value	1.25	No
scalewidth	factor to scale window to display at approximate width	positive floating point value	1.25	No
smoothing	use VTK's smoothing to reduce anti-aliasing	see the Booleans section of "ahelp chipsopt"	true	No
stem	Stem used for window id	An alpha-numeric character sequence that does not contain a space	win	No
prefix	Prefix added to window id to create the text that the window manager may use to label the ChIPS window.		"chips - "	No
units	Units of the window width and height dimensions	inches\|cm\|mm\|pixels	pixels	No
width	window width	Numerical value expressed in either inches, centimeters, millimeters or pixels	360 pixels	No
