\subsection{Tix Commands}

\begin{classdesc}{tixCommand}{}

The \ulink{tix commands}

{http://tix.sourceforge.net/dist/current/man/html/TixCmd/tix.htm}

provide access to miscellaneous elements of \refmodule{Tix}'s internal

state and the \refmodule{Tix} application context. Most of the information

manipulated by these methods pertains to the application as a whole,

or to a screen or display, rather than to a particular window.

To view the current settings, the common usage is:

\begin{verbatim}

\end{verbatim}

\end{classdesc}

\begin{methoddesc}{tix_configure}{\optional{cnf,} **kw}

Query or modify the configuration options of the Tix application

context. If no option is specified, returns a dictionary all of the

available options. If option is specified with no value, then the

method returns a list describing the one named option (this list will

be identical to the corresponding sublist of the value returned if no

option is specified). If one or more option-value pairs are

specified, then the method modifies the given option(s) to have the

given value(s); in this case the method returns an empty string.

Option may be any of the configuration options.

\end{methoddesc}

\begin{methoddesc}{tix_cget}{option}

Returns the current value of the configuration option given by

\var{option}. Option may be any of the configuration options.

\end{methoddesc}

\begin{methoddesc}{tix_getbitmap}{name}

Locates a bitmap file of the name \code{name.xpm} or \code{name} in

one of the bitmap directories (see the \method{tix_addbitmapdir()}

method). By using \method{tix_getbitmap()}, you can avoid hard

coding the pathnames of the bitmap files in your application. When

successful, it returns the complete pathname of the bitmap file,

prefixed with the character \samp{@}. The returned value can be used to

configure the \code{bitmap} option of the Tk and Tix widgets.

\end{methoddesc}

\begin{methoddesc}{tix_addbitmapdir}{directory}

Tix maintains a list of directories under which the

\method{tix_getimage()} and \method{tix_getbitmap()} methods will

search for image files. The standard bitmap directory is

\file{\$TIX_LIBRARY/bitmaps}. The \method{tix_addbitmapdir()} method

adds \var{directory} into this list. By using this method, the image

files of an applications can also be located using the

\method{tix_getimage()} or \method{tix_getbitmap()} method.

\end{methoddesc}

\begin{methoddesc}{tix_filedialog}{\optional{dlgclass}}

Returns the file selection dialog that may be shared among different

calls from this application. This method will create a file selection

dialog widget when it is called the first time. This dialog will be

returned by all subsequent calls to \method{tix_filedialog()}. An

optional dlgclass parameter can be passed as a string to specified

what type of file selection dialog widget is desired. Possible

options are \code{tix}, \code{FileSelectDialog} or

\code{tixExFileSelectDialog}.

\end{methoddesc}

\begin{methoddesc}{tix_getimage}{self, name}

Locates an image file of the name \file{name.xpm}, \file{name.xbm} or

\file{name.ppm} in one of the bitmap directories (see the

\method{tix_addbitmapdir()} method above). If more than one file with

the same name (but different extensions) exist, then the image type is

chosen according to the depth of the X display: xbm images are chosen

on monochrome displays and color images are chosen on color

displays. By using \method{tix_getimage()}, you can avoid hard coding

the pathnames of the image files in your application. When successful,

this method returns the name of the newly created image, which can be

used to configure the \code{image} option of the Tk and Tix widgets.

\end{methoddesc}

\begin{methoddesc}{tix_option_get}{name}

Gets the options manitained by the Tix scheme mechanism.

\end{methoddesc}

\begin{methoddesc}{tix_resetoptions}{newScheme, newFontSet\optional{,

newScmPrio}}

Resets the scheme and fontset of the Tix application to

\var{newScheme} and \var{newFontSet}, respectively. This affects only

those widgets created after this call. Therefore, it is best to call

the resetoptions method before the creation of any widgets in a Tix

application.

The optional parameter \var{newScmPrio} can be given to reset the

priority level of the Tk options set by the Tix schemes.

Because of the way Tk handles the X option database, after Tix has

been has imported and inited, it is not possible to reset the color

schemes and font sets using the \method{tix_config()} method.

Instead, the \method{tix_resetoptions()} method must be used.
