Tix Built-In Commands - tix manual page

This manual page descripts the tix command, which manipulates the internal states of the Tix library. If you're looking for a general introduction to the Tix library, please refer to the TixIntro manual page.

The Tix application context supports the following configuration options. Usually, these options are set using the X resource database, i.e., in the user's .Xdefault file. For example, to choose a different color scheme for the Tix widgets, these two lines can be added to the user's .Xdefault file:

*TixScheme:  Gray
*TixFontSet: 14Point

Command-Line Name: -binding
Database Name: binding
Database Class: Binding: This is an obsolete option.
Command-Line Name: -debug
Database Name: debug
Database Class: Debug: Specifies whether the Tix widgets should run in debug mode.
Command-Line Name: -fontset
Database Name: tixFontSet
Database Class: TixFontSet: Specifies the fontset to use for the Tix widgets. Valid options are WmDefault, TK, TkWin, 12Point and 14Point. TK specifies that the standard TK fonts should be used. The default value is WmDefault.
Command-Line Name: -scheme
Database Name: tixScheme
Database Class: TixScheme: Specifies the color scheme to use for the Tix widgets. Valid options are WmDefault, TK, TkWin, Gray, Blue, Bisque, SGIGray and TixGray. If you want the standard TK color scheme, you can use the value TK. The default value is WmDefault. '#92;"----------END
Command-Line Name: -schemepriority
Database Name: tixSchemePriority
Database Class: TixSchemePriority: Specifies the priority level of the TK options set by th Tix schemes. Please refer to the TK option manual page for a discussion of the priority level of Tix options. The default value is 79, which makes the Tix schemes at a higher priority than the settings in the .Xdefaults file. If you want to allow the Tix schemes to be overridden by the settings in the .Xdefaults file, you can set the following line in you .Xdefaults file:

*TixSchemePriority: 21

DESCRIPTION

The tix command provides access to miscellaneous elements of Tix's internal state and the Tix application context. Most of the information manipulated by this command pertains to the application as a whole, or to a screen or display, rather than to a particular window. The command can take any of a number of different forms depending on the option argument. The legal forms are:

tix addbitmapdir directory

Tix maintains a list of directory under which which the tix getimage and tix getbitmap commands will search for image files. The standard bitmap directory is $TIX_LIBRARY/bitmaps. The addbitmapdir command adds directory into this list. By using this command, the image files of an applications can also be located using the tix getimage ot tix getbitmap command.

tix cget option

Returns the current value of the configuration option given by option. Option may be any of the options described in the CONFIGURATION OPTIONS section.

tix configure ?option? ?value option value ...?

Query or modify the configuration options of the Tix application context. If no option is specified, returns a list describing all of the available options (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, then the command 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 command modifies the given option(s) to have the given value(s); in this case the command returns an empty string. Option may be any of the options described in the CONFIGURATION OPTIONS section.

tix filedialog ?class?

Returns the file selection dialog that may be shared among different modules of this application. This command will create a file selection dialog widget when it is called the first time. This dialog will be returned by all subsequent calls to tix filedialog. An optional class parameter can be passed to specified what type of file selection dialog widget is desired. Possible options are tixFileSelectDialog or tixExFileSelectDialog.

tix getbitmap name

Locates a bitmap file of the name name.xpm or name in one of the bitmap directories (see the addbitmapdir command above). By using tix getbitmap, you can advoid 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 @. The returned value can be used to configure the -bitmap option of the TK and Tix widgets.

tix getimage name

Locates an image file of the name name.xpm, name.xbm or name.ppm in one of the bitmap directories (see the addbitmapdir command 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 tix getimage, you can advoid hard coding the pathnames of the image files in your application. When successful, this command returns the name of the newly created image, which can be used to configure the -image option of the TK and Tix widgets.

tix option ?args ...?

Manipulates the options manitained by the Tix scheme mechanism. Available options are:

active_bg   active_fg   bg
bold_font   dark1_bg    dark1_fg
dark2_bg    dark2_fg    disabled_fg
fg          fixed_font  font    
inactive_bg inactive_fg input1_bg    
input2_bg   italic_font light1_bg
light1_fg   light2_bg   light2_fg
menu_font   output1_bg  output2_bg
select_bg   select_fg   selector

The arguments to the tix option command can take the following form(s):

tix option get option: Returns the current value of option.

tix resetoptions newScheme newFontSet ?newScmPrio?

Resets the scheme and fontset of the Tix application to newScheme and newFontSet, respectively. This affects only those widgets created after this call. Therefore, it is best to call the resetoptions command before the creation of any widgets in a Tix application. The optional parameter newScmPrio can be given to reset the priority level of the TK options set by the Tix schemes.

BUGS

[1]

In this release of Tix, the following configuration options have been disabled. Assigning values to them will cause no effect:

-binding
-debug
-fontset
-scheme
-schemepriority

In addition, the following options to the tix command have been disabled. Invoking the tix command with these options will cause no effect:

resetoptions

[2]

Because of the way TK handles the X option database, after tixwish has started up, it is not possible to reset the color schemes and font sets using the tix config command. Instead, the tix resetoptions command must be used.

The tk_setPalette command does not work very well under Tix. To use it, one must follow these steps:

tix resetoptions TK TK
tk_setPalette lightblue
