### DESCRIPTION

The tixExFileSelectBox command creates a new window (given by the pathName argument) and makes it into a ExFileSelectBox widget. Additional options, described above, may be specified on the command line or in the option database to configure aspects of the ExFileSelectBox such as its cursor and relief. The ExFileSelectBox widget is usually embedded in a tixExFileSelectDialog widget. It provides an convenient method for the user to select files. The style of the ExFileSelectBox widget is very similar to the standard file dialog in MS Windows 3.1.

### WIDGET COMMANDS

The tixExFileSelectBox command creates a new Tcl command whose window. This command may be used to invoke various operations on the widget. It has the following general form:

    pathName option ?arg arg ...?

PathName is the name of the command, which is the same as the args determine the exact behavior of the command. The following commands are possible for ExFileSelectBox widgets:

pathName cget option
  Returns the current value of the configuration option given by option. Option may have any of the values accepted by the tixExFileSelectBox command.

pathName configure ?option? ?value option value ...?
  Query or modify the configuration options of the widget. If no option is specified, returns a list describing all of the available options for pathName (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 widget option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the tixExFileSelectBox command.

pathName filter
  Forces the ExFileSelectBox widget to re-filter all the filenames according to the -pattern option.

pathName invoke
