# WV_APPLET

The WV_APPLET procedure runs the IDL Wavelet Toolkit graphical user interface.

## Examples

WV_APPLET, TOOLS=['Renormalize','My Tool']

The above statement will start up the Wavelet Toolkit, and add the user tools `'``Renormalize``'` and `'``My Tool``'` to the Tools menu. When these are selected the actual functions that will be called are WV_TOOL_RENORMALIZE and WV_TOOL_MYTOOL.

## Syntax

WV_APPLET [, Input] [, ARRAY=array] [, GROUP_LEADER=widget_id] [, /NO_SPLASH] [, TOOLS=string array] [, WAVELETS=string or string array]

## Arguments

### Input

Input can be either a string giving the name of a Wavelet toolkit save file, or a one- or two-dimensional array of data. If Input is not specified, then the sample file `wv_sample.sav` is opened. If Input is set to an empty string (`''`) then the Wavelet toolkit is started with an empty dataset.

## Keywords

### ARRAY

Set this keyword to a one- or two-dimensional array of data to be imported into the Wavelet toolkit upon startup. If argument Input is set to a filename then ARRAY will be added to the list of variables.

### GROUP_LEADER

The widget ID of an existing widget that serves as group leader for the newly-created widget. When a group leader is killed, for any reason, all widgets in the group are also destroyed.

A given widget can be in more than one group. The WIDGET_CONTROL procedure can be used to add additional group associations to a widget. For more information, see WIDGET_CONTROL. It is not possible to remove a widget from an existing group.

### NO_SPLASH

If this keyword is set then the splash screen will not be displayed on startup.

### TOOLS

A scalar string or vector of strings giving the names of user-defined functions to be included in the WV_APPLET Tools menu. The actual function names are constructed by removing all white space from each name and attaching a prefix of WV_TOOL_.

### WAVELETS

A scalar string or vector of strings giving the names of user-defined wavelet functions to be included in WV_APPLET. The actual function names are constructed by removing all white space from each name and attaching a prefix of WV_FN_.
