CW_TMPL

CW_TMPL

The CW_TMPL procedure is a template for compound widgets that use the XMANAGER. Use this template instead of writing your compound widgets from “scratch”. This template can be found in the file cw_tmpl.pro in the lib subdirectory of the IDL distribution.

Syntax


Result = CW_TMPL( Parent [, TAB_MODE=value] [, UNAME=string] [, UVALUE=value] )

Arguments


Parent

The widget ID of the parent widget of the new compound widget.

Keywords


TAB_MODE

Set this keyword to one of the values shown in the table below to determine how the widget hierarchy can be navigated using the Tab key. The TAB_MODE setting is inherited by lower-level bases and child widgets unless it is explicitly set on an individual widget.

Note: It is not possible to tab to disabled (SENSITIVE=0) or hidden (MAP=0) widgets.

Valid settings are:

Value

Description

0

Disable navigation onto or off of the widget. This is the default. Child widgets automatically inherit the tab mode of the parent base as described in Inheriting the TAB_MODE Value.

1

Enable navigation onto and off of the widget.

2

Navigate only onto the widget.

3

Navigate only off of the widget.

Note: In widget applications on the UNIX platform, the Motif library controls what widgets are brought into and released from focus using tabbing. The TAB_MODE keyword value is always zero, and any attempt to change it is ignored when running a widget application on the UNIX platform. Tabbing behavior may vary significantly between UNIX platforms; do not rely on a particular behavior being duplicated on all UNIX systems.

UNAME

Set this keyword to a string that can be used to identify the widget in your code. You can associate a name with each widget in a specific hierarchy, and then use that name to query the widget hierarchy and get the correct widget ID.

To query the widget hierarchy, use the WIDGET_INFO function with the FIND_BY_UNAME keyword. The UNAME should be unique to the widget hierarchy because the FIND_BY_UNAME keyword returns the ID of the first widget with the specified name.

UVALUE

A user-specified value for the compound widget.
