 * This widget manages one or more child widgets, exactly one of which is

/* Parameters:

 Name		     Class		RepType		Default Value
 ----		     -----		-------		-------------
 font		     Font		XFontStruct*	XtDefaultFont
 internalWidth	     Width		Dimension	4	*1
 internalHeight	     Height		Dimension	2	*1
 topWidget	     TopWidget		Widget			*2
 callback	     Callback		XtCallbackList	NULL	*3
 popdownCallback     Callback		XtCallbackList	NULL	*4
 selectInsensitive   SelectInsensitive	Boolean		True	*5
 beNiceToColormap    BeNiceToColormap	Boolean		False	*6
 topShadowContrast   TopShadowContrast	int		20
 bottomShadowContrast BottomShadowContrast int		40
 insensitiveContrast InsensitiveContrast int		33	*7

 background	     Background		Pixel		XtDefaultBackground
 border		     BorderColor	Pixel		XtDefaultForeground
 borderWidth	     BorderWidth	Dimension	1
 destroyCallback     Callback		Pointer		NULL
 hSpace 	     HSpace		Dimension	4
 height		     Height		Dimension	0
 mappedWhenManaged   MappedWhenManaged	Boolean		True
 orientation	     Orientation	XtOrientation	vertical
 vSpace 	     VSpace		Dimension	4
 width		     Width		Dimension	0
 x		     Position		Position	0
 y		     Position		Position	0

 Notes:

 1 internalWidth, internalHeight specify the margins around the text
   in the tabs.
 2 topWidget identifies the widget which is currently visible.
 3 callbacks are called whenever the user selects a tab.  Call_data is
   the new top widget.
 4 popdownCallbacks are called whenever the user selects a tab.  Call_data is
   the old (no longer visible) top widget.  Note that popdownCallbacks
   are called before callbacks.
 5 SelectInsensitive determines whether or not insensitive children may
   be selected anyway.
 6 BeNiceToColormap causes the Tabs widget to use fewer colors.
 7 InsensitiveContrast sets the contrast used for labels of insensitive widgets.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
