The RTL based option creator is used
to instantiate the template rtl_tabset with a
Tk Window. The used creator window must have a
-class property.
Acceptable Tk Windows are: toplevel for floating windows, and frame for embedded windows.
See the options manual entry for details on the standard options.
List, what tabs are displayed inside the Rtl_tabset
Example 6.4. Rtl_tabset -show
# Create the tabset:
rtl_tabset .tabset ...
# Add tabs to the tabset:
.tabset add alpha ...
.tabset add beta ...
.tabset add gamma ...
.tabset add delta ..
# Hide the tab: beta,
# rearrange delta and gamma:
.tabset configure -show {alpha delta gamma }
The default shape and behavior for each tab. The tab type can be predefined / changed for all tabs.
Default value is rtl_tabItem. The tab type bundled with the tabset.
For altering the shape of tabs see also: »setformat«.
Dimension, defines how much two tabs overlap each other. Default value is »-5« (Tabs do overlap by 5 pixel).
Dimension, defines the minimal distance between then selected tab and the border of the tabset. This property is only used, when »-autovisible« is set. The first and last tabs are limited to »-borderspace«.
Default value is 50p (50 points).
Dimension, defines the distance from the first and last tab to the tabset border.
Default value is: 10 (10 pixel).
See also »-taboffset«.
Boolean value.
The selected tab is automatically moved in the visible region, when »-autovisible« is set to 1.
Boolean value. All tabs are centered in the visible region.
»-centered« is set under AQUA®.
Dimension, defines the distance of the limiting line to the tabs. The limiting line is rendered below the tabs, in an horizontal oriented tabset. Default value is -1 (-1 pixel), the tabs overlap with the limiting line by 1 pixel.
The »rtl_tabset« command creates a »rtl_tabset« window.
»rtl_tabset« is a canvas based composite tabset / notebook window. It is highly customizable. Either the individual tab design and the default design can be changed.
The standard design lets fade inactive tabs into the background of the tabset window. The tab background gets semi-transparent.
Each tab, features its own foreground and background colors. This colors are used when the tab is selected (front most). The tabset’s foreground color is used for any tab faded into the background.
Tabs (default is »rtl_tabItem«), are customizable, too.
TkPath is used, when available.
A Window created through the rtl_tabset command exposes various functions. Using these functions has the following general form:
object.option(?arg, arg, ...?)
PathName is the same as the window path name. Option and the args determine the exact behavior of the command. The following commands are possible for this window:
Returns the current value of the configuration option given by option. Option may have any of the values accepted by the rtl_tabset command.
Query or modify the configuration options of the window. 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 window 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 rtl_tabset command.

Removes the tab »item« from the tabset.
Allow a menu item equally behavior.
Setformat is intended to reformat the current tab outline. If no format is specified the horizontal or vertical definition from the private namespace will be used. Setformat is similar to other attributes but due it's extend not definable on the command line. NOTE: the given format must corrospond with the orientation of the tabset widget.
Bring the given item into the visible section. If the given item is already visible no action will be performed.
Called in from with an event handler for the <Map> event. Initial Version: roger 03/23/2007

Extends the tabset »path« with a new tab named »item«.
Send yview actions to the canvas widget
Center the tabs in tabset. See also »-centered«, needed for AQUA. Initial Version: roger 03/22/2007
Gives the current size of associated items.
Activate the given item. Flag is used to invoke the item. Since setselection is also used by other methods, flag will ensure not to notify the item about this internal stuff.
Query what kind of tabs are created. Related to »setformat«. This »type« is the same for all created tabs–except for tabs with an explicit defined type.
Secondary constructor for template rtl_tabset.
Creates focus keyboard handling. Please note, the »-takefocus« property from the canvas window must be set to 1 for proper focus management. The focus management depends on what sort of an item is used and has to be reimplemented for Tk canvas-only tabsets. Revision : 05/20/2009, Roger

Retrieve all tabs, known to the tabset. The tabset may contain hidden tabs (see the »-show« property), tabnames includes hidden tabs.
Send xview actions to the canvas widget
Used for the entire display stuff, also the contained child widget management widget will be replaced.
Locate the item underneath the mouse cursor.
Wrapper, access method for the included items. Note the used items need not to be of type rtl_tabItem. The items inside of a rtl_tabset have to be composed of the same template type and cannot being changed after an single item was added to the tabset.
